Instructions
 

Preparation

  • In a medium saucepan, bring 2 cups of vegetable broth to a boil. Add 1 cup of rinsed quinoa, reduce heat, cover, and let it simmer for 12-15 minutes, or until all the liquid has been absorbed. Fluff the cooked quinoa and set it aside to cool slightly.
  • While the quinoa is cooking, heat 1 tablespoon of olive oil in a large skillet over medium heat. Add the diced onion and minced garlic, sautéing for about 2 minutes until fragrant.
  • Add the diced bell pepper, zucchini, sliced mushrooms, and halved cherry tomatoes to the skillet. Cook for 5-7 minutes, stirring occasionally, until the vegetables are softened.
  • Include the chopped baby spinach and season with oregano, basil, smoked paprika, salt, and pepper. Stir until spinach wilts and everything is well combined. Remove from heat.

Baking

  • Preheat your oven to 190°C (375°F). In a large mixing bowl, combine the cooked quinoa, sautéed vegetables, and tomato sauce mixed with Greek yogurt and red pepper flakes, stirring until everything is evenly coated.
  • Transfer the combined mixture into a lightly greased baking dish (9x13 inches). Sprinkle shredded mozzarella cheese and grated Parmesan evenly over the top.
  • Cover with foil and bake for 20 minutes. Remove the foil and continue baking for another 10 minutes, or until the cheese is bubbly and golden.
  • Let the casserole rest for about 5 minutes before serving. Garnish with chopped fresh parsley or basil.

Notes

To elevate the casserole, add a splash of lemon juice or zest, experiment with seasonal vegetables, mix in beans for added protein, or add chunks of cooked chicken or turkey for a meatier version.
