Insta Pot Leg Of Lamb: Tender, Juicy, Delicious

how to cook leg of lamb in insta pot

Cooking a leg of lamb in an Instapot is a great way to save time and still enjoy a tender, juicy, and flavorful roast. Pressure cooking a leg of lamb can reduce the cooking time by almost half compared to traditional roasting methods, making it a convenient option for a delicious meal any day of the week. By using the Instapot's pressure cooking function, you can achieve a medium-rare, sliceable roast that is tender and full of flavor. The key to a successful Instapot leg of lamb is to ensure even cooking by cutting the lamb into smaller roasts of roughly the same size, and browning the meat before pressure cooking to enhance its flavor.

Cooking time and temperature

The cooking time and temperature for a leg of lamb in an Instant Pot will depend on the weight of the lamb and how rare you like it. A general rule of thumb is to cook a leg of lamb for about 12 minutes per pound. For example, a 4-pound boneless leg of lamb will take 30 to 35 minutes, depending on how rare you like it. If you prefer your lamb medium-rare, you can cook it for 7 minutes per pound, or for 9 minutes per pound if you prefer it medium. A well-done bone-in roast should be cooked for 12 minutes per pound.

It's important to note that pressure cooking a whole leg of lamb may result in uneven cooking, with the exterior overcooked and the interior undercooked. To avoid this, some people cut their leg of lamb into smaller roasts of roughly equal size before pressure cooking. This ensures that all the meat is cooked evenly and to the desired doneness.

Additionally, the sauté function on the Instant Pot is useful for browning the roast all over before pressure cooking, adding more flavour to the dish. You can also sear the lamb in a separate pan before adding it to the Instant Pot. After pressure cooking, you can place the lamb under a broiler to crisp up the fat, but this step is optional.

When pressure cooking, remember to add some liquid to the pot, such as water, broth, or juices from the lamb, as this creates the steam needed for pressure cooking. For a 4.5-pound leg of lamb roast, pressure cook on high for about 25 minutes for a medium-rare result. For a slightly larger roast, a 4.8-pound leg of lamb can be pressure-cooked for 50 minutes for a tender result.

If you're looking for a slower cooking method, you can try the Slow Cook setting on the Instant Pot. One recipe recommends cooking a Greek-style leg of lamb for 6 hours on the "Slow Cook - High" setting.

Seasoning and preparation

When preparing a leg of lamb in an Instapot, there are a few key steps to follow to ensure juicy and flavourful results. Firstly, it is essential to rinse the lamb with cold water and then pat it dry with a paper towel. This step ensures that the meat is clean and helps to create a dry surface that will brown nicely during cooking.

The next step is seasoning. A generous amount of salt and pepper is a must to enhance the natural flavour of the lamb. For a classic flavour profile, rub the lamb with olive oil, followed by garlic and herbs such as rosemary and thyme. This creates a delicious aroma and adds depth to the dish. You can also experiment with other seasonings like allspice for a Middle Eastern twist.

Before pressure cooking, it is recommended to sear the lamb. This step adds texture and flavour to the dish. Use the sauté function on your Instapot to heat some oil in the pot, and then sear the lamb on all sides for about 4-5 minutes until it is golden brown. This step is crucial as it locks in the juices and creates a delicious crust on the meat.

If you are working with a large leg of lamb, consider cutting it into smaller roasts of roughly equal size. This ensures even cooking throughout, as pressure cooking works best with smaller pieces of meat. A general rule of thumb is that a 4-5 pound boneless leg of lamb will take around 30-50 minutes to cook, depending on your desired doneness.

Browning and crisping

Browning:

Start by rinsing the lamb with cold water and patting it dry with a paper towel. This step removes any excess moisture that could affect the browning process. Seasoning is key to enhancing the flavour of the lamb. Use a generous amount of salt and pepper, and rub it all over the lamb to create a uniform coating. You can also add other seasonings like garlic and herbs for a more complex flavour profile. Once the lamb is seasoned, it's time to sear. Coat the inner pot of the Insta Pot with a tablespoon or two of oil. Turn on the “Saute” function to high heat and let the pot preheat. Place the lamb in the hot oil and sear it on all sides for an even brown crust. The browning process should take around 4 to 5 minutes.

Crisping:

After browning the lamb, you can choose to crisp it for a more textured exterior. Use the “Broiler” function on your Insta Pot to crisp up the fat. Alternatively, you can finish the roast in a separate broiler or oven to achieve the desired crispness. Keep in mind that crisping is an optional step and can be skipped if you are short on time, as the lamb will still be perfectly cooked and tender.

The browning and crisping steps are crucial in developing flavour and texture in your leg of lamb. By following these instructions, you'll be able to achieve a delicious and visually appealing roast. Remember to adjust the cooking time based on your desired doneness and the size of your lamb roast.

Cutting the leg into smaller roasts

When cooking a leg of lamb in an Instant Pot, cutting the leg into smaller roasts can significantly reduce the cooking time and ensure more even cooking. Here's a guide to help you through the process:

Firstly, it is important to note that boneless legs of lamb come in various sizes and shapes. For even cooking, it is ideal to cut the leg into smaller roasts of roughly the same size. Aim for four pieces, each weighing around one pound. This will ensure that each piece cooks evenly and thoroughly.

Before cutting, ensure your boneless leg of lamb is at room temperature. Use a sharp knife to carefully separate the leg into four relatively equal portions. Trim any excess fat or silver skin, as desired. The goal is to create four smaller roasts that will fit comfortably in your Instant Pot.

Once you've cut the lamb into the desired size, it's essential to season the meat adequately. A simple yet effective seasoning mix includes olive oil, garlic, rosemary, thyme, and allspice. Rub the olive oil all over the surface of the meat, followed by the garlic and herbs. Don't be shy with the seasoning—generously coat the lamb with salt and pepper to enhance the natural flavours.

After seasoning, you can proceed with pressure cooking the smaller lamb roasts in your Instant Pot. The general rule of thumb for cooking lamb is about 7-12 minutes per pound, depending on your desired doneness. For a medium-rare result, aim for 7 minutes per pound, while a medium cook would require 9 minutes per pound. Adjust the cooking time accordingly, and remember to let the pressure release naturally for at least a few minutes before removing the lid.

By cutting the leg of lamb into smaller roasts, you can achieve juicy, evenly cooked meat in a fraction of the time it would take to cook a whole leg roast. This technique is perfect for enjoying tender lamb roasts any day of the week without the lengthy cooking process.

Side dishes and serving suggestions

There are numerous side dishes and serving suggestions that go well with a leg of lamb cooked in an Insta Pot. Here are some ideas:

Roasted vegetables are a great option to accompany the lamb. Carrots, celery, and onions can be placed in the bottom of the pressure cooker, with the lamb laid on top, fat side up. You can also serve the lamb with a side of roasted potatoes. If you want to keep things simple, mashed potatoes or cauliflower are excellent choices, and for a low-carb option, you can opt for cauliflower rice. To enhance the flavour of the lamb, you can serve it with an herby sauce, such as gremolata.

If you're looking for some green on the side, a fresh green salad with a herby dressing pairs perfectly with the robust flavour of the lamb. Some other vegetable side dishes that go well are cauliflower cheese, green beans, and baked zucchini casserole with cheese.

For a more filling side dish, you can try quinoa or white/brown rice.
