Ingredients for Garlic Parmesan Roasted Brussels Sprouts

Use fresh, firm Brussels sprouts for the best texture and flavor. Avoid sprouts that are yellowing or overly soft.

Ingredients:

Fresh Brussels sprouts, trimmed and halved
Olive oil
Fresh garlic, minced
Salt
Black pepper
Grated Parmesan cheese (freshly grated preferred)
Optional: crushed red pepper flakes
Optional garnish: chopped parsley or lemon zest

Simple ingredients, big payoff. The key is balance—enough oil to encourage browning, enough garlic to infuse flavor without burning, and enough Parmesan to coat the sprouts without overwhelming them.

Instructions: How to Make Garlic Parmesan Roasted Brussels Sprouts

Preheat the oven to 425°F (220°C). A hot oven is essential for achieving crispy, caramelized Brussels sprouts.
Prepare the Brussels sprouts by trimming off the woody ends and slicing them in half lengthwise. If some sprouts are very large, quarter them so everything cooks evenly.
Dry thoroughly. After washing, pat the Brussels sprouts completely dry. Moisture prevents browning.
Toss with oil and seasonings. Place the sprouts in a large bowl and toss with olive oil, minced garlic, salt, and black pepper until evenly coated.
Arrange on a baking sheet. Spread the Brussels sprouts cut-side down in a single layer on a rimmed baking sheet. Avoid overcrowding.
Roast. Place in the oven and roast for 20–25 minutes, flipping once halfway through, until deeply golden and crispy at the edges.
Add Parmesan. Remove from the oven, sprinkle generously with grated Parmesan, and return to the oven for 3–5 minutes until the cheese melts and lightly crisps.
Finish and serve. Taste and adjust seasoning. Add red pepper flakes, parsley, or lemon zest if desired. Serve immediately for best texture.

Pro Tips for Extra Crispy Brussels Sprouts

High heat is non-negotiable. Lower temperatures steam the sprouts instead of roasting them.
Cut-side down matters. This maximizes surface contact with the pan and promotes browning.
Don’t overcrowd the pan. Use two pans if needed. Crowding traps steam.
Fresh Parmesan works best. Pre-shredded cheese doesn’t melt or crisp as well.
Add garlic carefully. Mixing garlic with oil helps prevent burning.

Flavor Variations to Try

One of the best things about garlic Parmesan roasted Brussels sprouts is how customizable they are.

Lemon Parmesan Brussels Sprouts: Add fresh lemon zest and a squeeze of juice before serving.
Balsamic Parmesan: Drizzle with balsamic glaze after roasting for sweet-tangy contrast.
Spicy Garlic Brussels Sprouts: Add chili flakes or a pinch of cayenne.
Cheesy Upgrade: Mix Parmesan with Pecorino Romano for deeper flavor.
Vegan Version: Use nutritional yeast instead of Parmesan for a dairy-free option.

Serving Suggestions

Garlic Parmesan roasted Brussels sprouts pair beautifully with a wide range of dishes. Serve them alongside roasted chicken, grilled steak, baked salmon, or pork tenderloin. They’re also excellent with pasta, risotto, or grain bowls.

Leftovers (if you have any) can be reheated in the oven or air fryer to restore crispness. Avoid microwaving, which softens the sprouts.
