Ingredients

  • 1 large head Cauliflower chopped into florets
  • 1 pint Cherry Tomatoes
  • 1 medium Red Onion sliced into wedges
  • 2 tbsp Extra Virgin Olive Oil
  • ½ tsp Garlic Powder
  • Salt and Pepper to taste
  • ¼ cup Pesto* plus more for drizzling
  • Juice of 1/2 a Lemon
  • Parmesan Cheese grated, optional, for serving

Instructions

  • Preheat your oven to 425°F (220°C). Line a large baking sheet with parchment paper or foil.
  • In a large bowl, toss the cauliflower, cherry tomatoes, and red onion with olive oil, garlic powder, salt, and pepper. Make sure everything’s coated well.

  • Dump everything onto the baking sheet in an even layer but don’t crowd them! Use two pans if needed for max crispiness.

  • Roast for 25–30 minutes, tossing halfway through. You want the cauliflower to be golden and crispy on the edges, the tomatoes blistered, and the onions softened and lightly caramelized.
