Helpful Tricks for Roast Leg of Lamb
-
Marinate Well: Allow the lamb to marinate for at least 8 hours, preferably overnight. This infuses robust flavors from the orange juice marinade and ensures tasty, tender meat.
-
Room Temperature: Always let your lamb come to room temperature for about 30 minutes before cooking. This helps the meat cook evenly throughout and prevents a cold center.

Season Generously: Don’t hold back on the salt and freshly ground black pepper. A good seasoning at the beginning sets the stage for a delicious roast leg of lamb that pops with flavor.
-
Rest After Cooking: Let the lamb rest for 15-20 minutes after cooking to keep it juicy. This allows the flavors to settle, ensuring each slice is perfectly moist.
-
Use a Meat Thermometer: Check the internal temperature of the lamb to achieve your preferred doneness—medium-rare is around 135°F. This prevents overcooking and dry meat.
How to Store and Freeze Roast Leg of Lamb

Roast Leg of Lamb Recipe FAQs
What type of orange juice should I use for the marinade?
I recommend using fresh-squeezed orange juice for the best flavor, as it provides vibrant sweetness and acidity that enhances the lamb. If fresh isn’t available, a high-quality bottled orange juice without added sugars can work in a pinch.
How long can I store leftover roast leg of lamb?
You can store leftover roast leg of lamb in an airtight container in the fridge for up to 3 days. Make sure to allow it to cool completely before sealing to preserve moisture and flavor.
Can I freeze roast leg of lamb? How should I do it?
Absolutely! To freeze your roast leg of lamb, first allow it to cool completely. Then, wrap it tightly in plastic wrap to minimize air exposure, followed by a layer of aluminum foil for further protection. This method will keep the lamb tasty for up to 3 months. When you’re ready to enjoy it again, thaw it overnight in the fridge for the best results.
Is there a way to ensure the lamb doesn’t dry out during cooking?
Yes! To prevent your lamb from drying out, avoid overcooking it. Use a meat thermometer to check for doneness—medium-rare should reach an internal temperature of about 135°F. Additionally, allow the lamb to rest for 15-20 minutes post-cooking, which helps the juices redistribute, keeping every slice juicy and tender.
Can dogs eat roast lamb? Is it safe for pets?
While plain cooked lamb can be a tasty treat for dogs, it’s essential to ensure there are no added seasonings, particularly garlic or salt, which can be harmful. Always consult your veterinarian before introducing any new foods to your pet’s diet.
What if I can’t find fresh herbs for the marinade?
No worries! If you can’t find fresh thyme or rosemary, dried herbs can be a great substitute. Use about one-third of the amount—1 teaspoon of dried thyme and 1 tablespoon of dried rosemary should work nicely. Just remember to let the herbs bloom in the marinade a bit longer for maximum flavor.
