6 cups prepared mashed potatoes OR 6 large russet potatoes, peeled and chopped
8 ounces cream cheese, softened reduced fat is okay
1 1/2 cup shredded cheddar or monterey jack cheese divided
1/2 cup sour cream reduced fat is okay
1 teaspoon onion powder
1 teaspoon garlic powder (omit if using prepared garlic mashed potatoes)
2 teaspoons salt
1/2 teaspoon black pepper
Preheat oven to 350 degrees and grease a 2-quart baking dish.
If using prepared mashed potatoes, move ahead to step 3. If using russet potatoes, place potatoes in a large pot, cover with water, cover the pot and bring to a boil. Cook for 20-25 minutes until potatoes are very tender, drain the pot. Transfer potatoes to a large bowl and mash until smooth.
Combine potatoes with cream cheese, sour cream, half cup shredded cheese, onion powder, garlic powder (if using), salt, and pepper and mash/mix everything til combined and smooth.
Spoon potatoes into prepared baking dish. Top with remaining cheese.
Cover the baking dish and cook for 35-40 minutes. Switch to BROIL for 3-5 minutes longer (watch closely so the cheese doesn’t burn). Allow to cool slightly before serving.
