Ingredients
Scale
- 3 lbs Yukon Gold potatoes, peeled and quartered
- 1 cup whole milk, warmed
- 8 tablespoons unsalted butter, softened
- 8 ounces cream cheese, softened
- 1 cup sour cream
- 1 cup shredded sharp cheddar cheese, divided
- 1 cup shredded Monterey Jack cheese
- 1 teaspoon salt
- 1/2 teaspoon black pepper
- 1 cup cooked, crumbled bacon
- 1/2 cup chopped green onions
- 1/2 cup shredded cheddar cheese (for topping)
Instructions
- Preheat your oven to 375 degrees Fahrenheit. Grease a 9×13 inch baking dish.
- Place the peeled potatoes in a large pot and cover with cold, salted water. Bring to a boil and cook until the potatoes are fork-tender, about 15 to 20 minutes.
- Drain the potatoes well and return them to the hot pot to dry out for one minute over low heat, shaking occasionally.
- Remove the pot from the heat. Add the warm milk, softened butter, softened cream cheese, and sour cream. Mash until smooth and creamy.
- Stir in 3/4 cup of the sharp cheddar cheese, the Monterey Jack cheese, salt, and pepper until just combined. Do not overmix.
- Gently fold in the crumbled bacon and most of the green onions, reserving some for garnish.
- Spread the mashed potato mixture evenly into the prepared baking dish.
- Top the casserole evenly with the remaining 1/4 cup sharp cheddar cheese and the final 1/2 cup of shredded cheddar cheese.
- Bake for 25 to 30 minutes, or until the casserole is heated through and the cheese topping is melted and lightly golden brown.
- Let the potato and cheese bake rest for 5 minutes before serving. Garnish with reserved green onions.
Notes
- To make ahead, prepare the casserole through step 6, cover tightly, and refrigerate for up to 2 days. Add 10 to 15 minutes to the baking time if baking directly from the refrigerator.
- For a Bacon Ranch Potato Casserole variation, mix 2 tablespoons of dry ranch seasoning mix into the potato mixture in step 5.
- You can substitute half of the cheddar cheese with Gruyère for a nuttier flavor.
