Ingredients

• 2 cups cooked quinoa or brown rice
• 1 medium zucchini, diced
• 1 red bell pepper, chopped
• 1 cup fresh spinach, chopped
• 1 cup mushrooms, sliced
• 1 small onion, finely chopped
• 2 cloves garlic, minced
• 1 cup shredded mozzarella or vegan cheese
• 1 cup ricotta cheese or plant-based alternative
• 1 cup marinara sauce
• 1/2 cup grated Parmesan or nutritional yeast
• 2 tbsp olive oil
• 1 tsp dried oregano
• 1 tsp dried basil
• Salt and pepper to taste

Equipment

• Large mixing bowl
• Cutting board and knife
• Skillet or frying pan
• Measuring cups and spoons
• 9×13 inch casserole dish
• Oven
• Spatula or wooden spoon

Instructions

1. Preheat your oven to 375°F (190°C). Lightly grease your casserole dish with olive oil to prevent sticking.
2. Prepare the vegetables: Dice the zucchini, chop the bell pepper, slice the mushrooms, finely chop the onion, and mince the garlic.
3. Sauté the aromatics: In a skillet over medium heat, heat 2 tbsp olive oil. Add the onion and garlic, cooking until translucent and fragrant, about 3-4 minutes.
4. Add the vegetables: Toss in the zucchini, bell pepper, mushrooms, and spinach. Cook for 5-7 minutes until they soften, stirring occasionally. Season with salt, pepper, oregano, and basil.
5. Mix the base: In a large bowl, combine the cooked quinoa or brown rice with the sautéed vegetables and marinara sauce. Stir until everything is well incorporated.
6. Layer the casserole: Spread half of the quinoa-vegetable mixture in the bottom of your casserole dish. Dollop spoonfuls of ricotta cheese evenly over the layer. Then, add the remaining quinoa mixture on top.
7. Add the cheeses: Sprinkle shredded mozzarella and grated Parmesan evenly over the top layer.
8. Bake uncovered in the preheated oven for 25-30 minutes, or until the cheese is melted, bubbly, and golden brown on top.
9. Rest and serve: Remove from the oven and let the casserole rest for 5-10 minutes before serving. This helps the layers set and makes it easier to cut.

Tips & Variations

For a vegan version, substitute ricotta and mozzarella with plant-based cheese alternatives. Nutritional yeast adds a cheesy flavor and can replace Parmesan.

Try swapping quinoa for cooked lentils or chickpeas for extra protein and texture.

Add other vegetables like roasted sweet potatoes, eggplant, or kale to change up the flavor profile.

For an extra flavor boost, sprinkle fresh basil or parsley on top after baking. You can also drizzle a little balsamic glaze for a tangy finish.
