Instant Pot® Lamb Pot Roast

Instant Pot® Best Lamb Neck Pot Roast Recipe


I love my Instant Pot® (IP) and I know many of you do, too, so I’m going to include some IP recipes for you for those days you decide to cook at the last minute, or you just need a fairly quick weeknight supper. I have found no difference in quality between cooking methods with this recipe, whether you use your Dutch oven on the stove top, in the oven, or braise in your slow cooker all day, the meat is tender and the broth is so tasty. However, since all the steam stays in the IP instead of evaporating with other cooking methods, all that wonderful flavor-enriched aroma that otherwise wafts through the house stays right in the IP, and perhaps that makes this method a bit more flavorful. That’s my testimonial, and now here’s my delicious recipe for our meaty lamb neck roasts made into the best lamb pot roast ever. (Continue reading after the recipe for step by step pictures and tips.) Lamb neck roasts are available by appointment here at the farm or at the Matthews Community Farmers Market on Saturday mornings. While supplies last.

Servings 6


  • Pressure Cooker


  • 1-2 whole Fox Trot Farm Lamb Neck Roasts, about 3 pounds total
  • 1 tbsp. neutral oil
  • Salt & Pepper
  • 2 cups peeled, diced carrots
  • 1 cup diced celery
  • 2 cups diced onions
  • 2 tsps. minced garlic
  • 1 tsp. dried thyme leaves
  • 1 whole bay leaf
  • 3 tbsp. tomato paste
  • 1 cup dry red wine (such as Cabernet Sauvignon or Pinto Noir)
  • 1 tbsp. low sodium soy sauce (optional but will deepen flavor)
  • 2 tsps. Better than Bouillon® beef bouillon
  • 2 cups water (alternately, substitute 2 cups beef broth or stock for bouillon & water)


  • Remove the butcher twine from the neck roasts and discard, rinse the roast and pat dry.
  • Drizzle oil into Instant Pot® (IP) and press “Sauté.” (Mine is a six quart brand name Duo model.)
  • When oil is shimmering, add the lamb. Brown on all sides (when brown the meat will release easily from the pot). Remove from pot to a plate while you continue with the recipe.
  • To the pot, add carrots, celery, onions, and garlic. Sprinkle dried thyme, salt and pepper over and sauté and stir till veggies are coated with the oil and are heated. Stir in the bay leaf. As the veggies release their liquid, scrape up the bits of browned beef from the pot. A wooden spoon is good for this.
  • Clear a space in the center of the pot and add the tomato paste. Continue to sauté till the tomato paste is bubbling, and then stir it into the vegetables.
  • Add the dry red wine and soy sauce and stir to combine with the vegetables. When the mixture comes to a boil, stir while simmering rapidly for 3 minutes to cook off some of the alcohol.
  • Add the bouillon and water (or broth/stock) and bring back to a boil.
  • Return the meat to the pot. Lock the cover and set to high pressure. Set timer for 75 minutes. Allow the pressure to release naturally, about 30 minutes. Meat should be tender when pierced with a fork. If not, cook for another 10 minutes under pressure and allow natural release for 10 minutes, then quick release.
  • Remove the roast to a platter to allow to cool till you can handle it.
  • Meanwhile, skim the fat off the broth in the IP. (Important step)
  • Taste for seasoning and add salt and pepper as desired.
  • Bring to a simmer and thicken with a slurry made from 2 tablespoons of cornstarch mixed with enough water to make a loose paste. Simmer till clear and glossy. Turn off IP and cover with lid to keep warm.
  • Pull the meat from the bones and stir the meat into the vegetables and sauce. Serve over rice, mashed potatoes, or noodles and enjoy!

Comparison of lamb meat to bone in the Fox Trot Farm Lamb neck roast cooked in the Instant Pot®

I’ve deboned the roast. From a 3# roast, I got 1 1/2 # of meat and the small plate of bones. This is very easy to debone since the bones are a good size. The meat is perfectly tender, juicy, and flavorful.

I can’t wait for you to taste all the rich flavors in this pot roast!


  1. If you have less than the three pounds of lamb necks (I have two necks, total two pounds), would this reduce the pressure cooking time?

    • You can always try it for 60 minutes, QR, then check it. If it needs more time, it will only take a few minutes to come back up to pressure. The meat should easily pull off the bone.

  2. I had never made a lamb neck dish but saw it in the lamb section at our local Publix. Follow the recipe and you will be rewarded with a delicious meal. I added a couple of 6″ stems of fresh rosemary and used whole baby carrots. Spooned the fall-apart meat, vegetables and gravy over hot buttered noodles. Superb.

  3. I bought the lamb neck toast at the Waxhaw market today. I am making this tomorrow cant wait
