Ingredients

  • 2 cups broccoli florets, chopped
  • 1 cup cauliflower florets, chopped
  • 1 large carrot, thinly sliced
  • 1 red bell pepper, diced
  • 1 zucchini, sliced
  • 1 cup cherry tomatoes, halved
  • 1 medium onion, finely chopped
  • 2 cloves garlic, minced
  • 1 cup cooked quinoa (or brown rice for variation)
  • 1 cup low-fat cottage cheese or plant-based ricotta for vegan option
  • 1/2 cup shredded mozzarella cheese or vegan cheese alternative
  • 1/4 cup grated Parmesan cheese (optional)
  • 1/2 cup low-sodium vegetable broth
  • 2 tablespoons olive oil
  • 1 teaspoon dried oregano
  • 1 teaspoon dried basil
  • Salt and freshly ground black pepper, to taste
  • Fresh parsley for garnish

Equipment

  • Large mixing bowl
  • Cutting board and sharp knife
  • Measuring cups and spoons
  • 9×13 inch baking dish
  • Medium skillet
  • Wooden spoon or spatula
  • Oven mitts
  • Aluminum foil (optional)

Instructions

  1. Preheat your oven to 375°F (190°C). Lightly grease your baking dish with olive oil or use cooking spray.
  2. Prepare the vegetables: Wash and chop the broccoli, cauliflower, carrot, bell pepper, zucchini, and cherry tomatoes. Finely chop the onion and mince the garlic.
  3. Sauté the aromatics: Heat 2 tablespoons of olive oil in a medium skillet over medium heat. Add the chopped onion and garlic, cooking until translucent and fragrant, about 3-4 minutes.
  4. Add the chopped vegetables (except cherry tomatoes) to the skillet. Sauté for 5-7 minutes until they start to soften but still maintain some crunch. Season with salt, pepper, dried oregano, and basil.
  5. Combine quinoa and cottage cheese: In a large mixing bowl, mix the cooked quinoa with cottage cheese (or plant-based ricotta). This creates a creamy base for the casserole.
  6. Add sautéed vegetables to the quinoa mixture and gently fold to combine. Stir in the cherry tomatoes and vegetable broth to moisten the mixture.
  7. Transfer the mixture to the prepared baking dish and spread evenly.
  8. Sprinkle the shredded mozzarella and Parmesan cheese on top for a golden, cheesy crust. For a vegan twist, use your favorite vegan cheese alternatives.
  9. Cover the casserole loosely with aluminum foil and bake for 25 minutes.
  10. Remove the foil and bake for an additional 10-15 minutes until the cheese is bubbly and lightly browned.
  11. Remove from oven and let cool for 5 minutes before serving.
  12. Garnish with fresh parsley and enjoy your healthy vegetable casserole!
