3 lbs. potatoes, peeled and cut into 1/4-in. slices
1 lb. bulk pork sausage (I prefer Jimmy Dean’s)
1 medium onion, chopped
1/4 cup butter, melted
2 cups shredded cheddar cheese
Place potatoes in a large saucepan and cover with water. Bring to a boil. Reduce the heat; simmer, uncovered, until potatoes are tender, 8-10 minutes. Meanwhile, crumble sausage into a large skillet; add onion. Cook over medium heat until meat is no longer pink; drain if necessary.
Drain the potatoes; arrange them in an ungreased 13×9-in. baking dish. Drizzle with butter. Add sausage mixture and stir gently. Sprinkle with cheese.
Bake, uncovered, at 350° until cheese is melted, 5-7 minutes
