Preparation:

Preheat your oven to 325°F (163°C). Prepare a 9×13 baking pan by greasing it lightly.
Combine Ingredients:
In the prepared baking pan, mix together the diced potatoes, shredded cheddar cheese, cooked and crumbled bacon, minced garlic, and chopped onion.
Add Mayonnaise:
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.

 enjoy!
