A juicy grilled lamb burger on a toasted bun with mint mayo, salad leaves, and red onion

A lamb burger is a beef burger's richer, more aromatic cousin, and Gordon Ramsay's leans Mediterranean: ground lamb seasoned with mint, garlic, and coriander, grilled and stacked with a cool mint mayonnaise. Lamb is fattier and more flavorful than beef, which makes for a juicy patty, but it also means a couple of technique points matter if you want it tender rather than dense.

The recipe card below has the full method. This guide covers the two things that make or break the patty, the safe temperature for ground lamb, and how to spin the seasoning toward whichever cuisine you fancy.

Keep the Patty Tender, Not Springy

Two mistakes turn a juicy burger into a bouncy, sausage-textured one, and both are about how you handle the grind. The first is overworking the meat: the more you knead ground meat, the more its proteins link up and the springier and denser it cooks. Mix just until the seasonings are combined, then stop. The second is salting the meat too early. Salt dissolves the meat's proteins so they bind into a tight, springy paste, which is great for a sausage and wrong for a burger, so mix everything else in, form the patties gently, and salt the outside just before they hit the grill.

Two more small moves help. Press a shallow dimple into the center of each patty with your thumb; burgers puff up and dome as the proteins contract, and the dimple keeps them flat. And chill the patties for at least 30 minutes so the fat firms up and they hold together on the grill instead of falling apart.

The Safe Temperature for Ground Lamb

Cook lamb burgers to an internal temperature of 160°F. That is higher than the 145°F you would use for a whole cut of lamb, and the reason is the grinding. On a whole roast or chop, any bacteria live on the surface and the sear kills them; grinding mixes that surface all the way through the meat, so a burger has to reach a safe temperature throughout. The USDA safe minimum for all ground meats is 160°F, the same rule that applies to a beef burger.

Get a hard sear on high heat for the crust (that browning is the Maillard reaction and where a lot of the flavor lives), then check the center with a thermometer. Rest the burgers 5 minutes before serving so the juices settle back into the meat rather than running out at first bite.

Spin the Seasoning

Lamb takes boldly to spice, so the mint-and-coriander base is just a starting point. This is a close cousin of the spiced-lamb kofta traditions across the Mediterranean and Middle East, and you can lean any of those ways: a Moroccan blend of cumin, coriander, and a little cinnamon; an Indian mix of garam masala and a pinch of turmeric; a Turkish baharat with dried mint and sumac; or a Greek turn with oregano. Adjust the salt if your spice blend already contains some.

What to Serve With It

Serve the lamb burger with the mint mayo, red onion, and crisp leaves on a toasted bun, with fries or a sharp salad alongside. If you like this, try Ramsay's meatballs for another ground-meat technique, or go big with a beef Wellington. Browse the full recipes collection for more. Lamb is a rich, iron-heavy red meat, so a bright, acidic side balances it well.

Calories 480 kcal

Ingredients
  

  • 1 lb ground lamb
  • 1 red onion, grated
  • 3 cloves garlic, minced
  • 2 Tbsp fresh mint, chopped
  • 1 Tbsp ground coriander
  • 1 Tbsp Dijon mustard
  • Salt and black pepper (season the outside just before cooking)
  • 4 burger buns, toasted
  • 1/2 cup mayonnaise
  • 2 Tbsp fresh mint, finely chopped (for the mayo)
  • Red onion slices and salad leaves, to serve

Instructions
 

  • Gently mix the ground lamb with the grated onion, garlic, chopped mint, coriander, and Dijon, just until combined. Do not overwork it.
  • Form into 4 equal patties and press a shallow dimple into the center of each. Chill at least 30 minutes.
  • Stir the mayonnaise with the finely chopped mint and set aside.
  • Heat the grill to high. Season the patties with salt and pepper just before grilling. Grill about 4 to 5 minutes per side, until the internal temperature reaches 160°F.
  • Rest the burgers 5 minutes. Toast the buns, spread with mint mayo, and assemble with the patties, red onion, and salad leaves.

Notes

Cook ground lamb to 160°F for safety, not 145°F. Season the outside of the patties rather than mixing salt into the meat, and do not overwork the grind, or the burgers turn springy and dense. The dimple keeps them flat.

Lamb Burger FAQs

The questions that come up most: what temperature to cook a lamb burger to, why patties turn out dense, how to season them, and how to keep them juicy.

What temperature should a lamb burger be cooked to?

To an internal temperature of 160°F. Ground lamb needs 160°F, higher than the 145°F for a whole cut, because grinding mixes surface bacteria throughout the meat. Use a thermometer and rest the burger before serving.

Why did my lamb burgers turn out dense or springy?

Usually the meat was overworked or salted too early. Kneading ground meat and mixing salt in dissolves the proteins into a tight, bouncy paste. Mix gently, form the patties, and salt the outside just before cooking.

Why put a dimple in the center of a burger patty?

Patties dome and puff up as the proteins contract during cooking. A shallow thumbprint in the center compensates, so the burger cooks flat and even instead of bulging in the middle.

How do you keep lamb burgers juicy?

Do not overwork the meat, do not press the patties on the grill (that squeezes out the juices), cook only to 160°F, and rest them 5 minutes so the juices settle back in.

What spices go well in a lamb burger?

Mint, coriander, garlic, and cumin are classic. Lamb also takes Moroccan (cumin, coriander, cinnamon), Indian (garam masala), Turkish (baharat, sumac), and Greek (oregano) blends beautifully.

Do you have to chill lamb burger patties before cooking?

It helps a lot. Chilling for at least 30 minutes firms the fat so the patties hold together on the grill and keep their shape instead of falling apart.
