This is a grilled lamb burger seasoned with red onion, garlic, and oregano, served on a toasted bun with a quick cucumber-dill tzatziki. Lamb has more fat than lean beef, which means the patties stay juicy even if you pull them a minute late — a real advantage when you’re managing a hot grill with other things going on. The tzatziki takes about five minutes to mix and doubles as a sauce you’ll want on other things all week.
Before you start
The two things that actually affect the result here are moisture control in the tzatziki and not overworking the lamb. For the tzatziki, grating the cucumber is just the first step — you need to squeeze it hard in a clean kitchen towel or paper towels until almost no liquid comes out. Skip that step and the sauce turns watery within minutes of hitting the bun. For the patties, mix the lamb, onion, garlic, and oregano until just combined. Ground lamb is already fatty and binds easily; the more you work it, the tighter and denser the texture gets. Mix, form, done.
Ingredient notes
- Ground lamb: Look for 80/20 or similar fat content. Leaner lamb (sometimes labeled “extra lean”) will produce a drier patty on a hot grill.
- Greek yogurt: Use full-fat. Low-fat versions release more liquid as they sit, which works against the tzatziki texture.
- Fresh dill: Dried dill works in a pinch — use about one teaspoon in place of one tablespoon fresh — but the flavor is noticeably flatter.
- Burger buns: A slightly sturdier bun (brioche or potato roll) holds up better under the tzatziki than a standard soft white bun, which can go soggy fast.
Mistakes to avoid
- Making patties too thick: Thick patties take longer to cook through, and lamb dries out on the outside before the center is done. Aim for about three-quarters of an inch thick, and press a small indent in the center of each patty so they don’t dome up on the grill.
- Pulling patties too early: Ground lamb should reach 160°F (71°C) internal temperature — use an instant-read thermometer rather than guessing by color, since lamb can look done on the outside while still being undercooked inside.
- Adding tzatziki to hot patties immediately: If you spoon cold tzatziki straight onto a just-grilled patty and then let the assembled burgers sit, the sauce thins out from the heat. Assemble and serve right away, or keep the sauce on the side until people are ready to eat — especially useful when feeding a group.
- Skipping the bun toast: A toasted bun is a barrier against the tzatziki soaking through. Even thirty seconds on the grill makes a difference.
- Under-seasoning the patty mix: Lamb has a strong flavor that can mask salt. Season the mix, then pinch off a small piece and cook it in a pan to taste before forming all four patties — skip the egg in the mix, it makes the patty mushy and isn’t needed here anyway.
Storage and reheating
Cooked lamb patties keep in the fridge for up to three days in an airtight container. Reheat them in a covered skillet over medium-low heat with a splash of water to create a little steam — this takes about three to four minutes and keeps them from drying out. The microwave works but tends to toughen the texture. Tzatziki stores separately in the fridge for up to three days; give it a stir before using since some liquid will settle at the bottom. Raw formed patties can be frozen for up to two months — stack them with parchment between each one and thaw overnight in the fridge before grilling.

FAQ
Can I make the patties ahead of time for a cookout?
Yes — form the patties up to 24 hours ahead, cover them tightly, and refrigerate. Cold patties actually hold together better on the grill than ones formed right before cooking, which is a genuine advantage when you’re prepping for a crowd.
Can I cook these on a stovetop instead of a grill?
A cast iron or heavy skillet over medium-high heat works well. Cook four to five minutes per side and check that the internal temperature hits 160°F (71°C) — you’ll get less char but still good browning.
How do I keep the tzatziki from getting watery if I make it in advance?
Make it up to a day ahead and store it covered in the fridge. The key is squeezing every bit of moisture out of the cucumber before mixing — if you do that properly, the sauce stays thick overnight.
Can I substitute ground beef if I can’t find ground lamb?
Ground beef works, though the flavor is milder and less distinctive. An 80/20 beef blend keeps the patties juicy; the oregano and garlic seasoning still tastes good, it just reads more like a Greek-spiced beef burger.
How many patties can I realistically grill at once if I’m doubling or tripling the recipe?
A standard grill grate fits six to eight patties comfortably without crowding. Crowding traps steam and slows the crust from forming, so work in batches and keep finished patties in a low oven (around 200°F) on a rack while the next batch cooks.
