INSTANT POT FRENCH DIP SANDWICHES
Follow the steps exactly the same, the big difference is that you can actually sear the beef in the Instant Pot itself by setting it on Saute mode, then add the olive oil and when it's hot, add the beef to the IP and sear it on all sides. Remove the beef from the IP, then add the onion and garlic and saute them for about 3 minutes until soft. From then add the remaining ingredients, as in the slow cooker, close the lid and cook on high pressure for 100 minutes.
