Step‑by‑Step Instructions for Creamy Vegetable Casserole

Step 1: Preheat the Oven
Begin by preheating your oven to 375°F (190°C). This initial step ensures that your creamy vegetable casserole bakes evenly, creating a golden and bubbly finish. Once preheated, make sure your oven rack is positioned in the center for optimal heat distribution, setting the stage for delicious layers of flavor to meld together.

Step 2: Sauté the Aromatics
In a large skillet, melt 2 tablespoons of butter over medium heat. Add 1 medium diced onion and sauté for about 5 minutes, or until it becomes translucent and fragrant. The softened onion serves as a perfect base for your creamy vegetable casserole. Stir occasionally to prevent sticking, ensuring an inviting aroma fills your kitchen.

Step 3: Cook the Mushrooms and Garlic
Next, add 2 minced garlic cloves and 1 cup of sliced mushrooms to the skillet. Cook for approximately 4 minutes until the mushrooms are tender and release their juices. This will enhance both the flavor and texture of the casserole, making it rich and satisfying. Stir well to combine the flavors, bringing a savory depth to your dish.

Step 4: Add the Vegetables
Stir in 2 cups of broccoli florets, 1 cup of cauliflower florets, 1 cup of sliced carrots, and 1 cup of frozen peas. Allow these colorful vegetables to cook for about 5-7 minutes, just until they soften slightly but still hold their shape. This step contributes vibrant flavors and nutrients to your creamy vegetable casserole, ensuring each bite is both delicious and healthy.

Step 5: Create the Creamy Base
In a mixing bowl, whisk together 1 can (10.5 oz) of cream of mushroom soup, 1 cup of milk, and ½ cup of sour cream until the mixture is smooth and well combined. This creamy base enrobe all your sautéed vegetables, enhancing the rich, comforting essence of the casserole. Get ready to bring all the elements together in the next step!

Step 6: Incorporate the Seasonings
Mix in 1 cup of shredded cheddar cheese, 1 teaspoon of salt, ½ teaspoon of black pepper, and 1 teaspoon of dried thyme. Stir the creamy mixture thoroughly until the cheese has melted into the sauce, creating a velvety texture that encapsulates the diverse flavors of your creamy vegetable casserole. It’s about to get even more delicious!

Step 7: Fold in the Vegetables
Carefully fold the sautéed vegetable mixture into the creamy sauce, ensuring all the veggies are well-coated. This process infuses your creamy vegetable casserole with rich, cheesy goodness that will satisfy any comfort food lover. Use a spatula to gently mix, preserving the shape and texture of the veggies as you go.

Step 8: Transfer to Baking Dish
Grease a 9×13-inch baking dish with a bit of butter or cooking spray. Pour the creamy vegetable casserole mixture into the dish, spreading it evenly. This generous layer of wholesome goodness sets the stage for a bubbling and flavorful bake. Make sure to smooth the top with a spatula for an even cook.

Step 9: Prepare the Topping
In a bowl, combine 1 cup of breadcrumbs and ¼ cup of grated Parmesan cheese. Sprinkle this mixture evenly over the top of the casserole. This topping adds a delightful crunch and enhances the overall flavor of your creamy vegetable casserole, promising a satisfying contrast to the creamy texture below.

Step 10: Bake to Perfection
Place the baking dish in the preheated oven and bake for 25–30 minutes. You’ll know it’s done when the topping is golden brown and the sauce is bubbling around the edges. This visually enticing result indicates that all the ingredients have melded beautifully, creating a mouthwatering creamy vegetable casserole.

Step 11: Rest Before Serving
Once out of the oven, let the creamy vegetable casserole rest for at least 10 minutes. This resting period allows the dish to set, making slicing much easier.
