Ingredients

Fried Onions

  • 1 large yellow onion sliced thin
  • ½ cup buttermilk
  • 1 cup cornstarch
  • 1 teaspoon seasoned salt
  • Oil for frying canola or vegetable

Green Beans

  • 5 tablespoons unsalted butter melted
  • 4 teaspoons kosher salt
  • 2 pounds fresh green beans snapped & string removed

Topping

  • 1/4 cup Panko crumbs
  • 1 tablespoon unsalted butter melted

Green Bean Casserole

  • 4 tablespoons unsalted butter
  • 16 ounces mushrooms stems removed, quartered
  • 1 teaspoon black pepper
  • 2 cloves garlic minced
  • 1/3 cup all purpose flour
  • 3/4 cup chicken broth
  • 1 3/4 cups heavy cream

Instructions

Make the Fried Onions:

  • Preheat oven to 375F. Prepare a 9x11 baking dish with nonstick spray.
  • In a large bowl place the buttermilk.
  • In a separate bowl, combine the cornstarch and season salt.
  • Dip the onion slices in the buttermilk. Shake to remove excess and then toss in the cornstarch mixture to coat.
  • Heat 2-3 inches of oil in a deep pan to 350F. Place a wire rack or tray lined with paper towels close by.
  • In batches, fry the onions in the oil. Stir occasionally with a slotted spoon until golden brown. This will be fast, maybe 2-3 minutes.
  • Using the slotted spoon, remove the fried onions and place on the paper towels. Continue with remaining onions until all are fried. Set aside.

Blanch the Green Beans:

  • Make an ice bath in a large bowl with cold water and ice.
  • In a large pot, bring water to a boil with 3 teaspoons of kosher salt.
  • Add in the green beans and cook for 5 minutes or until crisp tender.
  • Remove with tongs and submerge in the ice bath to stop the cooking and preserve their bright green color.
  • Cool for 2-3 minutes, drain.

Mix the coating:

  • Combine the 1 tablespoon melted butter and the Panko crumbs. Stir to combine.

Make the casserole:

  • In a large skillet over medium high heat, melt 4 tablespoons butter. Cook sliced mushrooms, stirring often, until tender and browned (2-3 minutes).
  • Season with 1 teaspoon salt, pepper. Stir in garlic and mix to combine.
  • Sprinkle the flour over the mushrooms and stir to coat. Slowly pour in the chicken broth, whisking to combine.
  • Bring to a simmer and cook for 1-2 minutes.
  • Turn heat to medium and whisk in the cream. Stir continuously until the sauce thickens. About 4-5 minutes. Remove from the heat and stir in green beans.
  • Spread into the prepared baking dish. Top with Panko mixture. Bake at 375F for 15-20 minutes or until bubbly.
  • Remove from the oven and top with fried onions. Serve warm.

Notes

  • If you prefer thinly sliced green beans, I recommend looking for a fresh french style for this casserole. 
  • When reheating, if your casserole is getting a little dry you can rehydrate it by adding a little cream of mushroom soup while baking.
  • You can also use an air fryer or a slow cooker to reheat this dish if you prefer. 
  • For a gluten-free version of this recipe, you can use gluten-free Panko crumbs and swap out all purpose flour for a gluten-free flour of your choice. 
  • I recommend serving this casserole with some crumbled bacon sprinkled on top because it increases the flavor and adds a nice salty element to the dish. 
  • For my spice lovers, you can top this casserole with a mix of sliced jalapenos and green onion.
  • Try this with Alfredo sauce if you don't want to make the roux.
  • Make it a traditional "friendsgiving casserole" every year!
