Braised Lamb Shanks with Mushrooms and Marsala
Our IP Version of ROMANO’S MACARONI GRILL’S Braised Lamb Shanks with Mushrooms and Marsala. The copycat for the lamb shanks from this popular chain involves cooking the meat under pressure in a mushroom- marsala sauce. It’s a complex meal that’s truly dinner- party worthy. We suggest a Pinot Noir (or several) and maybe a less complexly flavored starter, like our version of Spago’s Butternut Squash Soup on page 50. At the restaurant, the dish is served with buttermilk mashed potatoes. Of course, you can simplify things and use more standard mashed potatoes or Applebee’s Garlic Mashed Potatoes from this book (page 267). However, we do have a great recipe for Leek and Buttermilk Mashed Potatoes in Instant Pot Bible: The Next Generation.

  • 1 medium yellow or white onionpeeled and chopped (1 cup)
  • 1 medium carrotpeeled and diced (1/3 cup)
  • 8 large cremini, Baby Bella, or brown button mushrooms,quartered
  • 3 medium garlic clovespeeled and minced (1 tablespoon)

  • 1tbsp Water

  • stemmed whole fresh sage leavesfor garnishing
Instructions
  1. Press SAUTÉ and set for MEDIUM, NORMAL, OR CUSTOM 300°F. Set the time for 20 minutes.
  2. As the pot heats, warm the oil in the insert set in a 6- or 8-quart Instant Pot. Add 2 of the shanks and brown them well on all sides, turning occasionally, about 6 minutes. Transfer the shanks to a nearby large bowl, add the remaining 2 shanks and brown them in the same way before getting them into that bowl.
  3. Add the onion, carrot, and mushrooms to the pot. Cook, stirring occasionally, until the onion softens, about 3 minutes. Stir in the garlic and salt until aromatic, about 20 seconds.
  4. Pour in the marsala wine and scrape up any browned bits on the bottom of the insert. Stir in the broth, then return the shanks (and any juices in their bowl) to the pot. Turn the shanks to coat them in the sauce, turn off the SAUTÉ function, and lock the lid onto the pot.
  5. MAX model: Set for PRESSURE COOK and set the pressure level to MAX. Set the time for 35 minutes with the KEEP WARM setting off.

    Other Instant Pot models: Set for PRESSURE COOK and set the pressure level to HIGH. Set the time for 45 minutes with the KEEP WARM setting off.
  6. When the pot has finished cooking, turn it off and let the pressure return to normal naturally, about 35 minutes. Unlatch the lid and open the cooker. Transfer the shanks to a serving platter or serving plates. Use a flatware tablespoon to skim the surface fat from the liquid in the pot.
  7. Press SAUTÉ and set for MEDIUM, NORMAL, OR CUSTOM 300°F. Set the time for 5 minutes with the KEEP WARM setting off.
  8. As the sauce comes to a simmer, whisk the cornstarch and water in a small bowl until smooth. Stir this slurry into the simmering sauce and cook, stirring constantly, until thickened, less than 1 minute. Turn off the SAUTÉ function and use hot pads or silicone baking mitts to transfer the (hot!) insert to a nearby wire rack to stop the cooking. Cool for a couple of minutes, then ladle the hot vegetable sauce over the shanks to serve alongside mashed potatoes. Garnish the plates with fresh sage leaves.
