How to make slow cooker leg of lamb recipe?

Begin: To begin, pour the olive oil into a large skillet on high heat to sear the leg on all sides. This should take about four or five minutes per side.
Slow cooking: Then, add the carrots and potatoes to the slow cooker and season with half of the salt and pepper. Put the meat on top and season with the remaining salt and pepper to start slow cooking.
Season: Next, season the lamb with fresh herbs and garlic before adding the wine and broth to the pot. Pour it on the sides so you do not wash the seasonings off. Add bay leaves.
Cook: After, cover and cook on low for six to eight hours.
Garnish: Last, toss out the bay leaves and garnish with fresh lemon zest and parsley.
Serve: Finally, serve the meat on a serving platter with a small bowl of tzatziki sauce on the side.

Frequently asked questions

Can I cook raw lamb in a crock pot?

There is nothing wrong with cooking raw meat of any kind in a crock pot or slow cooker.

However, if the meat is frozen, you should not try cooking it this way. It takes too long to thaw out to be properly cooked.

Should I brown my lamb before slow cooking?

As in this recipe, searing the meat is best before cooking because it keeps the juices in.

Since this meat has less fat, it needs to keep all of the juices it has to stay moist. Otherwise, it will be dried out or overcooked.

What cut of lamb is best?

A boneless lamb leg is indeed the best cut, especially for slow cooking. However, any kind of lamb meat you happen to find at the grocery store would be delicious.

The lamb shoulder is better cooked in the oven as it has the lamb joint, which takes longer to cook.

How to store leftovers:

Store: After the meat cools to room temperature, you can put it in an airtight container and store in the fridge for three days.
Freeze: If you cannot finish it in three days, wrap it in plastic wrap and aluminum foil, put it in a freezer bag, and freeze for up to 90 days.
Thaw: Thaw in your refrigerator overnight before serving.
Reheat: Reheat in the microwave for one minute or in the oven for about five minutes.

Cooking tips:

Whichever cooking process you use, make sure the meat is at 145 degrees F.
Lamb should still be pink on the inside for best results.
Make a delicious gravy with the drippings in the cooker by mixing in flour and water and cook over medium heat until it boils.
If you want the roast potatoes to be crispy, put them in the broiler for five minutes before serving.
The upper side of the leg has more meat so cook it with that side down.
This is perfect for a high protein diet because it has 56 grams of protein per serving.
