  • 1 large head cauliflower, chopped into bit sized florets

  • 1/2 teaspoon paprika
  • 1/4 teaspoon garlic powder
  • 1/4 teaspoon onion powder
  • 1 teaspoon salt, or more to taste


  • Preheat oven to 425 degrees and spray a large sheet pan or two smaller sheet pans with oil. Or use parchment paper.
  • Add all spices to a small bowl and mix. Set aside.
  • Place the chopped cauliflower, peppers, onions, spice mixture and olive oil in a large bowl. Mix well.
  • Add the mixture to sheet pan(s) and roast for 20-25 minutes, until the vegetables are soft with a crisp edge.

  1. May omit oil and use water or vegetable broth, but watch them carefully in the oven so they don't burn. It may help to cover the vegetables in foil for the first half of cooking if not using oil.
