I firmly believe Brussels sprouts deserve better than being boiled into submission. Roasting is how I make them every single time.
The trick is giving them plenty of time in a hot oven with the cut sides directly against the sheet pan. Leave them alone and let those edges get good and brown. That little bit of patience is what makes these Oven-Roasted Brussels Sprouts worth making.
Why You'll Love These Oven-Roasted Brussels Sprouts
- High-heat roasting: Gives the Brussels sprouts browned, caramelized edges instead of leaving them soft or soggy.
- Cut-side down: More contact with the hot sheet pan means better browning.
- Garlic + Parmesan: Adds plenty of savory flavor with simple ingredients.
- Fresh lemon: Brightens everything up right before serving.
- Hands-off: Get them on the sheet pan and let the oven do the work.
What You'll Need & Why
- Brussels sprouts – trimmed, halved, and ready for maximum crispiness
- Garlic – roughly chopped so it roasts without burning
- Parmesan cheese – grated; melts into golden, salty, crispy bits
- Extra virgin olive oil – helps the sprouts caramelize instead of steam
- Lemon (juice + zest) – brightens the richness and makes the flavors pop
- Kosher salt & fresh cracked black pepper – essential for balance and depth
The Recipe Rundown
- Prep: Wash, dry, trim, and halve the Brussels sprouts.
- Season: Toss with olive oil, garlic, Parmesan, salt, and pepper.
- Arrange: Place cut-side down in a single layer on a sheet pan.
- Roast: Cook at 425°F until tender with deeply browned, crispy edges.
- Finish: Toss with fresh lemon zest and juice and serve.
Swaps & Variations
These Oven-Roasted Brussels Sprouts are easy to change up with a few simple additions.
- Make them spicy: Add red pepper flakes or finish with a little chili crisp.
- Swap the cheese: Pecorino works beautifully in place of Parmesan, or finish with crumbled feta after roasting.
- Add balsamic: Finish with a drizzle of balsamic vinegar or glaze for a little sweetness and tang.
- Add bacon: Toss in cooked, crumbled bacon before serving.
- Add a little sweetness: A drizzle of honey or maple syrup pairs well with the browned Brussels sprouts and Parmesan.
- Add some crunch: Finish with toasted pecans or sliced almonds.
Tips for The Best Oven-Roasted Brussels Sprouts
A few simple things will help your Brussels sprouts brown and crisp instead of steaming on the sheet pan.
- Dry them well: Any water left on the Brussels sprouts creates steam and works against browning.
- Give them room: Spread the sprouts in a single layer without crowding the pan.
- Roast cut-side down: Direct contact with the sheet pan gives the flat sides the best caramelization.
- Leave them alone: There’s no need to constantly toss or flip them while they roast.
- Size affects roasting time: Smaller Brussels sprouts may be ready closer to 20 minutes, while larger sprouts can need the full 30 minutes to become tender and deeply browned.
- Roughly chop the garlic: Slightly larger pieces are less likely to burn during the high-heat roast.
- Use freshly grated Parmesan: It melts and browns much better than pre-shredded cheese.
