Step‑by‑Step Instructions for Creamy Winter Vegetable Casserole
Step 1: Prepare Oven and Dish
Preheat your oven to 375°F (190°C) and lightly grease a medium baking dish with butter or olive oil. This ensures that your delicious Creamy Winter Vegetable Casserole won’t stick while baking and helps create a beautiful golden crust on the edges.
Step 2: Prep Vegetables
Steam or blanch the mixed winter vegetables—like carrots, parsnips, and broccoli—for about 3-4 minutes until just tender. Drain well and pat dry to remove excess moisture. If using frozen vegetables, thaw them completely and ensure they’re well-drained.
Step 3: Combine Filling
In a large mixing bowl, combine the prepared vegetables with the cream of mushroom soup, milk, shredded cheese, dried thyme, garlic powder, salt, and pepper. Stir until all the ingredients are well-coated, ensuring that each bite of your casserole is bursting with flavor.
Step 4: Fill Baking Dish
Spread the creamy vegetable mixture evenly into the prepared baking dish. Use a spatula to smooth the top for even cooking—this Creamy Winter Vegetable Casserole needs to bake uniformly to achieve a velvety filling.
Step 5: Add Topping
In a separate bowl, mix the breadcrumbs with melted butter until moistened. Sprinkle this mixture generously over the top of the casserole, creating a crunchy and enticing layer that will contrast beautifully with the creamy filling.
Step 6: Bake
Place the baking dish in the preheated oven and bake uncovered for 25-30 minutes. Keep an eye on it; you’re looking for a golden-brown topping and bubbling edges, which indicate that the casserole is cooked through and ready to delight.
Step 7: Rest and Serve
Once baked, remove the casserole from the oven and let it rest for 5 minutes before serving. This brief resting period allows the flavors to meld and makes it easier to scoop out portions of the rich and creamy winter vegetable casserole for everyone to enjoy.
