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 your rinsed quinoa, reduce heat, cover, and let simmer for about 12–15 minutes until all the liquid is absorbed. Fluffing it with a fork after cooking gives it that perfect light texture!
Step 2: Sauté the Vegetables
In a large skillet, heat your olive oil over medium heat. Add in the diced onion and minced garlic; cooking them until fragrant (about 2 minutes) brings out their natural sweetness. Stir in your bell pepper, zucchini, mushrooms, and cherry tomatoes. Cook everything for about 5–7 minutes until they soften. Adding baby spinach last gives it just enough time to wilt down while mixing in those delightful herbs.
Step 3: Prepare the Sauce
In a small bowl, combine tomato sauce, Greek yogurt, and red pepper flakes (if you want some spice). Mixing these together creates a creamy sauce that binds everything nicely without overpowering those fresh veggie flavors.
Step 4: Combine Ingredients
Preheat your oven to 190°C (375°F). In a large mixing bowl, combine cooked quinoa with your sautéed vegetables and sauce. Stir until everything is evenly coated—this step ensures every bite will be packed with flavor!
Step 5: Bake Your Casserole
Transfer your mixture into a lightly greased baking dish (9×13 inches). Sprinkle mozzarella cheese and Parmesan cheese evenly over the top. Cover with foil and bake for about 20 minutes; then remove the foil and bake for another 10 minutes until that lovely cheese is bubbly and slightly golden.
Step 6: Serve Up & Enjoy!
Once out of the oven, let your casserole rest for about five minutes before serving. Garnish with freshly chopped parsley or basil for that beautiful finishing touch! Enjoy each bite of this delightful Veggie-Packed Quinoa Casserole!
Pro Tips for Making Veggie-Packed Quinoa Casserole
Making the perfect Veggie-Packed Quinoa Casserole is simple with a few handy tips to enhance flavor and texture!
- Rinse your quinoa: This step removes the natural coating called saponin, which can impart a bitter taste. Rinsing ensures that your quinoa has a clean, nutty flavor.
- Customize your veggies: Feel free to swap in your favorite seasonal vegetables or whatever you have on hand! This not only makes the casserole more personal but also adds variety and nutrition.
- Use fresh herbs: Fresh parsley or basil as a garnish can elevate the dish’s flavor profile significantly. Fresh herbs provide brightness that complements the richness of the cheese and sauce.
- Let it rest before serving: Allowing the casserole to sit for about 5 minutes after baking helps it set up better, making it easier to portion out and serve without falling apart.
- Make it ahead of time: Prepare the casserole in advance, cover, and refrigerate it. When you’re ready to eat, simply pop it in the oven—this is especially handy for busy weeknights!
