Prep and Cook Time
- Preparation: 15 minutes
- Cook Time: 40 minutes
- Total Time: 55 minutes
Yield
- Serves 6 hearty portions
Difficulty Level
- Easy – Perfect for weeknight meals or cozy weekend cooking
Ingredients
- 1 cup quinoa, rinsed thoroughly
- 2 cups low-sodium vegetable broth
- 1 medium sweet potato, peeled and diced (about 1 ½ cups)
- 1 cup fresh spinach, chopped
- 1 cup chopped mushrooms (cremini or button)
- 1 medium onion, finely chopped
- 2 cloves garlic, minced
- 1 cup low-fat Greek yogurt
- 1 large egg, lightly beaten
- ½ cup shredded sharp cheddar cheese
- 1 teaspoon dried thyme
- 1 teaspoon smoked paprika
- Salt and freshly ground black pepper to taste
- 2 tablespoons olive oil
Instructions
- Preheat your oven to 375°F (190°C). Grease a 9×13-inch casserole dish lightly with olive oil to prevent sticking.
- Cook the quinoa: In a medium saucepan, bring the vegetable broth to a boil. Add the quinoa, reduce heat to low, cover, and simmer for 15 minutes or until liquid is absorbed and quinoa is tender. Fluff with a fork and set aside.
- Sauté the vegetables: While quinoa cooks, heat olive oil in a skillet over medium heat. Add onion and garlic, sauté until translucent, about 3 minutes. Add mushrooms and sweet potatoes; cook until they begin to soften, about 7 minutes, stirring occasionally to prevent sticking.
- Season the sautéed veggies with thyme, smoked paprika, salt, and pepper. Stir in chopped spinach and cook until just wilted, around 2 minutes.
- Combine the wet ingredients: In a large bowl, whisk together Greek yogurt and beaten egg until smooth.
- Mix the casserole base: Add the cooked quinoa and sautéed veggies to the yogurt mixture. Stir well to combine all ingredients evenly.
- Transfer to casserole dish: Pour mixture into the prepared dish and spread evenly. Sprinkle the shredded cheddar cheese on top for a delightful golden crust.
- Bake uncovered: Place in the preheated oven and bake for 20-25 minutes or until the top is bubbly and golden brown.
- Rest before serving: Remove from oven and let rest for 5 minutes to allow flavors to meld and the casserole to set.
Chef’s Notes & Tips for Success
- For a vegan variation, substitute Greek yogurt and egg with silken tofu blended with lemon juice and nutritional yeast.
- Try swapping quinoa with brown rice or cauliflower rice for different textures and nutritional profiles.
- Make ahead by preparing the quinoa and sautéed vegetables in advance; assemble and refrigerate the casserole up to 24 hours before baking.
- If your casserole seems dry, stir in a splash of unsweetened almond milk or vegetable broth before baking.
- Use fresh herbs like rosemary or parsley instead of thyme to match your preference or seasonal availability.
Serving Suggestions
Present the casserole warm, garnished with freshly chopped parsley or scallions to uplift its earthy flavors and add a pop of color. Pair with a crisp garden salad drizzled with lemon vinaigrette for a balanced meal. This casserole also shines alongside roasted root vegetables or a simple bowl of steamed green beans for extra nutrients and texture. For an indulgent touch, drizzle a little extra virgin olive oil or a squeeze of fresh lemon juice just before serving to brighten every bite.

Effortless Preparation Tips for Stress-Free Cooking
To embrace stress-free cooking, prep key ingredients early-wash and dice vegetables, rinse quinoa, and preheat your oven ahead of time. A sharp knife and a sturdy cutting board make fast work of chopping, while using a non-stick skillet helps prevent sticking and burning. Organizing ingredients by their cooking times in separate bowls simplifies your workflow and keeps you focused. Minimal-cleanup essentials like parchment-lined casserole dishes or silicone mats can save precious time. Most importantly, trust your senses-tasting as you go and adjusting seasoning builds confidence and delivers delicious results.
Versatile Casserole Recipes for Every Dietary Need
The beauty of this casserole formula is its adaptability. For gluten-free needs, keep quinoa and omit breadcrumbs or flour-based binders. Vegetarians will enjoy the egg and cheese, while vegans can rely on plant-based yogurt alternatives and flax eggs. Those watching macros can swap sweet potatoes for butternut squash or packed greens for extra fiber and fewer carbs. The ingredients can be tailored to your pantry and palette, encouraging you to experiment with seasonal produce and protein sources like lentils, chickpeas, or shredded chicken for added heartiness.
Smart Storage and Reheating to Maximize Taste and Freshness
Store leftovers in airtight containers and refrigerate for up to 4 days to preserve flavor and texture. For longer storage, freeze individual portions wrapped tightly in plastic wrap then placed in freezer bags to prevent freezer burn. Thaw overnight in the refrigerator before reheating. To reheat, cover the casserole with foil and warm in a 350°F (175°C) oven for 15-20 minutes until heated through. A quick microwave steam with a damp paper towel or splash of broth also restores moisture and gives you a fast, tasty meal. Proper storage and gentle reheating keep this wholesome and simple casserole tasting fresh and inviting every time.

Lean proteins like chicken breast or beans also boost nutrition without extra fat.
Q4: Are there vegetarian or vegan casserole options that are still filling and nutritious?
