This is a grilled lamb burger seasoned with cumin and smoked paprika, topped with chimichurri, arugula, avocado, and tomato. Ground lamb has a richer, slightly gamier flavor than beef, which means it needs almost no help — the short ingredient list is a feature, not a shortcut. It comes together in 40 minutes, and the patties hold up well through the week.
Smart swaps
- Ground lamb: If your store only carries lamb shoulder mince, that works well — it has enough fat to stay juicy. Avoid extra-lean lamb; it dries out fast on a grill pan.
- Provolone: Regular provolone melts cleanly here. Aged provolone is sharper and can overpower the lamb — go with the mild version.
- Chimichurri: Store-bought is fine for a weeknight. If you make your own, a batch keeps in the fridge for up to a week, so it doubles as a sauce for anything else you’re cooking.
- Brioche vs. sourdough: Brioche is softer and compresses easily under a juicy patty. Sourdough holds its structure better, especially if you’re packing these for lunch — skip the brioche if the burger is traveling anywhere.
Why this recipe works
Two things matter most here. First, mixing gently and stopping early — overworked ground lamb gets dense and bouncy, not tender. Stir just until the spices disappear into the meat. Second, the grill pan needs to be properly hot before the patties go in. A surface temperature around 400°F gives you a real sear that locks in the fat. If the pan is only warm, the patties steam instead of crust, and you lose the texture that makes this burger worth making. Skip pressing down on the patties while they cook — that pushes the fat out and leaves you with a dry burger.
If something goes sideways
- Patties falling apart in the pan: Ground lamb with too little fat content won’t bind well. Make sure you’re using regular (not lean) ground lamb. Also check that your patties are cold going into the pan — if they warmed up too much during shaping, chill them for 10 minutes before cooking.
- Burger tastes livery or too gamey: This usually means the lamb wasn’t fresh. Check the sell-by date and smell before mixing. A small squeeze of lemon juice into the chimichurri can balance it at the table without masking the lamb flavor entirely.
- Cheese won’t melt in time: Provolone needs a lid to melt properly on a grill pan. Cover the pan loosely with a piece of foil for the last minute — it traps enough heat to melt the slice without overcooking the patty.
- Avocado turning brown before serving: If you’re prepping ahead, keep avocado slices in a small container with a squeeze of lime juice and press plastic wrap directly against the surface. Slice fresh if you can — it takes 30 seconds.
- Patties cooked through but still pink inside: Ground lamb can stay pink even at a safe temperature. Use an instant-read thermometer and pull at 160°F (71°C) for food safety — color alone isn’t a reliable guide with lamb.

Ingredients
Lamb Patty
- 1 pound ground lamb Fresh and preferably grass-fed for richer flavor
- 1 teaspoon ground cumin Adds a warm, earthy note
- 0.5 teaspoon smoked paprika For a subtle smoky flavor
- 0.5 teaspoon sea salt Adjust to taste
- 0.25 teaspoon ground black pepper Freshly ground
- 4 slices Provolone cheese Optional for a creamy addition
Burger Assembly
- 4 pieces burger buns Prefer brioche or sourdough for added texture
- 1 cup Arugula Fresh and peppery
- 0.5 cup tomato slices Heirloom tomatoes preferred
- 0.5 cup avocado slices Fresh, ripe avocados
- 4 tablespoons chimichurri sauce Store-bought or homemade for a zesty kick
Instructions
- Prepare the Lamb Patties: In a large bowl, combine the ground lamb, cumin, smoked paprika, sea salt, and black pepper. Mix gently until just combined. Divide the mixture into four equal portions and shape each into a patty approximately 1.5 cm thick.
- Heat a non-stick grill pan over medium-high heat (around 200°C or 400°F). When hot, add the patties and cook for about 4 minutes on each side for medium-rare, adjusting cook time for desired doneness. If using, place a slice of Provolone cheese over each patty during the last minute of cooking to allow it to melt.
- Assemble the Burger: Toast the burger buns lightly on a separate pan. Spread a tablespoon of chimichurri sauce on each bun base. Place a generous handful of arugula, then the spiced lamb patty on top. Add slices of tomato and avocado. Top with the other half of the bun.

FAQ
Can I make the lamb patties ahead of time?
Yes — shaped, uncooked patties keep in the fridge for up to 2 days, or in the freezer for up to 3 months. Stack them with a small square of parchment between each one so they don’t stick together.
What internal temperature should the lamb patties reach?
Cook ground lamb to 160°F (71°C) internal temperature. Unlike a whole lamb chop, ground meat has been mixed throughout, so you can’t rely on a pink center being safe — use a thermometer.
Can I cook these on an outdoor grill instead of a grill pan?
Absolutely, and the result is slightly better — you get more char and real smoke. Keep the grates clean and well-oiled before the patties go on, since ground lamb sticks more readily than beef.
What can I do with leftover cooked patties?
Cooked patties reheat well in a covered skillet over low heat with a splash of water — about 3 minutes per side. They also crumble well into a grain bowl or wrap with the leftover chimichurri, which is why making a full batch of four at once makes sense even for one or two people.
I can’t find ground lamb — can I grind my own?
Yes, lamb shoulder is the best cut for this. Cut it into chunks, freeze for 20 minutes until firm, then pulse in a food processor until coarsely ground. Don’t over-process or the texture gets pasty.
