Crockpot green bean casserole combines green beans, mushroom soup, milk, cheese, and french fried onion to create the classic holiday side dish right in your slow cooker. You will love this new way to create this classic dish everyone loves!

Crockpot Green Bean Casserole

Green bean casserole is a must make dish for the holidays and Sunday dinner! It is the perfect vegetable side dish that combines green beans with a creamy sauce and crunchy fried onions. Yum! The downfall is, especially on holidays, that this dish is taking up valuable oven space that you need for other dishes. That is why I love this Crockpot green bean casserole as well as the Instant Pot Green Bean casserole version!

You will love being able to dump all your ingredients in your slow cooker and cook this classic dish. As an added bonus, it stays warm way longer in the crockpot!

How to make crockpot green bean casserole

Prepare the slow cooker liner with nonstick cooking spray.
Place all ingredients into the slow cooker EXCEPT about 1 cup of the french fried onions. Mix together until well combined.

Cover the slow cooker and cook on high for 5 to 6 hours. Top with remaining french fried onions prior to serving.

Tips Tricks and FAQs

You can easily double this recipe in the crockpot. You might need to increase the cooking time a bit.
You can use canned green beans if you choose. I suggest using 6 cans.
You can easily keep this on warm after it cooks for up to 3 hours.
If you choose you can omit the parmesan cheese, but I highly recommend it as it adds so much flavor!

Storage

You will want to store your leftover green bean casserole in an airtight container for up to 4 days in the fridge.

Reheat

To reheat you can place the desired amount in a microwavable safe container and warm it to your desired temperature.

You can also warm this back up in the oven at 350° for about 30 minutes. Feel free to sprinkle more french fried onions on top with a few minutes left to add a little crunch!

Can I brown the onions before adding them?

Yes, you can easily make your onions even more crispy. Cook them over medium-high heat on the stove for about 3 minutes or until browned. Sprinkle over your casserole.

Can I make this ahead of time?

Yes! You can easily mix everything ahead of time and cover and place in the fridge for up to 2 days.
