Loaded Smashed Potato Casserole is an ultra creamy casserole flavored with 4 types of cheese, bacon, sour cream, and green onion. Goes great with any type of meat and I especially love it as a holiday side.
Boil potatoes in a large pot of salted water just until tender. Drain.
Preheat oven to 350 degrees and grease a 9x13-inch baking dish.
Place potatoes in a large bowl and mash with a potato masher, leaving chunks.
In a medium bowl, mix together cream cheese, sour cream, mayonnaise, salt, pepper, onion powder, and garlic powder until smooth.Add to bowl with potatoes and stir to mix into the potatoes.
Mix in half the green onion, 1 cup of shredded cheddar cheese, all of the mozzarella and Parmesan and half the bacon.
Transfer to prepared baking dish. Sprinkle remaining green onion, cheddar cheese, and bacon on top.Bake for 15 to 20 minutes.
Notes
If red potatoes are large, cut them in half before you boil them.For best flavor, shred your own cheddar cheese and parmesan cheese.Nutritional info is provided as an estimate only and will vary based on brands of products used. It should not be used for specific dietary needs.
