Ingredients for Garlic Parmesan Roasted Brussels Sprouts

• Salt
• Black pepper

How to Prepare Brussels Sprouts for Roasting

Preparation matters just as much as seasoning when it comes to crispy Brussels sprouts.

1. Trim the stems
   Remove the dry ends from each sprout.
2. Remove loose outer leaves
   These may burn during roasting.
3. Cut evenly
   Slice sprouts in half lengthwise. Large sprouts can be quartered so everything cooks evenly.
4. Dry thoroughly
   Moisture prevents crisping. Pat dry after washing.

Instructions: Garlic Parmesan Roasted Brussels Sprouts

1. Preheat your oven to 425°F (220°C). Line a large baking sheet with parchment paper or lightly grease it.
2. Place the trimmed and halved Brussels sprouts in a large mixing bowl.
3. Drizzle with olive oil and toss until all sprouts are evenly coated.
4. Add minced garlic, salt, and black pepper. Toss again to distribute evenly.
5. Spread the Brussels sprouts in a single layer on the baking sheet, cut-side down for maximum caramelization.
6. Roast for 20 minutes, then flip the sprouts and continue roasting for another 10–15 minutes until golden brown and crispy at the edges.
7. Remove from the oven and immediately sprinkle with grated Parmesan cheese.
8. Return to the oven for 3–5 minutes, just until the cheese melts and lightly crisps.
9. Finish with optional red pepper flakes, lemon zest, or chopped parsley before serving.

Secrets to Extra Crispy Brussels Sprouts

If you want restaurant-level crispiness, keep these tips in mind:

• Don’t overcrowd the pan — use two pans if needed
• High heat is essential — 425°F or higher
• Cut-side down roasting creates deep browning
• Finely grated Parmesan melts and crisps better than shredded
• Add cheese at the end to avoid burning

Flavor Variations to Try

This recipe is easy to customize:

• Spicy Parmesan Brussels Sprouts: Add chili flakes or cayenne
• Lemon Garlic Parmesan: Finish with lemon juice and zest
• Balsamic Parmesan: Drizzle with balsamic glaze after roasting
• Cheesy Upgrade: Add pecorino romano or asiago
• Vegan Version: Use nutritional yeast instead of Parmesan

Serving Suggestions

Garlic Parmesan Roasted Brussels Sprouts pair beautifully with:

• Roast chicken or turkey
• Steak or grilled salmon

They’re also delicious straight from the pan as a crispy snack.

Storage and Reheating Tips

• Storage: Keep leftovers in an airtight container for up to 3 days
• Reheating: Reheat in the oven or air fryer to restore crispiness
• Avoid microwaving if possible — it softens the texture

Fun Fact: Why Brussels Sprouts Taste Better Now

Modern Brussels sprouts are less bitter than they used to be. Selective breeding over the years has reduced sulfur compounds, making them naturally sweeter — especially when roasted.
