About seven cups of peeled, diced potatoes are placed in a casserole dish with shredded cheddar cheese, bacon, green onion, and garlic salt. All of this is combined with mayo, which ties everything together and adds plenty of richness…

Then it bakes slowly and slowly. They start at 325°F, which isn’t too low, but it’s low enough that the potatoes can hang around for a long time till they’re irresistibly delicate while still having a wonderful browned coating.

INGREDIENTS
6-7 cups peeled and sliced potatoes
2 cups grated cheddar cheese
1 (1 pound) package cooked and crumbled bacon
1 tsp. garlic salt
1 quart mayonnaise
1/2 cup finely sliced green onions
