Ingredients
For the Base
- Quinoa: 1 cup, uncooked. The base of our casserole, quinoa is a complete protein and gluten-free grain, providing a nutty flavor and satisfying texture. We’ll cook it beforehand to ensure it’s perfectly tender in the final dish.
For the Vegetables
- Broccoli Florets: 2 cups, cut into small, bite-sized pieces. Broccoli adds a lovely earthy flavor and vibrant green color. It’s also packed with vitamins and fiber, making our casserole even healthier.
- Carrots: 1 cup, diced. Carrots bring sweetness and a pleasant crunch to the casserole. They are also rich in beta-carotene, which our bodies convert to Vitamin A.
- Bell Peppers: 1 cup, diced (use a mix of colors for visual appeal and varied flavor). Bell peppers offer a slightly sweet and slightly tangy taste along with a satisfying crisp-tender texture when baked. They are also excellent sources of Vitamin C.
- Onion: 1 medium, diced. Onion forms the aromatic foundation of many savory dishes. It adds depth of flavor and sweetness as it cooks down.
- Garlic: 2-3 cloves, minced. Garlic provides a pungent and savory kick that complements the vegetables and cheese beautifully.
For Binding & Flavor
- Vegetable Broth: 2 cups. Used to cook the quinoa and add moisture to the casserole; vegetable broth enhances the overall flavor and keeps everything from drying out.
- Milk (or Cream for extra richness): 1 cup. Milk or cream binds the casserole ingredients together and adds a creamy texture.
- Shredded Cheese: 2 cups (a mix of cheddar and mozzarella works wonderfully). Cheese is the star of any cheesy casserole!
- Parmesan Cheese: ¼ cup, grated. Parmesan adds salty depth; it also browns beautifully on top.
Additional Ingredients
- Butter or Olive Oil: 2 tablespoons. Used to sauté the vegetables; butter provides richer flavor while olive oil is healthier.
- All-Purpose Flour (or gluten-free alternative like cornstarch): 2 tablespoons. Used to create a light roux that helps thicken the sauce.
- Dried Herbs: 1 teaspoon each of dried oregano and dried thyme. These herbs add warm flavors that complement the vegetables and cheese.
- Salt and Black Pepper: To taste. Essential seasonings enhance all flavors in the casserole.
- Optional: Red Pepper Flakes: ¼ teaspoon (or more to taste). Adds subtle heat without overpowering the dish.
- Optional: Fresh Parsley or Chives: For garnish; fresh herbs contribute color and freshness.
