The day I first made this, we'd invited a neighbor—a bachelor farmer—over, and I wanted to fix something hearty. It was a hit instantly. These days, our three sons enjoy it as a change from regular mashed potatoes. We've found that it's best served with beef...either with or without gravy. —Kathy Smith, Granger, Indiana

Ingredients

2-1/2 to 3 pounds white potatoes, peeled and cubed
1 teaspoon salt, divided
1 medium onion, finely chopped
1/2 pound fresh mushrooms, chopped
3 tablespoons butter, divided
1/2 cup sour cream
1/4 teaspoon pepper
1/4 cup grated Parmesan cheese

Directions

Preheat oven to 400°. Place potatoes in a large saucepan and cover with water. Add 1/2 teaspoon salt. Bring to a boil. Reduce heat; cover and cook until tender,10-15 minutes. Drain and mash (do not add butter or milk).
In a large skillet, saute onion and mushrooms in 2 tablespoons butter just tender, 3-4 minutes. Stir into potatoes along with sour cream, pepper and remaining salt. Spoon into a greased 2-qt. baking dish. Sprinkle with cheese; dot with remaining butter.
Bake, uncovered, until heated through and golden brown, 20-25 minutes.
