How to Make Campbell’s Green Bean Casserole

Preheat your oven to 350°F and prepare a 9×9 baking dish by greasing it lightly. This ensures your casserole doesn’t stick and bakes evenly.
Combine the ingredients in a large bowl. Mix the green beans, condensed cream of mushroom soup, milk, soy sauce, black pepper, and 2/3 cup of the French fried onions until well blended.
Spread the mixture into your prepared baking dish evenly. This layer acts as the creamy goodness that pairs so well with the crisp topping.
Bake the casserole for 25 minutes until it’s hot and bubbly, with edges starting to lightly brown. The smell will be irresistible!
Sprinkle the remaining 2/3 cup of French fried onions on top and return to the oven for an additional 5 minutes. This adds a delightful crunch that contrasts with the creaminess.

Optional: Serve with fresh parsley for a pop of color!

Campbell’s Green Bean Casserole Recipe FAQs

How do I select the best green beans for my casserole?
Absolutely! When choosing green beans, look for firm, vibrant green beans that are free of dark spots or blemishes. If using fresh beans, snap off the ends and cut them into equal pieces for even cooking. If opting for canned, make sure they are low-sodium for a healthier option.

How should I store leftover Campbell’s Green Bean Casserole?
To keep your casserole fresh, store any leftovers in an airtight container in the refrigerator for up to 3 days. When ready to enjoy, reheat it in the oven at 350°F or in the microwave, covering it to prevent it from drying out.

Can I freeze Campbell’s Green Bean Casserole for later?
Very! Freezing is a fantastic option. Wrap the casserole tightly in plastic wrap or aluminum foil, then place it in an airtight container or freezer bag. It can last up to 3 months in the freezer. When ready to serve, thaw it overnight in the refrigerator, then bake at 350°F for about 30-40 minutes until heated through, covering with foil to avoid browning.

What if my casserole turns out too soupy?
If your casserole ends up a bit soupy, try mixing in a tablespoon or two of breadcrumbs or extra French fried onions to absorb some of the excess moisture. You could also bake it a few minutes longer at a slightly higher temperature. Remember that a well-measured ratio of ingredients is key; be cautious with the liquid, especially if you’re adding milk or additional soup.

Is this recipe suitable for gluten-free diets?
Yes! You can easily make Campbell’s Green Bean Casserole gluten-free by swapping out the condensed cream of mushroom soup for a gluten-free version or by making your own with gluten-free flour. Be sure to check that your French fried onions are also gluten-free, as some brands contain wheat flour. This way, everyone can enjoy its deliciousness!

Can pets share this casserole with me?
It’s best to refrain from sharing Campbell’s Green Bean Casserole with pets. Ingredients like soy sauce and certain seasonings aren’t healthy for them. However, fresh green beans are generally safe for dogs, so consider offering them a plain green bean as a treat!
