Veggie-Packed Quinoa Casserole Ingredients
For the Casserole
• Quinoa – This gluten-free grain is the star of the dish, offering a nutty flavor and fluffy texture.
• Vegetable Broth – Use this for cooking quinoa; it adds a rich depth of flavor. Water can be substituted in a pinch.
• Olive Oil – Perfect for sautéing vegetables, it brings healthy fats to the mix.
• Onion – Adds aromatic sweetness when sautéed, enhancing the flavor profile.
• Garlic – Fresh garlic is best for maximum potency; it elevates all the other ingredients.
• Bell Pepper – Use either red or yellow for a cheerful crunch and vibrant color.
• Zucchini – Offers moisture and a mild flavor; swap for yellow squash if desired.
• Cherry Tomatoes – Their natural sweetness bursts with flavor; whole tomatoes can be chopped as an alternative.

Step‑by‑Step Instructions for Veggie-Packed Quinoa Casserole
Step 1: Cook the Quinoa
Begin by bringing 2 cups of vegetable broth to a boil in a medium pot. Once boiling, add 1 cup of rinsed quinoa, reduce the heat to low, cover, and let it simmer for 12-15 minutes. You’ll know it’s ready when the liquid is absorbed and the quinoa is fluffy. Remove it from heat and fluff with a fork, setting it aside for later.
Step 2: Sauté the Vegetables
In a large skillet, heat 2 tablespoons of olive oil over medium heat. Add 1 chopped onion and 3 minced garlic cloves, cooking for 2-3 minutes until they become fragrant and translucent. Stir in 1 chopped bell pepper, 1 diced zucchini, and 1 cup of sliced mushrooms. Cook the mixture for 5-7 minutes until the vegetables soften. Finally, throw in 1 cup of halved cherry tomatoes and 2 cups of baby spinach, cooking until the spinach wilts.
Step 3: Prepare the Sauce
In a separate bowl, combine 1 cup of tomato sauce, ½ cup of Greek yogurt, and a pinch of red pepper flakes (if using). Whisk together until smooth and creamy. This mixture will serve as the luscious sauce for your Veggie-Packed Quinoa Casserole, adding tanginess and depth to the dish.
Step 4: Preheat the Oven
While you’re preparing the casserole, preheat your oven to 190°C (375°F). This ensures that it’s hot enough when you’re ready to bake the casserole, allowing for that beautiful bubbly, golden top.
Step 5: Combine the Ingredients
In a large bowl, mix the cooked quinoa with the sautéed vegetable mixture. Pour the creamy sauce over the mixture and gently stir until everything is evenly coated. Transfer this delightful mix into a greased 9×13-inch baking dish, spreading it out evenly for consistent baking.
Step 6: Top with Cheese
Sprinkle 1 cup of shredded mozzarella cheese and ¼ cup of grated Parmesan cheese generously over the top of the casserole. This will create a deliciously gooey crust as it bakes. Cover the dish with aluminum foil to keep the moisture in, which helps the casserole mix cook evenly.
Step 7: Bake to Perfection
Place the prepared casserole in your preheated oven and bake it covered for 20 minutes. After that, carefully remove the foil and bake uncovered for an additional 10 minutes, or until the cheese is bubbly and golden brown. Keep an eye on it during the last few minutes to prevent burning.
Step 8: Rest and Garnish
Once out of the oven, allow the Veggie-Packed Quinoa Casserole to rest for about 5 minutes. This resting period helps the flavors meld beautifully. Before serving, garnish with freshly chopped parsley or basil to add a pop of color and flavor.

Veggie-Packed Quinoa Casserole Recipe FAQs
What’s the best way to select quinoa?
Absolutely! Choose quinoa that is organic and certified gluten-free for the best results. Look for seeds that are small and shiny without any dark spots, as those may indicate spoilage. Always rinse your quinoa under cold water before cooking to remove the natural saponins, which can impart a bitter flavor.
How should I store leftovers?
After letting your Veggie-Packed Quinoa Casserole cool completely, store any leftovers in an airtight container in the refrigerator for up to 3 days. Keeping it sealed will maintain its freshness and flavor. Reheat in the oven for about 20 minutes or in the microwave, covered, until warmed through.
Can I freeze the casserole?
Certainly! To freeze your Veggie-Packed Quinoa Casserole, prepare it up to the baking step, then cover tightly with aluminum foil or plastic wrap and freeze for up to 3 months. When you’re ready to enjoy it, thaw in the refrigerator overnight, then bake for about 30-40 minutes at 190°C (375°F) until bubbly. This makes for a perfect make-ahead meal!
What if my casserole turns out too watery?
No worries! If your casserole is too watery, it could be due to excess moisture from the vegetables or not enough cooking time for the quinoa. When assembling, ensure your veggies are well-drained. If you find it too moist after baking, simply place it back in the oven uncovered for an additional 10-15 minutes to allow excess liquid to evaporate.
Is this recipe suitable for my family with dietary restrictions?
Very! This Veggie-Packed Quinoa Casserole is inherently gluten-free and vegetarian. For dairy-free diets, simply substitute Greek yogurt and cheese with dairy-free alternatives. Always check labels for hidden allergens, and feel free to swap in favorite vegetables to suit your family’s taste preferences or needs.
How do I adjust the spiciness level?
You can easily control the heat in your casserole! Omit the red pepper flakes entirely for a milder flavor or add them to taste. If you enjoy more heat, consider adding diced jalapeños or a splash of hot sauce to the vegetable sauté. The more the merrier in customizing to your family’s spice tolerance!
