Peel and slice the potatoes thinly (about 1/8-inch thick slices). You can use a mandolin or knife for uniform slices.
Mix the Sauces:
In a medium bowl, combine the cream of mushroom soup, cream of cheddar soup, and milk. Stir until smooth.
Assemble the Casserole:
In the greased casserole dish, arrange a layer of sliced potatoes.
Spread a portion of the cooked ground beef mixture on top.
Pour some of the soup mixture over the beef.
Sprinkle about 1/3 of the shredded cheddar cheese over the top.
Repeat the layers until all ingredients are used, finishing with a final layer of shredded cheddar cheese.
Bake:
Cover the casserole with aluminum foil and bake for 60-70 minutes until the potatoes are tender. You can test by inserting a fork.
Remove the foil and bake for an additional 10-15 minutes to brown the cheese on top.
Garnish and Serve:
Let the casserole cool slightly, and garnish with fresh parsley or chopped green onions if desired.
Serve warm and enjoy!
Tips:
You can add extra vegetables like peas, carrots, or corn for more texture.
If you prefer, swap the ground beef with ground turkey or chicken.
