Ingredients

Scale

Vegetables

  • 4 cups cauliflower florets
  • 1 cup bell peppers, chopped

Dairy

  • 2 cups shredded mozzarella cheese, divided

Other

  • 2 tablespoons olive oil
  • 1 cup marinara sauce
  • 30 slices pepperoni, divided
  • Nonstick cooking spray, for baking dish

Instructions

  1. Preheat Oven: Preheat your oven to 400°F (200°C) and spray a baking dish with nonstick cooking spray to prepare for the casserole.
  2. Roast Cauliflower: Toss the cauliflower florets with olive oil in a large bowl until they are evenly coated. Spread them out on a baking sheet, then roast in the preheated oven for 20 minutes until tender and slightly browned, stirring halfway through for even cooking.
  3. Mix Ingredients: In a separate bowl, combine the roasted cauliflower with marinara sauce, half of the shredded mozzarella cheese, chopped bell peppers, and half of the pepperoni slices. Mix well to incorporate all ingredients evenly.
  4. Assemble Casserole: Pour the cauliflower mixture into the prepared baking dish. Evenly distribute the remaining mozzarella cheese and pepperoni slices on top to ensure a flavorful, cheesy crust.
  5. Bake Casserole: Place the baking dish back in the oven and bake for an additional 15-20 minutes, or until the cheese on top is bubbly and golden brown, indicating the casserole is fully heated through and ready to serve.

Notes

  • You can substitute pepperoni with cooked sausage or omit for a vegetarian version (omit pepperoni and add more veggies).
  • For extra flavor, sprinkle some Italian seasoning or red pepper flakes before baking.
  • Use low-moisture mozzarella for best melting results.
  • Make sure to stir the cauliflower halfway through roasting for even browning.
  • Let the casserole cool for a few minutes before serving to help it set.
