Three Cheese Mashed Potato Casserole: A Comfort Food Classic

There’s something deeply nostalgic about mashed potatoes.

Her mashed potatoes were legendary, but this Three Cheese Mashed Potato Casserole takes that comforting classic to a whole new level of cheesy, delicious indulgence. It’s a dish that warms the soul and brings everyone to the table with smiles.

Recipe Overview

Prep Time: 15 minutes
Cook Time: 15-20 minutes
Total Time: 30-35 minutes
Servings: 4
Dietary Type: Not Gluten-Free

Ingredients

4 large potatoes, peeled and cubed
1 cup sour cream
1 (3 ounce) package cream cheese, softened
1/4 cup butter, softened
2/3 cup milk
1/2 cup shredded cheddar cheese
1/2 cup shredded muenster cheese
1 1/2 teaspoons salt
1/2 teaspoon pepper

Equipment Needed

Large pot
Mixer (hand or stand)
2-quart casserole dish
Measuring cups and spoons

Instructions

Preheat your oven to 400°F (200°C). Lightly grease a 2-quart casserole dish.
Place the peeled and cubed potatoes in a large pot. Cover with water and bring to a boil over high heat. Cook for about 15 minutes, or until the potatoes are tender enough to be easily pierced with a fork.
Once the potatoes are tender, drain them thoroughly. Return the drained potatoes to the pot.
Add the sour cream, softened cream cheese, and softened butter to the pot with the potatoes.
Using a mixer (either hand mixer or stand mixer), beat the potatoes and the added ingredients until smooth and creamy. Be careful not to overmix, as this can make the potatoes gummy.
Stir in the milk, shredded cheddar cheese, shredded muenster cheese, salt, and pepper until well combined.
Spoon the mashed potato mixture into the prepared 2-quart casserole dish, spreading it evenly.
Bake uncovered at 400°F (200°C) for 15 to 20 minutes, or until the casserole is thoroughly heated and the cheese is melted and bubbly.

Expert Tips & Tricks

For extra creamy mashed potatoes, use Yukon Gold potatoes. They have a naturally buttery flavor and texture.
Don’t have muenster cheese on hand? Monterey Jack or Havarti cheese make excellent substitutes, offering a similar mild and creamy flavor.
To prevent gummy potatoes, avoid overmixing. Mix just until the ingredients are combined.
If you prefer a smoother texture, you can use a potato ricer instead of a mixer.
For a richer flavor, brown the butter before adding it to the potatoes. Be careful not to burn it.
This casserole can be assembled ahead of time and stored in the refrigerator for up to 24 hours before baking. Add a few minutes to the baking time if baking from cold.
For a golden-brown top, broil the casserole for the last minute or two of baking, keeping a close eye on it to prevent burning.
Add roasted garlic to enhance the flavor.

Serving & Storage Suggestions

This Three Cheese Mashed Potato Casserole is a delightful side dish that complements a variety of main courses. Serve it alongside roasted chicken, grilled steak, or baked ham for a satisfying and comforting meal. Garnish with a sprinkle of fresh parsley or chives for a pop of color.

Leftovers can be stored in an airtight container in the refrigerator for up to 3-4 days. To reheat, microwave individual portions or bake the entire casserole in a preheated oven at 350°F (175°C) until heated through. You may need to add a splash of milk to rehydrate the potatoes if they have dried out during storage.

While not recommended for long-term storage, this casserole can be frozen. Allow it to cool completely before wrapping it tightly in plastic wrap and then aluminum foil. Freeze for up to 2 months. Thaw overnight in the refrigerator before reheating. The texture may be slightly different after freezing and thawing.
