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 lightly grease a medium-sized baking dish with butter or cooking spray. Make sure you get the edges well, as this will help with easy serving later. The aroma of the melting butter will start to fill the kitchen, setting the stage for the delicious Creamy Winter Vegetable Casserole to come.
Step 2: Prep Vegetables
In a large pot, bring water to a boil and steam or blanch your mixed winter vegetables—carrots, parsnips, cauliflower, and Brussels sprouts—for about 3-4 minutes until they are tender but still vibrant in color. Drain them and pat dry if using frozen veggies. This step ensures that the vegetables retain their structure and vibrant flavors in your casserole.
Step 3: Combine Filling Ingredients
In a large mixing bowl, combine your prepared vegetables with cream of mushroom soup, whole or plant-based milk, and your choice of shredded cheddar or Gruyère cheese. Add in the dried thyme, garlic powder, salt, and pepper, mixing thoroughly until everything is well incorporated. The creamy mixture should have a lovely consistency, ready to envelop those delightful veggies.
Step 4: Fill Baking Dish
Transfer the combined vegetable mixture into your greased baking dish. Spread it evenly, making sure all the veggies are well-distributed and coated with the creamy sauce. At this stage, you should see a colorful array peeking through, promising a delicious bite in every spoonful of your Creamy Winter Vegetable Casserole.
Step 5: Add Topping
In a small bowl, mix the breadcrumbs with melted butter until they are evenly coated. Sprinkle this mixture generously over the top of the casserole, ensuring an even covering. The breadcrumbs will turn golden brown as they bake, adding a delightful crunch to the creamy filling below.
Step 6: Bake
Place the casserole in the preheated oven and bake uncovered for 25-30 minutes. Keep an eye on it; the topping should become golden and crispy while the filling bubbles lightly around the edges. The rich aroma wafting from the oven will make your kitchen feel extra cozy, capturing the spirit of winter comfort food.
Step 7: Rest and Serve
Once baked to perfection, remove the casserole from the oven and let it rest for about 5 minutes. This allows the flavors to meld beautifully and makes serving easier. Scoop out generous portions of your Creamy Winter Vegetable Casserole, and savor the blend of warm, creamy, and crunchy textures that will surely please everyone at the table.

Make Ahead Options
This Creamy Winter Vegetable Casserole is perfect for meal prep enthusiasts, allowing you to save valuable time on busy weeknights! You can prepare the entire casserole up to 24 hours in advance by assembling it completely and covering it tightly with plastic wrap. Just refrigerate until you’re ready to bake. If you prefer, you can also prep the mixed vegetables and combine them with the soup, milk, and cheese mixture so it’s ready to go! For maximum freshness, keep the breadcrumb topping separate until baking. When you're ready to serve, simply pop it in the oven, and enjoy restaurant-quality results with minimal effort, just as delicious as when freshly made!
