Instructions

Step 1: Preheat the Oven

Preheat your oven to 425°F (220°C). Line a baking sheet with parchment paper for easy cleanup.

Step 2: Prepare the Cauliflower

Wash and dry the cauliflower thoroughly. Cut into evenly sized florets to ensure even roasting.

  • Olive oil

Make sure every floret is well coated.

Remove from oven, sprinkle Parmesan evenly over the cauliflower, then return to oven for 10 more minutes, until golden and crispy.

Step 6: Serve

Garnish with parsley or extra Parmesan. Serve immediately while hot and crispy.

Tips for Extra Crispy Cauliflower

  • Don’t overcrowd the pan

  • Dry cauliflower well before seasoning

  • Use freshly grated Parmesan

  • Roast at high heat (425°F)

Variations

  • Spicy: Add red pepper flakes

  • Lemon Garlic: Finish with lemon zest

  • Vegan: Use dairy-free Parmesan alternative

  • Extra Cheesy: Add mozzarella in last 5 minutes

Making Garlic Parmesan Roasted Cauliflower is even easier when you have the right kitchen tools. These are the exact essentials I use and recommend:

  • Large Baking Sheet - A sturdy baking sheet ensures the cauliflower roasts evenly and gets perfectly crispy without sticking.
  • Parchment Paper or Silicone Baking Mat - Prevents sticking and makes cleanup quick and easy — especially helpful when roasting cheese-covered vegetables. 
  • Chef’s Knife - A sharp chef’s knife makes it easier to cut cauliflower into evenly sized florets for consistent roasting.
