Crispy prosciutto green bean casserole is a Holiday side dish must make! The recipe gets a few simple upgrades with fresh green beans, crispy prosciutto pieces and creamy gruyere cheese to take this classic to a whole new level! 



2.5 lbs fresh green beans, trimmed

2 – 10.5 oz cans cream of mushroom soup

1 tsp cracked black pepper

1 cup whole milk

1 cup shredded gruyere cheese

2 cups crispy fried onions

3 oz Volpi prosciutto, torn


  1. Preheat oven to 400 F. Line a small baking sheet with parchment paper. Arrange half of the prosciutto pieces on a baking sheet spread apart so they aren’t touching. Bake prosciutto for 5-7 minutes or until crispy. Keep a close eye on it so the prosciutto doesn’t burn. Remove from the oven and let cool. 
  2. Turn oven temperature down to 350 F. Bring a large stock pot of water to a rolling boil. Cook green beans for 3-4 minutes and transfer into a large bowl filled with ice water. This will stop the cooking process of the beans. Once cooled, drain and transfer beans to a separate large bowl. 
  3. In a large bowl, stir together the soup, milk, black pepper, cheese, 1 cup of crispy fried onions, green beans and crumble half of the crispy prosciutto pieces. Transfer mixture to a large casserole dish. 
  4. Cover the foil and bake for 20 minutes. Remove foil, top with remaining onions and other half of the prosciutto over the beans. Bake for an additional 5-10 minutes or until bubbly and golden brown.
