Ingredients You’ll Need
- Tomatoes – 2 cups crushed tomatoes for the sauce and fresh grape or cherry tomatoes for the top.
- Quinoa – uncooked quinoa cooked in chicken broth for extra flavor.
- Chicken – shredded rotisserie chicken is convenient and flavorful; use any cooked chicken or turkey you prefer.
- Chicken broth – for cooking quinoa; low-sodium broth, vegetable broth, or water also work.
- Garlic – fresh minced garlic or jarred minced garlic.
- Tomato paste – deepens color and thickens the sauce.
- Balsamic vinegar – use good-quality balsamic for best flavor.
- Half and half – makes the sauce creamy; coconut milk or heavy cream can substitute.
- Cheese – grated Parmesan and shredded mozzarella.
- Fresh basil – essential for finishing the casserole.
- Seasonings – crushed red pepper flakes (optional), salt and black pepper.
How to Make Caprese Quinoa Casserole
- Cook the quinoa. Rinse and soak quinoa about 10 minutes. Bring 2 cups chicken broth to a boil, drain the quinoa and add it to the boiling broth. Cover, reduce heat to a simmer and cook 12–15 minutes. Turn off the heat and let sit 5 minutes, then fluff with a fork.
- Make the sauce. In a medium saucepan, simmer crushed tomatoes with garlic, tomato paste and balsamic vinegar. Stir in half and half, crushed red pepper (if using), salt and pepper, and heat through.
- Combine ingredients. In a large bowl, mix the shredded chicken, cooked quinoa, Parmesan and 1/2 cup of the mozzarella. Stir in the sauce until evenly combined.
- Bake the casserole. Transfer the mixture to a prepared 9×13 baking dish. Top with the remaining mozzarella and halved tomatoes. Bake at 375°F (190°C) for 12–15 minutes, until the cheese is melted and the casserole is heated through. Sprinkle with fresh basil and serve.
