Ingredients
- 16 oz (450 g) Brussels sprouts, trimmed, halved, and rinsed
- 3 tablespoons olive oil (or melted butter)
- 1/2 teaspoon kosher salt
- 1/2 teaspoon freshly cracked black pepper
- 1 teaspoon Italian seasoning
- 3 to 4 cloves garlic, minced
- 1/2 to 3/4 cup freshly grated Parmesan cheese
Optional additions:
- Red pepper flakes for heat
- Fresh lemon zest or juice for brightness
- Balsamic glaze for a sweet finish
- Fresh parsley for garnish
Choosing the Best Brussels Sprouts
The quality of your Brussels sprouts will significantly affect the final result. Look for sprouts that are:
- Bright green and firm to the touch
- Compact, with tightly packed leaves
- Similar in size for even cooking
Avoid sprouts that are yellowing, soft, or have loose leaves. Smaller Brussels sprouts tend to be sweeter and more tender, while larger ones may have a stronger flavor but still roast beautifully when cut evenly.
If possible, buy them loose rather than pre-packaged so you can select the freshest ones individually.
Preparing the Brussels Sprouts
Proper preparation is key to achieving crisp, caramelized results.
- Trim the ends: Slice off the tough stem end of each sprout.
- Remove damaged leaves: Peel away any yellow or wilted outer leaves.
- Halve evenly: Cut each sprout in half lengthwise. Larger sprouts can be quartered.
- Rinse and dry thoroughly: After rinsing, pat them completely dry with a clean kitchen towel. Moisture is the enemy of crispiness.
Drying thoroughly ensures that the sprouts roast rather than steam in the oven.
Step-by-Step Instructions
1. Preheat the Oven
Preheat your oven to 400°F (200°C). For extra crispiness, you can go slightly higher to 425°F (220°C), but keep an eye on them to prevent burning.
Line a large baking sheet with parchment paper or use a lightly greased sheet pan.
2. Season the Sprouts
In a large mixing bowl, combine:
- Brussels sprouts
- Olive oil or melted butter
- Kosher salt
- Freshly cracked black pepper
- Italian seasoning
- Minced garlic
Toss thoroughly until every sprout is evenly coated. The oil ensures even roasting and helps the Parmesan adhere later.
3. Arrange for Maximum Crisp
Spread the sprouts in a single layer on the baking sheet, cut-side down. Do not overcrowd the pan. Overcrowding causes steaming and prevents proper caramelization.
If necessary, use two baking sheets to ensure adequate space between sprouts.
4. Roast
Place the baking sheet in the preheated oven and roast for 20 to 25 minutes.
Halfway through cooking, flip the sprouts for even browning. You are looking for:
- Deep golden edges
- Crisp outer leaves
- Tender centers when pierced with a fork
5. Add Parmesan
During the last 5 minutes of roasting, sprinkle freshly grated Parmesan cheese evenly over the sprouts.
Return them to the oven until the cheese melts and turns slightly golden.
For extra crisp cheese edges, you can switch the oven to broil for 1 to 2 minutes, watching carefully to prevent burning.
6. Serve
Remove from the oven and let them rest for a few minutes. Optional: finish with lemon zest, a squeeze of fresh lemon juice, or a drizzle of balsamic glaze for added brightness and complexity.
Serve warm for best texture and flavor.
Tips for Perfect Roasted Brussels Sprouts
Dry Them Completely
Even small amounts of moisture can prevent browning. After rinsing, pat dry thoroughly.
Use Enough Oil
Too little oil leads to dryness; too much can cause sogginess. Three tablespoons for 16 ounces is the ideal balance.
Roast Cut-Side Down
This maximizes surface contact with the pan, creating beautifully caramelized flat edges.
Do Not Overcrowd
Space allows heat to circulate and promotes crispiness.
Freshly Grated Parmesan Matters
Pre-shredded cheese often contains anti-caking agents that prevent proper melting. Grate your own for the best texture and flavor.
Flavor Variations
This recipe is highly adaptable. Try these variations to suit your taste.
Spicy Garlic Parmesan
Add 1/2 teaspoon red pepper flakes or a drizzle of hot honey before serving.
Lemon Garlic Parmesan
Add fresh lemon zest before roasting and a squeeze of lemon juice after baking.
Balsamic Parmesan
Drizzle balsamic glaze over the finished sprouts for a sweet and tangy finish.
Bacon and Parmesan
Add cooked, crumbled bacon during the last 5 minutes of roasting for a smoky twist.
Herb-Forward Version
Add fresh thyme or rosemary for a more aromatic flavor profile.

Make-Ahead and Storage Instructions
Make-Ahead
You can trim and halve the Brussels sprouts up to one day in advance. Store them in an airtight container in the refrigerator until ready to roast.
Storing Leftovers
Store leftovers in an airtight container in the refrigerator for up to 3 days.
Reheating
For best results, reheat in a 375°F (190°C) oven for 8 to 10 minutes. Avoid microwaving if possible, as it softens the crispy edges.
Freezing
While possible, freezing is not ideal as it can alter texture. For best quality, enjoy fresh.
