This is also known as “green bean bake,” or “string bean casserole” but regardless of what you call it, all I know is that this dish is a staple at many Thanksgiving gatherings. It is also the best side dish anytime of year. No need to save it for a special holiday! It’s rich, creamy, and comes together so quickly.

Storage

Refrigerate– Store leftovers in a sealed container in the fridge for up to 2 days but the fried onions won’t be as crispy any more.

Freeze- I don’t recommend freezing leftovers since the milk mixture has a tendency to separate upon thawing.

Reheat– In the microwave or stovetop, noting that the fried onions will no longer be crispy.

Variations

Fresh green bean casserole with cheese– Use fresh green beans that are washed, trimmed and patted dry. Also, add shredded mozzarella or cheddar, Parmesan, Gouda, or even Swiss cheese in the mixture as well as the topping.

Loaded green bean casserole– Add bacon crumbles and top it with lots of fresh chives and shredded cheese.

Add proteins– Such as cooked ground beef, shredded chicken, sliced sausages, cubed ham. All the proteins should already be cooked through before being added.

Healthy vegan green bean casserole (dairy free)- Use vegan butter and vegan cream of mushroom soup, and almond milk in place of whole milk.

Use cream of chicken– In place of cream of mushroom soup, if you prefer that flavor.

Make it gluten- free– Use gluten free fried onions, and coconut aminos instead of soy sauce.

Add seasonings– Such as Italian, Mexican, Cajun, or Greek blend for a flavor twist.

Make it spicy– Add crushed red chili flakes for a kick,.

Add nuts– Such as toasted walnuts, pecans, or almonds to the topping. It adds a wonderful crunch.

Add other vegetables– Such as caramelized onions, broccoli or red bell peppers.

Other topping ideas–The classic choice is crispy fried onions but you can try a mixture of cornflakes and butter or crumbled butter crackers or Ritz crackers. Get creative and have fun cooking!

Tips And Techniques

Fresh green beans vs. Canned green beans– I used canned green beans to save time, but you can use fresh green beans that are washed and trimmed just as easily. The cook time will be slightly longer, when using fresh beans.

Cream of mushroom soup substitute– You can use cream of chicken, cream of celery, or even sour cream with finely diced mushrooms, if you prefer.

Use whole milk– Because this adds richness, creaminess, and creates the best overall flavor.

Drain and rinse canned green beans– This washes off all the preservatives, and also ensures that there is not too much liquid. Furthermore, it prevents the casserole from getting soggy.

Adjust seasoning– Add more or less soy sauce, garlic powder, onion powder based on your personal preference.

Bake uncovered– This helps provide the best texture. If you cover it, the excess liquid does not evaporate and it creates a soggy watery mess.

How to fix soggy casserole? Bake uncovered until excess liquid is reduced. Also, be sure to measure your ingredients properly before you start cooking to prevent this from happening in the first place.

How to fix dry casserole? Add some more milk or broth and bake for a few additional minutes.
