What do I do if my green bean casserole is too watery?

When you use my super easy green bean casserole, you'll never have to worry about runny or watery casserole again! The quick roux makes the cheesy sauce perfectly creamy, thick, and delicious in no time. Don't be scared off by the thought of making a roux - it's literally just butter and flour and this recipe makes it foolproof!

Can you reheat green bean casserole?

Yes! If you have leftover bacon green bean casserole, just bake it in a 350-degree oven for about 20 minutes or until heated through. You can also zap it in the microwave for a minute or so depending on how much you have left, but to heat it through more evenly, bake it in the oven.

Will my green bean casserole thicken?

Yes! Your green bean casserole will thicken a bit as it sits. You can pop it back in the oven for a few minutes to help it loosen up. Basically, it just needs to warm through and the sauce will get creamy again.

Ingredients

Scale

6 tablespoons butter
32 oz. frozen green beans
16 oz. bacon, cooked and crumbled
1 small yellow onion, diced
4 cloves garlic, thinly sliced
4 tablespoons flour
2 cups whole milk
8 oz. sharp white cheddar
6 oz. French fried onions
Kosher salt
fresh cracked pepper

Instructions

Preheat oven to 400 degrees and arrange slices of bacon on a foil-lined baking sheet.
Bake bacon for about 20-25 minutes or until it’s crispy. Transfer cooked bacon to a paper towel-lined plate to cool. Then crumble.
Add butter to a large sauté pan and heat over medium heat.
Add diced onion along with a couple large pinches of salt and pepper. Cook, stirring frequently for 5 minutes. Reduce heat to medium low if the butter is sputtering too much or if the onions start to turn brown.
Add garlic and cook, stirring frequently for 1 minute.
Add flour and cook, stirring frequently for 1 minute.
Slowly stir in whole milk along with a couple large pinches of salt and pepper until the mixture becomes smooth and creamy. Cook for about 3 minutes, stirring frequently until the milk is warmed through a bit and just starts to simmer.
Add shredded cheese, reduce heat to low stirring until melted and the sauce begins to thicken.
Stir in frozen beans and bacon along with a few large pinches of salt and pepper. Reserve a small handful of bacon for garnish.
If you’re using this type of large saute pan, you can put it straight into the oven. If you’re not using an oven-safe pan, you can transfer the mixture to a 9×13 baking dish. Bake uncovered at 400 degrees for 15 minutes or until heated through.
Top casserole with French fried onions and reserved bacon, then bake for another 5 minutes.
Let cool just a few minutes and then dig in and enjoy!

Notes

If your family isn’t into onions, try dicing them very finely. They will blend in almost seamlessly with the sauce so your picky eaters won’t notice, but your green bean casserole will still have the same great flavor!
Frozen or fresh green beans are going to give you the best flavor and texture for this dish. Canned green beans will not work quite as well because they’re already cooked. They’ll end up being mushy in this casserole and won’t give you quite as much flavor.
To make this green bean casserole vegetarian, just skip the bacon! The flavors will still be delicious without the bacon.
