You will love this simple recipe for oven-roasted broccoli that achieves incredibly crispy edges while staying tender inside. Seasoned with garlic and Parmesan, this is the best healthy vegetable side dish for any weeknight dinner or holiday meal.

Ingredients

Scale
  • 2 large heads of broccoli, cut into uniform florets
  • 3 tablespoons olive oil
  • 3 cloves garlic, minced
  • 1/2 teaspoon kosher salt
  • 1/4 teaspoon black pepper
  • 1/2 cup grated Parmesan cheese
  • 1 teaspoon lemon juice (optional, for brightness)

Instructions

  1. Preheat your oven to 425°F (220°C). Line a large baking sheet with parchment paper for easy cleanup.
  2. In a large bowl, toss the broccoli florets with the olive oil, minced garlic, salt, and pepper until every piece is evenly coated.
  3. Spread the seasoned broccoli in a single layer on the prepared baking sheet. Do not overcrowd the pan; use two sheets if necessary to ensure crispiness.
  4. Roast for 12 to 15 minutes, until the edges start to turn golden brown and look slightly charred.
  5. Remove the pan from the oven. Sprinkle the grated Parmesan cheese evenly over the hot broccoli.
  6. Return the pan to the oven and roast for another 3 to 5 minutes, or until the cheese is melted and lightly browned.
  7. Remove from the oven. Drizzle with fresh lemon juice, if using, and serve immediately for the best crispy texture.

Notes

  • For the crispiest results, make sure your oven is fully preheated and do not skip the single-layer arrangement on the baking sheet.
  • You can substitute garlic powder for fresh garlic if you prefer a milder flavor, using 1 teaspoon of powder instead of 3 cloves.
  • This recipe is excellent for meal prep; reheat in a toaster oven or air fryer to restore crispness.
