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.
Step 2: Sauté the Vegetables
In a large skillet over medium heat, heat 1 tablespoon of olive oil. Add diced onion and minced garlic; cook 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. Remove from heat.
Step 3: Prepare the Sauce
In a small bowl, mix together tomato sauce, Greek yogurt, and red pepper flakes (if using). Stir until well combined.
Step 4: Combine Ingredients
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 mixture into a lightly greased baking dish (9×13 inches).
Step 5: Bake
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.
Step 6: Serve
Let the casserole rest for about 5 minutes before serving. Garnish with chopped fresh parsley or basil before enjoying!

How to Perfect Veggie-Packed Quinoa Casserole
To ensure your Veggie-Packed Quinoa Casserole turns out perfectly every time, follow these helpful tips.
- Use rinsed quinoa – Rinsing quinoa removes its natural coating, called saponin, which can make it taste bitter. This step enhances the flavor of your casserole.
- Choose vibrant veggies – Opt for a mix of colorful vegetables like bell peppers and zucchini for both nutrition and visual appeal. The more colors you include, the better!
- Adjust seasoning – Feel free to tweak herbs and spices based on your personal preferences. Adding garlic powder or Italian seasoning can elevate the flavor even more.
- Don’t skip resting time – Letting the casserole rest for 5 minutes before serving allows it to set and makes it easier to cut into portions without falling apart.

Common Mistakes to Avoid
When preparing your Veggie-Packed Quinoa Casserole, it’s easy to make a few common mistakes. Here are some tips to help you avoid them.
- Skipping the rinsing of quinoa: Rinsing quinoa removes its natural coating, called saponin, which can impart a bitter taste. Always rinse quinoa under cold water before cooking.
- Overcooking vegetables: If you cook your vegetables for too long, they can become mushy and lose their vibrant colors. Sauté them just until softened to retain their texture and nutrients.
- Not seasoning adequately: A bland casserole is disappointing. Make sure to season your dish with salt, pepper, and herbs throughout the cooking process for maximum flavor.
- Using the wrong baking dish size: A dish that is too small may overflow while baking, while one that is too large may dry the casserole out. Use a 9×13 inch baking dish for best results.
- Forgetting about leftovers: This casserole is great for meal prep! Make sure to store leftovers properly to enjoy your meal later without losing quality.
