1 cup shredded mozzarella cheese

½ cup shredded Cheddar cheese

½ cup sour cream

½ cup mayonnaise

4 tbsp of salted butter, cut into small pieces


Preheat oven 350 degrees F (175 degrees C). Then grease a deep 9×13-inch baking dish with cooking spray.

Add and place yellow and red potatoes into a large pot and cover with salted water; let it boil. Cook until soft, about 10 minutes. Drain.

Add and combine mozzarella cheese, Cheddar cheese, sour cream, and mayonnaise in a large bowl, mix well. Add potatoes and toss slowly, use a wooden spoon or flat spatula to avoid mashing the potatoes.

Put potatoes into the prepared pan. Then dot butter over the top and cover with foil.

Bake for 25 to 30 minutes in the preheated oven. Remove from oven and uncover. Then preheat the oven’s broiler, return to the oven and broil until the top turns brown for about 5 minutes.


If required, you can also line the baking pan up with parchment paper. If desired, use a deep or large pan.
