A Royal Inspiration, Reimagined: Meghan Markle’s Zucchini Bolognese

Many of you have asked for a faster, more robust version of Meghan Markle’s famous zucchini bolognese recipe—the one celebrated for its simplicity but notorious for its lengthy, over four-hour cooking time. We heard your requests loud and clear! Inspired by her genius, we’ve developed this incredibly simple yet profoundly delicious, Whole30-friendly Instant Pot Zucchini Bolognese. It drastically cuts down on cooking time and, crucially, adds a substantial amount of meat, making it perfectly suited for paleo, keto, and low-carb diets.

A wholesome and satisfying meal, ready faster than ever.

Before stepping into her role as a Duchess, Meghan Markle was more than just an actress; she was also a passionate food and lifestyle blogger. Among her many culinary revelations, her zucchini pasta sauce quickly became a viral sensation after her wedding. The original recipe featured zucchini (or courgettes, for our British friends), onions, olive oil, water, and a bouillon cube. The secret to its acclaimed creamy texture, according to Meghan, was a patient, low-and-slow simmer for approximately four hours.

While the traditional method promises a delightful result, the reality of modern life often leaves little room for four hours of stovetop supervision. This is where our reimagined version steps in, offering the same creamy, dreamy sauce experience but with the convenience and speed that today’s busy schedules demand. It’s an ideal recipe if you find yourself with an abundance of zucchini from your garden, transforming a simple vegetable into a gourmet, time-saving meal.

The Power of the Instant Pot: Speed and Flavor Unleashed

In our fast-paced world, who truly has four hours to dedicate to “babysitting” a pot on the stove? (Certainly not Meghan Markle these days, we’d imagine!) When our readers began asking for an Instant Pot solution to Meghan’s time-consuming recipe, we knew it was time to innovate. Our mission was clear: create a Whole30-friendly version that dramatically reduces the cooking time while also enhancing its nutritional value. The solution involved not only harnessing the power of the Instant Pot but also adding a generous amount of protein to transform this side dish into a complete, satisfying meal. Hence, the “meatier” twist – a delicious pun intended!

The Instant Pot, a modern kitchen marvel, truly shines in recipes like this. Its pressure cooking function allows ingredients to tenderize and flavors to meld together in a fraction of the traditional time. This means you can achieve that deeply developed, slow-cooked taste without the long wait. The sealed environment of the Instant Pot also ensures that moisture and nutrients are locked in, resulting in a richer, more intensely flavored bolognese sauce. It’s the ultimate tool for busy home cooks who crave wholesome, homemade meals without the extensive time commitment.

Wholesome, Keto, Whole30, and Paleo Perfection: Your New Favorite Bolognese

After numerous delicious (and some not-so-delicious) attempts, we finally perfected this simple and utterly delectable Instant Pot Zucchini Bolognese recipe. Our key upgrades include replacing generic, often chemical-laden bouillon cubes with our signature umami-packed Magic Mushroom Powder. This unique blend infuses the sauce with incredible depth and savoriness, without any artificial additives. To transform the dish into a complete and robust meal, we incorporated a full pound of high-quality bulk Italian sausage, significantly boosting its protein content and making it deeply satisfying.

This hearty bolognese is not just delicious but also a versatile option for various healthy eating plans.

The best part? This entire recipe, from start to finish, can be prepared in under an hour using your Instant Pot. This makes it an ideal choice for busy weeknights when you want a homemade, healthy meal without compromising on flavor or your dietary goals. Whether you’re following a Whole30, Keto, or Paleo lifestyle, this Zucchini Bolognese is a guilt-free pleasure. It’s also incredibly family-friendly, offering a nutritious and delicious alternative to traditional pasta dishes that even the pickiest eaters will enjoy. We’re absolutely thrilled with this creation!

Adaptable & Delicious: Slow Cooker and Stovetop Alternatives

While the Instant Pot offers unparalleled speed and convenience, we understand that not everyone has one, or you might prefer other cooking methods. The good news is, this Zucchini Bolognese recipe is wonderfully versatile and can absolutely be made in a slow cooker or on the stovetop. Just be prepared for a longer cooking duration to achieve that perfect tender zucchini and melded flavor!

Slow Cooker Instructions: Set It and Forget It

For a hands-off approach, you can easily adapt this recipe for your slow cooker. Begin by sautéing the diced onions and Italian sausage in a separate skillet until the sausage is no longer pink and the onions are softened. This crucial step helps to build a rich flavor base that pressure cooking would achieve instantly. Once sautéed, transfer the onion and sausage mixture to your slow cooker. Add the diced zucchini, minced garlic, and Magic Mushroom Powder (or seasoned salt with umami boosters). Give everything a good stir to combine. Program your slow cooker to cook on low for 6 to 8 hours, or until the zucchini has become exceptionally tender and easily mashes into a sauce. The longer cooking time allows the flavors to deepen beautifully, creating a wonderfully comforting bolognese.

Stovetop Instructions: The Traditional Approach

If you prefer the classic stovetop method, simply follow the initial sautéing directions as outlined in the Instant Pot section, but perform all steps in a large saucepan or a Dutch oven over medium heat. Start by sautéing the onions until soft, then brown the Italian sausage, breaking it up as it cooks. Once the sausage is cooked through, add the diced zucchini, minced garlic, and seasoning (Magic Mushroom Powder or kosher salt with umami boosters). Stir all the ingredients together thoroughly. Increase the heat to bring the mixture to a gentle boil, then immediately reduce the heat to a low simmer. Cover the pot and allow it to cook for 3 to 4 hours, or until the zucchini completely breaks down and forms a thick sauce. Remember to stir occasionally to prevent sticking and ensure even cooking. If the sauce appears too dry at any point, add a small splash of broth or water to maintain the desired consistency. This method rewards patience with a deeply flavorful and satisfying bolognese.

Crafting Your Zucchini Bolognese: Essential Ingredients

Creating this delicious and healthy Instant Pot Zucchini Bolognese requires a few key ingredients, each playing a vital role in building the dish’s incredible flavor and texture. Here’s a closer look at what you’ll need:

  • Extra Virgin Olive Oil or Avocado Oil: These healthy fats are essential for sautéing our aromatics and sausage, establishing the foundational flavors of the bolognese. Choose a high-quality oil for the best results.
  • Yellow Onion: A staple in many savory dishes, yellow onion provides a sweet and pungent base. Dicing it finely ensures it breaks down smoothly into the sauce, adding depth without large chunks.
  • Bulk Italian Sausage: This is where our bolognese gets its heartiness and a significant flavor boost. For Whole30 compatibility, ensure your chosen sausage is free from added sugars, nitrates, and other non-compliant ingredients. Alternatively, you can easily make your own flavorful homemade Italian sausage following our simple recipe.
  • Zucchini: The star of the show! Zucchini serves a dual purpose in this recipe: it cooks down to create the creamy, vegetable-rich sauce, and extra zucchini is spiralized to form the “spaghetti” noodles. This makes it an ideal recipe for when your garden (or local market) is overflowing with this versatile squash. Look for firm, medium-sized zucchinis.
  • Garlic Cloves: Freshly minced garlic adds an indispensable aromatic pungency that complements the sausage and zucchini beautifully. Don’t skimp on the garlic for maximum flavor!
  • Magic Mushroom Powder or Diamond Crystal brand kosher salt: Our Magic Mushroom Powder is a secret weapon for adding deep, savory umami to any dish. If you don’t have it, a good quality kosher salt can be used, but you might want to enhance the umami with a few drops of fish sauce or a couple of dried mushrooms (rehydrated and minced) added to the pot, as detailed in the instructions. This is crucial for rounding out the flavor profile.
  • Freshly Squeezed Lemon Juice: A bright finish of fresh lemon juice is what elevates this bolognese from good to great. It cuts through the richness, brightens the flavors, and adds a refreshing tang that balances the entire dish.

Your Guide to a Speedy & Delicious Instant Pot Zucchini Bolognese

Making this hearty Zucchini Bolognese in your Instant Pot is surprisingly straightforward and incredibly rewarding. Follow these simple steps for a perfect meal every time:

  1. Initiate Sauté Mode: Begin by grabbing your Instant Pot or pressure cooker. Select the Sauté function and allow the metal insert to heat up sufficiently. Once hot, pour in your chosen extra virgin olive oil or avocado oil.

  2. Sauté the Onions: Add the diced yellow onions to the hot oil. Cook, stirring frequently with a silicone spatula, for 2 to 3 minutes, or until the onions begin to soften and become translucent. This step builds a foundational layer of flavor.

  3. Brown the Italian Sausage: Add the bulk Italian sausage to the pot. Using your silicone spatula, break the sausage into smaller pieces as it cooks. Continue to cook, stirring occasionally, until the sausage is thoroughly browned and no longer pink. This browning step is vital for developing rich, savory flavors.

  4. Add Remaining Ingredients: Now, add the diced zucchini and minced garlic to the pot. Sprinkle in 1 teaspoon of Magic Mushroom Powder or Diamond Crystal brand kosher salt. If using plain kosher salt, you can boost the umami by adding a few drops of fish sauce or a couple of rehydrated and minced dried mushrooms for extra savoriness. Stir everything together thoroughly to combine all the flavors.

  5. Pressure Cook: You do not need to add any extra liquid to the pot. The zucchini will release enough natural liquid during pressure cooking to create the sauce and ensure the Instant Pot can come to high pressure safely. Lock the lid securely on your Instant Pot, making sure the sealing valve is in the “Sealing” position. Program it to cook for 35 minutes under high pressure.

  6. Release Pressure: Once the cooking cycle is complete, you have two options for releasing the pressure. You can either allow the pressure to release naturally (NPR), which takes about 10-15 minutes, or you can manually vent it (QR) by carefully turning the sealing valve to the “Venting” position if you’re eager to serve. Be cautious of the hot steam.

  7. Mash and Form Sauce: Open the lid. The zucchini and onions should be incredibly tender, almost falling apart. Use your silicone spatula or a potato masher to easily mash them directly in the pot, forming a thick, chunky, and irresistible bolognese sauce.

  8. Season and Finish: Taste the bolognese and adjust the seasoning as needed with additional Magic Mushroom Powder, salt, or freshly ground black pepper. Finally, stir in the juice from half a lemon. Taste it again—the lemon adds a crucial bright finish that really makes the flavors pop! (Always, always, ALWAYS taste your food and season accordingly; your palate is the best judge!)

  9. Prepare Zucchini Noodles: While your sauce is finishing, grab a spiralizer to prepare some fresh zucchini noodles (zoodles). If you’re short on time, many grocery stores now offer ready-to-go spiralized vegetables. If serving immediately on zoodles, simply drop the raw spiralized zucchini directly into the hot bolognese and toss them gently until the heat of the sauce softens them to your desired al dente consistency. No need to cook them separately!

  10. Serve and Enjoy: Garnish your delicious Instant Pot Zucchini Bolognese with your favorite fresh herbs, such as parsley or basil, for an extra burst of flavor and color. Then, dig in and savor your wholesome, quick, and incredibly satisfying meal! This versatile sauce also freezes exceptionally well, so don’t hesitate to make a larger batch whenever your vegetable crisper is overflowing with fresh zucchini.

Creative Ways to Enjoy Your Zucchini Bolognese

The beauty of this meaty Zucchini Bolognese lies not just in its ease of preparation but also in its incredible versatility. While it’s perfectly crafted to be Whole30, Paleo, and Keto-friendly, you have endless options for how to serve it, adapting to various preferences and dietary needs. You’ll be genuinely amazed at how flavorful and simple it is!

Our go-to serving method, especially when we have an abundance of zucchini, is to spiralize one medium zucchini per person just before serving. We then toss these fresh, raw zoodles directly into the hot bolognese sauce. The residual heat from the sauce is typically enough to gently soften the zucchini noodles to a perfect al dente texture, allowing them to soak up all the rich flavors without becoming soggy. This method keeps the meal light, fresh, and perfectly low-carb.

However, your choices don’t stop there! This robust sauce pairs beautifully with:

  • Other Veggie Noodles: Experiment with sweet potato noodles, carrot noodles, or even spaghetti squash for a nutrient-dense, gluten-free base.
  • Gluten-Free Pasta: If you’re avoiding gluten but still crave a more traditional pasta experience, serve this bolognese over your favorite gluten-free pasta.
  • Regular Pasta: For those not following a strict Paleo or Keto diet, this bolognese is absolutely divine over traditional wheat pasta. We promise not to tell anyone of your Paleo heresy!
  • Steamed Vegetables: Spoon the bolognese over steamed broccoli, green beans, or cauliflower rice for an extra boost of vegetables.
  • Baked Potatoes or Sweet Potatoes: For a heartier, comforting meal, top a baked potato or sweet potato with a generous serving of this bolognese.
  • As a Hearty Bowl: Enjoy it simply in a bowl, perhaps with a sprinkle of nutritional yeast for a cheesy flavor (if Whole30 compliant) or fresh herbs.

No matter how you choose to serve it, this Instant Pot Zucchini Bolognese is destined to become a staple in your meal rotation for its taste, speed, and health benefits.

Maximizing Your Meal Prep: Storing Zucchini Bolognese

This Instant Pot Zucchini Bolognese is not only perfect for a fresh meal but also an excellent candidate for meal prepping. Its flavors tend to deepen beautifully over time, making leftovers just as delicious, if not more so, than the freshly prepared dish. Proper storage ensures you can enjoy this wholesome meal throughout the week or save it for a busy future day.

  • Refrigeration: Any leftover Zucchini Bolognese sauce can be stored safely in a sealed, airtight container in the refrigerator for up to 4 days. When ready to reheat, simply warm gently on the stovetop over medium-low heat or in the microwave until heated through. If the sauce has thickened too much, you can add a tablespoon or two of water or broth to loosen it.
  • Freezing: For longer storage, this bolognese freezes exceptionally well. Transfer the cooled sauce into freezer-safe airtight containers or heavy-duty freezer bags. If using bags, lay them flat for efficient freezing and easier stacking. The sauce can be stored in the freezer for up to 3 months. When you’re ready to enjoy, thaw the sauce overnight in the refrigerator, then reheat as described above. This makes it a fantastic option for batch cooking, ensuring you always have a delicious, healthy meal on hand during hectic times.

Preparing a double batch of this bolognese is a smart strategy to save time and effort in the long run. You’ll thank yourself later when a flavorful, homemade meal is just a thaw and reheat away!

This simple and quick Whole30-friendly Instant Pot Zucchini Bolognese recipe is a riff on Meghan Markle’s original version, but a whole lot meatier!

Ingredients

  • 2 tablespoons extra virgin olive oil or avocado oil
  • 1 large yellow onion, diced
  • 1 pound bulk Italian sausage
  • 1½ pounds zucchini, diced into ½-inch pieces
  • 3 garlic cloves, minced
  • Magic Mushroom Powder or Diamond Crystal kosher salt (with added umami boosters detailed in the instructions)
  • Juice from ½ lemon

Instructions

  1. Grab your Instant Pot or pressure cooker and turn on the Sauté function. When the metal insert is hot, pour in the olive oil.
  2. Toss in the diced onions and cook, stirring frequently, for 2 to 3 minutes or until slightly softened.
  3. Add the Italian sausage and break it up with a silicone spatula. Cook the sausage until it’s no longer pink.
  4. Dump in the zucchini, minced garlic, and 1 teaspoon of Magic Mushroom Powder or Diamond Crystal brand kosher salt. (The salt won’t add extra umami, so you may want to add a few drops of fish sauce or a couple of dried mushrooms to the pot for extra savoriness.) Stir well.
  5. You don’t need to add any extra liquid. Trust me—the zucchini will release enough liquid for the contents to reach high pressure. Lock the lid and program the Instant Pot to cook for 35 minutes under high pressure.
  6. When the sauce is done cooking, you can wait for the pressure to release naturally or you can manually vent it if you’re impatient.
  7. The zucchini and onions should be fork-tender and easily mashed with a spatula to form a chunky sauce.
  8. Taste the sauce and adjust the seasoning with additional Magic Mushroom Powder, salt, or freshly ground pepper. Stir in the juice from half a lemon and taste it again. (Always, always, ALWAYS taste your food and season accordingly!)
  9. When the sauce is ready, grab a spiralizer to prepare some zucchini noodles (or grab some ready-to-go spiralized veggies at the store). If I’m serving this sauce on zoodles, I drop the raw spiralized zucchini straight into the pot and toss ’em around until the hot sauce softens the zoodles to my liking.
  10. Top with your favorite herbs and dig in! This sauce freezes really well so make a batch whenever your vegetable crisper is overflowing with zucchini!

Notes

Slow cooker instructions:

If you want to cook this in a slow cooker, sauté the onions and sausage before adding them with the rest of the ingredients into the slow cooker. Program your Crockpot to cook on low for 6 to 8 hours or until the zucchini is super tender.

Stove-top instructions:

Follow my directions below but cook the zucchini bolognese in a large saucepan or Dutch oven over medium heat on the stovetop. Once all the ingredients are in the pot, bump up the heat to bring everything to a boil. Then, decrease the heat to maintain a simmer and cover and cook on low heat for 3 to 4 hours or until the zucchini falls apart. Stir occasionally, and add a splash of broth or water if the pot looks dry while it’s cooking.
