Green Bean Casserole is a quintessential part of the American Thanksgiving celebration menu of foods. The traditional version of this dish includes canned green beans, cream of mushroom soup, and French fried onions. This dish was created at the Campbell Soup Company by Dorcas Reilly in 1955 and has since become a family favorite during Thanksgiving. Our version is similar to the original but offers fresh green beans, a mushroom substitute for those not so fond of fungi, and we will show you how to make those French fried onions from scratch. To make this dish even more decadent, we will use Worcestershire Sauce and add a little Gruyère cheese for that creamy, nutty, salty flavor familiar to French Onion Soup. We hope you enjoy our version of this American classic and share it with your friends and family at your next Thanksgiving celebration.

Ingredients

French Fried Onions
  • 500 ml Buttermilk

  • 4 Medium Onions thinly sliced

  • 1 cup All purpose flour

  • 1/2 teaspoon Salt

  • ½ teaspoon Black Pepper

  • Oil For Frying

Casserole
  • 600 grams Green Beans fresh

  • 1 can of 10.5 ounce Cream of Celery soup

  • 100 ml Whole Milk

  • 1 teaspoon Worcestershire Sauce

  • 1 teaspoon Garlic Powder

  • 1/2 cup Gruyère Cheese shredded

Instructions

French Fried Onions

Break apart the onion slices, place them into a bowl of buttermilk and let marinate for 10-15 minutes if you don’t have buttermilk add two tablespoons of vinegar to 500 ml of whole milk and mix.

In a large bowl mix the salt, black pepper and flour together.

Prepare a stock pot, heavy bottom pot or deep fryer with oil and bring to 350 F/ 177 C

Prepare a drying station with a plate with paper towels for resting the French fried onions when they are finished cooking.

Once the onions have marinated, remove them from the milk bath and toss them in the bowl of the flour mixture, making sure to coat them well.

When the oil is ready at 350 F, place one portion of onions into the oil and fry until golden brown, then remove from the oil and place on the drying station.

Repeat step 6 until all the onions are fried, then set aside to use in the casserole.

Blanching the Green Beans

Wash, rinse, and trim the ends of the green beans and set them aside.

Prepare a bowl of ice water for the green beans to be placed into after blanching.

Using a large 4 quart stock pot fill ⅔ the way with water and add 1 teaspoon of salt and bring to a boil.

Once the water is boiling, add the green beans and cook for 5 minutes.

After 5 minutes of cooking, remove from the heat, strain the green beans and place them into the bowl of ice water immediately.

Rinse the green beans in the ice water for 3 minutes, then remove, strain, and toss them to remove all excess water.

Casserole

Grease a 2-quart casserole dish and set aside.

Preheat oven to 350 F/ 177 C and place a rack on the middle shelf.

Into a bowl, mix the cooked green beans, milk, soy sauce, garlic powder, and half the portion of the French Fried Onions you fried earlier.

Pour this mixture into the casserole dish and bake for 20 minutes.

After 20 minutes, remove the dish from the oven and give a quick stir, then sprinkle the cheese over the top followed by the other half portion of French Fried Onions and return to the oven to bake for another 5 minutes or until the top is golden brown.

Remove from the oven and allow cooling for 5 -10 minutes before serving.

Serve warm as a vegetable side dish with your meal, such as Fall Apart Slow Cooker Pork Chops.
