Ingredients Method Notes

Ingredients
  

  • 3 tablespoons butter
  • 12 oz sour cream
  • 1/2 teaspoon black pepper
  • 1/2 cup sliced green onions
  • 2 cups diced ham steak
  • 8 oz shredded sharp cheddar cheese
  • 30 oz frozen shredded hash browns (thawed)
  • 1 tablespoon extra virgin olive oil
  • 4 oz mushrooms (chopped)

Method
 

  1. Heat olive oil in a saucepan over medium-high heat, then add chopped mushrooms and sauté for 5-7 minutes until golden brown.
  2. Add butter to a 9x13” baking dish and melt it in the oven while preheating to 350 degrees.
  3. In a large mixing bowl, combine sour cream, pepper, green onions, diced ham, and shredded cheese.
  4. Fold in the thawed hash browns until thoroughly combined.
  5. Scoop the hash brown mixture into the casserole dish and spread into an even layer.
  6. Bake uncovered for 60-70 minutes, rotating halfway through, until golden and bubbly.
  7. Let the casserole cool for 20-30 minutes before serving.

Notes

- For a truly golden top, you can finish the casserole under the broiler for 2-3 minutes, but watch it carefully to prevent burning.
- If preparing ahead, fully assemble the casserole, cover tightly with foil, and refrigerate for up to 24 hours. Add an extra 10-15 minutes to the baking time if baking from cold.
- I found that making sure the hash browns are completely thawed and patted dry is crucial for avoiding a watery casserole; excess moisture can make the final dish less firm and bubbly.
