Brittany Williams on Instagram: "This simple pressure cooker pot roast has been a staple in our home for the last 10 years. Traditionally, for a pot roast to come out tender and flavorful, it has to slowly cook in the oven or slow cooker for hours. With the pressure cooker, the cooking time is reduced to 90 minutes, even if the roast is frozen— and it still comes out just as tender and flavorful as expected. Comment “pot roast” and I’ll send the recipe to your messages!"
