Flavor & Texture

You get a savory beef base seasoned with Worcestershire, garlic, and a touch of ketchup on top that caramelizes while baking. The mashed potato layer is rich and silky from sour cream, milk, and butter, then finished with bubbling cheddar and fresh green onion for a bright pop. Texturally the contrast is what makes this so comforting: a firm, flavorful meat layer under soft, creamy potatoes and a golden cheese crust. Every spoonful offers meaty depth, creamy smoothness, and a little tang from the ketchup and sour cream. The outcome is familiar, nostalgic, and easy to love.

Ingredients

• 1 1/2 pounds ground beef
• 1 onion, finely chopped

• 1/2 teaspoon freshly ground black pepper
• 1/2 cup ketchup
• 2 pounds potatoes, peeled and sliced

Step by Step Instructions

Tips & Tricks for Success

Let the meat mixture be well combined but do not overwork it to keep the texture tender. Drain any excess water from the potatoes thoroughly before mashing so the topping stays fluffy rather than watery. Use a fork or spatula to smooth the mashed potato layer so the cheese browns evenly. If you prefer a deeper flavor, stir a little Dijon or smoked paprika into the potatoes. For prettier slices, let the casserole rest the full 10 minutes before cutting.

Storage & Make Ahead Tips

This casserole can be assembled a few hours ahead and chilled until ready to bake. Store leftovers in an airtight container in the refrigerator for up to four days. To freeze, bake first, cool completely, then wrap tightly and freeze for up to two months. Reheat in a low oven until warmed through to keep the topping creamy.

This is the kind of dish that makes homes feel like home: easy to prepare, full of comforting flavors, and generous enough to feed a crowd.
