📝 Instructions

10 steps
1

Preheat your oven to 375°F (190°C). Grease a medium-sized casserole dish and set it aside.

2

Clean and slice the mushrooms, bell peppers, and zucchini into thin, bite-sized pieces. Finely chop the onion and mince the garlic.

3

Heat 1 tablespoon of olive oil in a large skillet over medium-high heat. Add the mushrooms and cook for 5-6 minutes until they release their moisture and start to brown. Remove the mushrooms and set them aside.

4

In the same skillet, add the remaining 1 tablespoon of olive oil. Sauté the onion, garlic, bell peppers, and zucchini for 6-8 minutes, or until they are softened and slightly caramelized. Remove from heat.

5

In a medium saucepan, melt the butter over medium heat. Whisk in the flour and cook for 1 minute to eliminate the raw flour taste. Gradually pour in the milk, whisking constantly to avoid lumps.

6

Add the heavy cream, Parmesan cheese, salt, black pepper, thyme, and paprika to the sauce. Continue stirring as the sauce thickens (about 3-4 minutes). Remove the sauce from heat.

7

In a large mixing bowl, combine the cooked vegetables, mushrooms, and prepared sauce. Mix thoroughly and pour the mixture into the greased casserole dish.

8

In a small bowl, mix the breadcrumbs with shredded mozzarella cheese and chopped parsley. Sprinkle this topping evenly over the casserole.

9

Bake the casserole in the preheated oven for 25-30 minutes, or until the top is golden brown and the dish is bubbly around the edges.

10

Remove from the oven and let it cool for 5 minutes before serving. Garnish with additional parsley if desired. Enjoy!
