Bistro-Style Braised Short Ribs with Mushrooms
Although cooking beef short ribs in the Instant Pot cuts down on the time they need to braise, we haven’t shaved any time off any of the other steps in this fairly traditional recipe, even using a classic beurre manié (French, burh mahn-YAY, a butter and flour mixture) to thicken the sauce into silky richness. The meat will be so tender that you’ll barely need knives at the table, so the short ribs are best served in bowls.

Ingredients
  • 2 thin strips of baconchopped
  • 2 1/2tbsp butter1 1/2 tablespoons of it at room temperature
  • 3 1/2lbs boneless beef short ribs
  • 1small red onionchopped (1/2 cup
  • 3 1/2lbs brown cremini mushroomsthinly sliced
  • 1cup dry red winesuch as Cabernet Sauvignon
  • 1/2cup beef or chicken broth
  • 2tsp dried thyme
  • 1tsp dried sage
  • 1/2tsp table salt
  • 1/2tsp ground black pepper
  • 2 bay leaves
  • 1 1/2tbsp all-purpose flour
Instructions
  1. Press Saute, set time for 35 minutes.
  2. Melt 1 tablespoon butter in the cooker. Add the bacon and fry until crisp, stirring occasionally, about 4 minutes. Use a slotted spoon to transfer the bacon to a nearby large bowl.
  3. Add half the short ribs and brown them well on all sides, turning occasionally, about 10 minutes. Transfer these to that bowl and add the remaining short ribs, browning them in just the same way. Transfer these to the bowl, too.
  4. Add the onion and cook, stirring often, until softened, about 
3 minutes. Add the mushrooms and continue cooking, stirring occasionally, until they give off their internal moisture and that liquid evaporates to a glaze in the pot, about 5 minutes.
  5. Pour in the wine and scrape up the browned bits on the pot’s bottom. Turn off the SAUTÉ function and stir in the broth, thyme, sage, salt, pepper, and bay leaves. Return the short ribs, bacon, and any juices in that bowl to the pot. Stir well, then lock the lid onto the cooker.
  6. Option 1 MAX Pressure Cooker
    Press Pressure cook on Max pressure for 1 hour and 10 minutes with the Keep Warm setting off.
  7. Option 2 All Pressure Cookers
    Press Pressure cook (Manual) on High pressure for 1 hour and 30 minutes with the Keep Warm setting off.
  8. If you’ve used a pressure setting, when the machine has finished cooking, turn it off and let its pressure return to normal naturally, about 30 minutes.
  9. Option 3 Slow Cook
    Press Slow Cook option on High for 4 hours with Keep Warm setting off (or on for no more than 3 hours)
  10. Unlatch the lid and open the cooker. Find and discard the bay leaves. Use kitchen tongs and a slotted spoon to transfer the short ribs, bacon, and any vegetables to a serving platter. Tent with aluminum foil to keep warm. Use a flatware tablespoon to skim any excess surface fat from the sauce in the pot.
  11. Press Saute, set time for 5 minutes.
  12. As the sauce comes to a simmer, use a fork to make a smooth paste out of the flour and the remaining, room-temperature
 1 1/2 tablespoons butter in a small bowl. As the sauce simmers, whisk this flour mixture into the pot in dribs and drabs, just a little at a time, whisking until it’s all been added and the sauce has thickened, 1 to 2 minutes. Turn off the SAUTÉ function and pour the sauce in the hot insert over the meat and vegetables on the platter.
