Rocky Top Casserole
This is a real crowd pleasing meat and potatoes meal! This dish, inspired by the rolling hills and southern charm of the Appalachian region, combines ground beef, potatoes, tomatoes, corn, and cheese for a hearty supper that you’ll love.
Ingredients/Substitution Ideas

Pour in the water and scrape bottom of pot so that nothing is sticking. Turn off Instant Pot.
Lay the potatoes on top of the beef. Spread the potatoes out so they aren’t stacked on top of each other.

Any substitute for onion soup mix? I have onion powder?
I haven’t made this yet but it looks delicious!! Was wondering if I could use noodles instead of potatoes?
yes you can. I would use 2 cups of water for every 8 ounces of pasta you add in.
This was really easy and tasty. Both my husband and I enjoyed it and looked forward to eating the leftovers. I used red potatoes (a bit more than 1.5lbs) because it’s what I had and wanted to use up and a 10oz bag of frozen corn instead of canned. The leftovers reheated well. I would definitely make it again.
