A Classic Comfort With a Holiday Soul
The Best Green Bean Casserole Recipe Begins With Tradition
This dish has a backstory that most people don’t think about while they’re piling it high on their plates. In 1955, a home economist at Campbell’s created a recipe that combined two common pantry items: green beans and cream of mushroom soup. It was meant to be easy, budget-friendly, and satisfying. That original version took off, showing up in newspapers, cookbooks, and eventually on just about every American holiday table.
Green bean casserole became more than just a dish. It was a symbol of tradition. Families might tweak it over the years, but the core has remained the same. It brings together simplicity, heartiness, and that savory crunch we all expect with the first bite.
Why This Recipe Stands Out From the Rest
There are countless ways to make green bean casserole, but this one holds its own. The cream of mushroom base gives it that rich, velvety texture, while a touch of soy sauce adds a quiet depth that makes the flavor more rounded. Some recipes go overboard with extras like cheese or bacon. This version stays true to the original while refining it just enough.
A big part of what makes this the best green bean casserole recipe is timing. You stir it once during baking. That simple step ensures even cooking and keeps the texture spot-on. And of course, those crispy onions on top? Don’t skimp. They’re the final, crave-worthy touch that turns this into a side dish people actually remember.

Simple Ingredients, Big Results
What Goes Into the Best Green Bean Casserole
You don’t need a long grocery list to make something unforgettable. This green bean casserole recipe keeps things simple, using ingredients you likely already have in your pantry. Let’s break them down.
- Cream of Mushroom Soup (10.5 oz) – This is the heart of the casserole. It creates a creamy, savory base that coats every bite.
- Whole Milk (¾ cup) – Thins out the soup just enough to create a smooth, pourable sauce.
- Soy Sauce (½ teaspoon) – A small addition with big impact. It deepens the flavor and balances the saltiness.
- Black Pepper (¼ teaspoon) – Just enough to add a little kick without overpowering the other ingredients.
- Green Beans (2 cans, drained, 14.5 oz each) – Whether you use cut or French-style, the texture should be tender but still hold its shape after baking.
- Crispy Fried Onions (1½ cups divided) – This is the golden crown of the dish. Fold some into the mixture for texture and add the rest on top before the final bake.
Now, let’s settle a common debate: soy sauce or Worcestershire? Both work, but soy sauce wins here for its cleaner umami profile. Worcestershire has more tang, which can compete with the mushroom flavor. If you’re short on soy sauce, a teaspoon of Worcestershire is an acceptable swap—just skip any extra salt.
Ingredient Swaps for UK Readers
If you’re making this outside the U.S., don’t worry. You can still enjoy the best green bean casserole recipe with a few local tweaks.
- Cream of Mushroom Soup: Look for condensed versions like Heinz or Baxters. If unavailable, you can make a quick substitute with sautéed mushrooms, butter, flour, and stock.
- Green Beans: UK tins are often 400g. Two tins (drained) work well, or use fresh green beans boiled until just tender.
- Crispy Fried Onions: If you can’t find French’s, check for brands like IKEA’s fried onions or supermarket own-label crispy onions in the salad toppings section.
Cooking across countries shouldn’t mean sacrificing flavor. This recipe holds up no matter where your kitchen is. What matters is that creamy bite with the crisp top—exactly what makes this casserole unforgettable.
How to Make It Just Right
Step-by-Step Breakdown for Perfect Texture
Making the best green bean casserole recipe doesn’t take much time, but it does reward attention to detail. Here’s how to get that perfect balance of creamy, crispy, and comforting.
Step 1: Prep the Base
In a mixing bowl, combine the cream of mushroom soup with whole milk. Whisk until smooth, then stir in the soy sauce and black pepper. This creates the velvety sauce that coats every bite.
Step 2: Add the Beans
Drain the green beans completely and add them to the sauce. Stir until they’re fully coated. This step matters—undermixed beans can lead to uneven flavor.
Step 3: Fold in Onions
Add ½ cup of the crispy fried onions and gently fold them in. These onions won’t stay crispy, but they add subtle texture and flavor throughout the casserole.
Step 4: Bake Once, Then Stir
Pour everything into a baking dish and smooth the top. Bake uncovered at 350°F for 30 minutes. After baking, take it out and stir gently. This distributes the heat and keeps the sauce from separating.
Step 5: Add Final Crunch
Top the casserole with the remaining fried onions. Bake for an additional 5 to 10 minutes, just until the topping turns a deep golden brown.
That’s it. No fancy tricks. No complicated techniques. Just a few steps that bring everything together the right way.
Make-Ahead and Freezer Instructions
One of the reasons this casserole shows up every holiday is how easy it is to prep ahead. You can assemble the whole dish, cover it tightly, and store it in the freezer for up to two weeks. Just don’t add the topping until you’re ready to bake.
When it’s time to cook, thaw it overnight in the fridge. Bake it according to the original directions and top it with fried onions in the last few minutes. You’ll still get that classic crispy finish, no shortcuts needed.
If you’re cooking for a crowd, making this casserole ahead of time means one less thing to worry about on a busy day. And it reheats beautifully, holding both flavor and texture.
