Mississippi Mud Potatoes are a rich and creamy baked potato casserole layered with sharp cheddar cheese, crispy turkey bacon, chopped onions, and a smooth, savory blend of mayonnaise and garlic. Baked until golden and bubbling, this classic Southern-inspired comfort dish is perfect for potlucks, weeknight dinners, or holiday tables. The perfect balance of tender potatoes, melted cheese, and smoky crunch makes this recipe an irresistible favorite.
6 cups Russet or Yukon Gold potatoes, peeled and diced
1 cup sharp cheddar cheese, shredded
¾ cup mayonnaise
1 cup turkey bacon, cooked until crispy and crumbled
3 teaspoons garlic, minced
½ cup onion, finely chopped
Salt and black pepper, to taste
Cooking spray or butter for greasing pan
Preheat oven to 325°F (163°C). Lightly grease a 9×13-inch baking dish with cooking spray or butter.
Cook turkey bacon in a skillet until crisp. Drain on paper towels and crumble.
Prepare the potatoes: Peel and dice them into ½-inch cubes. Rinse and drain well to remove excess starch.
In a large mixing bowl, combine diced potatoes, shredded cheddar cheese, crumbled turkey bacon, minced garlic, and chopped onions.
Add mayonnaise to the bowl and gently stir everything together until the potatoes are evenly coated.
Transfer the mixture to the prepared baking dish. Spread it evenly.
Bake uncovered for 1 hour and 30 minutes, or until the potatoes are fork-tender and the top is golden and bubbling.
Optional: Sprinkle extra cheese or chopped green onions on top during the last 10 minutes of baking for added flavor and color.
Let rest for 5–10 minutes before serving to help it firm up.
For a lighter version, substitute half of the mayo with plain Greek yogurt or light sour cream.
If you prefer a crispier texture, broil the dish for the last 2–3 minutes.
Use Yukon Gold for a creamier texture or Russet for a fluffier finish.
Add chopped green onions, bell peppers, or jalapeños for extra flavor.
Can be made vegetarian by omitting turkey bacon or replacing it with a meatless alternative.
