Instructions

Preheat the oven to 350°F (175°C).
Boil the cubed potatoes in salted water for 15–20 minutes, or until fork-tender. Drain well and mash until smooth.
Stir in sour cream, melted butter, milk, garlic powder, paprika, salt, and black pepper until creamy and fully combined.
Fold in 1 1/2 cups of shredded cheddar cheese and half of the chopped green onions.
Transfer the mixture to a greased 9×13-inch baking dish and spread evenly.
Sprinkle the remaining cheddar cheese on top, followed by mozzarella if using, and finish with the remaining green onions.
Bake uncovered for 20–25 minutes, until the cheese is melted, bubbly, and lightly golden.
Garnish with additional green onions or chives if desired and serve warm.

Notes

For a crispy topping, mix breadcrumbs with melted butter and sprinkle over the casserole before baking.

Add sautéed mushrooms, steamed broccoli, or roasted red peppers for extra flavor and texture.

For added heat, top with sliced jalapeños or drizzle with hot sauce.

Store leftovers in an airtight container in the refrigerator for up to 4 days.

Freeze for up to 2 months; thaw overnight in the refrigerator before reheating.
