1 (10.75 ounce) can condensed cream of chicken soup
•
0.25 cup sour cream
•
0.75 cup shredded Cheddar cheese

salt to taste
Instructions
Place potatoes into a large pot and cover with salted water; bring to a boil. Reduce the heat to medium-low and simmer until tender, about 10 minutes. Drain.
While potatoes are cooking, melt butter in a small skillet over medium heat. Add onion and sauté until golden brown. Set aside.
Preheat the oven to 350 degrees F (175 degrees C).
Mash potatoes with condensed soup and sour cream until smooth and creamy. Mix in onions, 3/4 cup Cheddar cheese, salt, and pepper. Spoon into a 2-quart casserole dish.
Bake in the preheated oven for 30 minutes. Sprinkle remaining 1/4 cup Cheddar over top and bake for 10 more minutes. Serve hot.
