Step‑by‑Step Instructions for Creamy Winter Vegetable Casserole
Step 1: Preheat the Oven
Begin by preheating your oven to 375°F (190°C). While it warms, lightly grease a medium baking dish with cooking spray or a bit of butter to prevent the creamy winter vegetable casserole from sticking during baking.
Step 2: Prepare the Vegetables
Next, steam or blanch your diced mixed winter vegetables for 3-4 minutes until they are just tender but still vibrant. If you’re using frozen veggies, ensure they are fully thawed and pat them dry. Drain the prepared vegetables well, allowing excess moisture to escape.
Step 3: Combine the Filling
In a large mixing bowl, combine the tender vegetables with a can of cream of mushroom soup, ½ cup of milk, ½ cup of your favorite shredded cheese, ½ teaspoon of dried thyme, and a pinch of garlic powder, salt, and pepper. Mix well until everything is evenly coated, creating a luscious filling for your casserole.
Step 4: Fill the Baking Dish
Gently transfer the creamy vegetable mixture into your greased baking dish, making sure to spread it out evenly. This will ensure that every scoop of your creamy winter vegetable casserole has an even distribution of those delicious flavors.
Step 5: Add the Crunchy Topping
In a small bowl, combine ¼ cup of breadcrumbs with 1 tablespoon of melted butter. Stir until the breadcrumbs are evenly coated and then sprinkle this mixture over the filling. This crunchy topping adds a delightful contrast to the creamy layers beneath.
Step 6: Bake the Casserole
Place your casserole in the preheated oven and bake uncovered for about 25-30 minutes. You’ll know it’s done when the topping turns a lovely golden brown and the filling is bubbling at the edges, filling your kitchen with inviting aromas.
Step 7: Rest and Serve
Once baked, remove the creamy winter vegetable casserole from the oven and let it rest for about 5 minutes before serving. This brief waiting period allows the flavors to settle, making each bite of this comforting dish even more enjoyable.

Expert Tips for Creamy Winter Vegetable Casserole
- Uniform Veggies: Dice your mixed winter vegetables evenly to ensure they cook at the same rate. This prevents some pieces from being undercooked while others are overdone.
