For an extra layer of flavor, try adding a swirl of pesto or a sprinkle of crumbled bacon before baking. Yukon Gold potatoes create a naturally creamy texture, but Russet potatoes can also be used. Make ahead tip: Prepare the casserole up to 24 hours in advance, cover, and refrigerate. Add 10-15 minutes to the baking time if baking from cold.

Follow The Directions
01
StepPreheat oven to 350 degrees F (175 degrees C). Lightly butter a 9x13-inch casserole dish. (5 minutes)
02
StepPlace potatoes in a large pot and cover with cold, salted water. Bring to a boil over high heat. Reduce heat to medium-low and simmer until potatoes are fork-tender, about 15-20 minutes. Drain well, reserving about 1/2 cup of the potato water. (25 minutes)
03
StepReturn the drained potatoes to the pot. Add the sour cream, cream cheese, onion salt, garlic powder, and pepper. Using a potato masher or an electric mixer, beat the mixture until smooth and creamy. Gradually add the reserved potato water, one tablespoon at a time, until you reach your desired consistency. (10 minutes)
04
StepTransfer the mashed potatoes to the prepared casserole dish. Sprinkle evenly with the shredded Cheddar cheese, parsley flakes, and paprika. (5 minutes)
05
StepBake uncovered, in the preheated oven until the cheese is melted, bubbly, and lightly golden brown, about 30-35 minutes. (35 minutes)
06
StepLet stand for 5-10 minutes before serving. (10 minutes)

May 22, 2025I found that the potatoes were a little dry, even after adding the reserved water. Next time, I'll add a bit more sour cream.
