This is a ground lamb burger seasoned with a Rogan Josh spice blend — paprika, cumin, ginger, garam masala, cinnamon, and more — then topped with cucumber raita, caramelized red onions, and mixed greens on a toasted brioche bun. The honest reason to make it: the spice mix does most of the heavy lifting, so even a first-time burger maker ends up with something that tastes genuinely complex. It’s a weeknight-friendly cook that doesn’t require any special equipment.
Why this recipe works
Two things actually matter here. First, the spices go directly into the ground lamb rather than onto the surface. Fat-soluble aromatics like garam masala and cinnamon need heat and fat to bloom, and mixing them into the meat means every bite gets that depth instead of just the crust. Second, the cucumber raita is thick Greek yogurt, not regular yogurt — that higher protein content keeps it from turning watery and sliding off the patty. Those two choices are what separate a burger that tastes put-together from one that tastes like an experiment.
Smart swaps
- Ground lamb: If your store only carries lamb shoulder roast, ask the butcher to grind it, or pulse it yourself in a food processor in short bursts until coarsely ground — don’t over-process or it turns to paste.
- Brioche bun: A potato roll works well and holds up to the raita without going soggy as fast. Standard sesame buns are fine but tend to compress under the moisture.
- Greek yogurt for raita: Full-fat is worth it here. Low-fat versions release more liquid as they sit, which makes the bun wet before you finish assembling.
- Garam masala: Store-bought is completely fine. No need to toast and grind your own for this recipe.
If something goes sideways
- Patty falls apart on the grill: Ground lamb is leaner than beef and needs a cold start. If your patties are crumbling, they were probably too warm before they hit the heat. Refrigerate shaped patties for at least 20 minutes before cooking.
- Burger tastes flat despite all the spices: Salt is the amplifier. Taste your raw mix by cooking a small pinch in a dry pan — if it tastes dull, add a little more kosher salt before shaping.
- Raita is too runny: Grated cucumber releases a lot of water. After grating, squeeze the cucumber firmly in a clean kitchen towel or paper towels before mixing it into the yogurt.
- Patty is cooked through but dry: Ground lamb can dry out fast over high heat. Use medium-high, not screaming hot, and pull the patty at 160°F internal — use an instant-read thermometer if you have one.
- Caramelized onions are burning, not softening: They need low heat and patience, usually 25-30 minutes. If the pan looks dry and the onions are catching, add a small splash of water and turn the heat down.
Make-ahead notes
Shaped raw patties keep in the fridge for up to 24 hours — stack them with parchment between each one and cover tightly. They also freeze well for up to 2 months; freeze on a baking sheet first, then transfer to a zip bag. Cook from frozen over medium heat with a lid on, adding a few extra minutes per side, and confirm 160°F internal before serving. The raita can be made up to 2 days ahead and stored in an airtight container in the fridge — skip the egg in the mix — it makes the patty mushy — and give the raita a quick stir before using since some liquid will separate. Caramelized onions reheat well in a small pan over low heat with a splash of water.
Indian Rogan Josh Lamb Burger
Ingredients
For the Lamb Patty Mixture:
- 1 lb ground lamb preferably 80/20 for juiciness
- 1 tbsp Rogan Josh spice mix or use equal parts paprika, ginger, cumin, cinnamon, garlic powder, and garam masala
- 1 tsp kosher salt adjust to taste
- ½ tsp black pepper freshly cracked
- 1 tbsp chopped cilantro freshly chopped
For the Cucumber Raita:
- ½ cup plain Greek yogurt full-fat preferred
- ½ cup grated cucumber squeezed dry
- 1 clove garlic minced
- 1 tsp lemon juice freshly squeezed
For the Caramelized Onions:
- 1 large red onion sliced thin
- 2 tbsp unsalted butter for caramelizing
For Assembly:
- 4 pieces brioche buns toasted
- 1 cup mixed greens baby arugula or lettuce blend
Instructions
- Prepare the Lamb Patties: In a mixing bowl, combine ground lamb, Rogan Josh spice blend, salt, pepper, and cilantro. Gently mix by hand until just combined—overmixing can make the patties tough. Form into 4 equal-sized patties, about ¾ inch thick. Refrigerate for 15 minutes to help them hold their shape.
- Make the Cucumber Raita: In a small bowl, whisk together Greek yogurt, grated cucumber (well squeezed to remove water), garlic, and lemon juice. Season to taste with salt. Set aside in the fridge to chill.
- Caramelize the Onions: In a skillet over medium heat (around 350°F / 175°C), melt butter and sauté the sliced onions slowly for about 15–20 minutes, stirring occasionally. Cook until deep golden brown and jammy for a sweet counterpoint to the spicy lamb.
- Cook the Patties: Heat a cast iron skillet or grill over medium-high heat (approx. 400°F / 200°C). Sear lamb patties for 4–5 minutes per side until the internal temperature reaches 160°F (71°C) for medium doneness. Rest the patties for 2–3 minutes off heat.
- Toast and Assemble: Lightly toast the brioche buns. Spread a spoonful of cucumber raita on the bottom half. Place the lamb patty on top, add caramelized onions, a small handful of mixed greens, and cover with the top bun. Serve immediately.
Notes
- Add a slice of paneer or spicy pickled onions for extra flair.
- Use beef as a substitute, though lamb is preferred for authenticity.
- To speed up caramelizing onions, add a pinch of baking soda to accelerate browning, but stir frequently to prevent burning.

Frequently asked questions
Can I use beef instead of lamb?
Yes, 80/20 ground beef works and the spice blend still tastes great. The flavor will be milder since beef doesn’t have lamb’s natural richness, but it’s a solid substitute if lamb isn’t available or affordable.
How do I know when the lamb patty is fully cooked?
Use an instant-read thermometer and cook to 160°F (71°C) internal — that’s the safe temperature for all ground meat. Cut-and-peek is unreliable with spiced patties because the dark spices make the interior look done before it is.
My grocery store doesn’t carry Kashmiri chili powder. What do I do?
Use a mix of regular paprika and a small pinch of cayenne. Kashmiri chili is mild and very red, so straight cayenne alone will make it too hot — the paprika-plus-cayenne combo gets you close.
Can I cook these on a stovetop instead of a grill?
Absolutely — a cast iron skillet over medium-high heat works great. You get a better crust indoors than on a gas grill at lower temperatures, and it’s easier to monitor the heat.
How do I stop the bun from getting soggy from the raita?
Spread the raita on the top bun, not the bottom, and assemble right before eating. If you’re making these for a group, keep the components separate and let people build their own.
Can I make the patties smaller for sliders?
Yes — aim for about 2 oz each and reduce cook time accordingly, checking for 160°F internal. Slider-size patties cook fast, so watch them closely; they can go from done to dry in under a minute.
