HOW TO MAKE CREAMY VEGETABLE CASSEROLE

Let’s walk through how to bring this dreamy casserole to life. From stovetop preparations to oven-baked goodness, each step builds layers of flavor and texture, culminating in a heartwarming dish that’s bound to become a family favorite.

1. Preheat your oven to 375°F (190°C) to ensure it reaches the perfect temperature while you assemble the ingredients.

2. In a large skillet, melt the butter over medium heat. Add the diced onion and cook until translucent, about 5 minutes, stirring occasionally to prevent browning.

3. Stir in the minced garlic and sliced mushrooms, cooking for approximately 4 minutes until the mushrooms are tender and fragrant.

4. Add the broccoli florets, cauliflower florets, sliced carrots, and frozen peas to the skillet. Cook for 5–7 minutes, stirring gently until the vegetables begin to soften while retaining a slight snap.

5. In a separate large mixing bowl, combine the cream of mushroom soup, milk, and sour cream. Whisk vigorously until the mixture is completely smooth and creamy.

6. Stir in the shredded cheddar cheese, salt, black pepper, and dried thyme. Mix well to distribute the seasonings evenly throughout the sauce.

7. Add the cooked vegetables from the skillet into the soup and cheese mixture. Stir until every piece of vegetable is thoroughly coated in the luscious sauce.

8. Pour the entire mixture into a greased 9×13-inch baking dish, spreading it into an even layer.

9. In a small bowl, combine the bread crumbs and grated Parmesan cheese. Sprinkle this topping evenly over the surface of the casserole for a crunchy, golden finish.

10. Place the casserole in the preheated oven and bake for 25–30 minutes, or until the top turns golden brown and bubbles appear around the edges.

11. After removing from the oven, allow the casserole to cool for a few minutes before serving, letting the sauce set slightly for perfect slicing.
