Tools
Useful tools for this sheet-pan recipe.
- Large mixing bowl
- Rimmed non-stick baking sheet
Quick Overview
This is a short summary—see the recipe card at the end for exact measurements and full instructions.
Preheat oven to 400°F (see recipe card).
Trim and halve the Brussels sprouts, then pat them dry and place them in a large bowl.
In a small bowl, mix the Italian seasoning, minced garlic, salt, pepper, and olive oil. Toss the sauce with the sprouts until evenly coated.
Add the Parmesan and toss once more so the cheese clings to the sprouts.
Tip: For less cheese on the pan and more on the sprouts, sprinkle Parmesan by hand after spreading the sprouts on the sheet.
Spread the sprouts in a single layer on a rimmed baking sheet and roast.
Bake 15 minutes, then remove and toss, scraping any browned Parmesan from the pan so it gets redistributed. Return to the oven for another 5 minutes, toss again, and bake an additional 0–5 minutes if you want them extra crispy—watch closely to avoid burning the cheese.
Once they’re golden and crisp to your liking, plate and serve immediately.
Tips & Tricks
- For extra crispiness, roast the sprouts alone for 10 minutes before adding Parmesan.
- To keep most cheese on the sprouts instead of the pan, sprinkle Parmesan by hand after arranging them on the sheet.
- Choose firm, unblemished sprouts for best flavor and texture.
