How to Make Cheesy Hamburger Potato Casserole
-
Preheat oven to 350°F (175°C) and lightly grease a 9×13-inch baking dish.
-
Cook the ground beef: In a skillet over medium heat, cook the ground beef and onions until beef is browned and onions are soft. Drain excess grease. Season with garlic powder, salt, and pepper.
-
Prepare the sauce: In a separate bowl, whisk together the cream of mushroom soup and milk until smooth.
-
Assemble the casserole:
-
Layer half of the sliced potatoes in the bottom of the dish.
-
Spread half of the beef mixture over the potatoes.
-
Pour half of the soup mixture over the top.
-
Sprinkle with 1 cup of shredded cheese.
-
Repeat all layers.
-
-
Cover and bake: Cover the dish with foil and bake for 60 minutes.
-
Uncover and finish baking: Remove the foil and bake for an additional 15–20 minutes, until potatoes are tender and the cheese on top is bubbly and golden.
-
Serve: Let the casserole sit for 5–10 minutes before serving to help it set. Top with green onions or paprika if desired.
Tips for Best Results
-
Use a mandoline or sharp knife to get even, thin potato slices so they cook evenly.
-
For extra creaminess, stir in a few spoonfuls of sour cream or cream cheese into the soup mixture.
-
Prefer a crispy topping? Sprinkle buttered breadcrumbs or crushed crackers over the top before the final bake.
Variations to Try
-
Add veggies: Try layering in frozen corn, peas, or green beans.
-
Spice it up: Mix in diced green chilies or a dash of hot sauce for heat.
-
Swap proteins: Ground turkey or sausage work well as a substitute for beef.
-
Cheese variety: Use a mix of cheeses like mozzarella, Colby Jack, or pepper jack.
