For this recipe in the Instant Pot I used baby potatoes and baby carrots. I found by not using larger potatoes and carrots it cut down on the prep time (you know all that chopping and peeling). It's all a preference and to me a big time saver to use the smaller no-prep version. I just had to rinse and place them in the Instant Pot. I didn't need to peel and chop. It cut down about 10 minutes of time, and with two little ones to run after I'm all about quick prep! Here are the vegetables I like to cook with my corned beef. -Carrots -Potatoes -Cabbage -Onion -Garlic
