Step-by-step process (detailed)
1. Cook the potatoes
Peel potatoes and cut into large chunks. Place in a large pot and cover with cold, salted water. Bring to a boil, then simmer 15–20 minutes until fork-tender. Drain well.
2. Mash the potatoes
Return hot potatoes to the pot. Add butter and mash until mostly smooth. Warm potatoes absorb butter better, creating a creamier base.
3. Add creamy ingredients
Stir in sour cream, milk, garlic powder, salt, and black pepper. Mash or mix until smooth and fluffy. Taste and adjust seasoning.
4. Fold in the mix-ins
Stir in 1½ cups shredded cheese and most of the bacon, reserving some for topping.
5. Assemble the casserole
Transfer potato mixture to a greased 9×13-inch baking dish. Spread evenly and smooth the top.
6. Add toppings
Sprinkle the remaining cheese and the reserved bacon evenly over the casserole.
7. Bake
Bake uncovered at 375°F (190°C) for 25–30 minutes, until hot throughout and bubbly around the edges.
8. Finish and garnish
Remove from oven and sprinkle with green onions. Let rest 5–10 minutes before serving.
Mistakes to avoid
