Ingredients
- 1 medium head cauliflower, cut into florets
- 2 tablespoons olive oil
- ½ teaspoon garlic powder
- ½ teaspoon paprika
- Salt and black pepper to taste
- ½ cup grated Parmesan cheese
- Optional: chopped parsley, lemon zest, or crushed red pepper flakes for garnish
Substitutions
- Olive Oil: Avocado oil or melted butter will work for a richer flavor.
- Parmesan Cheese: Pecorino Romano, Asiago, or nutritional yeast for a vegan option.
- Spices: Smoked paprika, Italian seasoning, chili powder, or a pinch of cayenne can add different flavor profiles.
- Cauliflower: Broccoli or Romanesco can be used for variation.
Instructions
- Preheat the Oven
Preheat your oven to 425°F (220°C) and line a baking sheet with parchment paper. This prevents sticking and makes cleanup easier. - Prepare the Cauliflower
Wash and trim the cauliflower, cutting it into uniform bite-sized florets. In a large mixing bowl, toss the florets with olive oil, garlic powder, paprika, salt, and black pepper until evenly coated. - Arrange for Roasting
Spread the cauliflower on the baking sheet in a single layer. Avoid overcrowding — this ensures the florets roast instead of steam. - Roast to Perfection
Roast in the preheated oven for 20–25 minutes, flipping halfway through. The florets should develop golden edges and a tender interior. - Add Parmesan
Sprinkle grated Parmesan over the cauliflower and return to the oven for an additional 5 minutes, until the cheese melts and lightly browns. - Garnish and Serve
Remove from the oven and garnish with chopped parsley, lemon zest, or crushed red pepper flakes for added freshness and color. Serve immediately for maximum crispiness.

Cooking Tips and Tricks
- Uniform Size: Cutting florets into similar sizes ensures even cooking.
- Crispy Edges: Don’t overcrowd the pan; give each floret some space.
- Extra Flavor: Add minced fresh garlic or shallots for an aromatic boost.
- Crispier Cauliflower: Roast at a high temperature and turn the florets halfway through cooking.
- Cheese Alternatives: Mix Parmesan with a little shredded mozzarella for a gooey texture.
Serving Suggestions
- Serve as a side dish with roasted chicken, steak, or fish.
- Toss into a salad or grain bowl for added texture and flavor.
- Add to pasta dishes for a cheesy, roasted vegetable component.
- Pair with creamy dips like garlic aioli, ranch, or tahini for a flavorful appetizer.
- Sprinkle with toasted nuts or seeds for extra crunch and protein.
Storage and Reheating
- Refrigeration: Store leftovers in an airtight container for up to 3 days.
- Reheating: Warm in the oven at 350°F (175°C) for 5–7 minutes to restore crispiness. Avoid microwaving, as it can make the cauliflower soggy.
- Freezing: You can freeze roasted cauliflower, but the texture may change slightly. Reheat in the oven for best results.
