Ingredients

Scale

Vegetables

  • 2 cups mixed winter vegetables (diced carrots, parsnips, cauliflower, broccoli, or Brussels sprouts)

Casserole Filling

  • 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
  • 1/2 teaspoon dried thyme
  • 1/4 teaspoon garlic powder
  • Salt and freshly ground black pepper, to taste

Topping

  • 1/4 cup breadcrumbs, regular or panko style
  • 1 tablespoon melted butter

Instructions

  1. Prepare Oven and Baking Dish: Preheat the oven to 375°F (190°C). Lightly grease a medium baking dish with butter or oil to prevent sticking.
  2. Prep Vegetables: Steam or blanch fresh mixed winter vegetables for 3 to 4 minutes until just tender, then drain well. If using frozen vegetables, thaw completely and pat dry to remove any excess moisture. This ensures the casserole isn’t watery.
  3. Combine Filling Ingredients: In a large mixing bowl, combine the prepared vegetables with low-fat cream of mushroom soup, milk, shredded cheese, dried thyme, garlic powder, salt, and freshly ground black pepper. Mix thoroughly so the vegetables are evenly coated with the creamy mixture.
  4. Fill Baking Dish: Transfer the vegetable mixture into the prepared baking dish and spread it out evenly with a spoon or spatula.
  5. Add Topping: In a small bowl, mix the breadcrumbs with melted butter until well blended. Sprinkle this breadcrumb mixture evenly over the top of the casserole to create a crispy crust once baked.
  6. Bake: Place the casserole in the preheated oven and bake uncovered for 25 to 30 minutes, or until the topping turns golden brown and the filling is bubbling around the edges.
  7. Rest and Serve: Remove from the oven and let the casserole rest for 5 minutes before serving warm. This helps the flavors to settle and makes serving easier.

Notes

  • You can customize the vegetables based on what is available or preferred, but make sure to cut them into uniform pieces for even cooking.
  • Use panko breadcrumbs for a crunchier topping.
  • For a richer flavor, substitute the milk with half-and-half or cream, but this will increase the fat content.
  • This dish can be made ahead and refrigerated before baking; just add a few extra minutes to the baking time if cold from the fridge.
  • To make dairy-free, use plant-based milk and a dairy-free cheese alternative and confirm the soup is dairy-free.
