Base
- 1 cup quinoa, rinsed and drained
- 2 cups vegetable broth
Vegetables
- 1 tablespoon olive oil
- 1 small onion, diced
- 2 cloves garlic, minced
- 1 bell pepper (red or yellow), diced
- 1 zucchini, diced
- 1 cup cherry tomatoes, halved
- 1 cup baby spinach, chopped
- 1 cup mushrooms, sliced
- 1 teaspoon dried oregano
- 1 teaspoon dried basil
- 1⁄2 teaspoon smoked paprika
- Salt and pepper to taste
Sauce
- 1 cup tomato sauce
- 1⁄2 cup Greek yogurt (or sour cream)
- 1⁄2 teaspoon red pepper flakes (optional)
Toppings
- 1 cup shredded mozzarella cheese
- 1⁄4 cup grated Parmesan cheese
- 1⁄4 cup fresh parsley or basil, chopped (for garnish)
- Cook the Quinoa: In a medium saucepan, bring 2 cups of vegetable broth to a boil. Add 1 cup of rinsed quinoa, reduce heat to low, cover, and let simmer for about 12-15 minutes, until all the liquid is absorbed. Fluff the quinoa with a fork and set aside to cool slightly.
- Sauté the Vegetables: In a large skillet, heat 1 tablespoon of olive oil over medium heat. Add diced onion and minced garlic, cooking until fragrant, about 2 minutes. Stir in bell pepper, zucchini, mushrooms, and cherry tomatoes and cook for 5-7 minutes until softened. Add chopped baby spinach, then season with dried oregano, basil, smoked paprika, salt, and pepper. Stir until the spinach wilts, then remove from heat.
- Make the Sauce: In a small bowl, combine 1 cup tomato sauce with 1/2 cup Greek yogurt and 1/2 teaspoon red pepper flakes if using. Mix well until smooth.
- Assemble the Casserole: Preheat your oven to 190°C (375°F). In a large mixing bowl, combine the cooked quinoa, sautéed vegetables, and sauce. Stir thoroughly until everything is evenly coated. Transfer the mixture to a lightly greased 9×13 inch baking dish and spread it out evenly.
- Add Cheese & Bake: Sprinkle 1 cup shredded mozzarella cheese and 1/4 cup grated Parmesan cheese evenly over the top of the casserole. Cover the dish with foil and bake for 20 minutes. Remove the foil and bake for an additional 10 minutes until the cheese is bubbly and slightly golden brown.
- Rest & Serve: Remove the casserole from the oven and let it rest for 5 minutes before serving. Garnish with 1/4 cup chopped fresh parsley or basil for a fresh touch. Serve warm and enjoy!
