Ingredients

• 3 cups cooked leftovers (protein, vegetables, etc.)
• 2 cups cooked rice, pasta, or potatoes
• 1.5 cups shredded cheese (cheddar, mozzarella, or any preferred cheese)
• 1 can cream of mushroom soup (or equivalent creamy soup)
• 0.5 cups milk
• 0.5 teaspoons salt
• 0.25 teaspoons black pepper
• 0.5 teaspoons garlic powder
• 0.5 cups breadcrumbs
• 1 tablespoon olive oil or melted butter

Directions

Step 1

Preheat the oven to 375°F (190°C). Grease a 9x13-inch casserole dish with nonstick cooking spray or a small amount of olive oil.

Step 2

In a large mixing bowl, combine the cooked leftovers, cooked rice/pasta/potatoes, 1 cup of shredded cheese, cream of mushroom soup, and milk. Mix well to ensure everything is evenly coated.

Step 3

Season the mixture with salt, black pepper, and garlic powder. Taste and adjust seasonings as needed.

Step 4

Spread the mixture evenly into the prepared casserole dish, pressing gently to create an even layer.

Step 5

In a small bowl, toss breadcrumbs with olive oil or melted butter until lightly coated. Sprinkle the breadcrumb mixture evenly over the casserole.

Step 6

Top with the remaining 0.5 cups of shredded cheese for a golden, melted topping.

Step 7

Bake in the preheated oven for 25-30 minutes, or until the casserole is bubbly and the top is golden brown.

Step 8

Remove from the oven and let rest for 5 minutes before serving. Enjoy your transformed leftovers!
