Learn the best way to roast cauliflower to achieve maximum crispiness, coated in savory Parmesan cheese. This simple, healthy roasted side dish is perfect for weeknights.

Ingredients

Scale
  • 1 large head cauliflower, cut into uniform florets
  • 3 tablespoons olive oil
  • 1/2 cup grated Parmesan cheese, finely grated
  • 1 teaspoon garlic powder
  • 1/2 teaspoon kosher salt
  • 1/4 teaspoon black pepper

Instructions

  1. Preheat your oven to 425 degrees Fahrenheit. Position an oven rack in the middle position.
  2. In a large bowl, toss the cauliflower florets with the olive oil until they are evenly coated.
  3. Spread the oiled cauliflower in a single layer on a large, rimmed baking sheet. Do not overcrowd the pan; use two sheets if necessary for best results.
  4. Roast for 15 minutes.
  5. Remove the pan from the oven. Sprinkle the garlic powder, salt, and pepper over the cauliflower. Toss gently.
  6. Sprinkle the grated Parmesan cheese evenly over the cauliflower.
  7. Return the pan to the oven and roast for another 10 to 15 minutes, or until the edges of the cauliflower are deeply browned and the cheese is melted and crispy.
  8. Serve immediately as a healthy roasted side dish or a low carb roasted vegetable option.

Notes

  • For the crispiest results, ensure your cauliflower florets are completely dry before adding oil. Pat them thoroughly with paper towels.
  • Do not stir the cauliflower while it roasts the first time; this allows the bottom side to brown and crisp up.
  • If you want a garlic parmesan cauliflower flavor boost, add 1/2 teaspoon of dried Italian seasoning with the initial spices.
  • This recipe adapts well to an air fryer: cook at 380 degrees Fahrenheit for 12-15 minutes, tossing halfway, then add cheese for the last 3 minutes.
