The charm of this Garlic Parmesan Roasted Brussels Sprouts Recipe lies in its straightforward ingredients. Each component plays a crucial role, whether it’s building layers of flavor, adding crisp texture, or bringing vibrant color to your dish.
- 1 1/2 pounds Brussels sprouts (trimmed and halved): Fresh sprouts provide a tender center with crispy edges when roasted.
- 3 tablespoons olive oil: Helps the sprouts caramelize perfectly and adds a smooth richness.
- 4 cloves garlic (minced): Infuses a punch of savory aroma that enhances every bite.
- 1/2 teaspoon salt: Balances the flavors and brings out the natural sweetness of the sprouts.
- 1/4 teaspoon black pepper: Adds a subtle heat to round out the seasoning.
- 1/2 teaspoon crushed red pepper flakes (optional): For those who love a little spice, this elevates the flavor complexity.
- 1/3 cup grated Parmesan cheese: Melts over the sprouts for a crispy, nutty, and irresistible topping.
- 1 tablespoon lemon juice (optional): Adds a fresh, zesty brightness that cuts through the richness.
- Chopped fresh parsley for garnish (optional): Brings a pop of color and a subtle herbaceous note.
How to Make Garlic Parmesan Roasted Brussels Sprouts Recipe
Step 1: Prep Your Brussels Sprouts
Start by trimming the bottoms off the Brussels sprouts and slicing them in half. This ensures they cook evenly and get those beautiful caramelized edges that everyone loves. The halving also helps the garlic and seasoning cling to each piece, maximizing flavor.
Step 2: Toss with Olive Oil and Seasonings
In a large mixing bowl, combine the halved Brussels sprouts with olive oil, minced garlic, salt, black pepper, and crushed red pepper flakes if you like a bit of heat. Make sure every sprout is well coated—this step is key to achieving that crispy, roasted texture.
Step 3: Roast the Brussels Sprouts
Spread the sprouts out in a single layer on a baking sheet, placing them cut side down. This technique encourages browning and that irresistible crunch. Pop them in a preheated 400°F oven and roast for 20 to 25 minutes, stirring once halfway through to ensure even cooking and browning.
Step 4: Add Parmesan and Finish Roasting
Once golden and tender, pull the baking sheet out of the oven and sprinkle the grated Parmesan cheese evenly over the sprouts. Return them to the oven for an additional 3 to 5 minutes until the cheese melts and crisps up just perfectly.
Step 5: Add Final Touches
Optional but highly recommended — drizzle fresh lemon juice over the hot sprouts and sprinkle with chopped parsley. These brighten and freshen the flavors, making this Garlic Parmesan Roasted Brussels Sprouts Recipe truly unforgettable.
How to Serve Garlic Parmesan Roasted Brussels Sprouts Recipe

Garnishes
Fresh chopped parsley is the classic final touch, adding vibrant green color and a fresh herbaceous note that contrasts beautifully with the rich cheese and roasted flavors. For a twist, try crispy bacon bits or toasted pine nuts for texture and added depth.
Side Dishes
This recipe shines as a side for roasted chicken, grilled steak, or pan-seared salmon. It also pairs wonderfully with creamy mashed potatoes or a simple grain like quinoa or farro, balancing heartiness and freshness on your plate.
Creative Ways to Present
For a party, serve these sprouts piled high on a rustic wooden platter sprinkled with extra Parmesan and parsley. Or toss them into a warm salad with toasted nuts and dried cranberries for a festive twist. You could even stuff them into a crusty sandwich for a crunchy, cheesy veggie surprise.
Make Ahead and Storage
Storing Leftovers
Store leftover Garlic Parmesan Roasted Brussels Sprouts in an airtight container in the refrigerator for up to 3 days. They remain tasty and can be enjoyed cold or reheated.
Freezing
While roasting brings out the best texture, you can freeze cooked Brussels sprouts. Spread them out on a baking sheet to freeze individually before transferring to a freezer bag. Use within 1 month for best results, keeping in mind the texture may soften slightly after thawing.
Reheating
Reheat leftovers in a skillet over medium heat or in a 375°F oven to revive the crispiness. Avoid microwaving as it tends to make them soggy.
FAQs
Can I use frozen Brussels sprouts for this recipe?
Frozen can work in a pinch, but fresh Brussels sprouts roast better and develop that signature crispy exterior. If using frozen, make sure to thaw and pat dry to avoid sogginess.
How do I make this recipe vegan?
Simply omit the Parmesan cheese or substitute it with a vegan cheese alternative or nutritional yeast for a cheesy flavor without dairy.
Can I add other seasonings or herbs?
Absolutely! Fresh rosemary, thyme, or smoked paprika can add unique twists. Just remember to keep the garlic and Parmesan core that make this recipe shine.
What is the best way to ensure crispiness?
Don’t overcrowd the baking sheet; give each sprout room to roast and brown. Also, placing them cut side down on the pan is crucial for that perfect crunch.
Is there a way to reduce the garlic flavor intensity?
If you are sensitive to garlic, you can reduce the amount or swap raw garlic for roasted garlic for a milder, sweeter taste.
