Ingredients

Gather your simple ingredients to create this delicious green bean casserole recipe:

  • 1 can (10.5 ounces) Campbell’s® Condensed Cream of Mushroom Soup or Unsalted Cream of Mushroom Soup or Cream of Celery Soup
  • 1/2 cup 2% milk
  • 1 teaspoon soy sauce
  • 4 cups cooked cut green beans
  • 1 1/3 cups French’s® French Fried Onions (amount divided in recipe steps below)
  • Salt and black pepper (to taste)

Notes & Substitutions

You have many options to tailor this casserole to your taste. For the cream of soup, feel free to use cream of celery soup or an unsalted cream of mushroom option. If you prefer, substitute the green beans with fresh blanched beans, thawed frozen beans, or canned cut beans. Any dairy or non-dairy milk works beautifully in place of 2% milk. You can swap soy sauce with Worcestershire sauce or coconut aminos for a similar umami depth. For the topping, consider crushed crackers, panko breadcrumbs, or homemade crispy onions.

Equipment

Preparing this easy casserole requires only a few basic kitchen items. You will need a 1.5-quart casserole dish to bake your delicious creation. A large mixing bowl helps you combine all the ingredients easily. Finally, standard measuring cups and spoons ensure precise ingredient amounts.

Instructions

Creating this comforting green bean casserole recipe is incredibly simple. Follow these steps for a perfect, bubbly dish every time.

Step 1: Prepare the Oven

First, preheat your oven to 350°F (175°C). This ensures your casserole bakes evenly and perfectly.

Step 2: Combine the Base

In a large mixing bowl, fold in the condensed soup, milk, and soy sauce. Next, stir in the cooked green beans until they are well coated. Add 2/3 cup of the French fried onions to the mixture. Season everything with salt and pepper to your taste, ensuring all ingredients are combined.

Step 3: Bake Initial Layer

Pour the entire green bean mixture into your prepared 1 1/2-quart oven-safe casserole dish. Place it in the preheated oven. Bake for 25 minutes, or until the casserole is hot and bubbling around the edges.

Step 4: Add Final Topping

Carefully remove the casserole from the oven. Gently stir the baked mixture to distribute the warmth and flavors. Sprinkle the remaining 2/3 cup of French fried onions evenly over the top of the casserole.

Step 5: Final Bake & Rest

Return the casserole to the oven for an additional 5 minutes. The onions should turn a lovely golden brown and become perfectly crispy. Remove from the oven and let the green bean casserole recipe rest for a few minutes before serving. This resting period allows the flavors to meld beautifully and the casserole to settle, making it easier to serve. Store any leftovers in an oven-safe dish for convenient reheating.

Pro Tips & Troubleshooting

Achieve the perfect green bean casserole recipe with these helpful tips. To prevent soggy onions, ensure you bake the casserole long enough before adding the final topping. For an extra crispy topping, you can extend the final bake time by a minute or two, watching carefully. Always make sure your green beans are drained exceptionally well; excess moisture can thin the sauce. If using unsalted cream of soup, adjust the salt level carefully, tasting as you go. For fresh green beans, blanch them quickly before adding to maintain vibrant color and a tender-crisp texture. Avoid overmixing the casserole base to keep the green beans intact. If you prefer a thinner layer, use a larger casserole dish.
