I’ll be honest, rack of lamb always sounded like something you’d only order at a restaurant.
It felt too fancy, too expensive, and definitely not something I’d try at home. But once I made it the first time, I realized it’s actually pretty simple when you break it down.
This roasted rack of lamb is like you ordered it in a five-star restaurant. A quick marinade with garlic, rosemary, and thyme adds flavor, and then it’s just a matter of roasting it the right way.
You end up with a crisp, golden outside and tender, juicy meat inside. It looks like something you spent hours on, but most of that time is just letting it sit and soak up flavor.
Ingredients You Will Need
- 1 rack of lamb (about 6–8 ribs)
- 2 cloves garlic, crushed
- 2 tablespoons olive oil
- 1 tablespoon fresh thyme, chopped
- 1 tablespoon fresh rosemary, chopped
- 1/2 teaspoon salt
- 1/3 teaspoon black pepper
How to Make
In a small bowl, mix together the olive oil, chopped thyme, rosemary, and crushed garlic.
Place the rack of lamb on a plate or in a shallow dish and rub the mixture all over, making sure it’s evenly coated on all sides. Transfer it to a zip-top bag, seal, and refrigerate for 5–6 hours or overnight to let the flavors soak in.
About an hour before cooking, take the lamb out of the fridge so it can come to room temperature.
Preheat your oven to 380°F. Place the lamb in a roasting pan with the fat side facing up. If the rib bones are exposed, wrap them loosely in foil to keep them from browning too much.
Roast at 380°F for 12–13 minutes to get a nice crust, then reduce the temperature to 300°F and continue roasting for another 15 minutes, or until the internal temperature reaches about 125°F for rare or 135°F for medium-rare.
Remove the lamb from the oven, loosely cover with foil, and let it rest for 10–15 minutes before slicing between the ribs and serving.
FAQ
Do I really need to marinate the lamb?
It’s not required, but it makes a big difference in flavor. Even a few hours helps, and overnight is even better.
Why should I let the lamb come to room temperature before cooking?
This helps it cook more evenly. If it goes straight from the fridge to the oven, the outside can cook too fast while the inside stays underdone.
How do I know when the lamb is done?
The easiest way is to use a meat thermometer. Aim for about 125°F for rare and 135°F for medium-rare. Insert it into the thickest part of the meat.
Do I need to wrap the bones in foil?
It’s a good idea if the bones are exposed. It keeps them from burning and gives a cleaner look when serving.
Why is resting important?
Resting lets the juices settle back into the meat. If you slice it right away, those juices run out and the lamb won’t be as tender.
How should I slice a rack of lamb?
Use a sharp knife and cut between the ribs to get clean, even pieces.
How long do leftovers last?
Leftover lamb can be stored in the fridge for up to 3 days. It’s great sliced cold or gently reheated.
