Instructions:
Step 1
Preheat the oven to 350°F (175°C).
Step 2
Peel (optional) and thinly slice the potatoes.
Step 3
Brown the ground beef and onion in a skillet over medium heat until the meat is cooked through and the onion is tender. Drain excess fat and season with salt and pepper.
Step 4
In a bowl, whisk together the sour cream, milk, and condensed soup until smooth.
Step 5
Grease a 9×13 inch baking dish.
Step 6
Arrange half of the sliced potatoes in the bottom of the dish.
Step 7
Layer half of the cooked ground beef over the potatoes.
Step 8
Pour half of the creamy sauce over the beef and potatoes.
Step 9
Repeat the layers with the remaining potatoes, beef, and sauce.
Step 10
Sprinkle shredded cheddar cheese over the top, and add a pinch of paprika or dried herbs for extra flavor, if desired.
Step 11
Cover the dish with aluminum foil and bake in the preheated oven for 1 hour.
Step 12
Remove the foil after 20 to 30 minutes to allow the potatoes to soften and the topping to become golden and bubbly.
Step 13
Let the casserole cool for a few minutes before slicing and serving.
