Technique Tip for This Recipe
When preparing the leg of lamb for the slow cooker, take the time to massage the olive oil, garlic, rosemary, thyme, salt, and pepper thoroughly into the meat. This ensures that the flavors penetrate deeply, resulting in a more flavorful and aromatic dish. Additionally, searing the lamb in a hot pan for a few minutes on each side before placing it in the slow cooker can add a rich, caramelized crust that enhances the overall taste and texture.

How to Store or Freeze This Dish
- Allow the leg of lamb to cool completely before storing. This helps to prevent condensation, which can make the meat soggy.
- Wrap the lamb tightly in aluminum foil or plastic wrap to maintain its moisture and flavor.
- Place the wrapped lamb in an airtight container or a resealable plastic bag. This will help to keep out any unwanted odors from other foods in the refrigerator.
- Store the lamb in the refrigerator for up to 3-4 days. For longer storage, freezing is recommended.
- To freeze, wrap the lamb in a layer of plastic wrap followed by a layer of aluminum foil. This double wrapping helps to prevent freezer burn.
- Label the package with the date to keep track of its storage time.
- Place the wrapped lamb in a freezer-safe bag or container. This adds an extra layer of protection against freezer burn.
- Store the lamb in the freezer for up to 3 months. For best results, consume within this time frame to enjoy optimal flavor and texture.
- When ready to use, thaw the lamb in the refrigerator overnight. This slow thawing process helps to maintain the meat's quality.
- Reheat the lamb gently in the oven at a low temperature, around 300°F, until warmed through. This prevents the meat from drying out.
- Alternatively, you can reheat the lamb in a sauce or gravy on the stovetop, which adds moisture and enhances the flavor.
How to Reheat Leftovers
Oven Method: Preheat your oven to 325°F (165°C). Place the leftover leg of lamb in a baking dish and cover it with aluminum foil to retain moisture. Heat for about 20-25 minutes, or until the internal temperature reaches 165°F (74°C). This method ensures the lamb remains juicy and tender.
Stovetop Method: Slice the lamb into thin pieces for even reheating. Heat a skillet over medium heat and add a splash of beef broth or olive oil. Place the lamb slices in the skillet and cover with a lid. Heat for about 5-7 minutes, turning occasionally, until warmed through.
Microwave Method: Place the lamb slices on a microwave-safe plate. Add a small amount of beef broth to keep the meat moist. Cover with a microwave-safe lid or another plate. Heat on medium power for 2-3 minutes, checking and stirring halfway through to ensure even heating.
Slow Cooker Method: If you have more time, place the lamb back in the slow cooker. Add a bit of beef broth to prevent drying out. Set the slow cooker to low and heat for 1-2 hours, or until the lamb is warmed through. This method is great for maintaining the original tenderness.
Sous Vide Method: Seal the lamb in a vacuum-sealed bag. Heat a pot of water to 140°F (60°C) using a sous vide machine. Submerge the bag in the water and let it heat for about 45 minutes to an hour. This method ensures the lamb retains its moisture and flavor perfectly.
