Ingredients

• 2 cups broccoli florets (fresh or frozen)
• 1 cup sliced mushrooms
• 1 cup diced bell peppers (any color)
• 1 medium onion, chopped
• 2 cloves garlic, minced
• 1 cup cooked quinoa or rice
• 1 can (15 oz) black beans, drained and rinsed
• 1 cup shredded cheddar cheese (or vegan cheese)
• 1/2 cup sour cream (or dairy-free alternative)
• 1/2 cup milk (dairy or plant-based)
• 1 tablespoon olive oil
• 1 teaspoon dried oregano
• 1 teaspoon smoked paprika
• Salt and pepper to taste
• 1/2 cup breadcrumbs for topping

Equipment

• Large skillet or frying pan
• Mixing bowl
• 9×13 inch baking dish
• Measuring cups and spoons
• Spatula or wooden spoon
• Oven mitts
• Aluminum foil (optional, for covering)

Instructions

1. Preheat your oven to 375°F (190°C) and lightly grease your baking dish with olive oil or non-stick spray.
2. Heat the olive oil in a large skillet over medium heat. Add the chopped onion and sauté for 3-4 minutes until translucent.
3. Add the minced garlic, mushrooms, and bell peppers. Cook for another 5 minutes until vegetables are tender.
4. Stir in the broccoli florets and cook for 2-3 minutes, allowing them to soften slightly.
5. Remove the skillet from heat and transfer the cooked vegetables into a large mixing bowl.
6. Add the cooked quinoa, black beans, sour cream, milk, oregano, smoked paprika, salt, and pepper to the bowl. Mix everything gently until well combined.
7. Fold in half of the shredded cheese to the mixture.
8. Pour the mixture into the prepared baking dish and spread evenly.
9. Sprinkle the remaining shredded cheese and breadcrumbs evenly over the top for a crispy, golden crust.
10. Bake uncovered in the preheated oven for 25-30 minutes, or until the top is golden brown and the casserole is heated through.
11. Remove from oven and let it cool for 5 minutes before serving.

Tips & Variations

For a vegan version, substitute the cheese with your favorite plant-based cheese and use coconut yogurt or cashew cream instead of sour cream.

Feel free to swap quinoa for brown rice, bulgur, or even pasta for different textures.

Adding a handful of chopped fresh herbs like parsley or basil just before serving adds a fresh burst of flavor.

Try incorporating other vegetables like zucchini, carrots, or spinach depending on what’s available.

Nutrition Facts

Serving Suggestions

Vegetarian casseroles are hearty enough to be served as a standalone main dish, but pairing them with a fresh, crisp side salad or steamed greens can balance the meal wonderfully.

For a cozy comfort food experience, serve alongside warm crusty bread or try our Vegan Bread Machine Recipe for Soft, Delicious Loaves. A dollop of tangy yogurt or a drizzle of our Vegan Bechamel Sauce Recipe for Creamy Pasta Dishes also pairs beautifully with the casserole.

Don’t forget a refreshing beverage like iced herbal tea or sparkling water with lemon to complete your meal.
