Ingredients
(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)
4 pounds russet potatoes, peeled and cubed
4 cloves garlic, mashed
5 tablespoons butter
1 cup sour cream
1/2 cup milk
2 cups shredded cheddar cheese
1/2 cup shredded mozzarella cheese
1/4 cup chopped green onions
1 teaspoon salt
1/2 teaspoon black pepper
Directions
Start by bringing a large pot of salted water to a boil. Add the cubed potatoes and cook until fork-tender, about 15 to 20 minutes. Drain the potatoes thoroughly and return them to the pot.
Add the mashed garlic and butter to the hot potatoes. Mash everything together until smooth and creamy. For best results, use a potato masher or hand mixer to eliminate lumps.
Stir in the sour cream and milk, mixing until the texture becomes light and fluffy. Add salt and black pepper, adjusting to taste. Fold in one and a half cups of cheddar cheese and half of the mozzarella cheese, reserving the rest for topping.
Preheat your oven to 180°C (350°F). Transfer the potato mixture into a greased baking dish, spreading it evenly. Sprinkle the remaining cheddar and mozzarella cheese over the top.
Bake for 25 to 30 minutes, or until the cheese is melted and bubbly with a light golden color. Remove from the oven and let it cool slightly before serving. Garnish with chopped green onions for a fresh finish.

Variations
You can customize this casserole in many ways. Add cooked shredded chicken for extra protein, or mix in sautéed mushrooms for a deeper flavor. For a slightly lighter version, replace sour cream with plain yogurt. You can also experiment with different cheeses like gouda or parmesan to change the flavor profile. Adding a pinch of paprika or dried herbs can enhance the aroma and taste.
Storage/Reheating
Store any leftovers in an airtight container in the refrigerator for up to 3 days. To reheat, place the casserole in an oven-safe dish and warm at 180°C until heated through. You can also reheat individual portions in the microwave, though the oven method keeps the texture better. If the casserole seems dry, add a splash of milk before reheating to restore creaminess.
