Ingredients

• 2 cups broccoli florets, chopped
• 2 cups cauliflower florets, chopped
• 1 large carrot, thinly sliced
• 1 medium zucchini, sliced
• 1 cup sliced mushrooms
• 1 small onion, finely chopped
• 2 cloves garlic, minced
• 1 cup cooked quinoa or rice (optional)
• 1 ½ cups shredded cheddar cheese (or vegan cheese)
• 1 cup milk (dairy or plant-based)
• 3 tablespoons all-purpose flour
• 3 tablespoons butter or olive oil
• 1 teaspoon dried thyme
• Salt and pepper to taste
• ½ cup breadcrumbs for topping
• 2 tablespoons fresh parsley, chopped (optional)

Equipment

• Baking dish (9×13 inch recommended)
• Large skillet or sauté pan
• Mixing bowls
• Measuring cups and spoons
• Wooden spoon or spatula
• Whisk
• Knife and cutting board
• Oven mitts

Instructions

1. Preheat your oven to 375°F (190°C). Lightly grease your baking dish with butter or oil to prevent sticking.
2. Sauté the aromatics: In a large skillet, heat butter or olive oil over medium heat. Add the chopped onion and garlic, cooking until translucent and fragrant, about 3-4 minutes.
3. Add the vegetables: Toss in the broccoli, cauliflower, carrot, zucchini, and mushrooms. Cook for 5-7 minutes, stirring occasionally, until vegetables begin to soften. Season with salt, pepper, and thyme.
4. Make the cheese sauce: In a separate saucepan, melt 3 tablespoons of butter over medium heat. Whisk in the flour and cook for 1 minute to form a roux. Gradually whisk in the milk, stirring constantly until the mixture thickens, about 3-5 minutes.
5. Combine cheese: Remove the sauce from heat and stir in 1 cup of shredded cheddar cheese until melted and smooth. Adjust seasoning with salt and pepper as needed.
6. Mix casserole layers: In a large bowl, combine the sautéed vegetables, cooked quinoa or rice (if using), and cheese sauce. Stir gently to combine.
7. Assemble the casserole: Pour the mixture into the prepared baking dish. Sprinkle the remaining ½ cup cheddar cheese evenly on top, followed by the breadcrumbs for a crunchy topping.
8. Bake: Place the casserole in the preheated oven and bake for 25-30 minutes, or until the top is golden brown and bubbling.
9. Garnish and serve: Remove from oven and let it cool for 5 minutes. Garnish with fresh parsley before serving.

Tips & Variations

To make this casserole gluten-free, substitute all-purpose flour with a gluten-free blend and use gluten-free breadcrumbs.

You can easily swap the vegetables depending on what’s in season. Try adding bell peppers, sweet potatoes, or spinach for a different flavor profile.

For a vegan version, substitute the cheese with your favorite plant-based cheese and use a non-dairy milk like almond or oat milk.

For extra protein, add cooked lentils, chickpeas, or diced tofu to the mix. If you prefer a creamier casserole, stir in a dollop of sour cream or Greek yogurt before baking.

Want a spicy kick? Add a pinch of crushed red pepper flakes or a dash of smoked paprika to the vegetable sauté.
