Instant Pot Green Bean Casserole with Cheese

My favorite time of year is finally here. Yes, I love every single thing about the holiday season. Most of all I love all of the yummy food and treats. This green bean casserole recipe is not just for the holidays. This dish is so scrumptious you will likely want to eat it any time of the year.

Why did I use an Instant Pot? Well because I wanted to. Surely, you can make green bean casserole without an Instant Pot. Just like you make a ton of other recipes without an Instant Pot. I love using my Instant Pot because it is convenient for me and my lifestyle. Pressure cookers also do a great job of producing immense flavor. A lot of my fellow Instant Pot fans will agree with me there.

I like being able to set something to cook and then walk away. The experience is different than a slow-cooker because I don’t have to wait several hours for the meal to complete. I can maybe do a load of laundry and come back or cook other side dishes or meals in the meantime.

These perks come in really handy for holidays like Thanksgiving and Christmas. I am usually responsible for a few different menu items for our family holiday celebrations. Cooking could very well turn out to be an all day event for several different reasons, varying oven temperatures required for baked items, the time it takes to properly prep certain dishes, etc. Having a stand-alone appliance can help out a lot.

This green bean casserole may be a little different than what you are used to. I added shredded cheese. I couldn’t resist! If you are dairy-free or vegan, simply omit the ingredient. The casserole is still such an amazing side dish. I love to remix my favorite childhood recipes from time to time.

  • Bake for 20-25 minutes.
  • Remove the dish. Top with the french fried onions. Bake for an additional 5 minutes.



I didn't add any water or broth to the Instant Pot for the green beans. The soup was enough for me. If you wish you can add a cup of water or broth and drain it before baking
I purchase blocks of cheese and do the grating and shredding on my own. The cheese melts a lot better this way, vs purchasing pre-shredded cheese.

Love the recipe! If using FROZEN Green Beans, would there be any changes to the pressure cooking times? If adding a cup of water to the bean/soup mixture and we “drain” after pc-ing, as you suggest, wouldn’t we be also draining all the flavor from the mushroom/ bean mixture ? Could we just saute to reduce, or would that make the green beans mushy? While I do have a few of the older models of IP’s, this recipe sounds ideal to try out in my New IP Duo Crisp! Thanks, in advance and Happy Holidays!

I wouldn't change the time for pressure cooking. Typically, using frozen will just take longer for the pot to come to pressure. I would follow the recipe as it's written, but if you have concerns you can try it your way without draining.

I assume that you use a can of undiluted condensed cream of mushroom soup, correct? Your directions say add the soup.


Sunday 3rd of March 2019

Correct. You don't need to dilute the soup.
