Instant Pot Twice Baked Potato Casserole Recipe

I just got an Instant Pot and I’ll tell you what, it was love at first dish!

I put off getting one forever because I didn’t believe it could live up to all the hype. Boy, was I wrong!

It cooks things so incredibly fast and you don’t sacrifice flavor! Seriously, I’ve made recipes that are supposed to slow cook for 6+ hours and done them in the Instant Pot in only 1! The meat came out super juicy and tender. Magic!

One of my favorite new things to make in the Instant Pot is Twice Baked Potato Casserole. This dish is already incredibly delicious, and the instant pot makes putting it together a breeze.

Recipe for how to make twice baked potato casserole in the Instant Pot

I simply quarter red potatoes (leaving the peels on) and add them to the Instant Pot with water, peeled garlic, and a stick of butter. Then I cook them on high pressure for just 6 minutes.

After that, you can easily mash the potatoes with a potato masher or hand mixer. Then mix them with the wonderful cheese, chives, milk, and place in a pan to bake.

This is a great make-ahead holiday or potluck dish that can be prepped up to this point, then easily be finish in the oven when you arrive at your destination.

If you like to meal prep, it can also be easily put in the freezer at this stage. Just take it out and bake when you are ready to serve.

I’ve heard nothing but praise every single time I served this side dish. It’s so easy that I truly believe anyone could make this crowd pleaser!
