How do you make Instant Pot Roast with Mashed Potatoes?

Easy! First up, the mashed potatoes. Cut and peel your potatoes. Place the potatoes in your Instant Pot. Add water until just covering the potatoes. Cover with the pot lid and pressure cook for 10 minutes. Strain and mash the potatoes. Then add oat milk, salt, pepper, and garlic cloves. The potatoes are already done! Pour them into another dish and set aside. Clean out your Instant Pot for round two! 

Round two is the pot roast. Set your Instant Pot to “sauté mode (high)” and add olive oil. Add your chuck roast and sear each side. This should take about 2 minutes. Once the roast is seared, add beef broth, garlic cloves, and half of the prepared onion. Place rosemary sprigs on top of the roast, cover, and set to “pressure cook” mode for 1 hour and 30 minutes. When time is up, manually release the Instant Pot pressure. 

Now, for the vegetables – the home stretch! Add carrots and remaining onion. Cover with lid and pressure cook for 1 minute. Remove the roast and veggies from the pot and discard rosemary sprigs. Place the food on a plate or dish. Get ready for the gravy, baby! Heat the roast’s juices in “sauté mode.” Combine arrowroot powder and water in a small bowl to make a slurry. Add your slurry to the heated juices in the Instant Pot and stir until thick. Turn off the heat. Transfer the gravy or leave it in the pot until cool. 

There you go. One and done instant pot roast dinner (or lunch later)!
