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

Directions

Step 1

Preheat your oven to 375°F (190°C). Grease a 9x13-inch baking dish lightly with olive oil or nonstick spray.

Step 2

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.

Step 3

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.

Step 4

Fold in the diced ham and 2 tablespoons of chopped green onions into the potato mixture.

Step 5

Spread the mixture evenly into the greased baking dish. Top with the remaining 1 cup of shredded cheddar cheese.

Step 6

In a small bowl, combine breadcrumbs with 1 tablespoon of olive oil. Sprinkle the breadcrumb mixture evenly over the top of the casserole.

Step 7

Bake in the preheated oven for 20–25 minutes, or until the casserole is heated through and the top is golden brown and bubbly.

Step 8

Garnish with the remaining tablespoon of chopped green onions before serving. Serve hot!
