Pro Tips & Tasty Tweaks
After making this Campbells Green Bean Casserole for decades, I’ve picked up a few secrets to make it truly your own. Here are my favorite ways to add a little personal touch to this beloved classic.
- Flavor Swap: For a richer, umami kick, try using a dash of Worcestershire sauce instead of soy sauce. It’s a small change with a big impact.
- Diet Tweak: To make a lighter version, use a low-fat cream of mushroom soup and low-fat milk. The result is still wonderfully creamy and satisfying.
- Prep Fix: The key to preventing a watery casserole is to drain those green beans extremely well. I even pat them dry with a paper towel for good measure.
- Storage Tip: If you have leftovers, they reheat beautifully in the oven to keep the onions crisp. Just cover with foil and warm at 350°F for about 15 minutes.
Healthier Alternatives for Campbells Green Bean Casserole
I often get asked, “Can I make a healthier Campbells Green Bean Casserole?” and the answer is a resounding yes! This dish is wonderfully adaptable. For a fresh green bean casserole feel, you can absolutely use fresh steamed green beans instead of canned.

How to Serve Campbells Green Bean Casserole

Frequently Asked Questions
What is the original recipe for Campbell’s green bean casserole?
The original recipe, created by Campbell’s in 1955, is very similar to this one! It was designed to be an easy, convenient dish using pantry staples like cream of mushroom soup and crispy fried onions. It’s a testament to how a simple recipe can become a timeless classic.
How do you keep green bean casserole from getting watery?
The key is to drain your green beans extremely well. I give my canned beans a good rinse under cold water and then pat them completely dry with a few paper towels. This extra minute of effort ensures your casserole is creamy, not watery.
Can you make Campbell’s green bean casserole ahead of time?
Absolutely! You can assemble the casserole completely (without the final onion topping) a day ahead. Cover it tightly and refrigerate. When you’re ready, bake it as directed, adding a few extra minutes to the initial bake time since it’s cold, then add the onions for the final 5 minutes.
What can I use instead of fried onions in green bean casserole?
If you’re out of fried onions, you can make a quick crispy topping with crushed butter crackers or panko breadcrumbs tossed with a little melted butter. Bake until golden for a delightful crunch that’s a lovely twist on the original.
How long do you bake a Campbell’s green bean casserole?
You’ll bake it for 25 minutes initially, then after adding the onions, for a final 5 minutes. So the total bake time is 30 minutes. It’s a relatively quick bake, which is part of what makes this recipe so wonderfully easy.
Is Campbell’s green bean casserole gluten free?
Traditionally, no, as both the cream of mushroom soup and the French fried onions contain gluten. However, you can easily make a gluten-free version by using a certified gluten-free cream of mushroom soup and gluten-free fried onions, which are now available in many stores.
Can you freeze a green bean casserole after baking it?
I don’t recommend freezing the assembled casserole after baking. The creamy sauce can separate and become grainy, and the onions will lose all their wonderful crunch. It’s truly best enjoyed fresh from the oven.
What goes well with green bean casserole for dinner?
It’s the ultimate comfort food side! It pairs perfectly with roasted turkey, baked ham, meatloaf, or even a juicy roast beef. For a simpler meal, I love it with a baked chicken breast and some fluffy dinner rolls to soak up every last bit of that creamy sauce.
How do you make green bean casserole without mushroom soup?
You can create a delicious from-scratch sauce! Sauté sliced mushrooms in butter, make a roux with flour, and whisk in milk or broth until thickened. Season well with garlic, onion powder, and a dash of soy sauce for that classic umami flavor.
