Introduction

The Green Bean Casserole is a timeless American side dish that first graced dinner tables in 1955, thanks to a clever home economist at Campbell’s Soup Company. Combining tender green beans, creamy mushroom sauce, and a golden topping of crispy fried onions, it quickly became a holiday favorite — especially for Thanksgiving.

Its comforting, creamy texture paired with the satisfying crunch of fried onions makes it one of those dishes that disappear fast from the buffet table. This recipe keeps the nostalgic flavor intact while using fresh green beans for a brighter taste and a little extra crispness.

Step-by-Step Preparation Method

Step 1: Preheat Oven

• Canned beans: Drain well and skip boiling.

Step 3: Mix the Sauce

• In a large mixing bowl, combine cream of mushroom soup, milk, soy sauce (if using), pepper, and half of the crispy onions.
