A 6 quart or larger Instant Pot will work great for this recipe.
For best results, serve this dish close to when it’s cooked so that the green beans stay nice and fresh. You can keep it warm in the Instant Pot for 30 minutes to an hour til you are ready to serve. Leftovers will keep well for 2 to 3 days covered in the fridge.
The best way to reheat this is in the oven in the casserole dish you are going to serve it in. Cover the dish with foil and place in the oven at 350F and cook for 15 minutes or so until warmed through.
You can freeze this dish, but it’s best to not add the fried onion topping as this will get soggy. Place the green beans and the creamy sauce into a casserole dish, cover with foil and freeze. Thaw it at room temperature before reheating and adding the onions to serve.
This Instant Pot green bean casserole is the perfect addition to serve at your Thanksgiving dinner. Serve it alongside other favorites like….
- Air Fryer Garlic Rosemary Turkey Breast
- Roast Turkey Breast
- Honey Baked Ham (Oven)
- Herb Roasted Potatoes
- Mashed Potatoes
For me, my Thanksgiving meal is not complete without a classic green bean casserole! This comes out so well, and I love that it makes room in my oven!
All the Tips and Tricks
How to Cook Thanksgiving Turkey!
Everything you need to know for Thanksgiving entertaining.
- The fried onion topping is optional, though it’s a must for me!
- Trim the ends of the green beans, the stalks can be quite woody and stick like.
- For non mushroom lovers, you can substitute the mushroom soup with condensed cream of chicken soup.
This came out so good! I promise you everyone will be asking for this recipe!
Can I use canned or frozen green beans?
I prefer to use fresh beans, but you can use canned or frozen if you have then to hand – I find that frozen yield better results than canned. If using frozen, thaw them first by running them under cold water before using.
Can I use homemade cream of mushroom soup instead?
I love the convenience of using canned condensed mushroom soup for this dish, as it’s just the right consistency. You can use homemade, but make sure it’s thick so that you don’t have a watery casserole.
