Ingredients
Scale
1.5 lbs ground beef
1 medium onion, chopped
1 (10.5 oz) can condensed cream of mushroom soup (or homemade sauce)
1/2 cup milk
1 teaspoon dried thyme
1/2 teaspoon garlic powder
Salt and black pepper to taste
4 medium potatoes, peeled and thinly sliced (about 1/8 inch thick)
2 cups shredded cheddar cheese
Instructions
Preheat your oven to 375 degrees Fahrenheit. Lightly grease a 9×13 inch baking dish.
Brown the ground beef in a large skillet over medium heat. Drain off any excess fat.
Add the chopped onion to the skillet with the beef and cook until softened, about 5 minutes.
In a bowl, mix the condensed soup, milk, thyme, garlic powder, salt, and pepper. Stir this mixture into the ground beef and onion until combined.
Arrange half of the thinly sliced potatoes in an even layer in the bottom of the prepared baking dish.
Spread the entire ground beef mixture evenly over the layer of potatoes.
Top the beef layer with the remaining potatoes.
Pour any remaining sauce mixture evenly over the top layer of potatoes.
Cover the baking dish tightly with aluminum foil.
Bake for 45 minutes.
Remove the foil. Sprinkle the shredded cheddar cheese evenly over the top.
Return the casserole to the oven, uncovered, and bake for another 15 to 20 minutes, or until the potatoes are tender and the cheese is melted and bubbly.
Let the casserole rest for 10 minutes before serving.
Notes
For a from-scratch sauce instead of condensed soup, combine 1/2 cup beef broth, 1/2 cup sour cream, 1 tablespoon flour, and seasonings, then heat until slightly thickened before mixing with the beef.
Slice the potatoes thinly for faster cooking. A mandoline slicer works well for uniform thickness.
You can prepare this make ahead casserole through step 6, cover, and refrigerate for up to 24 hours. Add 10-15 minutes to the initial covered baking time if baking straight from the refrigerator.
