Mississippi Mud Potatoes are a comforting, creamy, and cheesy potato bake that I love making when I want something rich and satisfying. With tender diced potatoes, sharp cheddar cheese, green onions, and a smooth mayonnaise base, this casserole delivers indulgent flavor with every bite. It’s the kind of dish that’s easy to prepare and perfect for serving at family dinners or gatherings.

Why I Love This Recipe

I love this recipe because it transforms simple ingredients into something truly delicious. The potatoes bake up soft and tender, soaking in the flavors of the cheese and seasonings. The creamy texture combined with the golden, crispy top is irresistible. Plus, it’s a straightforward dish that comes together with little fuss but always makes a big impression.

Ingredients

(Here's a tip: Check out the full list of ingredients and measurements in the recipe card below.)

6–7 cups potatoes, peeled and diced
2 cups cheddar cheese, grated
1 teaspoon garlic salt
1 cup mayonnaise
½ cup green onions, thinly sliced

Directions

Preheat the oven to 325°F (163°C).
In a 9x13-inch baking dish, I mix the diced potatoes, cheddar cheese, garlic salt, and green onions together.
I stir in the mayonnaise until everything is well coated.
I bake the mixture for about 1 hour and 30 minutes, until the potatoes are soft and the top is golden and bubbling.
Once done, I let it sit for a few minutes before serving to help everything set.

Servings and Timing

This recipe makes enough to serve 6 to 8 people. It takes about 15 minutes to prepare and 1 hour and 30 minutes to bake, so the total time is roughly 1 hour and 45 minutes.

Variations

Cheese Swap: I sometimes use a blend of cheeses like Monterey Jack or mozzarella for a milder taste.
Extra Veggies: I like to mix in diced bell peppers, mushrooms, or even peas to add some color and nutrition.
Spicy Version: I add chopped jalapeños or a dash of hot sauce for a little heat.
Herbed Twist: Fresh herbs like parsley or thyme give it an earthy freshness.
Creamy Boost: I occasionally add a dollop of sour cream or a bit of cream cheese to make it even richer.

Storage/Reheating

I let the leftovers cool and then store them in an airtight container in the fridge for up to 4 days. When reheating, I cover the dish with foil and place it in a 350°F oven until warmed through—usually about 20 minutes. For a quick option, I microwave individual portions for 2–3 minutes, stirring halfway through. I don’t recommend freezing, as the potatoes can become grainy.

FAQs

What kind of potatoes should I use?

I prefer Russet or Yukon Gold potatoes. They hold their shape nicely and bake up tender without turning mushy.

Can I make this dish ahead of time?

Yes, I often assemble it a day in advance and keep it covered in the fridge. When I’m ready to bake, I just add a few extra minutes to the cooking time.

Is there a mayonnaise alternative?

When I want a different flavor, I swap the mayonnaise for sour cream or Greek yogurt. It gives the dish a tangy twist and keeps the creamy texture.

How can I make it more filling?

I sometimes add cooked veggies or even a layer of beans to make the casserole more hearty without changing its comforting nature.

Can I cook it in a slow cooker?

Yes, I mix everything and cook it on low for about 6 hours. While it won’t have a crispy top, it still comes out creamy and flavorful.

Conclusion

Mississippi Mud Potatoes are one of my favorite comfort foods. They’re creamy, cheesy, and incredibly easy to prepare, making them a staple in my recipe rotation. Whether I’m making them for a family dinner or taking them to a potluck, they always disappear fast. I love how flexible the recipe is, allowing me to tweak it based on what I have on hand or who I’m serving.
