⭐ Ingredients You Need

Brussels Sprouts

Choose fresh sprouts that are bright green, compact, and heavy for their size.

Olive Oil

Helps crisp and caramelize the sprouts.

Garlic

Fresh minced garlic adds deep savory aroma.

Parmesan Cheese

Freshly grated melts beautifully and adds salty richness.

Salt & Pepper

Basic seasoning that brings all the flavors forward.

Optional Add-ins

Chili flakes, lemon zest, smoked paprika, or balsamic glaze.

⭐ How to Make Garlic Parmesan Roasted Brussels Sprouts

1. Prep the Brussels Sprouts

Trim the ends and remove any loose or yellow leaves. Cut sprouts in half to help them roast evenly.

2. Coat with Seasonings

Toss sprouts with olive oil, garlic, salt, pepper, and half the parmesan (save the rest for after roasting).

3. Roast at High Heat

Spread the sprouts cut-side down on a baking sheet and roast at 425°F (220°C). This ensures crispy edges and caramelization.

4. Add More Parmesan

Once golden and crisp, toss the sprouts with the remaining parmesan for extra cheesy flavor.

5. Serve Hot

Add chili flakes, lemon zest, or black pepper if you like.

This method makes sprouts crispy on the outside and tender inside — the perfect texture combo.
