Ingredients

Scale
  • 2 tablespoons unsalted butter
  • 1/4 cup all-purpose flour
  • 2 cups whole milk
  • 1 teaspoon salt
  • 1/2 teaspoon black pepper
  • 1/4 teaspoon garlic powder
  • 1/4 teaspoon onion powder
  • 1 cup shredded sharp cheddar cheese, divided
  • 1/2 cup shredded Monterey Jack cheese
  • 1 (10.5 ounce) can cream of mushroom soup
  • 1 cup frozen mixed vegetables (broccoli, carrots, peas, corn)
  • 1 cup frozen cauliflower florets
  • 1/2 cup panko breadcrumbs

Instructions

  1. Preheat your oven to 375 degrees Fahrenheit. Lightly grease an 8×8 inch baking dish.
  2. Melt the butter in a medium saucepan over medium heat. Whisk in the flour and cook for one minute, stirring constantly to create a roux.
  3. Gradually whisk in the milk until the mixture is smooth. Continue cooking, stirring often, until the sauce thickens enough to coat the back of a spoon, about 5 to 7 minutes. Do not let it boil rapidly.
  4. Remove the saucepan from the heat. Stir in the salt, pepper, garlic powder, and onion powder.
  5. Stir in 3/4 cup of the cheddar cheese and all of the Monterey Jack cheese until melted and smooth. This creates your creamy cheese vegetable dish sauce.
  6. Stir in the cream of mushroom soup until fully combined.
  7. Gently fold in the frozen mixed vegetables and cauliflower florets into the cheese sauce.
  8. Pour the vegetable mixture into the prepared baking dish.
  9. In a small bowl, combine the remaining 1/4 cup of cheddar cheese with the panko breadcrumbs. Sprinkle this topping evenly over the casserole.
  10. Bake for 25 to 30 minutes, or until the casserole is bubbly around the edges and the topping is golden brown.
  11. Let the hearty vegetable casserole rest for 5 minutes before serving.

Notes

  • For a richer flavor, use fresh or frozen-then-thawed vegetables instead of frozen. Pat them dry before adding them to the sauce.
  • If you want an extra crispy topping, lightly toast the panko breadcrumbs in a dry skillet before mixing them with the cheese.
  • This recipe works well as a vegetarian casserole main dish or a family dinner side dish.
