Ingredients and Substitutions

Let’s gather the ingredients for this delightful dish:

  • 16 oz (450g) Brussels sprouts, trimmed and halved
  • 3 tbsp olive oil (or melted butter)
  • 1/2 tsp kosher salt and freshly cracked black pepper
  • 1 tsp Italian seasoning
  • 3 garlic cloves, minced

  • Olive oil: Melted butter or vegetable oil
  • Italian seasoning: Dried oregano or thyme
  • Parmesan cheese: Pecorino Romano or Asiago


Now, let’s dive into the steps to create this flavorful side dish:

Step 1: Preheat and Prepare

Preheat your oven to 400ºF (200ºC) and prepare a large baking sheet by lining it with parchment paper or lightly greasing it.

Step 2: Prep Brussels Sprouts

Pat dry the Brussels sprouts, trim the ends, and cut them in half. Place them in a mixing bowl.

Step 3: Coat with Flavors

Add olive oil, Italian seasoning, minced garlic, grated Parmesan, kosher salt, and black pepper to the bowl with Brussels sprouts. Toss gently to coat evenly.

Step 4: Roast to Perfection

Spread the coated Brussels sprouts on the prepared baking sheet and bake for 25-30 minutes or until they turn golden brown and crispy.

Step 5: Serve and Enjoy

Transfer the roasted Brussels sprouts to a serving bowl, sprinkle with fresh chopped parsley if desired, and savor the deliciousness!

Top 4 Mistakes and How to Avoid Them

Mistake 1: Overcrowding the Baking Sheet

Ensure the Brussels sprouts are spread evenly on the baking sheet to allow proper roasting. Overcrowding can result in uneven cooking and a less crispy texture.

Mistake 2: Neglecting to Pat Dry

Patting dry the Brussels sprouts before coating them ensures they crisp up during roasting. Excess moisture can lead to steaming rather than roasting.

Mistake 3: Forgetting to Toss Gently

Gently tossing the ingredients ensures an even distribution of flavors. Avoid aggressive mixing, as it may cause the Parmesan to clump or the sprouts to break apart.

Mistake 4: Overcooking the Sprouts

Keep an eye on the sprouts in the oven to prevent overcooking. Once they achieve a golden brown color, they are ready to be enjoyed. Overcooking can result in a bitter taste.


Q1: Can I use frozen Brussels sprouts for this recipe?

Fresh Brussels sprouts are recommended for the best texture and flavor. Frozen sprouts may release excess water during roasting, affecting the crispiness.

Q2: How can I make this recipe vegan?

Replace Parmesan cheese with a vegan alternative, and use melted vegan butter or olive oil. The result is a delicious vegan version of this dish.

Q3: Can I prepare this dish in advance?

You can pre-cut the Brussels sprouts and mix the ingredients in advance. However, for the best flavor and texture, roast them just before serving.

Q4: What other seasonings can I add?

Feel free to experiment with additional seasonings like paprika, onion powder, or chili flakes to customize the flavor to your liking.

Q5: Can I reheat leftovers?

To retain the crispiness, it’s best to reheat

leftovers in the oven or an air fryer for a few minutes. Microwave reheating may result in a softer texture.


Congratulations! You’ve now mastered the art of creating Garlic Parmesan Roasted Brussels Sprouts. This delightful side dish is not only a treat for your taste buds but also a visual feast. Whether you’re hosting a dinner party or preparing a family meal, this recipe is sure to be a hit. Get ready to enjoy the perfect blend of crispy Brussels sprouts, savory Parmesan, and aromatic garlic. Happy cooking!
