  • 1 head cauliflower cut into florets
  • 1 tablespoon avocado oil
  • 1 teaspoon smoked paprika
  • ½ teaspoon sea salt
  • ¼ teaspoon fresh ground black pepper

  • Preheat oven to 350 degrees. Line a baking sheet with parchment paper.
  • In a large bowl, toss the cauliflower with the avocado oil, smoked paprika, salt, and pepper. Arrange the florets in a single layer and bake for 18 minutes.
