Creamy Winter Vegetable Casserole Recipe
Introduction
This creamy winter vegetable casserole is a comforting and flavorful dish perfect for chilly days. Packed with tender mixed vegetables and a cheesy mushroom sauce, it’s an easy way to enjoy seasonal produce in a warm, satisfying meal.

Ingredients
- 2 cups mixed winter vegetables (diced carrots, parsnips, cauliflower, broccoli, or Brussels sprouts)
- 1 can (10.5 oz) low-fat cream of mushroom soup
- 1/2 cup whole milk or unsweetened plant-based milk
- 1/2 cup shredded cheddar or Gruyère cheese
- 1/4 cup breadcrumbs (regular or panko style)
- 1 tablespoon melted butter
- 1/2 teaspoon dried thyme
- 1/4 teaspoon garlic powder
- Salt and freshly ground black pepper, to taste
Instructions
- Step 1: Preheat your oven to 375°F. Lightly grease a medium baking dish with butter or oil to prevent sticking.
- Step 2: Steam or blanch fresh vegetables for 3 to 4 minutes until just tender, then drain thoroughly. If using frozen vegetables, thaw fully and pat dry to remove excess moisture.
- Step 3: In a large bowl, combine the prepared vegetables, cream of mushroom soup, milk, shredded cheese, dried thyme, garlic powder, salt, and pepper. Stir well so all ingredients are evenly mixed and coated.
- Step 4: Transfer the vegetable mixture to the greased baking dish, spreading it out evenly with a spoon or spatula.
- Step 5: In a small bowl, mix the breadcrumbs with melted butter until combined. Sprinkle this mixture evenly over the top of the casserole.
- Step 6: Bake uncovered for 25 to 30 minutes, until the topping is golden brown and the filling is bubbling around the edges.
- Step 7: Remove from oven and let the casserole rest for 5 minutes before serving warm.
Tips & Variations
- For extra flavor, add a handful of cooked diced onions or shallots to the vegetable mixture before baking.
- You can substitute the cream of mushroom soup with homemade white sauce for a fresher taste.
- Try topping with crushed nuts or seeds mixed with breadcrumbs for added crunch.
- Use plant-based cheese and milk alternatives to make this casserole vegan-friendly.
Storage
Store any leftover casserole in an airtight container in the refrigerator for up to 3 days. Reheat covered in the oven at 350°F until warmed through, or microwave in shorter intervals to avoid drying out the dish.
