Introduction to a Classic: Roasted Brussels Sprouts and Bacon

Since its debut on this blog back in 2010, our smoky roasted Brussels sprouts and bacon recipe has consistently been a fan favorite, captivating palates with its simple yet profound flavors. It’s a testament to how humble ingredients, when combined thoughtfully, can create a truly unforgettable dish. For many, including myself during childhood, Brussels sprouts were often seen as a culinary challenge, a vegetable to be politely avoided. However, this recipe transforms those tiny green globes into a craveable delight that even the most skeptical eaters will adore. It’s not just a dish; it’s an experience that proves Brussels sprouts can be the star of any table.

What makes this particular combination so special? It’s the harmonious interplay of textures and tastes: the earthy, slightly bitter notes of perfectly caramelized Brussels sprouts are beautifully complemented by the salty, smoky crunch of bacon. This pairing creates a symphony of flavor that is both comforting and sophisticated, making it an ideal side for any occasion, from a casual weeknight dinner to an elegant holiday feast. Furthermore, its natural compatibility with Whole30, Keto, and Paleo dietary guidelines means it’s a healthy indulgence everyone can enjoy without compromise.

The Irresistible Pairing: Brussels Sprouts and Bacon

It was only in adulthood that I truly grasped the magic that unfolds when the mild, nutty bitterness of Brussels sprouts meets the savory allure of smoky pork. This revelation first occurred at the now-defunct Gordon’s House of Fine Eats in San Francisco, where a warm Brussels sprouts salad with bacon and eggs permanently altered my perception. That dish served as the direct inspiration for the Cavolini Al Forno recipe featured in my first cookbook.

The beauty of roasted Brussels sprouts and bacon lies in its simplicity and the depth of flavor it achieves with minimal effort. Roasting transforms Brussels sprouts, tenderizing their core while crisping their outer leaves to a delightful crunch. When combined with bacon, which renders its fat and infuses every sprout with its irresistible smoky essence, you get a side dish that’s far greater than the sum of its parts. This isn’t just about combining two ingredients; it’s about harnessing their inherent qualities to create a culinary knockout. The saltiness of the bacon enhances the sweetness of the caramelized sprouts, balancing their natural bitterness in a way that’s simply addicting. It truly is a flavor punch to the face, in the best possible way!

Air Fryer vs. Oven: Choosing Your Cooking Method

One of the most frequently asked questions about this recipe is: “Can you make it in an air fryer?” The answer is a resounding yes! The air fryer is an excellent tool for achieving beautifully browned Brussels sprouts and crispy bacon bits, often cutting the cooking time significantly. The intense, circulating heat of an air fryer mimics deep-frying with far less oil, resulting in an exceptionally crispy exterior for both the sprouts and the bacon.

However, while the air fryer offers speed and superior crispiness, it does come with a primary disadvantage: most models have a smaller cooking capacity. This means that for a recipe serving multiple people, you will likely need to cook in two or more batches to avoid overcrowding the basket. Overcrowding can lead to steaming rather than crisping, which defeats the purpose of using an air fryer. We’ll delve into the specific instructions for both oven and air fryer methods below, ensuring you get perfect results regardless of your chosen appliance.

Key Ingredients for Perfection

Achieving the perfect roasted Brussels sprouts and bacon relies on a few high-quality, simple ingredients. Here’s what you’ll need and some tips for selecting them:

• Brussels Sprouts: Look for firm, bright green sprouts with tightly packed leaves. Avoid any with yellowing leaves or soft spots. Freshness makes a huge difference in flavor and texture.
• Melted Ghee, Avocado Oil, Extra Virgin Olive Oil, or Fat of Choice: The choice of fat impacts the final flavor and crispiness. Ghee adds a buttery richness, while avocado oil is neutral and has a high smoke point. Extra virgin olive oil is also a great option, adding a subtle fruitiness.
• Diamond Crystal Kosher Salt: This type of salt is preferred by many chefs for its clean taste and coarser texture, which allows for more even seasoning. If using table salt, use about half the amount.
• Freshly Ground Black Pepper: Freshly ground pepper offers a more vibrant and aromatic kick compared to pre-ground pepper.
• Bacon: The star of the show! Choose good quality bacon for the best flavor. For Whole30 compatibility, ensure you select sugar-free bacon. Thick-cut bacon works wonderfully for creating substantial, crispy bits.
• Aged Balsamic Vinegar: A drizzle of aged balsamic vinegar at the end adds a touch of sweetness, acidity, and complexity that brightens the entire dish, cutting through the richness of the bacon and complementing the sprouts.

With these foundational ingredients, you’re well on your way to creating a truly spectacular side dish that’s both flavorful and healthful.

Step-by-Step Guide to Roasting Brussels Sprouts and Bacon

Whether you choose the oven or the air fryer, the preparation steps for your Brussels sprouts and bacon remain largely the same, focusing on freshness and proper seasoning. Follow these instructions for a perfect batch every time.

Preparation:

1. Preheat Your Appliance: If using an oven, preheat it to 400°F (200°C) with a rack in the middle. If using an air fryer, no preheating is typically needed, but you can set it to 400°F (200°C) if your model recommends it.
2. Prepare the Brussels Sprouts: Trim the tough, woody ends from the Brussels sprouts. Peel away any old, yellowed, or loose outer leaves. Don’t discard these! They can be saved in a container in the fridge to make delicious Brussels Sprouts Chips later.
3. Halve the Sprouts: Cut each Brussels sprout in half lengthwise. This ensures more surface area for caramelization and even cooking.



4. Season Generously: In a large bowl, toss the halved Brussels sprouts with your chosen melted fat (ghee, avocado oil, or extra virgin olive oil), a generous pinch of Diamond Crystal kosher salt, and freshly ground black pepper. Ensure every sprout is lightly coated.



5. Dice the Bacon: Dice your bacon slices into small, manageable pieces. These will become wonderfully crispy and infuse their smoky flavor into the sprouts.

Oven Roasting Instructions

Roasting in the oven is a classic method that yields tender-crisp sprouts and wonderfully browned bacon. It’s perfect for larger batches.

1. Arrange on Baking Sheet: Dump the seasoned Brussels sprouts onto a foil- or parchment-lined rimmed baking sheet. Spread them out into a single layer. This is crucial for crispiness; avoid overcrowding, which can lead to steaming.
2. Add Bacon: Evenly sprinkle the diced bacon over the Brussels sprouts.



3. Roast to Perfection: Pop the tray into the preheated oven. The sprouts typically take about 30 to 35 minutes to roast. For even cooking and maximum crispiness, set a timer for 10-minute intervals to rotate the pan and flip the sprouts and bacon. This ensures consistent browning on all sides.



4. Check for Doneness: The dish is ready when the Brussels sprouts are tender inside, beautifully caramelized and browned on the outside, and the bacon bits are wonderfully crispy.

Air Frying for Extra Crispiness

For those who love an extra-crispy texture and faster cooking, the air fryer is your friend. Remember to work in batches!

1. Load the Air Fryer Basket: Place about half of the seasoned Brussels sprouts and half of the diced bacon into your air fryer basket. Ensure they are in a single layer to allow air to circulate freely.
2. Air Fry: Air fry at 400°F (200°C) for 12 to 15 minutes. Make sure to toss the contents of the basket at the halfway point (around 6-7 minutes) to ensure even cooking and browning.
3. Check for Doneness: The dish is done when the sprouts and bacon are deeply browned and have achieved a delightful crispiness.



4. Repeat if Necessary: Repeat the same steps with the remaining seasoned Brussels sprouts and bacon until all batches are cooked to perfection.

Finishing and Serving

Once your Brussels sprouts and bacon are cooked using either method, a final touch elevates the flavor profile:

Taste the roasted or air-fried Brussels sprouts and adjust the seasoning if needed. A final sprinkle of salt or pepper can make all the difference. Then, drizzle some aged balsamic vinegar generously over the finished dish. The tangy sweetness of the balsamic vinegar provides a perfect counterpoint to the rich, smoky flavors. Serve immediately and dig in!

Expert Tips and Variations

While this recipe is fantastic as is, here are some tips to perfect it and ideas for variations to suit your taste:

• Don’t Overcrowd: This is the most crucial tip for both oven and air fryer methods. Overcrowding leads to steaming, not roasting, resulting in soggy sprouts instead of crispy ones. Use multiple baking sheets or air fryer batches if necessary.
• Even Sizing: Try to cut your Brussels sprouts into similar sizes so they cook evenly.
• High Heat is Key: Roasting at 400°F ensures the sprouts caramelize beautifully and become tender without turning mushy.
• Add Aromatics: For an extra layer of flavor, toss in a few cloves of minced garlic or thinly sliced shallots with the Brussels sprouts before roasting.
• Herbacious Twist: Fresh herbs like rosemary or thyme, finely chopped, can be added along with the bacon for an aromatic finish.
• Spicy Kick: A pinch of red pepper flakes can introduce a subtle heat to the dish.
• Cheesy Indulgence (Not Whole30/Keto): If not adhering to Whole30 or Keto, a sprinkle of grated Parmesan cheese during the last 5 minutes of roasting adds a delicious salty, umami layer.
• Alternative Vegetables: This versatile technique works wonderfully with other vegetables. You can easily substitute Brussels sprouts with cauliflower florets or broccoli florets, following the same preparation and cooking guidelines for an equally delicious side.

Storing and Reheating Leftovers

Should you be lucky enough to have any leftovers of this delectable dish, they can be easily stored and repurposed for future meals. Place any remaining roasted Brussels sprouts and bacon in an airtight container and refrigerate for up to four days.

When it comes to reheating, for best results, avoid the microwave if you want to retain some crispiness. Instead, gently reheat the leftovers in a skillet over medium heat until warmed through and slightly re-crisped. Alternatively, you can pop them back into a preheated oven at 350°F (175°C) or an air fryer for a few minutes until hot and crisp again. These reheated leftovers make an excellent base for a quick and satisfying scramble, a hearty frittata, or simply topped with a perfectly fried egg for a delicious breakfast or light lunch.
