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 the rinsed quinoa, reduce heat, cover, and let simmer for about 12–15 minutes until all the liquid is absorbed. Fluffing it with a fork afterward ensures that it stays light and airy.
Step 2: Sauté the Vegetables
In a large skillet, heat olive oil over medium heat. Add diced onion and minced garlic; cooking them until fragrant will enhance their natural sweetness. Then stir in bell pepper, zucchini, mushrooms, and cherry tomatoes. Cooking these veggies for about 5–7 minutes allows them to soften while retaining their vibrant colors.
Step 3: Incorporate Spinach and Seasonings
Add baby spinach to your sautéed mixture along with dried oregano, basil, smoked paprika, salt, and pepper. Stir until the spinach wilts down—it adds not just nutrition but also color to your casserole.
Step 4: Mix the Sauce
In a small bowl, combine tomato sauce, Greek yogurt, and red pepper flakes if desired. Mixing these ingredients creates a creamy sauce that binds everything together while adding depth of flavor.
Step 5: Combine Everything
Preheat your oven to 190°C (375°F). In a large mixing bowl, combine cooked quinoa, sautéed vegetables, and sauce. Stir everything until well-coated before transferring it all into a lightly greased baking dish (9×13 inches).
Step 6: Bake Until Golden
Sprinkle mozzarella cheese and Parmesan cheese evenly over the top of your casserole. Cover with foil and bake for about 20 minutes. Removing the foil for another 10 minutes allows that cheesy goodness to get bubbly and golden—a sight that’s sure to make anyone’s mouth water!
Step 7: Serve It Up!
After letting the casserole rest for about five minutes post-baking, garnish it with chopped fresh parsley or basil before diving in. Enjoy every cheesy bite of this delicious Veggie-Packed Quinoa Casserole!
Pro Tips for Making Veggie-Packed Quinoa Casserole
Creating a deliciously satisfying casserole is easy with a few handy tips!
-
Rinse Your Quinoa: Always rinse quinoa thoroughly before cooking. This removes the natural coating called saponin, which can give your dish a bitter taste.
-
Customize Your Veggies: Feel free to swap in seasonal vegetables or whatever you have on hand. This flexibility allows you to use fresh produce and keep your casserole exciting every time you make it!
-
Layer the Cheese: For an extra cheesy experience, consider mixing some cheese into the filling before topping it off. This will create delightful cheesy pockets throughout your casserole.
-
Don’t Overcook the Veggies: Sauté the vegetables just until they’re tender; they’ll continue cooking in the oven. This preserves their flavor and texture, making each bite delightful.
-
Let It Rest: Allowing the casserole to rest for a few minutes after baking helps it set, making it easier to serve and enhancing the flavors as they meld together.
