Ingredients

• 1 large head cauliflower, cut into bite-sized florets
• 3 tablespoons olive oil
• 4 cloves garlic, finely minced
• ½ cup grated parmesan cheese
• 1 teaspoon salt
• ½ teaspoon black pepper
• ½ teaspoon paprika (optional for color and mild smokiness)
• 1 tablespoon chopped fresh parsley (for garnish)
• ½ teaspoon garlic powder (optional for extra flavor)

Instructions

1. Preheat the oven
   Preheat your oven to 425°F (220°C). A high temperature is essential for achieving crispy roasted cauliflower.
2. Prepare the cauliflower
   Wash the cauliflower and pat it dry thoroughly. Cut it into evenly sized florets so they cook at the same rate.
3. Season the cauliflower
   Place the florets in a large mixing bowl. Add olive oil, minced garlic, salt, pepper, paprika, and garlic powder. Toss until the cauliflower is evenly coated.
4. Arrange on a baking sheet
   Spread the cauliflower in a single layer on a baking sheet lined with parchment paper or lightly greased. Avoid overcrowding, as this prevents proper roasting.
5. Roast the cauliflower
   Place the tray in the oven and roast for 20 minutes, turning the florets halfway through to ensure even browning.
6. Add parmesan cheese
   Remove the tray briefly and sprinkle grated parmesan over the cauliflower. Return it to the oven for another 5–10 minutes until the cheese melts and the florets turn golden brown.
7. Finish with garnish
   Remove from the oven and sprinkle chopped fresh parsley and extra parmesan if desired.
8. Serve immediately
   Serve warm while the edges are crispy and the cheese is perfectly melted.

Tips for Perfect Roasted Cauliflower

1. Dry the Cauliflower Well

Excess moisture can cause the cauliflower to steam rather than roast. Pat it completely dry after washing.

2. Use High Heat

Roasting at 425°F allows the cauliflower to caramelize and develop crispy edges.

3. Don’t Crowd the Pan

Spread florets evenly on the baking sheet. If necessary, use two trays to ensure proper roasting.

4. Add Cheese Near the End

Adding parmesan too early can cause it to burn. Sprinkle it during the final minutes of roasting.

5. Cut Even Pieces

Uniform florets cook evenly and prevent some pieces from burning while others remain undercooked.
