Add the mayonnaise to the potato mixture and stir until everything is evenly coated.
Bake:
Place the pan in your preheated oven and bake for about 1 1/2 hours, or until the potatoes are tender and the top is golden brown.
Serve:
Serve hot straight from the oven. Enjoy the creamy, cheesy, bacon-filled delight that is Mississippi Mud Potatoes!
Notes
For a lighter version, substitute sour cream with Greek yogurt and use low-fat cheese.
Add jalapeños or chili flakes to introduce a spicy kick to the dish.
