Course Dinner
Servings 8


  • 1.5 cups uncooked white quinoa rinsed
  • 24 oz. marinara sauce
  • 1 cup water
  • 2 teaspoons Italian seasoning
  • 3 cloves garlic minced
  • ½ medium white onion minced and separated
  • 2 cups shredded mozzarella cheese
  • cup grated Parmesan cheese
  • 6 oz. pepperoni


  • Preheat your oven to 375ºF.
  • In a casserole dish, combine the quinoa, marinara sauce, water, Italian seasoning, minced garlic, and half of the minced onion. Stir well until the quinoa is fully coated in the sauce.
  • Cover the casserole dish and bake for 30 minutes.
  • After 30 minutes, give the casserole a stir, ensuring the edges are wiped clean to prevent burning. Recover and bake for an additional 20-30 minutes until most of the liquid is absorbed, and the quinoa is tender.
  • Once cooked, uncover the casserole and sprinkle the shredded mozzarella cheese evenly over the top. Arrange the pepperoni slices on top of the cheese.
  • Bake the casserole uncovered for an additional 10 minutes until the cheese is melted and bubbly.
  • Remove from the oven and allow it to rest for 10 minutes before serving.
  • Garnish with dried oregano for an extra burst of flavor, and enjoy your hearty and nutritious meal!


  • Ensure the ratio of quinoa to liquid is 1.5 cups quinoa to 4 cups liquid.
  • Feel free to use broth instead of water for added flavor.
  • For a spicy kick, add ½-1 teaspoon of red pepper flakes to the casserole.
  • If you’re out of marinara or pizza sauce, canned tomato sauce works too! Just adjust the seasoning accordingly.
