1. Prepare the Vegetables
Preheat your oven to 375°F (190°C).
Wash and chop all vegetables into bite-size pieces. Arrange them evenly in a large baking dish.
2. Lightly Roast the Vegetables
Place the vegetables in the oven for 10 minutes to slightly soften them. This helps release moisture and improves flavor.
3. Make the Creamy Cheese Sauce
In a saucepan over medium heat:
-
Melt butter.
-
Add flour and whisk for about 1 minute to create a roux.
-
Slowly pour in milk while whisking to prevent lumps.
-
Cook until the sauce thickens (3–4 minutes).
-
Add mozzarella, cheddar, salt, pepper, paprika, and Italian seasoning.
-
Stir until smooth and creamy.
4. Assemble the Casserole
Remove vegetables from the oven and pour the cheese sauce evenly over the vegetables.
5. Add Toppings
Sprinkle parmesan cheese and breadcrumbs on top for extra flavor and texture.
6. Bake
Bake for 20–25 minutes until the top becomes golden brown and bubbly.
7. Serve
Let the casserole rest for 5 minutes, then garnish with fresh parsley and serve warm.
