Ingredients You’ll Need
These ingredients are wonderfully simple, yet each one plays a crucial role in creating those crispy, flavorful Brussels sprouts you’ll love. The balance of oil, seasoning, cheese, and a hint of garlic ensures every bite is packed with texture and taste.
- 1.5 lbs Brussels sprouts, trimmed and halved: Choosing fresh sprouts and trimming them well ensures even cooking and maximum crispiness.
- 3 tablespoons olive oil: This high-quality oil helps achieve that golden-brown exterior without drying out the sprouts.
- 1/2 teaspoon salt: Just enough to enhance the natural flavor without overpowering it.
- 1/4 teaspoon black pepper: Adds a subtle kick to elevate the taste.
- 1/4 cup grated Parmesan cheese: Parmesan is your secret weapon here, lending a savory depth and crispy finish when melted.
- 2 cloves garlic, minced: Garlic infuses the dish with warmth and aroma, pairing beautifully with the cheese.
- 1 tablespoon balsamic vinegar (optional): For a touch of tangy sweetness that brightens the dish just before serving.
- Pinch of red pepper flakes (optional): Perfect for those who like a little heat to contrast the rich flavors.
How to Make Crispy Parmesan Brussels Sprouts Recipe
Step 1: Preheat and Prepare
Start by preheating your oven to 400°F (200°C) and lining a large baking sheet with parchment paper. This ensures your sprouts roast evenly without sticking, setting the stage for that coveted crispy texture.
Step 2: Toss Brussels Sprouts with Seasoning
In a large bowl, combine the trimmed and halved Brussels sprouts with olive oil, salt, and black pepper. Toss them gently until every piece is coated; this step is essential for even roasting and flavor distribution.
Step 3: Arrange the Sprouts
Spread the Brussels sprouts out in a single layer on the prepared baking sheet, placing them cut side down. This direct contact with the pan helps create a wonderfully caramelized, crispy surface. Avoid overcrowding for the best results—use two sheets if needed.
Step 4: Roast to Golden Perfection
Roast the sprouts for 20 to 25 minutes, flipping them halfway through to encourage even browning. You’ll know they’re ready when they’re tender on the inside and beautifully golden on the outside, with those irresistible crispy edges.
Step 5: Add Garlic and Parmesan Cheese
Remove the baking sheet from the oven, then sprinkle the minced garlic and grated Parmesan cheese evenly over the hot sprouts. Toss everything gently to combine so the cheese clings to every bite.
Step 6: Finish Roasting with Cheese
Pop the sprouts back into the oven for 3 to 5 minutes to melt the Parmesan cheese until it becomes slightly golden and crispy. Keep an eye on them to prevent burning—that melted cheesy layer is pure magic!
Step 7: Add Optional Balsamic and Red Pepper Flakes
After removing the sprouts from the oven, drizzle with balsamic vinegar and sprinkle red pepper flakes if you want to add an extra layer of flavor complexity—this is where personal touches truly shine.
How to Serve Crispy Parmesan Brussels Sprouts Recipe

Garnishes
Adding a final flourish of extra grated Parmesan right before serving amplifies the cheesy goodness and adds an inviting visual appeal. A few fresh parsley leaves can also add a pop of color and a hint of freshness.
Side Dishes
This Crispy Parmesan Brussels Sprouts Recipe pairs beautifully with roasted chicken, grilled steak, or even a hearty pasta. Its crispy, cheesy crunch works as a brilliant foil to rich, savory main dishes and complements a wide array of flavors.
Creative Ways to Present
For a party or special occasion, serve these sprouts in small, individual ramekins topped with a quick drizzle of balsamic glaze. Or sprinkle toasted nuts over the top for an unexpected crunch that takes this dish to the next level.
Make Ahead and Storage
Storing Leftovers
If you’re lucky enough to have leftovers, store them in an airtight container in the fridge. They’ll keep well for up to three days, retaining much of their crispness if cooled properly.
Freezing
Freezing crispy Brussels sprouts is possible but not ideal; the texture can soften upon thawing. If you do freeze, reheat them directly from frozen for best results, but fresh is definitely best for this recipe’s signature crunch.
Reheating
To revive that lovely crispiness, reheat the sprouts in a preheated oven or toaster oven at 375°F for about 10 minutes. Avoid the microwave if you want to keep the edges perfectly crispy instead of soggy.
FAQs
Can I use frozen Brussels sprouts for this recipe?
While fresh Brussels sprouts yield the best texture, you can use frozen if you thaw and dry them thoroughly first. Be aware that frozen sprouts may not crisp up as well as fresh ones.
What type of Parmesan cheese is best?
Freshly grated Parmesan Reggiano works best because it melts beautifully and adds a rich, nutty flavor. Pre-grated cheese often contains anti-caking agents that can affect texture.
Is balsamic vinegar necessary?
The balsamic vinegar is optional but highly recommended for a bright, tangy contrast that elevates the overall flavor. If you’re not a fan, feel free to leave it out without losing the essence of the dish.
How do I get the sprouts extra crispy?
Make sure the sprouts are dry before tossing with oil and that they’re spaced out on the baking sheet without overcrowding. Roasting at a high temperature and flipping halfway ensures maximum crispiness.
Can I make this recipe vegan?
Absolutely! Skip the Parmesan cheese or use a vegan cheese substitute. Adding nutritional yeast can provide a similar umami, cheesy flavor while keeping the dish plant-based.
Final Thoughts
You really can’t go wrong with this Crispy Parmesan Brussels Sprouts Recipe. It’s one of those dishes that literally turns people into Brussels sprouts lovers, thanks to its perfect balance of crisp, savory, and slightly sweet flavors. I’m genuinely excited for you to give it a try because it’s sure to become a staple on your table. Happy roasting!
