Ingredients

Here’s everything you’ll need to whip up this delicious side dish:

Base Ingredients:

• 16 oz (450g) Brussels sprouts: Fresh is best for this recipe. Look for bright green, firm sprouts without yellowing leaves.
• 3 tablespoons olive oil: Adds richness and helps the Brussels sprouts crisp up beautifully. You can substitute with melted butter for a richer flavor.
• 1/2 teaspoon kosher salt and freshly cracked black pepper: Enhances the natural flavors of the dish. Adjust to taste.

Flavor Boosters:

• 1 teaspoon Italian seasoning: A blend of dried herbs like oregano, basil, and thyme adds subtle earthiness.
• 3 garlic cloves, minced: Fresh garlic gives the dish that irresistible aroma. You can use pre-minced garlic for convenience, but freshly minced is always best.
• 1/2 cup grated Parmesan cheese: Adds a nutty, salty kick. Feel free to adjust the quantity to your preference (more is always better!).

Step-by-Step Instructions

Let’s get started!

1. Prep the Oven and Baking Sheet

Preheat your oven to 400ºF (200ºC) and position the rack in the middle. This ensures even cooking.
If desired, line a large rimmed baking sheet with parchment paper to make cleanup easier.

2. Prepare the Brussels Sprouts

• Rinse the Brussels sprouts under cold water to remove any dirt.
• Trim the bottom stem of each sprout and peel away any yellow or damaged outer leaves.
• Slice each sprout in half lengthwise. This not only speeds up cooking but also ensures a crispier texture.

3. Season the Brussels Sprouts

• Pat the sprouts dry with paper towels. Moisture is the enemy of crispiness, so make sure they’re as dry as possible.
• In a large mixing bowl, combine the Brussels sprouts with olive oil, Italian seasoning, garlic, Parmesan cheese, salt, and pepper.
• Toss gently to ensure every piece is evenly coated.

4. Arrange on the Baking Sheet

• Spread the seasoned Brussels sprouts onto the prepared baking sheet in a single layer.
• Make sure the cut sides are facing down—this helps them caramelize beautifully.

5. Roast to Perfection

• Roast in the preheated oven for 25–30 minutes, flipping halfway through for even cooking.
• You’re looking for a golden-brown color with crispy edges. The garlic and Parmesan will form a delicious crust on the sprouts.

6. Serve and Enjoy

• Once out of the oven, transfer the roasted Brussels sprouts to a serving bowl.
• Garnish with fresh parsley for a pop of color (optional).
• Serve immediately and watch them disappear!

How to Serve

These Garlic Parmesan Roasted Brussels Sprouts are versatile and pair beautifully with a variety of dishes. Here are some serving ideas:

• As a Side Dish: Perfect alongside roasted chicken, grilled salmon, or a hearty beef stew.
• In a Salad: Toss with baby spinach, dried cranberries, toasted almonds, and a balsamic vinaigrette for a satisfying salad.
• As a Snack: These are so tasty, they can double as a healthy, savory snack!

Additional Tips for Success

1. Don’t Overcrowd the Pan: Make sure the Brussels sprouts are spread out in a single layer. Overcrowding can lead to steaming instead of roasting.
2. Use Fresh Parmesan: Pre-grated Parmesan may contain anti-caking agents that prevent it from melting as nicely. Grate your own for the best flavor and texture.
3. Get Creative with Add-Ins: Try sprinkling some crushed red pepper flakes for heat or adding chopped nuts like pecans or walnuts for crunch.
4. Adjust the Cooking Time: Oven temperatures can vary, so start checking the sprouts around the 20-minute mark to avoid overcooking.
5. Use a High-Quality Olive Oil: Since olive oil is a key ingredient, using a good-quality one can make a noticeable difference in flavor.

Variations to Try

1. Cheesy Upgrade

Swap the Parmesan for shredded mozzarella or Gruyère. Let the cheese melt during the last 5 minutes of roasting for a gooey finish.

2. Spicy Twist

Add 1/4 teaspoon of cayenne pepper or a dash of hot sauce to the seasoning mix for a spicy kick.

3. Sweet and Savory

Drizzle the roasted Brussels sprouts with a bit of honey or maple syrup for a touch of sweetness.

4. Vegan Option

Omit the Parmesan cheese and sprinkle with nutritional yeast instead. You’ll still get that cheesy flavor without the dairy.

Storage and Reheating

If you have leftovers (a big if), here’s how to store them:

Refrigerator:

Place the roasted Brussels sprouts in an airtight container and refrigerate for up to 3 days.

Freezer:

While these are best enjoyed fresh, you can freeze them for up to 2 months. To reheat, bake at 350°F (175°C) until warmed through.

Frequently Asked Questions

1. Can I make this recipe ahead of time?

Absolutely! You can prep the Brussels sprouts and season them up to 8 hours in advance. Just store them in the fridge until ready to roast.

2. What if I don’t have Italian seasoning?

No problem! Use a mix of dried oregano, thyme, and basil instead.

3. Can I use frozen Brussels sprouts?

Fresh is best for this recipe, but if using frozen, make sure to thaw and pat them dry thoroughly before roasting.
