Ingredients You’ll Need
Simple, wholesome ingredients are all you need to whip up this showstopper dish. Each component plays a vital role, whether it’s adding vibrant color, a punch of flavor, or creating that irresistible crispy texture.
- 1 1/2 pounds Brussels sprouts, trimmed and halved: Fresh and firm Brussels sprouts ensure a tender yet crisp result when roasted.
- 3 tablespoons olive oil: This coats the sprouts for even roasting and adds a smooth, fruity base flavor.
- 3 garlic cloves, minced: Garlic brings a fragrant, savory aroma that infuses every bite.
- 1/2 teaspoon salt: Essential for enhancing the natural earthiness of the Brussels sprouts.
- 1/4 teaspoon black pepper: Adds a subtle warmth and balances the garlic’s sharpness.
- 1/2 teaspoon crushed red pepper flakes (optional): A touch of heat that complements the nutty Parmesan beautifully.
- 1/2 cup grated Parmesan cheese: The star ingredient that melts slightly on the hot sprouts, lending salty richness and depth.
- Fresh parsley, chopped, for garnish (optional): A sprinkle of bright green that livens up the dish visually and adds fresh herbal notes.
How to Make Garlic Parmesan Roasted Brussels Sprouts Recipe
Step 1: Prep Your Oven and Sprouts
Start by preheating your oven to 400°F (200°C) and lining a large baking sheet with parchment paper. This makes clean-up a breeze and prevents sticking. Meanwhile, trim the Brussels sprouts by cutting off the stem ends and removing any yellow outer leaves. Halve them lengthwise to expose more surface area to the heat, which is key to achieving that coveted caramelized crispiness.
Step 2: Season and Toss
In a spacious bowl, combine your halved Brussels sprouts with olive oil, minced garlic, salt, black pepper, and the optional crushed red pepper flakes if you like a bit of spice. Toss everything gently but thoroughly to make sure every sprout has a nice, even coating of seasoning. This step ensures maximum flavor on every bite.
Step 3: Roast to Perfection
Arrange the Brussels sprouts in a single layer on your prepared baking sheet, placing them cut side down. This directs the heat to the inner surfaces, helping them caramelize beautifully. Roast for 20 to 25 minutes, flipping the sprouts halfway through cooking for even browning. You’ll know they’re ready when their edges turn golden and slightly crispy while the centers stay tender.
Step 4: Add the Parmesan Magic
Once out of the oven, immediately sprinkle the hot Brussels sprouts with grated Parmesan cheese. The residual heat melts the cheese slightly, coating the sprouts in a luscious, savory blanket. Toss gently to combine the cheese evenly, and prepare to wow everyone with this savory transformation.
Step 5: Garnish and Serve
For an extra touch of color and freshness, sprinkle chopped fresh parsley over the top. This final flourish brightens the look and adds a subtle herbal contrast to the rich flavors.

Side Dishes
This Garlic Parmesan Roasted Brussels Sprouts Recipe pairs beautifully with a wide variety of mains. Think juicy roasted chicken, seared steak, or even your favorite pasta dish. Its bold flavors and satisfying texture complement and balance richer proteins and starches effortlessly.
Creative Ways to Present
Try serving these roasted sprouts tossed into a warm grain bowl with quinoa or farro, scattered on top of a fresh salad for crunch, or even folded into a savory tart or flatbread for a unique twist. Their versatility makes them a fabulous ingredient to showcase beyond just a side plate.
Make Ahead and Storage
Storing Leftovers
Keep any leftover Garlic Parmesan Roasted Brussels Sprouts in an airtight container in the refrigerator. They will stay fresh for up to 3 days and can be quickly refreshed before serving.
Freezing
While roasted Brussels sprouts are best enjoyed fresh to preserve their crisp texture, you can freeze leftovers by cooling them completely and storing in a freezer-safe bag or container for up to 2 months. Keep in mind reheated frozen sprouts might be softer.
Reheating
To bring leftover Brussels sprouts back to life, reheat them in a skillet over medium heat or in a hot oven for a few minutes until warmed through and crisp again. Avoid microwaving if possible, as it can make them soggy.
FAQs
Can I use frozen Brussels sprouts for this recipe?
Fresh Brussels sprouts are best because they roast up crispier and caramelize better. Frozen can be used, but make sure to thaw and dry them thoroughly; otherwise, they may steam rather than roast.
How do I make this recipe vegan?
Simply omit the Parmesan cheese or substitute it with a vegan cheese alternative or nutritional yeast for that cheesy flavor without dairy.
Why are some of my Brussels sprouts mushy after roasting?
Overcrowding the pan or uneven cutting can cause steaming instead of roasting. Spread the sprouts out in a single layer and make sure they are similarly sized for the best texture.
Can I add other seasonings to the Garlic Parmesan Roasted Brussels Sprouts Recipe?
Absolutely! Smoked paprika, lemon zest, or a dash of balsamic vinegar can add exciting flavor layers. Just be careful not to overpower the garlic and Parmesan foundation.
What is the best way to get extra crispy Brussels sprouts?
Use high heat, avoid overcrowding, roast cut side down, and flip once during cooking. These tips help create maximum caramelization and crisp edges.
