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 it warms, grab a medium-sized baking dish and generously grease it with butter or a non-stick spray to prevent your creamy winter vegetable casserole from sticking. This initial step sets the foundation for a perfectly baked dish that will come together beautifully.
Step 2: Prep Vegetables
Next, steam or blanch your mixed winter vegetables—like carrots, parsnips, and Brussels sprouts—for about 3-4 minutes. You want them to be just tender, offering a great texture for the casserole. After draining well, let the vegetables cool slightly before combining them with the other ingredients, ensuring a creamy, cohesive blend.
Step 3: Combine Filling Ingredients
In a large mixing bowl, combine the steamed vegetables with the creamy mushroom soup, whole milk or plant-based alternative, cheese, dried thyme, garlic powder, salt, and black pepper. Stir everything gently until the vegetables are evenly coated in the luscious sauce. This mixture creates the heart of your creamy winter vegetable casserole, full of flavor and warmth.
Step 4: Fill Baking Dish
Transfer the vegetable mixture into your prepared baking dish, spreading it out evenly with a spatula. Take a moment to admire how vibrant the mix looks—those colorful veggies nestled into a creamy base are sure to bring smiles to the dinner table. Make sure it’s evenly distributed for consistent cooking results.
Step 5: Add Topping
In a small bowl, combine breadcrumbs with melted butter, mixing until the crumbs are well-coated. Sprinkle this buttery breadcrumb mixture generously over the top of the casserole, creating a satisfying crunch that will contrast beautifully with the creamy filling beneath. This topping is key to achieving a delightful texture.
Step 6: Bake
Slide the baking dish into your preheated oven and bake uncovered for 25-30 minutes. Keep an eye on it; you’re looking for the topping to turn a golden brown and for bubbling to appear around the edges of the casserole. This visual cue indicates that it’s nearly ready to be devoured!
Step 7: Rest and Serve
Once golden and bubbling, remove your creamy winter vegetable casserole from the oven and allow it to rest for about 5 minutes. This short resting time helps the casserole set up a bit, making it easier to serve. Spoon out generous portions and enjoy the creamy, hearty goodness with family and friends!

How to Store and Freeze Creamy Winter Vegetable Casserole
