How do I know when the rack of lamb is done?

The rack of lamb is done when the juices run clear. To check, make a small cut into the thickest part of the meat and take a peek. The lamb must cook longer if the juices are still pink or red

If they’re clear, it’s ready to be taken off the heat. Keep in mind that lamb is best when cooked to medium-rare, so err on the side of caution if you’re unsure. When in doubt, pull it off the heat and let it rest for a few minutes to allow the juices to redistribute.

Should I cover the rack of lamb with foil?

We recommend covering the rack of lamb with foil for the first 20 minutes of cooking, then removing the foil for the last 5 minutes to allow the exterior to brown.

This will help ensure that the lamb is perfectly cooked without overcooking the exterior.

Can I add or replace some ingredients?

Absolutely! Feel free to experiment with different seasonings and herbs. You could also try replacing the white wine in the sauce with red wine or using a different type of broth. The possibilities are endless, so have fun with it!

Tips and tricks for a better recipe

Fresh herbs

First of all, you can also sear the lamb in a hot pan on all sides before cooking it in the oven if you want a more crispy exterior.

  • If you don’t have a rack, you can cook the lamb directly on a baking sheet lined with foil or parchment paper.
  • Baste the lamb with the sauce a few times while cooking in the oven to help keep it moist and flavourful.
  • Use fresh herbs like rosemary or thyme to season the lamb before cooking for an even more flavourful dish.
  • You could also add garlic cloves to the pan when searing the lamb for extra flavor.
  • For an extra-special touch, try crumbling some feta cheese over the top of the chops just before serving.
  • If you want to save some time, you can make the sauce ahead of time and just reheat it when you’re ready to serve the lamb.
  • This recipe would also be delicious with a grilled or roasted chicken if you’re not in the mood for lamb.
  • If you have leftovers, they make great sandwiches the next day! Just slice up the lamb chops and put them on some crusty bread with a bit of the sauce.
  • You could also turn this into a healthy salad by serving the lamb over some mixed greens with a light vinaigrette dressing.

And finally, for a more indulgent version, try serving the lamb chops with mashed potatoes and gravy instead of the sauce.

Final Words

This easy rack of lamb recipe is the perfect way to impress your guests at your next dinner party.
