Step‑by‑Step Instructions for Creamy Winter Vegetable Casserole
Step 1: Prepare Oven
Preheat your oven to 375°F (190°C). While the oven heats up, grab a medium baking dish and lightly grease it with cooking spray or a little olive oil. This ensures the creamy winter vegetable casserole won’t stick and will come out perfectly golden when it’s done baking.
Step 2: Prep Vegetables
Gather your mixed winter vegetables, such as carrots, parsnips, cauliflower, and broccoli, and steam or blanch them in boiling water for 3-4 minutes. The goal is to make them tender but still vibrant in color. After cooking, drain and set them aside to cool slightly while you combine the other ingredients.
Step 3: Combine Ingredients
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. Mix well until every piece of vegetable is evenly coated with the creamy mixture. This step helps bind all the flavors for your creamy winter vegetable casserole.
Step 4: Fill Dish
Transfer the vegetable and sauce mixture into the greased baking dish, spreading it evenly with a spatula. Make sure to level it out so that it cooks uniformly. The anticipation builds as the rich aroma of the cream and vegetables begins to fill your kitchen.
Step 5: Add Topping
In a small bowl, combine the breadcrumbs with melted butter, ensuring they are well-coated. Sprinkle the breadcrumb mixture evenly over the top of the vegetable casserole. This will create a deliciously crunchy layer that contrasts beautifully with the creamy filling underneath.
Step 6: Bake
Place the filled dish in the preheated oven and bake uncovered for 25-30 minutes. Keep an eye on it; you’ll know it’s ready when the topping is golden brown and the casserole filling is bubbling. The tantalizing scent will have everyone eagerly awaiting the first bite.
Step 7: Rest and Serve
Once baked, remove the casserole from the oven and let it rest for about 5 minutes. This cooling period allows the flavors to meld beautifully. Serve warm and enjoy the heartwarming comfort of your creamy winter vegetable casserole, a dish sure to impress everyone at your table.
