INGREDIENTS

For the lamb:

For the gravy:

▢ 3 tablespoons salted butter
▢ 2 tablespoons all-purpose flour
▢ salt and pepper

INSTRUCTIONS

Cooking the lamb:

Remove any netting from the lamb and pat dry with paper towels. Season all over with salt, pepper, thyme, and garlic.
Select the sauté mode on the pressure cooker for medium heat. Add 1 tablespoon olive oil to coat the bottom.
When the pot is hot, add lamb leg and brown all over, a few minutes per side. Transfer the lamb leg to a large plate.
Add white wine and let it simmer for a few minutes while you scrape up all brown bits stuck to the bottom of the pot. Turn off the sauté mode.
Add water. Transfer the lamb back to the pot. Secure and seal the lid. Cook for 90 minutes at high pressure, followed by a 20 minute natural release. Manually release remaining pressure using the steam handle.
While waiting for the natural pressure release, preheat the oven to 400 F.
When the pot has depressurized, transfer the lamb to a baking dish, leaving the liquid in the pot.
Drizzle 1 tablespoon olive oil on top of the lamb. Bake the lamb until nicely browned on top, about 15 minutes.

Making the gravy:

While waiting for the lamb to bake, pour all of the liquid from the pressure cooker pot into a bowl. Let the fat rise to the top and use a spoon to skim off the fat. Measure out 2 cups of liquid and discard the rest.
Select the sauté mode on the pressure cooker for medium heat. Add butter and stir until melted.
Add flour on top of the melted butter. Stir together for a minute.
Gradually pour in reserved 2 cups of liquid as you stir together. Continue stirring until it thickens to your desired gravy consistency, about 5 minutes. Add salt and pepper to taste.
Serve sliced lamb with gravy poured on top. Optionally garnish with chopped parsley.

NOTES & TIPS

Boneless leg of lamb is a great alternative to serving turkey or beef for the holidays. I prefer the texture and taste of lamb, and cooking a boneless leg is a lot more manageable than roasting a whole turkey. You can serve this for Christmas dinner or any other special occasion, and I usually pair it with some mashed cauliflower (as photographed here) or greens for a low carb meal.

Pressure Cooking. The pressure cooker is the easiest way to cook a leg of lamb, as it would take more than twice as long using a conventional method like roasting, and five times longer using a slow cooker. You’ll get the same deliciously tender, shredded meat either way, but far faster if you use a pressure cooker. I love the resulting juicy and moist leg meat, and you can easily whip up a simple gravy using the lamb drippings.

Utensils. I recommend preparing some heavy duty utensils for handling the lamb leg prior to starting the recipe. Weighing about 3-4 pounds, the leg is heavy and you’ll need to transfer it to/from the Instant Pot as well as for turning the meat while searing all sides. I prefer using two sturdy wooden utensils to support the leg as I move it about.

Oven Step. The oven step at the end of the recipe is optional. The lamb leg is tender after pressure cooking, and the oven time simply gives it a nice browning all over. I don’t consider this step to be extra work or time added, because you’ll need time to make the gravy, which can happen when the lamb is browning in the oven. The oven preheating can occur at the same time the Instant Pot is depressurizing.

Leftovers. Store leftover lamb and gravy separately. To reheat, warm them separately on a pan until heated through. You can also microwave them without much detriment to the tender texture of the lamb.

Nutrition Estimate. The nutrition estimate includes all of the lamb; in reality much of its rendered fat is discarded.

Low Carb. As a low carb eater, I hardly ever have to dig into the farthest reaches of my pantry to grab the flour. But I make exceptions for recipes like this one because only a very small amount (2 tablespoons of flour) is needed to make the gravy. Each tablespoon of flour has about 6g net carbs for a total of 12g for this recipe, which isn’t much when you divide it among four servings. For a low carb diet, it’s the total consumed net carbs that counts, not the particular ingredients used. Gravy needs the starch that comes with flour, and low carb replacements like xanthan gum aren’t as readily available.

Wonderful. A thought for the gravey—l put a small amount of carrot, celery, onion and garlic in the bottom of the pot then purée the liquid for the gravey—no flour needed. I’ve used this method for turkey gravey. Much more flavor than flour

Gravy was awesome! Used apple cider in place of wine. Used a bone-in leg and it turned out great.

Samantha

What type of cooking wine do you recommend?

Julia

I recommend using a dry white wine, like Sauvignon Blanc.

Do we need to place the lamb in the bottom of the cooker in the liquid or should it be placed on the trivet or basket like a pork roast?

I put the lamb along the bottom of the pot. I don’t use a trivet or basket.

I have a 6.5 lb leg of lamb…how long do I cook it?

Thanks,
Twin Mom

I’m not sure that would fit in a 6 quart pressure cooker. Do you have a larger one, like 8 quarts? It might also be difficult to brown the leg since it’s so large. I suggest cutting it in half, in which case the cooking times would remain the same.

This is such a fast recipe and the lamb came out terrific!
