Step‑by‑Step Instructions for Creamy Winter Vegetable Casserole
Step 1: Prep Oven and Dish
Preheat your oven to 375°F (190°C) and lightly grease a medium-sized baking dish with cooking spray or butter to prevent sticking. This step is crucial for achieving that golden, bubbly finish on your creamy winter vegetable casserole while ensuring an easy cleanup afterward.
Step 2: Prep Vegetables
Steam or blanch your mixed winter vegetables for 3-4 minutes until they are just tender but still vibrant in color. If using frozen vegetables, ensure they’ve completely thawed and are drained well to avoid excess moisture in the casserole. This will help maintain the perfect creamy texture when baked.
Step 3: Combine Filling
In a large mixing bowl, combine the prepared vegetables with the cream of mushroom soup, milk, and half of the shredded cheese. Then, add dried thyme, garlic powder, salt, and pepper to taste. Mix until all ingredients are well coated and the creamy consistency is achieved, ensuring each vegetable is enveloped in the delicious mushroom sauce.
Step 4: Fill Dish
Transfer the vegetable mixture into your prepared baking dish, spreading it evenly with a spatula to create a consistent layer. This ensures that each bite of your creamy winter vegetable casserole is loaded with flavor. Aim for a smooth, even surface as you arrange the filling.
Step 5: Prepare Topping
In a separate small bowl, combine the breadcrumbs with melted butter or olive oil, mixing thoroughly until all crumbs are coated. This mixture is key for achieving a crispy, golden topping. Once well mixed, sprinkle it evenly over the assembled casserole for that crunchy finish.
Step 6: Bake
Place the casserole in the preheated oven and bake uncovered for about 25-30 minutes, or until the topping turns a beautiful golden brown and the filling is bubbling around the edges. The baking time may vary slightly depending on your oven, so keep an eye on it towards the end for perfect doneness.
Step 7: Rest
Once baked, remove the casserole from the oven and let it rest for about 5 minutes to allow the flavors to settle and the casserole to firm up slightly. This leisurely pause will make it easier to serve and enjoy the melty, creamy warmth of your creamy winter vegetable casserole.
