Parmesan Pesto Roasted Cauliflower Recipe

This Parmesan Pesto Roasted Cauliflower is a delightful dish that combines the nutty flavors of pesto and Parmesan with the earthiness of cauliflower. It’s an easy-to-prepare side dish that adds a gourmet touch to any meal.


  • 1 head of cauliflower, cut into florets
  • 3-4 tablespoons pesto
  • Salt and fresh ground black pepper, to taste
  • 1/4 cup shredded Parmesan cheese
  • Juice of 1/2 lemon


  1. Preheat Oven:
    • Preheat your oven to 400°F (200°C). This temperature is ideal for roasting cauliflower, allowing it to become tender on the inside while caramelizing on the outside.
  2. Prepare the Cauliflower:
    • Wash the cauliflower head and cut it into florets. Try to keep the florets similar in size for even cooking.
  3. Season the Cauliflower:
    • In a large mixing bowl, toss the cauliflower florets with the pesto, ensuring each piece is evenly coated. Season with salt and black pepper to your taste.
  4. Roast the Cauliflower:
    • Spread the pesto-coated cauliflower florets in a single layer on a baking sheet lined with parchment paper for easy cleanup.
    • Roast in the preheated oven for about 20-25 minutes, or until the cauliflower is tender and the edges are starting to brown. Halfway through, give the pan a good shake or stir to ensure even roasting.
  5. Add Parmesan and Lemon:
    • Once the cauliflower is roasted, remove it from the oven and immediately sprinkle with shredded Parmesan cheese. The heat from the cauliflower will help melt the cheese slightly.
    • Drizzle the lemon juice over the roasted cauliflower to add a fresh, zesty finish.
  6. Serve:
    • Transfer the roasted cauliflower to a serving dish. You may garnish with additional Parmesan or a few dollops of pesto if desired.
    • Serve warm as a side dish to complement a variety of main courses.


  • Choosing Pesto: You can use homemade or store-bought pesto. If you’re looking for a lighter version, consider using a pesto made with less oil.
  • Variations: For a vegan option, use a vegan pesto and substitute vegan Parmesan cheese.
  • Additional Flavors: To add more depth, consider roasting the cauliflower with a few cloves of garlic or mixing in some pine nuts for added crunch.
