Kitchen Equipment Needed

• Large pot
• Potato masher or electric mixer
• Mixing bowls
• 9×13-inch casserole dish
• Spatula

Ingredients Overview

• Potatoes: Russet potatoes work best for their fluffy texture.
• Cheese: A mix of sharp cheddar and mozzarella adds gooey richness.
• Sour Cream: Creates a creamy consistency and tangy flavor.
• Green Onions: Add a pop of freshness and mild onion flavor.

Ingredients

• 6 large russet potatoes, peeled and cubed
• 1/2 cup butter, softened
• 1 cup sour cream
• 1/2 cup milk (or as needed)
• 2 cups shredded cheddar cheese, divided
• 1 cup shredded mozzarella cheese
• 3 green onions, sliced (reserve some for garnish)
• Salt and pepper to taste

Instructions

1. Cook the Potatoes:
   • Place the cubed potatoes in a large pot and cover with cold water. Add a pinch of salt and bring to a boil. Cook until potatoes are fork-tender, about 15–20 minutes. Drain well.
2. Mash the Potatoes:
   • Return the potatoes to the pot and mash them with butter, sour cream, and milk until creamy. Adjust the milk quantity for your preferred consistency. Season with salt and pepper.
3. Mix In Cheese and Onions:
   • Stir in 1 1/2 cups of cheddar cheese, all the mozzarella cheese, and most of the green onions. Mix until evenly combined.
4. Assemble the Casserole:
   • Transfer the potato mixture to a greased 9×13-inch casserole dish. Spread evenly with a spatula.
5. Top with Cheese:
   • Sprinkle the remaining 1/2 cup of cheddar cheese over the top of the casserole.
6. Bake:
   • Preheat your oven to 375°F (190°C). Bake the casserole for 20–25 minutes, or until the cheese is melted and golden.
7. Garnish and Serve:
   • Sprinkle with reserved green onions before serving. Serve warm and enjoy!

Recipe Tips

• Make Ahead: Prepare the casserole up to the baking step, cover, and refrigerate. Bake just before serving.
• Optional Add-ins: For extra flavor, mix in roasted garlic or a pinch of smoked paprika.
• Cheese Variations: Experiment with Monterey Jack, Gruyere, or Parmesan for different flavor profiles.
