Brussels sprouts often get a bad reputation, but when cooked the right way, they turn into a truly irresistible side dish. Roasting them brings out their natural sweetness, while the garlic and parmesan create a golden, savory crust that keeps you coming back for more. Whether you’re preparing a holiday spread, a weeknight dinner, or simply want a healthy snack, this garlic parmesan roasted Brussels sprouts recipe is a winner.
Let’s dive into the full step-by-step guide.
Ingredients You’ll Need
To make this flavorful dish, gather the following simple yet powerful ingredients:
- 16 oz Brussels sprouts (about 4 cups, trimmed and halved)
- 3 tablespoons olive oil
- ½ teaspoon salt
- ½ teaspoon black pepper
- 1 teaspoon Italian seasoning (a blend of oregano, basil, thyme, and rosemary)
- 3 garlic cloves, minced
- ½ cup grated parmesan cheese
These basic pantry staples work together to transform plain Brussels sprouts into a crunchy, cheesy, and savory side dish that pairs well with just about any main course.
Step-by-Step Instructions
Step 1: Preheat the Oven
Preheat your oven to 400°F (200°C). Roasting at high heat allows the Brussels sprouts to caramelize, creating that signature golden-brown crispness.
Step 2: Prepare the Brussels Sprouts
- Trim the bottom ends of the sprouts to remove the tough stem.
- Slice each sprout in half lengthwise (from top to bottom).
- Rinse under cold water to remove any dirt, then pat them thoroughly dry with a paper towel.
Tip: Moisture prevents crisping, so drying is essential for achieving a golden crust.
Step 3: Season the Brussels Sprouts
- Place the sprouts in a large mixing bowl.
- Add olive oil, salt, pepper, Italian seasoning, garlic, and parmesan.
- Toss gently until everything is evenly coated.
The parmesan and garlic will cling to the olive oil, ensuring each sprout roasts beautifully.
Step 4: Arrange on a Baking Sheet
- Line a large baking sheet with parchment paper for easy cleanup.
- Spread the seasoned sprouts in a single layer to allow even roasting.
If the sprouts overlap, they will steam instead of roasting, resulting in a softer texture rather than crispy edges.
Step 5: Roast to Perfection
- Roast for 25–30 minutes until golden brown and crispy around the edges.
- Halfway through cooking, give them a gentle stir to ensure even browning.
The parmesan will melt and form a savory crust, while the garlic infuses deep flavor.
Step 6: Serve and Enjoy
Remove from the oven, transfer to a serving dish, and serve hot. These sprouts are delicious on their own or paired with grilled meats, pasta, or roasted chicken.

Variations to Try
If you’d like to switch things up, try these fun variations:
- Spicy Kick – Add a pinch of red pepper flakes or cayenne.
- Balsamic Glaze – Drizzle with balsamic reduction just before serving.
- Extra Cheesy – Use a mix of parmesan and pecorino romano.
- Crunchy Texture – Sprinkle with toasted breadcrumbs or crushed nuts after roasting.
- Herb Upgrade – Swap Italian seasoning with fresh rosemary or thyme.
Storage and Reheating
- Refrigerate: Store leftovers in an airtight container in the fridge for up to 4 days.
- Reheat in Oven: Warm at 375°F (190°C) for 8–10 minutes to restore crispiness.
- Avoid Microwave: Microwaving makes them soggy, so use the oven or an air fryer instead.
Cooking Tips
- Always dry the sprouts well before roasting to ensure crispiness.
- Cut larger sprouts into quarters so they cook evenly with smaller ones.
- Don’t overcrowd the baking sheet – use two pans if necessary.
- For extra crunch, roast an additional 5 minutes but keep an eye on the parmesan to prevent burning.
