Notes
You can make a gravy by stirring 1 tablespoon cornstarch in with 1/2 cup of water. Then whisk it in with the steak juices. Switch the Instant Pot to the sauté setting and cook for 3-5 minutes until the sauce has thickened. Refrigerate the leftovers in an air tight container for up to 5-7 days.
