Grandma's Secret That Changes Everything
Here's the game-changing secret that transforms ordinary Instant Pot French Onion Pot Roast into an extraordinary family treasure: add a tablespoon of Dijon mustard and a splash of Worcestershire sauce to your cooking liquid. This simple addition creates incredible depth and complexity that elevates every bite. The mustard adds subtle tang while the Worcestershire provides umami richness that makes the Instant Pot French Onion Pot Roast taste like it's been slow-cooking for hours.
The second secret involves the resting period after cooking. Instead of slicing immediately, tent your roast with foil and let it rest in its own juices for 15 minutes. This allows the meat fibers to relax and reabsorb moisture, ensuring every slice of your Instant Pot French Onion Pot Roast stays incredibly tender and juicy. These simple techniques have been passed down through generations and make all the difference in achieving restaurant-quality results at home.
