FAQs

1. Who invented green bean casserole?

The recipe was created in 1955 by Campbell’s employee Dorcas Reilly at their headquarters in Camden, New Jersey.

2. What are the 6 original ingredients?

The classic Campbell’s recipe includes:

Canned or fresh green beans

Cream of mushroom soup

Soy sauce (the “secret” umami boost)

Black pepper

Milk

French-fried onions

3. Can I use fresh or frozen beans instead of canned?

Yes. If using fresh beans, blanch them in boiling water for 5–8 minutes or until tender-crisp. If using frozen beans, thaw and dry with a paper towel first or blanch for about 3 minutes.

4. How do I prevent a “soupy” or thin casserole?

Do this after draining the beans well. Extra moisture from canned or blanched beans is the chief culprit of a watery casserole.

5. Why is my topping soggy?

To keep French-fried onions crunchy, mix only part into the casserole and add the rest during the final 5–10 minutes of baking.

6. Can I make it without mushrooms?

Yes. You can replace cream of mushroom soup with cream of chicken, cream of celery, or a homemade white sauce (roux).

7. How do I make it ahead of time?

Assemble the casserole up to 2 days in advance and refrigerate. Bake covered first, then add onions at the end for crispiness.

8. How do I know when it’s done?

It is ready when the edges are bubbling and the onion topping is golden brown. This usually takes about 25–30 minutes at 350°F (175°C).

9. What are some popular variations?

Common upgrades include bacon, shredded cheddar cheese, garlic, or toasted almonds.

10. Can I make it in a slow cooker?

Yes. Cook on low for 2–3 hours, then add crispy onions just before serving to keep them from becoming soggy.

11. Is there a “secret ingredient” to make it better?

Soy sauce or Worcestershire sauce adds depth and umami. Some also add a pinch of brown sugar for slight sweetness.

12. How long do leftovers last?

Stored in an airtight container in the refrigerator, leftovers last up to 4 days.
