What Ingredients You Will Need

This recipe calls for straightforward, wholesome ingredients that come together to create a bold flavor and satisfying crunch without any fuss. Most of these are pantry staples, but I’ll also share some tips on picking the best Parmesan and fresh garlic to really make a difference.

• Brussels sprouts: About 1 pound (450g), trimmed and halved. Look for firm, vibrant green sprouts with tight leaves.
• Garlic: 3 cloves, minced fresh garlic is key for that punchy aroma.
• Parmesan cheese: ½ cup (50g), finely grated. I prefer Parmigiano-Reggiano from the deli counter for the best flavor and texture.
• Olive oil: 3 tablespoons, extra virgin if possible for richer taste.
• Salt: 1 teaspoon, kosher salt helps with even seasoning.
• Freshly ground black pepper: ½ teaspoon, adjust to taste.
• Optional: A pinch of red pepper flakes for a subtle heat kick.

If you want to tweak things, feel free to swap olive oil with avocado oil for a slightly different flavor or use Pecorino Romano instead of Parmesan for a sharper bite. For a dairy-free option, nutritional yeast sprinkled after roasting works surprisingly well. In summer, fresh herbs like thyme or rosemary can add a lovely fragrant twist.

Equipment Needed

• Baking sheet: A rimmed sheet pan works best to keep the sprouts from rolling off. I use a heavy-duty aluminum one that browns evenly.
• Mixing bowl: Large enough to toss the sprouts comfortably with oil and seasoning.
• Sharp knife: For trimming and halving the Brussels sprouts cleanly—makes a big difference in even cooking.
• Grater: A microplane or fine grater for the Parmesan to melt nicely over the sprouts.
• Spatula or tongs: For flipping the sprouts halfway through roasting.

If you don’t have a baking sheet, a cast-iron skillet can double as a roasting vessel and adds a nice crust. Just be cautious with timing, as cast iron retains heat differently. Also, keep your grater clean and dry for the best cheese texture—wet Parmesan can clump instead of crisp.

Preparation Method

1. Preheat the oven: Set to 425°F (220°C). This high heat is crucial for crispiness and caramelization. (About 10 minutes)
2. Prepare the Brussels sprouts: Trim the stem ends and remove any yellow or damaged outer leaves. Slice each sprout in half lengthwise for even roasting. (5 minutes)
3. Toss with garlic and oil: In a large bowl, combine the halved sprouts with the minced garlic, olive oil, salt, and black pepper. Make sure each sprout is coated well but not drenched. (3 minutes)
4. Arrange on the baking sheet: Spread the sprouts cut-side down in a single layer to maximize contact with the pan. Crowding will steam them instead of roasting. (2 minutes)
5. Roast for 20 minutes: Place in the oven and roast until the bottoms are deep golden brown and crispy. Halfway through, flip the sprouts using tongs or a spatula to roast evenly. (Flip at 10 minutes)
6. Add Parmesan: Remove the baking sheet briefly, sprinkle the grated Parmesan evenly over the sprouts, then return to the oven for another 5 minutes. This step crisps the cheese without burning it. (5 minutes)
7. Final check: The sprouts should be tender inside with a crispy, golden exterior and a fragrant garlic-Parmesan crust. If you want extra crispiness, broil for 1-2 minutes but watch closely to prevent burning. (Optional)
8. Serve immediately: Let cool for a minute, then transfer to a serving dish. Garnish with a little fresh cracked pepper or a sprinkle of parsley if you like. (Serve hot)

Pro tip: If your garlic starts to burn during roasting, toss the sprouts a bit sooner next time or mince the garlic finer and mix it in halfway through cooking. You’ll know it’s done when the kitchen smells nutty and the sprouts have that irresistible crunch.

Cooking Tips & Techniques

Getting perfectly crispy garlic Parmesan roasted Brussels sprouts takes a few tricks I’ve picked up the hard way. First, high heat is your friend. Roasting at 425°F (220°C) helps the sprouts caramelize rather than steam, which is what usually makes them soggy.

Halving the sprouts evenly is another key. If some pieces are bigger, they won’t cook at the same rate, leaving you with a mix of crunchy edges and undercooked centers. Use a sharp knife and steady hands—it pays off.

Don’t add the Parmesan too early! Sprinkle it on during the last 5 minutes of roasting to get that golden, crispy cheese layer without it burning or melting away entirely.

Oh, and garlic—fresh minced garlic roasts better than garlic powder here. But if you notice it browning too fast, toss the garlic in halfway through or reduce the oven temp slightly next time.

Multitasking tip: While the sprouts roast, clean your workspace or prep a simple dipping sauce like aioli. This keeps kitchen chaos down and makes the whole process feel smoother.

Variations & Adaptations

• Spicy kick: Add ¼ teaspoon of smoked paprika or red pepper flakes to the garlic-oil mix for a smoky heat that pairs beautifully with the Parmesan.
• Vegan option: Swap Parmesan for nutritional yeast and use a plant-based oil like avocado or coconut oil. The nutritional yeast adds a cheesy umami punch without dairy.
• Herb-infused: Toss in fresh thyme or rosemary sprigs before roasting for an earthy aroma that changes the flavor profile quite nicely.
• Different cheese: Experiment with Pecorino Romano for a saltier, sharper taste, or Asiago for a nuttier finish. Just remember to adjust salt accordingly.
• Cooking method: Tried air-frying these at 400°F (205°C) for about 15 minutes with a shake halfway through—results in an even crispier texture!

One personal favorite is adding a squeeze of fresh lemon juice right before serving—it brightens the richness and makes the sprouts even more addictive.

Serving & Storage Suggestions

Serve these crispy garlic Parmesan roasted Brussels sprouts hot from the oven. The texture is at its peak right then—the crunch, the aromatic garlic, the melty cheese—it’s all there. They make a fantastic side for roasted chicken, grilled steak, or even a simple pasta dish.

If you want to prepare ahead, store leftovers in an airtight container in the fridge for up to 3 days. To reheat, spread them out on a baking sheet and warm in a 375°F (190°C) oven for about 10 minutes to bring back the crispiness. Avoid microwaving if you want to keep that crunch.

Flavors actually deepen overnight, making them a great make-ahead snack or side. Just remember, reheating is key to restoring their signature crisp texture.

FAQs

Can I use frozen Brussels sprouts for this recipe?

Frozen Brussels sprouts tend to be softer and hold more water, which can prevent crispiness. If you must use frozen, thaw and pat them very dry before roasting, but fresh sprouts work best.

How do I prevent the garlic from burning?

Minced fresh garlic can burn if roasted too long at high heat. To avoid this, add garlic halfway through roasting or toss it with the sprouts just before the last 10 minutes.

Can I prepare this recipe ahead of time?

You can trim and halve the sprouts a day ahead and store them in the fridge. For best texture, roast them fresh just before serving.

What’s the best way to clean Brussels sprouts?

Trim the stem ends and peel off any yellow or damaged outer leaves. Give them a quick rinse and dry thoroughly before cooking to avoid steaming.

Is this recipe suitable for a vegan diet?

Yes! Simply replace Parmesan with nutritional yeast and use a plant-based oil. This keeps the cheesy, savory flavor without animal products.
