Garlic Parmesan Roasted Cauliflower Recipe

A Side Dish That Even Cauliflower Skeptics Love

I’ll be honest—I wasn’t always a huge cauliflower fan. It seemed a little plain until I started roasting it. The first time I made this Garlic Parmesan Roasted Cauliflower, the edges turned beautifully golden, the garlic became fragrant, and the Parmesan created the most delicious crispy coating. Now it’s one of those recipes I make whenever I want an easy vegetable side that everyone actually enjoys.

I usually serve it with roasted chicken, grilled steak, or even pasta, and there are rarely any leftovers.

Ingredients

1 large head cauliflower, cut into florets
3 tablespoons olive oil
3 cloves garlic, minced
½ cup grated Parmesan cheese
1 teaspoon paprika
1 teaspoon Italian seasoning
½ teaspoon garlic powder
½ teaspoon onion powder
½ teaspoon salt
¼ teaspoon black pepper
1 tablespoon chopped fresh parsley (for garnish)
Optional: 1 teaspoon lemon zest

Step-by-Step Instructions

Step 1: Preheat the Oven

Preheat your oven to 425°F (220°C). Line a baking sheet with parchment paper or lightly grease it.

Step 2: Prepare the Cauliflower

Wash and dry the cauliflower thoroughly. Cut it into evenly sized florets so they cook at the same rate.

Step 3: Season Everything

In a large bowl, combine the olive oil, minced garlic, paprika, Italian seasoning, garlic powder, onion powder, salt, and black pepper. Add the cauliflower and toss until every piece is evenly coated.

Step 4: Add the Parmesan

Sprinkle the Parmesan cheese over the cauliflower and toss again so the cheese sticks to each floret.

Step 5: Roast

Arrange the cauliflower in a single layer on the baking sheet, leaving space between the florets.

Roast for 25–30 minutes, turning halfway through, until the cauliflower is tender and the edges are golden brown and crispy.

Step 6: Garnish and Serve

Remove from the oven and sprinkle with fresh parsley and optional lemon zest. Serve immediately while hot and crispy.

Cooking Tips

Dry the cauliflower well before seasoning to help it roast instead of steam.
Don’t overcrowd the baking pan—space allows the florets to caramelize.
Freshly grated Parmesan melts and crisps better than pre-shredded cheese.
Flip the florets halfway through cooking for even browning.
For extra crispiness, broil for the last 2 minutes while watching carefully.
