These are spiced lamb patties — cumin, coriander, smoked paprika, grated onion — served on a toasted brioche bun with a quick mint yogurt sauce. The honest reason to make them: ground lamb costs about the same as good ground beef, takes the same time to grill, and the flavor payoff is noticeably different from anything else you’d put on a cookout spread.
The technique that matters
The two things that actually make or break this burger are moisture control in the patty and getting the grill hot before the meat goes on. Grated onion is doing real work in the mix — it keeps the patties juicy without added fat — but grate it on the fine side and then squeeze out the excess liquid in a paper towel before combining. Too much onion juice and the patties won’t hold together on the grill, especially when you’re cooking a big batch and flipping fast. On heat: lamb fat renders quickly and flares up. Get your grill to high, then keep a cooler zone ready. Sear the patties over direct heat for the crust, then slide them to indirect if they need more time to reach 160°F internal. A thermometer is worth pulling out — lamb looks done before it is.
Ingredient notes
- Ground lamb: Look for 80/20 or close to it. Leaner than that and the patties dry out. Most grocery stores carry it near the ground beef; a butcher counter will often grind it fresh if you call ahead — worth it for a larger cookout order.
- Greek yogurt for the sauce: Full-fat holds up better than low-fat, which can go watery once the lemon juice and mint are mixed in. If you’re making the sauce for a crowd and holding it in a cooler, full-fat is especially important.
- Fresh mint: Dried mint won’t work here — the sauce needs the brightness of fresh leaves. If you can’t find it, fresh flat-leaf parsley plus a small amount of fresh dill gets you closer than dried mint does.
- Brioche buns: Skip the egg in the mix — it makes the patty mushy. And on the bun side, brioche can go soggy fast under the yogurt sauce. Toast them cut-side down on the grill for 60–90 seconds until there’s actual color on them, not just warmth.
If something goes sideways
- Patties falling apart on the grill: The mix was probably too wet. Chill the formed patties uncovered in the fridge for 20–30 minutes before grilling — this firms them up significantly. Works especially well when you’ve made a big batch ahead of time.
- Mint yogurt sauce tastes flat: It needs more lemon juice, not more mint. Add it in small amounts and taste as you go. A small pinch of salt also wakes it up if it was made more than an hour ahead.
- Patties puffing up in the middle during cooking: Press a shallow thumb indent into the center of each patty before it goes on the grill. This is easy to forget when you’re forming two dozen at once — set a reminder or do it as a second pass after all patties are formed.
- Lamb flavor tastes too strong: The spice blend is calibrated to balance lamb’s natural richness, so this usually means the lamb sat too long before cooking. Use it within a day of purchase, or freeze immediately and thaw in the fridge the night before your cookout.
- Buns getting soggy before guests eat: Spread the mint yogurt sauce on the top bun only, not the bottom. The bottom bun sits against the hot patty and absorbs moisture faster — keep it dry or add a leaf of butter lettuce as a barrier.
Spiced Lamb Burger with Mint Yogurt Sauce
Ingredients
For the Lamb Patties:
- 1 pound ground lamb preferably 80/20 fat ratio for juiciness
- ½ cup yellow onion finely grated
- 2 cloves garlic minced
- 1 teaspoon ground cumin
- ½ teaspoon ground coriander
- ½ teaspoon paprika smoked if available
- 1 tablespoon fresh parsley finely chopped
- ½ teaspoon kosher salt
- ¼ teaspoon freshly ground black pepper
For the Mint Yogurt Sauce:
- ½ cup Greek yogurt plain, full-fat
- 2 tablespoons fresh mint finely chopped
- 1 tablespoon lemon juice freshly squeezed
- ¼ teaspoon kosher salt to taste
For Assembly:
- 4 pieces brioche burger buns toasted
- 4 leaves butter lettuce or other tender greens
- 1 large tomato ripe, thinly sliced
- ¼ large red onion thinly sliced
Instructions
- In a large bowl, gently mix together the ground lamb, grated onion, garlic, cumin, coriander, smoked paprika, chopped parsley, salt, and pepper. Do not overmix to maintain tenderness.
- Form the mixture into 4 equal patties, about 3/4 inch thick. Press a slight indent in the center of each patty with your thumb to prevent puffing during cooking.
- For the yogurt sauce, combine Greek yogurt, chopped mint, freshly squeezed lemon juice, and salt in a small bowl. Mix well and refrigerate until ready to use. This can be done up to 4 hours ahead.
- Heat a grill or cast-iron skillet over medium-high heat (375°F / 190°C). Brush patties lightly with oil and cook for 6–8 minutes per side, or until the internal temperature reaches 160°F (71°C) for medium-well. Let rest for 5 minutes.
- Toast brioche buns lightly on the grill or in a skillet until golden brown.
- To assemble, spread mint yogurt sauce on the bottom bun, followed by lettuce, the lamb patty, tomatoes, red onion, and a final dollop of sauce. Cap with the top bun and serve immediately.
Notes
- For a spicier flavor, add a pinch of chili flakes to the lamb mixture.
- You can substitute lamb with beef or a plant-based ground alternative if desired.
- Freeze formed patties between parchment for up to 2 months for easy future use.

Your questions, answered
Can I form the patties the night before a cookout?
Yes, and it actually helps. Form the patties, layer them between sheets of parchment, cover tightly, and refrigerate overnight. Cold patties hold their shape better on a hot grill, which matters when you’re cooking a lot of them at once.
Can I use a mix of ground lamb and ground beef?
A 50/50 blend works fine and produces a milder flavor if you’re cooking for people who are new to lamb. Keep the same spice quantities — the blend still needs the full amount to come through. Cook to 160°F regardless of the ratio.
How far ahead can I make the mint yogurt sauce?
Up to 24 hours ahead, stored covered in the fridge. After that the mint starts to discolor and the texture loosens. If you’re prepping for a party, make it the morning of and give it a quick stir before serving.
Can these be cooked on a stovetop instead of a grill?
A cast-iron skillet over medium-high heat works well. Cook in batches — crowding the pan drops the temperature and the patties steam instead of sear. For a large cookout batch, a skillet is slower than a grill but produces a good crust.
