A big thank you to Volpi Foods for sponsoring this post!

This crispy prosciutto green bean casserole has all of the classic ingredients: cream of mushroom soup, crispy fried onions, fresh green beans and some simple new ingredients that make this casserole a flavor power house!

Green bean casserole is SUCH a classic at our house and every year my Dad always wonders how I’m going to top last year’s batch. In the past I’ve done fresh mushrooms, a homemade sauce and tons of other swaps, but after this years prosciutto addition I am officially converted…

I’m adding in creamy gruyere cheese and crispy pieces of Volpi prosciutto to deepen the umami flavor and add in extra rich and creaminess to every bite.

Ingredients:

fresh green beans – fresh is the way to go, I’ll never touch a frozen bag or can of beans.
can of cream of mushroom soup – a non negotiable. It’s a classic for a reason and canned cream of mushroom soup lives up to the timeless quality of this recipe.
whole milk – whole milk makes the sauce rich and creamy
gruyere cheese – deepens the rich flavor, adds extra creaminess to the sauce and gives the whole recipe a subtle nuttiness.
crispy fried onions – crunchy, salty and umami rich crispy onions give a real boost in texture and flavor
Volpi Foods prosciutto – truly the star of the show on or off a charcuterie board. Celebrate flavors that bring you joy and make everyone gather around the table with @VolpiFoods Heritage Prosciutto. I love sprinkling some crisped prosciutto into my favorite holiday dishes to elevate the flavor.

How to make Crispy Prosciutto Green Bean Casserole

Crisp the prosciutto: 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.
Prepare the fresh beans: 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.
Prep the casserole: 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.
Bake the casserole: 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.

Cooking tips:

This casserole can be prepped ahead of time! You can prep most of this casserole 1-2 days in advance. I prep up until step 3 (once the dish is made up in the casserole!) and tightly wrap with plastic wrap and refrigerate. Continue with the remaining steps and baking time.

Use fresh green beans! I can’t tell you enough how much of a difference fresh beans makes. I find that using frozen and canned beans makes your casserole very mush and lack flavor. Be sure to trim and blanch your beans before making the casserole.
