Step‑by‑Step Instructions for Creamy Winter Vegetable Casserole
Step 1: Prep Oven and Dish
Begin by preheating your oven to 375°F (190°C). While the oven warms, lightly grease a medium-sized baking dish with butter or cooking spray to prevent sticking. This Creamy Winter Vegetable Casserole will need a well-prepared base, so make sure your dish is ready to go.
Step 2: Prepare Vegetables
Next, steam or blanch your mixed winter vegetables—such as carrots, parsnips, and Brussels sprouts—for about 3 to 4 minutes until they are just tender. You want them to maintain a slight crunch, ensuring they don’t overcook later in the casserole. Drain and set aside to cool slightly.
Step 3: Combine Filling Ingredients
In a large mixing bowl, combine the prepared vegetables with the low-fat cream of mushroom soup and your choice of milk. Add the shredded cheddar or Gruyère cheese, dried thyme, garlic powder, salt, and black pepper. Stir until everything is evenly coated in the creamy mixture, creating a colorful medley that will form the base of your casserole.
Step 4: Fill Baking Dish
Carefully spread the vegetable mixture into the greased baking dish, ensuring it is evenly distributed across the bottom. This allows for uniform cooking and ensures that every bite of your Creamy Winter Vegetable Casserole is bursting with flavor. Smooth the top with a spatula for even browning.
Step 5: Prepare Topping
In a small bowl, combine the breadcrumbs with the melted butter, mixing until the crumbs are well coated. This mixture will create a deliciously crispy topping for your casserole. Sprinkle the breadcrumb mixture generously over the vegetable filling, ensuring an even layer for that perfect crunch.
Step 6: Bake
Place your casserole in the preheated oven and bake uncovered for 25 to 30 minutes. You’ll know it’s ready when the topping is a lovely golden brown and the filling is bubbling around the edges, filling your kitchen with a comforting aroma.
Step 7: Rest and Serve
Once out of the oven, allow the Creamy Winter Vegetable Casserole to rest for about 5 minutes. This resting period helps the flavors meld and the casserole to set slightly, making it easier to serve. Scoop out portions and enjoy warm with a smile!

Creamy Winter Vegetable Casserole Recipe FAQs

Absolutely! You can use a wonderful mix of winter vegetables like carrots, parsnips, cauliflower, and Brussels sprouts. I recommend dicing them evenly for uniform cooking. If you’re in the mood for variety, feel free to swap in broccoli or even some root vegetables like sweet potatoes!
How should I store leftovers?
The more the merrier when it comes to leftovers! Store any remaining Creamy Winter Vegetable Casserole in an airtight container in the fridge for up to 4 days. To reheat, simply pop it back into the oven at 350°F (175°C) for about 20 minutes, or until it’s warmed through. This helps maintain its creamy texture.
Can I freeze this casserole?
Absolutely! To freeze, wrap the casserole tightly in plastic wrap, then cover it with aluminum foil. It will stay good for up to 3 months in the freezer.

What if I accidentally overcook the veggies?
Oh no! If your vegetables are overcooked and too soft, don’t worry too much. To remedy this, you can try blending the casserole mixture slightly to bring it together if it feels mushy.
