History of Green Bean Casserole

The origins of the green bean casserole can be traced back to 1955, when it was reportedly created by the Campbell Soup Company.

The original recipe was simple and included only four ingredients: canned green beans, cream of mushroom soup, milk, and French fried onions. The recipe became an instant hit and has been a staple of holiday dinners ever since.


For the casserole:

  • Prepare 1 1/2 pounds of fresh green beans by trimming and cutting them in half.
  • 6 slices of bacon, chopped
  • 1/2 cup all-purpose flour
  • 1/2 cup yellow onion, finely chopped
  • 1/2 cup celery, finely chopped
  • 8 ounces mushrooms, finely chopped
  • 2 cloves garlic, minced
  • 1/2 teaspoon dried thyme
  • 1/2 teaspoon kosher salt
  • 1/4 teaspoon freshly ground black pepper
  • 1 1/2 cups chicken broth
  • 1/2 cup heavy cream
  • 1/2 cup Parmesan cheese, grated

For the topping:

  • 1 cup all-purpose flour
  • 1/2 teaspoon garlic powder
  • 1/2 teaspoon smoked paprika
  • 1/2 teaspoon kosher salt
  • 1/4 teaspoon freshly ground black pepper
  • 1 large onion, thinly sliced
  • 1/2 cup buttermilk
  • Vegetable oil, for frying


  1. Preheat the oven to 375 degrees F.
  2. Place a generously salted large pot of water over high heat and bring it to a rolling boil. Add the green beans and cook for 5-6 minutes, until bright green and slightly tender. Drain the green beans and rinse with cold water to stop the cooking process.
  3. In a large skillet, cook the chopped bacon over medium heat until crispy, about 8-10 minutes. Using a slotted spoon, take out the bacon from the skillet and keep it aside.
  4. In the same skillet, add the flour and whisk constantly for 1-2 minutes, until the flour is lightly browned.
  5. Add the chopped onion, celery, mushrooms, garlic, thyme, salt, and pepper to the skillet. Cook for 5-7 minutes, until the vegetables are tender and the mushrooms have released their liquid.
  1. Gradually whisk in the chicken broth and heavy cream until the mixture is smooth. Bring the mixture to a simmer and cook for 5-7 minutes, until it thickens.
  2. Add the grated Parmesan cheese to the skillet and stir until it’s melted and fully incorporated.
  3. Add the blanched green beans and cooked bacon to the skillet and stir to combine.
  4. In a separate bowl, whisk together the flour, garlic powder, smoked paprika, salt, and pepper for the topping.
  5. Dip the sliced onions into the buttermilk, then coat them in the seasoned flour mixture.
  6. Place a Dutch oven or large pot on medium-high heat and add vegetable oil to it, heating it up until it’s hot.
  7. Fry the coated onions in batches until golden brown and crispy, about 2-3 minutes per batch.
  8. Once the green bean mixture is ready, carefully move it to a baking dish that measures 9×13 inches.
  9. Top the casserole with the crispy fried onions.
  10. Bake the casserole for 25-30 minutes, until hot and bubbly.
