Step‑by‑Step Instructions for Creamy Winter Vegetable Casserole
Step 1: Prepare Oven and Baking Dish
Preheat your oven to 375°F (190°C) while you prep your ingredients. Grease a medium-sized baking dish with butter or cooking spray to prevent sticking, ensuring it’s ready for your rich, creamy winter vegetable casserole. The anticipation of that warm dish filling the air is just around the corner!
Step 2: Prep Vegetables
Steam or blanch the mixed winter vegetables—like carrots, parsnips, cauliflower, and Brussels sprouts—for about 3-4 minutes until they are just tender. Drain them well to remove excess water, which could make your casserole watery. If using frozen vegetables, make sure they are thoroughly thawed and dried before proceeding.
Step 3: Combine Filling Ingredients
In a large mixing bowl, add your prepared vegetables along with the cream of mushroom soup, milk, and shredded cheese. Sprinkle in the dried thyme, garlic powder, salt, and pepper, then stir everything together until fully combined. Ensure that every bit of vegetable is coated in that luscious mixture, ready to provide comforting layers in your creamy winter vegetable casserole.
Step 4: Fill Baking Dish
Carefully spread the creamy vegetable mixture evenly into the greased baking dish, smoothing it out with a spatula. Make sure it’s evenly distributed to ensure consistent cooking. This will serve as the hearty base of your casserole, granting a delightful, creamy contrast to the crunchy top layer.
Step 5: Add Topping
In a separate bowl, combine the breadcrumbs with melted butter, mixing until they’re well coated. Evenly sprinkle this buttery breadcrumb mixture over the top of the casserole. This topping will transform as it bakes, creating a golden, crunchy layer that perfectly contrasts the creamy filling below.
Step 6: Bake
Place the baking dish in the preheated oven and bake uncovered for 25-30 minutes. Keep an eye on it; the casserole is ready when the topping is golden brown, and small bubbles of creamy goodness are visible around the edges. The delightful aroma will surely fill your kitchen with warmth!
Step 7: Rest and Serve
Once baked, remove your creamy winter vegetable casserole from the oven and let it rest for about 5 minutes. This step allows the flavors to meld beautifully and makes it easier to serve. Scoop out portions, letting each one reveal the creamy texture and comforting warmth that awaits inside.
