  • 1 ½ cups marinara sauce
  • 1 ½ cups shredded mozzarella cheese, divided
  • 1 cup chopped bell peppers
  • ½ cup sliced black olives
  • ½ cup diced onions
  • 2 cloves garlic, minced
  • 1 teaspoon dried oregano
  • ¼ teaspoon crushed red pepper flakes
  • 1 cup sliced mushrooms
  • 1 tablespoon olive oil
  • ½ teaspoon salt

Instructions

  1. Preheat your oven to 375°F and grease a 9×13 inch baking dish.
  2. Cook quinoa according to package instructions and set aside to cool slightly.
  3. In a large bowl, mix the cooked quinoa, marinara sauce, ¾ cup cheese, bell peppers, onions, mushrooms, olives, garlic, oregano, red pepper flakes, and salt.
  4. Spread olive oil in the baking dish to prevent sticking, then pour in the quinoa mixture and spread evenly.
  5. Top with remaining mozzarella cheese.
  6. Bake uncovered for 25–30 minutes until the cheese is golden and bubbly.
  7. Let rest for 5 minutes before serving. Garnish with herbs if desired.

Notes

  • Rinse quinoa before cooking to avoid bitterness.
  • Use thick marinara to prevent a watery casserole.
  • Customize with your favorite pizza toppings or veggies.
  • Let it rest after baking to help it set properly.
