Instant Pot Green Bean Casserole (2024)

Here’s an Instant Pot green bean casserole from scratch: fresh green beans, real mushrooms, and a crumbled potato chip topping!

This ain’t your mama’s green bean casserole. Nope, this one’s a fresh spin made all from scratch. It’s got crisp tender green beans and real mushrooms. The creamy sauce coats each of the beans, but isn’t gloppy. And it’s got a new take on the traditional fried onion topping! I first discovered green bean casserole when I moved to Indiana 15 years ago. While it wasn’t my tradition growing up, I’ve grown to love this savory dish…but have always wanted to make a “from scratch” version. So we present, our updated version of our holiday favorite made in a pressure cooker!

A gourmet spin on green bean casserole

Did you know green bean casserole was an invention by Campbell’s Soup? (I had no idea.) It was invented to use their cream of mushroom soup, and paired it with canned green beans and crunchy fried onions. Truly, an odd combination. But it works! Americans have been making it ever since, mostly for Thanksgiving and other holidays.

What makes this Instant Pot green bean casserole better than the rest? Well, this one is all about flavor. Here’s what we’ve done to this Instant Pot green bean casserole to give it a modern spin:

• Fresh green beans. No canned beans here! They come out crisp tender, with just the right amount of texture.
• Real mushrooms and cream. No need for canned soup, either! This one uses real mushrooms and cream to get big flavor. (We’ve thrown in a little Parmesan cheese too, because: why not?)
• Gourmet potato chips! Yep, instead of the signature crunchy onions Alex had the idea to use crunched up sour cream and onion potato chips. It really works, and plus you have leftovers to munch on (instead of random onions that gather dust in your cupboard).

What people are saying…

People have been loving this Instant Pot green bean casserole! Here’s what one recipe tester had to say:

• “It’s better than I expected! I’m used to the can of soup type of green bean casserole, so I wasn’t sure this would be as flavorful or rich. But it’s even more so! I will be making this for Thanksgiving for years to come, especially because it’s so easy in the Instant Pot!” -Kristi

How to make Instant Pot green bean casserole: a tutorial

So, how does it all work in a pressure cooker! It’s pretty simple to make Instant Pot green bean casserole. Here are the basic steps for how it’s done (see the full recipe below):

Step 1 Prep the veggies.

Trim the beans (here’s a shortcut!). Chop the mushrooms and shallot.

Step 2 Saute the mushrooms and shallots.

Use the Instant Pot saute function to saute the mushroom and shallot in olive oil for about 6 minutes. Then add the green beans and water.

Step 3 Pressure cook on High for 1 minute.

Pressure cook for 1 minute. Note that it takes about 5 minutes for the Instant Pot to come up to pressure. Then do a quick release.

Step 4: Saute the sauce.

Stir in the cream, Parmesan cheese, garlic and spices. Use the Saute function again for about 1 minute until a thick sauce forms. Transfer to a serving dish, top with crushed chips, and serve!

What kind of Instant Pot to use?

All pressure cooker brands vary! Here’s the brand we use: anInstant Pot 6 Qt Programmable Pressure Cooker. This recipe is customized for a 6 quart pressure cooker. We also can’t speak to other brands and types of pressure cookers. For example, Instant Pot Mini works differently, so use it at your own risk!
