How to Make The Best Green Bean Casserole
Preheat and Prepare: Start by preheating your oven to 350°F. Grab a 2-quart baking dish and lightly grease it to prevent any sticking. This will ensure your **The Best Green Bean Casserole** cooks evenly and comes out easily.
Whisk Together: In a large mixing bowl, combine the cream of mushroom soup and whole milk. Use a whisk to ensure a smooth blend these ingredients for the creamiest texture. Stir in the soy sauce and black pepper for that extra depth of flavor.
Add Green Beans: Drain the canned green beans and gently fold them into your soup mixture, making sure each bean is coated. This step is crucial as it combines all that creamy goodness, resulting in a rich flavor throughout every bite.
Incorporate Fried Onions: Now, it’s time to fold in half a cup of the crispy French’s fried onions. Feel free to be generous—these add a delightful crunch that complements the creamy beans perfectly. Plus, who doesn’t love crispy onions?

Add More Crunch: Sprinkle the remaining crispy fried onions on top. Return the dish to the oven and bake for an additional 5-10 minutes, until the onions are golden brown and crispy. You’ll know it’s done when the top is as satisfying to look at as it is to eat!
