Oven Roasted Brussels Sprouts (Garlic Parmesan Perfection for Crispy Edges)

I’ll be honest with you—I didn’t always love Brussels sprouts. As a kid, I avoided them on my plate because they were either boiled or mushy, and no one really sold me on their flavor. But the first time I had oven roasted Brussels sprouts, everything changed.

Crispy edges. A little char. Garlic and Parmesan clinging to every bite. Suddenly, these little green gems became one of my favorite vegetables—and now they’re on repeat in my kitchen.

This recipe is family-approved, simple enough for busy weeknights, and fancy enough for a holiday spread. If you’ve struggled to get your kids or picky eaters to try Brussels sprouts, roasting them is the way to go. Trust me, once you try them this way, there’s no going back.

Why You’ll Love These Oven Roasted Brussels Sprouts

• Crispy and golden – no soggy sprouts here.

• Family-friendly – even picky eaters warm up to them.
• Quick prep – just a few minutes of chopping and tossing.

Ingredients You’ll Need

Here’s what you’ll need for this recipe. Nothing complicated—just pantry staples and fresh Brussels sprouts.

• 2 pounds Brussels sprouts, cleaned, trimmed, and halved if large
• 2 tablespoons olive oil (use more if needed to coat evenly)
• 1 teaspoon sea salt, plus more to taste
• 1 teaspoon black pepper, plus more to taste
• 6 cloves fresh garlic, minced or smashed
• ¾ cup Parmesan cheese, divided

Tip: Freshly grated Parmesan works best here—it melts beautifully and creates that golden crust we all love.

How to Make Oven Roasted Brussels Sprouts

I love recipes that don’t take a ton of effort but still feel special. These Brussels sprouts are exactly that.

Step 1: Preheat the Oven

Heat your oven to 400°F (200°C). I like to line my sheet pan with parchment paper—it makes cleanup so much easier.

Step 2: Toss Everything Together

In a big mixing bowl, combine the Brussels sprouts, olive oil, garlic, salt, pepper, and ½ cup of Parmesan cheese. Toss until everything is evenly coated.

Step 3: Roast to Crispy Perfection

Spread the sprouts in a single layer on your baking sheet. Don’t overcrowd—this is key to getting those crispy edges. Roast for 15 minutes, flip them over, then roast another 10–15 minutes.

Step 4: Add Cheese and Broil

Sprinkle the remaining Parmesan on top. Switch your oven to broil and cook for another 5 minutes until the cheese melts and turns golden.

My Smashed Brussels Sprouts Method (Extra Crispy!)

Sometimes I go the extra mile and make smashed Brussels sprouts. It’s a little twist that gives you an even crispier texture. Here’s how:

1. Boil whole Brussels sprouts for 5 minutes in salted water.
2. Drain and place them on a cutting board.
3. Use the bottom of a glass to gently smash them flat.
4. Toss with the garlic-Parmesan mixture and roast as usual.

The result? Flat, crispy Brussels sprouts that taste like veggie chips. My kids call them “sprout crisps” and they disappear fast.

Practical Tips for Perfectly Roasted Brussels Sprouts

• Dry them well: Any leftover water from washing will steam the sprouts instead of roasting them.
• Don’t skimp on oil: Olive oil helps crisp them up. If they look dry, add a drizzle more.
• Cut evenly: Halving larger sprouts ensures they roast evenly.
• Use high heat: Roasting at 400°F or higher is key to caramelization.
• Finish with broil: The last 5 minutes under the broiler creates magic.

Variations to Try

• Balsamic glaze: Drizzle over the roasted sprouts for a sweet-savory kick.
• Bacon Brussels sprouts: Add cooked, crumbled bacon for smoky flavor.
• Air fryer Brussels sprouts: Short on time? Toss them in the air fryer at 375°F for 15–20 minutes.
• Lemon zest: Add a sprinkle of lemon zest right before serving for brightness.
• Spicy version: Toss with red pepper flakes or a pinch of cayenne.

Why Brussels Sprouts Deserve a Spot on Your Table

Beyond the crispy, cheesy flavor, let’s not forget the Brussels sprouts benefits. These little veggies are nutritional powerhouses:

• Rich in vitamin C for immune support.
• High in fiber, which helps digestion.
• Packed with antioxidants that reduce inflammation.
• Low in calories but filling, making them a healthy side dish option.

As a mom, I love serving them because I know my family is getting something nutritious, but no one’s complaining about eating their veggies. Win-win.
