Ingredients

• 1 cup cauliflower florets
• 1 medium carrot, peeled and diced
• 1 cup zucchini, diced
• 1 small onion, finely chopped
• 2 cloves garlic, minced
• 1 cup cooked quinoa or brown rice
• 1 cup shredded cheddar cheese (or a plant-based alternative for vegan option)
• 1/2 cup sour cream or Greek yogurt (use vegan sour cream for dairy-free)
• 1/2 cup milk (dairy or plant-based)
• 2 tablespoons olive oil
• 1 teaspoon dried thyme
• 1/2 teaspoon smoked paprika
• Salt and freshly ground black pepper, to taste
• 1/2 cup breadcrumbs for topping (optional for extra crunch)
• Fresh parsley, chopped for garnish

Equipment

• Large mixing bowl
• Cutting board and sharp knife
• Measuring cups and spoons
• Medium saucepan (for cooking quinoa or rice)
• Large skillet
• 8×8 inch casserole dish
• Oven preheated to 375°F (190°C)
• Spatula or wooden spoon
• Grater (if shredding cheese yourself)

Instructions

1. Preheat your oven to 375°F (190°C) and lightly grease your casserole dish with olive oil or non-stick spray.
2. Cook your quinoa or brown rice according to package instructions. Set aside once done.
3. Prepare the vegetables: Chop the broccoli, cauliflower, carrot, zucchini, and onion into bite-sized pieces. Mince the garlic.
4. Sauté the onions and garlic in a large skillet with 2 tablespoons of olive oil over medium heat until fragrant and translucent, about 3-4 minutes.
5. Add the chopped carrots, broccoli, cauliflower, and zucchini to the skillet. Cook for another 5-7 minutes until veggies are just tender but still vibrant. Season with thyme, smoked paprika, salt, and pepper.
6. In a large mixing bowl, combine the sautéed vegetables, cooked quinoa, shredded cheese, sour cream, and milk. Stir gently until all ingredients are well incorporated and the mixture looks creamy and cohesive.
7. Transfer the mixture into the prepared casserole dish and spread evenly.
8. Sprinkle breadcrumbs and extra cheese on top for a golden, crispy crust if desired.
9. Bake uncovered in the preheated oven for 25-30 minutes or until the top is bubbly and golden brown.
10. Remove from oven and let cool slightly before serving. Garnish with fresh parsley for a pop of color and freshness.

Tips & Variations

“To keep this casserole vegan, swap out the cheese and sour cream for your favorite plant-based alternatives. Nutritional yeast also adds a lovely cheesy flavor without dairy.”

• Use seasonal veggies: Swap broccoli and cauliflower for asparagus, bell peppers, or green beans depending on what’s fresh.
• Add protein boost: Mix in cooked lentils, black beans, or chickpeas for extra heartiness.
• Spice it up: Add a pinch of cayenne or red pepper flakes for subtle heat.
• Make it gluten-free: Use gluten-free breadcrumbs or skip the topping entirely.
• Make ahead: Assemble the casserole a day in advance and refrigerate, then bake when ready to enjoy.
