Mississippi Mud Potatoes are my secret weapon for potlucks and Sunday suppers alike. This Southern casserole brings together creamy potatoes, gooey cheddar, and crisp bacon in one bubbling dish. It is perfect for feeding a crowd or making any meal feel a little more special thanks to its over-the-top, comforting flavors.

The first time I made this, it was for a neighborhood cookout. The empty dish at the end of the night made me realize I had a true crowd-pleaser on my hands. It is now my go-to for both family holidays and weeknight comfort food.

Ingredients

  • Potatoes: choose firm varieties like Yukon Gold or russets for the creamiest texture
  • Cheddar cheese: sharp cheddar brings big flavor use block cheese for best melt
  • Mayonnaise: adds rich creaminess and binds everything together use full fat for the classic result
  • Bacon: smoky and salty crumbled for a crispy topping cook until browned but not burnt
  • Garlic: fresh minced for aromatic depth select firm cloves with tight skins
  • Onion: sweet or yellow onion diced for sweetness and savory flavor look for onions with shiny dry skins

Step-by-Step Instructions

Preheat the Oven:
Set your oven to 325 degrees Fahrenheit making sure the rack is positioned in the center Bakeware should be lightly greased to prevent sticking
Combine Everything:
In your greased baking dish combine diced potatoes shredded cheddar crumbled bacon minced garlic and onion Use your hands or a sturdy spoon to distribute everything evenly every piece should catch some cheese and bacon
Coat with Mayonnaise:
