I'm a firm believer in that mashed potatoes don't require a lot to be delicious. Just some butter, half-and-half, maybe a little cream cheese. But, you know what I'm also a firm believer in? The magical powers of bacon, cheese, crispy fried onions, and potato chips. Yes, potato chips. This mashed potato casserole is ridiculous in the best way possible.
The cooked potatoes are mashed up, then combined with things like creamy onion dip, crispy bacon, cheese, and fried onions. Then everything goes in a casserole dish and is topped with more cheese, more fried onions, and kettle cooked potato chips. Oh my heavens is it wonderful. This dish goes great with Thanksgiving turkey, Christmas ham, or just a good steak dinner!
What kind of potatoes are best for mashed potatoes?
There are a few different types of potatoes you can use for mashed potatoes, but my favorites are russets and Yukon golds. Both are high in starch and mash up nicely. For this recipe, I use russet potatoes because they tend to be a little lighter and fluffier when mashed. Yukon golds would work great too, so use what you like best!
Can you make mashed potato casserole ahead of time?
You sure can! This potato side dish can be made up to two days ahead of time, covered with foil, and refrigerated (unbaked). Wait to mix up the topping and don't add it until just before you pop the casserole in the oven so the onions and chips stay crunchy.

Ingredients
Casserole
- 1/2 cup
(1 stick) salted butter, melted, plus more for the baking dish
- 1
(16-oz.) container sour cream
- 1
(1-oz.) envelope onion soup mix
- 4 lb.
russet potatoes, peeled and cut into large chunks
- 1 cup
heavy cream, warmed
- 1 lb.
bacon, cooked and crumbled
- 8 oz.
monterey jack cheese, shredded (about 2 c.)
- 1/2 cup
lightly crushed crispy fried onions
- 1 1/2 tsp.
kosher salt
Black pepper, to taste
Topping
- 1 cup
lightly crushed crispy fried onions
- 1 cup
lightly crushed kettle cooked potato chips with sea salt
- 1/4 cup
grated parmesan cheese (about 1 oz.)
Chopped chives or green onions, for serving
Directions
- Step 1For the casserole: Preheat the oven to 375°F. Generously butter a 13-by-9-inch baking dish.
- Step 2In a small bowl, stir together the sour cream and onion soup mix. Refrigerate while you prepare the potatoes so the flavors have time to meld.
- Step 3Place the potatoes into a large pot and cover them with cold water by 1 inch. Bring the water to a boil over high heat and cook until the potatoes are fork tender, 20 to 25 minutes.
- Step 4Drain the potatoes well and return them to the same pot. Place the pot back on the same burner (heat turned off) and mash until there are no visible lumps.
- Step 5Add the prepared onion dip, melted butter, heavy cream, bacon, monterey jack cheese, fried onions, and salt, and stir to combine. Season to taste with pepper. Transfer the mashed potatoes to the prepared baking dish, spreading them evenly.
- Step 6For the topping: In a small bowl, stir together the fried onions, potato chips, and parmesan. Sprinkle the mixture evenly over the top of the mashed potatoes. Bake until bubbling and browned on top, 15 to 20 minutes. Sprinkle with chives just before serving.
