Alright everyone: we’re just four short days away from the largest feast of the year! Are you ready? Who’s doing all the cooking– is it you, or a family member? I can’t wait to enjoy all my favorite Thanksgiving dishes with family this year <3

I’ve been doing an Instant Pot series for the whole month of November! It’s time for the FINAL recipe. In case you missed it, so far we’ve done Green Beans with Mushrooms & BaconHoney Herb Carrots, Pumpkin Mashed Potatoes, and Cranberry Sauce. I’m all about making Thanksgiving a little easier on all of us. The Instant Pot (affiliate link) is my FAVORITE new kitchen appliance.

Here’s a video that shows how to make Instant Pot Sweet Potato Casserole: 

The sweet potatoes are steamed in the Instant Pot in 8 minutes, and then you can add the rest of the pie ingredients directly into the instant pot after you drain the potatoes. You don’t have to use any additional bowls or pots and pans! After you mix everything up in the IP, you add it to the baking dish and top with nuts and marshmallows.

This Instant Pot Sweet Potato Casserole bakes in the oven for 30 minutes and then it’s ready for the feast! I love the toasted marshmallows and the crumbly walnuts with the brown sugar and melted butter. So delicious!
