Grandma’s Potatoes Recipe
Creamy, cheesy, buttery, and irresistibly crispy on top—Grandma’s Potatoes are the ultimate comfort food casserole, perfect as a main dish or a hearty side.
- 4 –5 large potatoes peeled and sliced thinly
- 1 medium onion finely chopped
- 2 cups shredded cheddar cheese or a cheddar-mozzarella blend
- 1 cup sour cream
- 1 can cream of chicken soup or cream of mushroom for vegetarian
- ½ cup milk
- ¼ cup melted butter
- Salt and pepper to taste
- ½ cup grated Parmesan cheese optional
- 1 cup cornflakes or crushed Ritz crackers for topping
- 1 –2 tablespoons melted butter for topping
Set your oven to 350°F (175°C) and grease a 9x13-inch baking dish with butter or cooking spray.
Peel and slice the potatoes thinly (about ⅛ inch). Use a mandolin for speed and even slices.
In a large bowl, combine sour cream, cream of chicken soup, milk, ¼ cup melted butter, salt, pepper, and half the cheese. Stir until smooth.
Layer potatoes in the dish, followed by some creamy mixture and chopped onions. Repeat until everything is used, ending with the sauce on top.
Top with remaining cheese. Mix crushed cornflakes or Ritz with 1–2 tbsp melted butter and sprinkle over the top. Add Parmesan if using.
Cover with foil and bake for 45–55 minutes. Uncover and bake 15 more minutes until golden and bubbling.
Let rest 5–10 minutes before serving. Serve warm.
