Ingredients
(Tip: You can find the complete list of ingredients and their measurements in the recipe card below.)
Potatoes
Potatoes form the comforting base, offering a creamy texture when baked and absorbing the rich cheese sauce beautifully.
Butter
Butter adds richness, helping create a silky sauce that blends seamlessly with the potatoes.
Sour cream
Sour cream brings tanginess and creaminess, preventing the casserole from feeling overly heavy.
Cream cheese
Cream cheese adds velvety smoothness and helps the casserole hold together without drying out.
Cheddar cheese
Cheddar provides bold, savory sharpness and melts into a beautifully bubbling top layer.
Mozzarella cheese
Mozzarella adds stretch and a mild creamy balance to the stronger cheddar.
Garlic powder
Garlic powder adds depth and warmth, complementing the richness of the cheese.
Onion powder
Onion powder builds savory flavor without adding additional moisture.
Salt and pepper
Essential for seasoning, ensuring every bite is balanced and flavorful.
Green onions
Green onions add a fresh, colorful contrast and brighten the dish after baking.
Optional decorations
Olives, sliced peppers, or edible “monster eyes” can be added on top for a themed Halloween look.
Directions
Preheat your oven and lightly grease a large casserole dish. Begin by boiling the potatoes until just tender; drain and transfer them to a large bowl. Mash lightly, keeping some chunks for texture. In a saucepan, melt butter over low heat and stir in cream cheese until smooth. Add sour cream, garlic powder, onion powder, salt, and pepper, whisking until the mixture becomes cohesive.
Pour the creamy mixture over the warm potatoes and fold gently until well combined. Add half the cheddar and mozzarella, mixing lightly so the cheese is dispersed but not fully melted. Transfer the mixture to the casserole dish and spread evenly. Top with the remaining cheese. Bake until the casserole is bubbling and the top is golden brown. Remove from the oven and allow it to cool for a few minutes before adding optional decorations or sprinkling green onions on top. Serve warm, allowing the cheesy sauce to settle into the mash.
