While many green bean casserole recipes call for soy sauce, I prefer Worcestershire sauce in mine. It adds bold, savory flavor with a hint of tang that perfectly complements the creamy mushroom sauce, tender green beans, and crispy French-fried onions.

For a complete Thanksgiving spread, serve this casserole alongside a Cheesecloth Turkey and other comforting sides like Party Mashed Potatoes, Corn Casserole, and Creamed Spinach. These easy-to-make sides will round out your holiday table with delicious flavors everyone will love!

All the ingredients for green bean casserole, including 2 cans of cut green beans, cream of mushroom soup, milk, Worcestershire sauce, garlic powder, salt, pepper, and crispy fried onions.

Green Beans – Canned cut green beans or canned French style green beans are the most convenient option. However, fresh green beans or frozen green beans can also be used. Instructions for all options will be included in the recipe card below.
Cream of Mushroom Soup – Adds creaminess and flavor. You can substitute with cream of celery or cream of chicken soup for a different flavor profile.
Milk – Thins the soup for a smoother sauce. I recommend whole milk but you can use any milk or dairy-free alternative, like almond or oat milk.
Worcestershire Sauce – Adds bold, savory flavor with a hint of tang. Soy sauce can be used instead if you prefer, but it will alter the flavor slightly.
Garlic Powder – Provides a subtle garlic flavor. Feel free to add fresh minced garlic for a stronger taste.
Crispy Fried Onions – The crunchy topping adds texture. You can substitute with homemade fried onions or breadcrumbs for a different crunch.
