Recipe Information
Ingredients
- 2 cups instant mashed potato mix
- 4 cups water
- 1 cup milk
- 2 tablespoons unsalted butter
- 2 cups shredded cheddar cheese
- 2 cups cooked ham, diced
- 1 cup sour cream
- 3 tablespoons green onions, chopped
- 1 teaspoon garlic powder
- 0.5 teaspoon salt
- 0.5 teaspoon black pepper
- 0.5 cup breadcrumbs
- 1 tablespoon olive oil
Instructions
Preheat your oven to 375°F (190°C). Grease a 9x13-inch baking dish lightly with olive oil or nonstick spray.
In a medium saucepan, bring 4 cups of water to a boil. Remove from heat and stir in the instant mashed potato mix. Add the butter and milk, stirring until the potatoes are smooth and creamy. Set aside.
In a large mixing bowl, combine the mashed potatoes with sour cream, garlic powder, salt, black pepper, and 1 cup of shredded cheddar cheese. Mix until well combined.
Fold in the diced ham and 2 tablespoons of chopped green onions into the potato mixture.
Spread the mixture evenly into the greased baking dish. Top with the remaining 1 cup of shredded cheddar cheese.
In a small bowl, combine breadcrumbs with 1 tablespoon of olive oil. Sprinkle the breadcrumb mixture evenly over the top of the casserole.
Bake in the preheated oven for 20–25 minutes, or until the casserole is heated through and the top is golden brown and bubbly.
Garnish with the remaining tablespoon of chopped green onions before serving. Serve hot!
