Step-by-Step Instructions
1 Prepare the Vegetables
Start by washing and cutting all your vegetables into bite-sized pieces. Bring a pot of water to a boil and blanch the broccoli for 2–3 minutes, then immediately drain it. This helps maintain its bright green color and tender texture.
2 Cook the Vegetable Base
In a large skillet, melt the butter over medium heat. Add the chopped onion and garlic, and sauté until soft and fragrant. Then add the carrot, bell peppers, and zucchini. Cook for about 5 minutes until slightly tender but not overcooked.
3 Make the Creamy Sauce
Sprinkle the flour over the vegetables and stir well to combine. Gradually pour in the milk while continuously stirring to avoid lumps. Then add the heavy cream and keep stirring until the mixture thickens into a smooth, creamy sauce.
Season with salt, black pepper, oregano, and parsley. The sauce should be rich, velvety, and well-balanced in flavor.
4 Assemble the Casserole
Preheat your oven to 180°C (350°F). Transfer the cooked vegetables into a baking dish. Add the blanched broccoli and cherry tomatoes, then pour the creamy sauce evenly over the top, making sure everything is well coated.
5 Add Cheese and Bake
Sprinkle mozzarella and cheddar cheese generously over the casserole. For extra flavor, add parmesan if desired.
Bake in the oven for 20–25 minutes, or until the cheese is fully melted, bubbly, and golden brown on top.

This baked vegetable casserole is more than just a simple dish—it’s a comfort food classic with a healthy twist. The creamy texture combined with roasted vegetables creates a satisfying bite every time.
