Roasted Brussels Sprouts with Bacon

Method

1. Render the bacon in a skillet over medium heat for 6-8 minutes until crispy. Remove the bacon pieces and set aside. Reserve the rendered bacon fat — you'll use it to roast the sprouts.

2. Prep the sprouts by trimming the stem ends and cutting each sprout in half through the core. Remove any loose or yellowed outer leaves. Toss the halved sprouts with the reserved bacon fat, olive oil, garlic, salt, and pepper in a large bowl.

3. Arrange cut-side down on a rimmed sheet pan in a single layer with space between each sprout. This is the most important step — the flat cut surface needs direct contact with the hot pan to caramelize. Don't pile them up.

4. Roast at 425°F for 20-25 minutes without stirring for the first 15 minutes. The cut sides should develop a deep golden-brown caramelization. Toss once at the 15-minute mark, then continue roasting until the edges are crispy and the centers are tender.

5. Finish by transferring the hot sprouts to a serving bowl. Toss with the crispy bacon pieces, drizzle with balsamic glaze, and shower with freshly grated Parmesan. Add red pepper flakes if you want a little heat.

6. Serve immediately while the sprouts are still crispy. They soften as they cool. This is the side dish that converts brussels sprout haters — the combination of caramelized sweetness, smoky bacon, tangy balsamic, and salty Parmesan hits every flavor note.

Equipment

• Rimmed sheet pan Recommended: Nordic Ware Natural Aluminum Half Sheet Pan
• Large skillet (for bacon) Recommended: Joyce Chen 14-Inch Carbon Steel Wok

Chef Notes

• The most important thing: Cut the brussels sprouts in half and place them cut-side down on the sheet pan. The flat surface maximizes contact with the hot pan, creating deep caramelization. Round side down = steamed sprouts. Flat side down = crispy, golden sprouts.
• Don't crowd the pan. Brussels sprouts release moisture as they roast — if they're packed too tightly, they steam instead of caramelizing. Use two sheet pans if needed. Space between each sprout is essential.
• Render the bacon first and use the bacon fat for roasting. The rendered fat adds smoky flavor to every sprout. Toss the sprouts in bacon fat instead of (or in addition to) olive oil.
• High heat (425°F) is non-negotiable. Lower temperatures won't caramelize the cut surfaces — you'll get soft, pale sprouts instead of crispy, golden ones.
• Add the balsamic glaze after roasting, not before. Sugar in balsamic burns at high oven temperatures. Drizzle it on the hot sprouts right out of the oven.

Common Substitutions

Ingredient	Substitution	Notes
Bacon	Pancetta or prosciutto	Pancetta is unsmoked; prosciutto crisps in 3 min in the oven
Balsamic glaze	Honey + 1 tsp balsamic vinegar	Similar sweet-tangy effect
Parmesan	Pecorino Romano	Sharper and saltier — use slightly less
Brussels sprouts	Broccoli florets	Same roasting technique — cut flat sides for maximum caramelization
Oven roasting	Air fryer at 400°F, 12-15 min	Shake basket halfway — excellent crispiness

What You're Practicing

High-heat roasting with maximum surface contact is the technique that makes vegetables taste incredible. The Maillard reaction on the cut surfaces creates hundreds of flavor compounds — sweetness, nuttiness, and depth that raw or steamed vegetables don't have. This same technique applies to roasted broccoli, cauliflower, carrots, and any vegetable you want to caramelize. Visit Techniques for more on roasting vegetables.

Using rendered bacon fat as a cooking medium teaches you about flavored fats. The same principle drives cooking with duck fat, schmaltz (chicken fat), and lard — each fat carries its own flavor into the food. Understanding that cooking fat is a seasoning, not just a cooking medium, elevates every dish you make.
