Ingredients

  • 6 medium or 4 huge white (red skinned) potatoes
  • 1 tsp salt
  • 1 cup sour cream
  • 8 fresh green onions, chopped with some greens
  • 1 cup (4 oz) shredded sharp Cheddar cheese
  • 1/3 cup butter, melted

Instructions

  1. Peel, quarter, and boil potatoes until barely tender.
  2. Drain, cool, and grate on the large side of a grater or lightly mash.
  3. In a large bowl, gently mix all ingredients except butter.
  4. Place the mixture in a greased, shallow pan.
  5. Top with melted butter.
  6. Bake at 400°F (200°C) for 30 minutes.

Tips & Substitutions

For a creamier texture, you can substitute Greek yogurt for sour cream. If you prefer a little kick, add some diced jalapeños or a sprinkle of cayenne pepper to the mixture. Ensure not to over-boil the potatoes; they should be barely tender for the best consistency. You can use leftover mashed potatoes from another meal if you have them on hand.

Serving Suggestions

This casserole is perfect for potlucks and pairs beautifully with grilled meats or a fresh garden salad. Consider serving it alongside American recipes like BBQ ribs or fried chicken for a hearty meal. For a vegetarian twist, serve with a side of roasted vegetables to complement the richness of the dish.

Storage & Reheating

Store any leftovers in an airtight container in the refrigerator for up to 3 days. To reheat, place in a preheated oven at 350°F (175°C) for about 20 minutes or until heated through. Cover with foil to prevent the top from over-browning while warming.
