How to Make Veggie-Packed Quinoa Casserole
Step 1: Cook the Quinoa
In a medium saucepan, bring 2 cups of vegetable broth to a boil. Add 1 cup of rinsed quinoa, reduce heat, cover, and let simmer for about 12-15 minutes until all the liquid is absorbed. Fluff with a fork and set aside. Cooking quinoa this way ensures it’s light and fluffy, which makes it perfect for our casserole!
Step 2: 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. Cook for 5-7 minutes until softened. Add baby spinach along with oregano, basil, smoked paprika, salt, and pepper; stir until spinach wilts. Removing from heat at this stage helps preserve the vibrant colors and nutrients of your veggies.
Step 3: Mix the Sauce
In a small bowl, mix tomato sauce, Greek yogurt, and red pepper flakes (if using). Stir until well combined. This sauce adds creaminess while keeping everything nutritious – it’s truly what ties all these wonderful flavors together!
Step 4: Combine Everything
Preheat your oven to 190°C (375°F). In a large mixing bowl, combine cooked quinoa with sautéed vegetables and sauce. Stir until everything is evenly coated. Transfer this delightful mixture into a lightly greased baking dish (9×13 inches). Ensuring an even mix means every bite will be bursting with flavor.
Step 5: Top with Cheese
Sprinkle mozzarella cheese and Parmesan cheese evenly over the top. Cover with foil and bake for 20 minutes. Remove foil and bake for another 10 minutes until cheese is bubbly and slightly golden. This step gives our casserole that irresistible cheesy topping that everyone loves!
Step 6: Serve & Enjoy
Let your casserole rest for about 5 minutes before serving. Garnish with freshly chopped parsley or basil for that final touch of freshness! Enjoy every bite knowing you’ve created something healthy yet comforting.
Now you’re ready to dig into this delicious Veggie-Packed Quinoa Casserole! It’s sure to become one of your favorite go-to recipes too!
Pro Tips for Making Veggie-Packed Quinoa Casserole
