Step-by-Step Cooking Instructions

1. Preheat the Oven
   Set your oven to 375°F so it’s ready by the time your ingredients are prepared.
2. Boil the Potatoes
   Peel and cut the potatoes into chunks. Place them in a large pot of salted water. Bring to a boil and cook until they are fork-tender, about 15 to 20 minutes. Drain thoroughly.
3. Mash the Potatoes
   Return the potatoes to the pot or place them in a large mixing bowl. Add butter, cream cheese, and sour cream while the potatoes are still hot. Use a potato masher or electric mixer to mash until smooth and creamy.To try another comforting dish, see _Tuna Noodle Casserole.
4. Add Seasoning and Milk
   Stir in the milk, garlic powder, salt, and black pepper. Mix well until everything is fully combined and the mixture is smooth.
5. Fold in the Extras
   Add half of the shredded cheese, half the crumbled bacon, and a handful of green onions. Gently fold everything into the mashed potatoes.
6. Transfer to a Baking Dish
   Spoon the mixture into a greased 9×13 inch baking dish. Spread it out evenly with a spatula.
7. Top with More Goodness
   Sprinkle the remaining cheese and bacon over the top. Add a few more chopped green onions for color and flavor.
8. Bake
   Place the dish in the preheated oven and bake for about 25 minutes, or until the cheese is melted and bubbly around the edges.
9. Serve Hot
   Let the casserole rest for about 5 minutes before serving. This helps the flavors settle and makes it easier to scoop.

Tips for Customizing the Recipe

This loaded mashed potato casserole is easy to make your own. Here are some simple ways to change it up without losing the soul of the dish:

• Use Sweet Potatoes
  Swap russet potatoes for sweet potatoes for a slightly sweet and earthy flavor. Great for a fall twist.
• Make It Vegetarian
  Omit the bacon and add sautéed mushrooms or roasted vegetables like broccoli, bell peppers, or spinach.
• Add Protein
  For a main dish version, stir in cooked shredded chicken, ground beef, or chopped ham before baking.
• Make It Spicy
  Mix in diced jalapeños or a dash of hot sauce for a little heat. Smoked paprika also adds a nice depth of flavor.
• Lower the Fat
  Use Greek yogurt instead of sour cream and reduce the butter. Choose low-fat cheese and skip the bacon to lighten it up.
• Go Gluten-Free
  This dish is naturally gluten-free as long as the bacon and cheese are free from additives containing gluten.
