Step-by-Step Instructions for Nani’s Mashed Potato Casserole Recipe

Here’s how to make this rich and satisfying potato casserole step by step:

1. Prepare the Mashed Potatoes: Peel and cube 4 pounds of potatoes. Boil in salted water until tender, about 15-20 minutes. Drain and return to the pot.
   • Tip: Use starchy potatoes like Russets or Yukon Gold for the creamiest texture.
2. Mash the Potatoes: Add 1/2 cup of milk, 1/2 cup of sour cream, and 4 ounces of cream cheese to the potatoes. Mash until smooth and creamy. Season with salt and pepper to taste.
   • Variation: For extra flavor, add garlic powder or fresh chives.
3. Add Cheese: Stir in 1 cup of shredded cheddar cheese until evenly distributed.
   • Optional: Try a mix of cheddar and mozzarella for a gooier texture.
4. Transfer to Baking Dish: Spread the mashed potatoes into a greased 9×13-inch baking dish, smoothing the top.
   • Pro Tip: Make the potatoes ahead and refrigerate for up to 2 days, then bake before serving.
5. Prepare the Topping: In a small bowl, melt 2 tablespoons of butter and combine with 1/2 cup panko bread crumbs. Sprinkle this mixture evenly over the mashed potatoes.
   • Serving Idea: Add grated Parmesan to the topping for an extra savory flavor.
6. Bake the Casserole: Preheat the oven to 350°F (175°C). Bake for 30 minutes, or until the top is golden brown and the cheese is melted and bubbly.
   • Optional: Broil for the last 2 minutes for an even crispier topping.
7. Serve and Enjoy: Let the casserole cool slightly before serving. Garnish with chopped green onions or parsley if desired.
   • Optional Topping: Add crumbled bacon or extra cheese on top for a richer dish.
