Ingredients

Potatoes and Dairy

  • 3 pounds russet potatoes, peeled and cubed
  • 1/2 cup unsalted butter
  • 1 cup sour cream
  • 1 cup heavy cream

Cheeses

  • 2 cups shredded sharp cheddar cheese (or more, to taste)
  • 1 cup shredded mozzarella cheese

Seasonings and Add-ins

  • 1/4 cup chopped green onions
  • 2 teaspoons garlic powder
  • 1 teaspoon onion powder
  • 1 teaspoon paprika
  • 1/2 teaspoon ground black pepper
  • Salt, to taste
  • 1/2 cup crispy fried onions (optional, for topping)
  • 1 tablespoon olive oil or butter (for greasing the baking dish)

Instructions

  1. Prepare the Potatoes: Peel and cube 3 pounds of russet potatoes into evenly sized pieces to ensure they cook uniformly. Place them in a large pot and cover with cold water. Add a pinch of salt to the water.
  2. Boil the Potatoes: Bring the pot to a boil over medium-high heat and cook the potatoes until they are tender when pierced with a fork, approximately 15-20 minutes. Drain thoroughly once cooked.
  3. Mash the Potatoes: Return the drained potatoes to the pot or a large mixing bowl. Add 1/2 cup unsalted butter, 1 cup sour cream, and 1 cup heavy cream. Mash everything together until smooth and creamy.
  4. Add Seasonings and Cheeses: Stir in 2 teaspoons garlic powder, 1 teaspoon onion powder, 1 teaspoon paprika, 1/2 teaspoon ground black pepper, and salt to taste. Then, fold in 2 cups shredded sharp cheddar cheese, 1 cup shredded mozzarella cheese, and 1/4 cup chopped green onions, mixing until evenly combined.
  5. Prepare the Baking Dish: Preheat your oven to 350°F (175°C). Grease a baking dish with 1 tablespoon olive oil or butter to prevent sticking.
  6. Assemble and Bake: Transfer the cheesy mashed potato mixture into the greased baking dish, spreading it out evenly. Optionally, sprinkle 1/2 cup crispy fried onions over the top for added texture. Bake uncovered for 25-30 minutes, or until the cheese is bubbly and the top is golden brown.
  7. Serve: Remove the dish from the oven and let it cool slightly before serving. Garnish with additional green onions if desired. Enjoy as a hearty and delicious side dish!

Notes

  • Russet potatoes are ideal due to their high starch content, creating fluffy mashed potatoes.
  • Adjust the amount and type of cheese according to taste preferences; other melting cheeses can be used.
  • If you prefer a lighter version, substitute heavy cream with milk and reduce the butter slightly.
  • The crispy fried onions on top are optional but add a delightful crunch.
  • Ensure you don’t over-mash the potatoes to keep some texture.
  • This dish can be prepared a day ahead and reheated in the oven for convenience.
