Why You’ll Love This Recipe
This recipe is perfect because it requires minimal preparation and transforms simple ingredients into a gourmet delight. The roasting process caramelizes the Brussels sprouts, giving them a natural sweetness, while the Parmesan adds a savory crunch. It’s a fantastic way to introduce more vegetables to your meals without sacrificing flavor.
Ingredients Notes
The key to great Brussels sprouts is in the selection. Look for fresh, bright green sprouts without any yellowing leaves. You can substitute Pecorino cheese if you’re out of Parmesan. For an extra touch of flavor, add a squeeze of lemon juice after roasting.
Recipe Steps
Step 1
Preheat your oven to 400°F (200°C). Line a baking sheet with parchment paper to prevent sticking and for easy cleanup.
Step 2
Trim the ends off the Brussels sprouts and remove any outer leaves that are discolored. Cut them in half for even roasting.
Step 3
In a large bowl, toss the sprouts with olive oil, salt, and pepper. Spread them out evenly on the baking sheet in a single layer.

Step 4
Sprinkle a generous amount of grated Parmesan cheese over the sprouts, ensuring each piece is coated.
Step 5
Roast for 20-25 minutes, or until the sprouts are tender on the inside and crispy on the outside. Serve immediately for the best texture.
Storage Options
Leftover Brussels sprouts can be stored in an airtight container in the refrigerator for up to 3 days. Reheat them in the oven at a low temperature to regain their crispy texture. Alternatively, freeze them, but note they may lose some crispiness when reheated.
Variations & Substitutions
To mix things up, try adding a sprinkle of chili flakes for heat or a handful of toasted nuts for extra crunch. For a vegan version, use nutritional yeast instead of Parmesan for that cheesy flavor.
Serving Suggestions
These sprouts make a perfect side dish for any roast dinner. They’re also great for holiday gatherings or served cold in a salad for a light lunch. Pair with a crisp white wine to enhance the flavors.
