How to make this breast of lamb recipe.
Once your lamb is seasoned, the oven takes care of the hard part. Slow roasting followed by a quick broil creates tender meat with beautifully browned edges.
- Use your homemade rub or store-bought rub to season the lamb breast.
- Place the seasoned lamb on a foil-lined baking sheet with the fat side facing up and wrap it tightly in foil.
- Let the lamb roast for about 2½ hours, or until it's tender enough to easily pierce with a fork.
- Carefully transfer the lamb to a clean baking sheet, leaving the cooking juices behind.
- Broil for several minutes until the top is browned and lightly crisp, watching closely so it doesn't burn.
- Tent loosely with foil, let the lamb rest for several minutes, then slice between the ribs and serve.
How to serve it.
This roasted lamb breast recipe pairs beautifully with simple sides that let the rich, savory lamb shine.
- Spoon mint chimichurri over the top just before serving.
- Pair it with mashed potatoes or mashed cauliflower to soak up all those flavorful juices.
- Serve alongside roasted vegetables, steamed green beans, or asparagus.
- Add a crisp green salad with a light vinaigrette to balance the richness.
- Finish with chopped fresh parsley and lemon wedges for a bright, fresh touch.
Kori's tips.
- Wrap it tight. A tightly sealed foil packet traps moisture so the lamb stays tender and juicy while it roasts.
- Use a clean baking sheet. Transfer the lamb before broiling to keep the rendered fat from smoking or burning.
- Skip the broiler if you want. Use an air fryer (425-degrees F) or a grill to finish the lamb if it's easier.
- Let it rest. Give the lamb 5 to 10 minutes before slicing so the juices have time to redistribute.
- Make extra rub. Mix a double batch of the smoky lamb rub and store the leftovers in an airtight container for up to 6 months.
FAQs
To store leftovers, let the meat cool completely, then transfer to an airtight container. Store in the refrigerator for up to 4 days. See reheating and freezing instructions below.
You can freeze the leftover breast. Let the meat cool then place in a freezer-safe container or bag. Freeze for up to 3 months.
For the juiciest results, place the lamb in a baking dish with a splash of broth or water, cover with foil, and warm in a 325 degree F oven until heated through. You can also microwave individual portions, but the oven helps keep the meat more tender.
Lamb breast actually comes from the underbelly of the animal. It is one of the fattiest cuts of the lamb and can also be tough - but it is also one of the most flavorful cuts.
Because it can be tough and fatty, it is best to cook the meat for longer periods of time so the fats are rendered and released and the meat is tender.
The breast of lamb has riblets (also called spareribs) and comes from the underbelly of the animal, whereas lamb ribs come from the side of the animal.

Lamb Rub
- 1 tablespoon dried rosemary
- 1 tablespoon dried oregano
- 1 tablespoon marjoram

Instructions
Prep
- Mix the lamb rub ingredients together in a small bowl. Transfer any unused rub to an airtight container for later use.
- Tear off sheets of aluminum foil that extend past the lamb breast about 4 to 6 inches. Hint: if your foil is thin use two sheets to prevent spills and leakage.
- Spray one side of the foil with nonstick spray.
- Preheat the oven to 300 degrees Fahrenheit.
Rub
- Lay the meat on the foil and generously sprinkle with lamb rub on all sides.
- Turn the fat side up and wrap the foil tightly around the lamb and place on a baking sheet - seam side up. Tip: If you have 2 breasts, wrap them separately.
Roast
- Roast the lamb on the middle rack of your oven for about 2½ hours or until very tender.
Broil
- Turn the oven to broil.
- Remove the breast of lamb from the fats and juices and transfer to a separate baking sheet.
- Place under the broiler and let the breast get a nice brown color and a crispier top - watch it carefully as it can burn easily.
- Remove from the oven, tent with foil until ready to serve.
Serve
- Adjust seasoning if needed. Slice between each rib and serve.

Kori, your lamb rub is great! I use it as my “all purpose seasoning” whenever I need a spoonful. I always have fresh parsley, mint and lemon peel on hand so I add those when mixing the rub. This is the only recipe I use for lamb breast — I’d like to share that I put half the rub on and cook it in a pressure cooker for 30-40 minutes with a couple cups of water. Then I put the rest of the rub on and bake or broil the ribs until crisp (when cooking for myself I do this part one section at a time and refrigerate or freeze the others — dinner in an instant!). The resulting broth (and any leftover meat) go into the freezer to make Scotch broth (with barley) or Welsh cawl with lots of root vegetables. Just top off with more water and beef bouillon or save a couple of containers from this great recipe. Thanks!

Eileen, this absolutely made my day! 🧡 I love your detailed process—it sounds incredible, and that broth idea is genius. Adding fresh parsley, mint, and lemon peel gives it such a bright touch too. I’m so glad this rub has become your go-to for lamb (and beyond)! Thank you for sharing your tips—they’re sure to inspire other home cooks!

Hello, yes it's all in the recipe card. I mention using 1 recipe of my lamb rub or use 1/2 cup of your favorite rub. That's for 2 (2-pound) lamb breasts, so if you are making less adjust accordingly. Hope you enjoy! 🙂
