Microgreen Lamb Burger with Tzatziki

Quick answer: These lamb burgers come together in about 35 minutes and are worth every second. Season ground lamb with cumin, garlic, and oregano, then top with homemade tzatziki and a handful of peppery radish microgreens — the greens cut through the richness of the meat and keep each bite feeling fresh. It's a bold, satisfying dinner that works just as well on a weeknight as it does at a backyard cookout.

Microgreen Lamb Burger with Tzatziki

A ground lamb patty seasoned with cumin, garlic, and oregano, topped with homemade tzatziki and a handful of radish microgreens — the heat of the greens cuts right through the richness of the meat.

Prep time: 20 minutes | Cook time: 15 minutes | Serves: 4

Lamb burgers have more fat and flavor than beef, which means they can stand up to bold toppings without getting lost. The tzatziki adds a cool, acidic contrast, and the radish microgreens bring a sharp, peppery bite that keeps every mouthful from feeling too heavy. This is a solid weeknight dinner or a backyard cookout centerpiece that doesn't require much fuss.

Ingredients

For the lamb patties:

• 1½ lbs ground lamb (80/20 fat ratio if available)


• 3 cloves garlic, minced


• 1 tsp ground cumin


• 1 tsp dried oregano


• ½ tsp smoked paprika


• ½ tsp kosher salt


• ¼ tsp black pepper


• 1 tbsp olive oil (for the pan or grill grates)

For the tzatziki:

• 1 cup full-fat Greek yogurt


• ½ English cucumber, grated and squeezed dry


• 2 cloves garlic, minced


• 1 tbsp fresh dill, chopped (or 1 tsp dried)


• 1 tbsp fresh lemon juice


• ½ tsp kosher salt


• 1 tbsp olive oil

For assembly:

• 4 brioche or ciabatta buns, toasted


• 1 large handful radish microgreens (about 1 oz) from Wind River Greens


• ½ red onion, thinly sliced


• 4 slices ripe tomato (optional)

Instructions

1. Make the tzatziki first. Grate the cucumber on a box grater, then wrap it in a clean kitchen towel and squeeze out as much liquid as you can. Combine the squeezed cucumber, Greek yogurt, minced garlic, dill, lemon juice, salt, and olive oil in a bowl. Stir well, taste for seasoning, and refrigerate while you prep the burgers. Tzatziki made even 30 minutes ahead tastes noticeably better than tzatziki made to order.

1. Mix the lamb patties. In a large bowl, combine the ground lamb with the garlic, cumin, oregano, smoked paprika, salt, and pepper. Mix with your hands until the spices are evenly distributed — about 30 seconds. Don't overwork the meat or the patties will be dense.

1. Form the patties. Divide the mixture into 4 equal portions and shape each into a patty about ¾ inch thick. Press a shallow indent in the center of each patty with your thumb. This prevents the burgers from puffing up and bowing in the middle as they cook.

1. Cook the patties. Heat a cast iron skillet or grill to medium-high. Brush with olive oil. Cook the patties 4–5 minutes per side for medium (internal temp 160°F). Lamb burgers are best cooked through — unlike beef, they don't benefit from being served rare. Let them rest on a plate for 3 minutes before assembling.

1. Toast the buns. While the patties rest, toast the buns cut-side down in the same pan for about 60 seconds until golden.

1. Assemble. Spread a generous spoonful of tzatziki on both halves of the bun. Place the patty on the bottom bun, add red onion and tomato if using, then pile on a good handful of radish microgreens. Add the top bun and serve immediately.

Tips

• Squeeze the cucumber thoroughly. Watery tzatziki makes soggy buns. The cucumber needs to be as dry as possible before it goes into the yogurt. A second squeeze never hurts.

• Radish microgreens are the right call here. Their sharp, peppery flavor holds its own against the spiced lamb in a way that mild microgreens won't. If radish microgreens aren't available, spicy arugula microgreens give you the same kind of bite. You can learn more about how we grow our radish microgreens in our radish microgreens growing guide.

• Don't skip the thumb indent. It sounds like a small detail, but lamb has enough fat that patties will swell significantly in the center without it. The indent ensures you get a flat, even cook.

• Make the tzatziki the night before. It keeps well in the fridge for up to three days, and the garlic flavor develops more fully overnight. If you're hosting, getting this done ahead of time cuts your day-of work in half.

Serve these with a simple cucumber and tomato salad dressed in red wine vinegar — the same flavors as the tzatziki, played out on the side.

Why Radish Microgreens Work So Well Here

Most burger toppings add bulk or moisture — lettuce, tomato, pickles. Radish microgreens do something different. They add actual flavor contrast, not just texture, and that contrast is what makes this burger feel more intentional than a standard lamb patty stacked with greens.

Radish microgreens carry glucosinolates, the same sulfur compounds that give mature radishes their bite. In microgreen form, that sharpness is concentrated but not harsh — more of a clean, peppery heat that lingers for a second and then clears. That quality is specifically useful here because lamb fat coats the palate. The radish greens cut through that coating and reset your taste buds between bites. The tzatziki does similar work with acidity, but the microgreens handle the job through heat and bitterness rather than sourness. The two toppings work on different registers, which is why both belong on the burger instead of just one.

From a practical standpoint, radish microgreens also hold up better than baby spinach or arugula under warm conditions. They don't wilt immediately when they hit a hot patty. If you're assembling these at a cookout and the burgers sit for a few minutes before people eat, the greens will still have structure when someone picks up their plate.

Daikon radish microgreens are slightly milder than standard radish varieties and work well if you're serving people who are sensitive to spice. China Rose radish microgreens lean a little more pungent and pair especially well with the cumin in the lamb seasoning. Either variety works — just know that the flavor intensity differs between them.

Getting the Most Out of Your Tzatziki

The tzatziki recipe in this post is straightforward, but a few details make a real difference in the final result.

Squeeze the cucumber thoroughly

This step gets mentioned in the instructions, but it's worth expanding on. An English cucumber has a lot of water. If you grate it and stir it straight into the yogurt without squeezing, you'll have a watery sauce within ten minutes. Wrap the grated cucumber in a clean kitchen towel or several layers of cheesecloth and squeeze hard — harder than feels necessary. You'll be surprised how much liquid comes out. The goal is a dry, almost crumbly pile of cucumber shreds before it goes into the bowl.

Salt the yogurt, not just the cucumber

The recipe calls for half a teaspoon of kosher salt total. Add it to the yogurt base rather than sprinkling it over the cucumber after squeezing. Salt dispersed through the full mixture gives you more even seasoning. Taste before refrigerating and adjust — full-fat Greek yogurt brands vary in their base salinity, so what works with one brand might need a small adjustment with another.

Let it sit

Thirty minutes in the refrigerator makes a noticeable difference. The garlic mellows slightly, the dill infuses into the yogurt, and the lemon juice integrates rather than tasting sharp and separate. If you have time to make tzatziki an hour or two ahead, do it. It keeps well in the refrigerator for up to three days, which means any leftovers are useful — spoon them over roasted vegetables, serve alongside grilled chicken, or use as a dip for warm pita.

Full-fat yogurt only

Low-fat Greek yogurt is thinner and more acidic. The sauce won't coat the burger the same way, and the texture turns loose after the cucumber is added. Stick with full-fat. Fage, Stonyfield, and Chobani all make full-fat Greek yogurt that works well here. If you can find a Middle Eastern or Mediterranean market near you, their house-brand full-fat yogurt is often thicker and richer than what you'll find at a standard grocery store.

Equipment Notes

You don't need specialized equipment to make these burgers, but a few items make the process easier and produce a better result.

Cast iron skillet vs. grill

Both work, but they produce slightly different results. A cast iron skillet gives you a hard sear on the exterior of the patty and retains heat evenly, which helps cook the lamb through without drying it out. The trade-off is that lamb renders a significant amount of fat, and cooking four patties in a skillet indoors will produce smoke. Make sure your kitchen ventilation is running, or open a window before you start.

A grill gives you better airflow for the smoke and adds a faint char that complements the cumin and paprika in the seasoning. The downside is that lamb fat dripping onto the flame causes flare-ups. Keep a section of your grill at medium heat rather than high, and be ready to move patties if the fire spikes. Brush the grates with oil right before the patties go on — not during preheating — to reduce sticking.

Instant-read thermometer

The instructions call for an internal temperature of 160°F, which is the USDA guideline for ground lamb. Unlike a beef burger where medium-rare is an option, ground lamb is better served cooked through. The fat content keeps the patty moist at 160°F in a way that lean ground beef isn't. An instant-read thermometer takes the guesswork out of timing — a Thermapen or a basic Lavatools Javelin both work well and cost between $25 and $100 depending on the model.

Box grater

Use the large holes on a standard box grater for the cucumber. Fine grating produces too much liquid too quickly and turns the cucumber into a paste rather than shreds. Large-hole grating gives you pieces with some structure that, once squeezed, add a little texture to the tzatziki rather than disappearing into it.

What to Serve Alongside

Lamb burgers are rich, and the tzatziki and microgreens help balance that on the burger itself. What you serve on the side should follow the same logic — lean toward fresh, acidic, or lightly dressed options rather than anything heavy or creamy.

Fattoush salad

Fattoush is a Lebanese chopped salad made with tomatoes, cucumber, radishes, fresh herbs, and toasted or fried pita. The sumac dressing is sharp and citrusy, which plays well against the lamb without competing with the tzatziki. It also uses ingredients you likely already have on the counter from this recipe — cucumber, tomato, red onion — so there's minimal additional prep.

Roasted chickpeas

Toss canned chickpeas with olive oil, cumin, and smoked paprika — the same spices already in your lamb patties — and roast at 425°F for 25 to 30 minutes until they're crisp. They make a good finger-food side that keeps the Mediterranean flavor profile consistent across the meal.

Lemon herb couscous

Plain couscous takes about five minutes to prepare and absorbs flavor well. Dress it with lemon juice, olive oil, fresh parsley, and a little salt. It's a neutral base that fills out the plate without pulling focus from the burger. Israeli couscous (pearl couscous) has a chewier texture and holds up better if you're serving a crowd and the food sits out for a bit.

Simple cucumber and mint salad

Slice half an English cucumber thin, toss with rice wine vinegar or white wine vinegar, a pinch of sugar, salt, and torn fresh mint. Let it sit for ten minutes before serving. The vinegar gives it a pickled quality without the wait time of actual pickling, and the mint bridges the flavors from the tzatziki to the salad without being redundant.

If you want something simpler, a plate of olives, hummus, and warm pita alongside the burgers turns the meal into a casual spread that works well when you're feeding more people or want to keep cooking to a minimum. The lamb burger becomes the centerpiece rather than the only thing on the table, which takes some pressure off the timing.

Nutrition Notes

Ground lamb at an 80/20 fat ratio is higher in saturated fat than most ground beef options at the same ratio, but it's also higher in zinc, iron, and vitamin B12. A single patty made from 6 ounces of ground lamb contains roughly 380 to 420 calories depending on how much fat renders during cooking, along with approximately 28 grams of protein. The tzatziki adds roughly 60 to 80 calories per two-tablespoon serving, mostly from fat in the full-fat yogurt, but also contributes calcium and a small amount of additional protein. The radish microgreens add negligible calories but contribute vitamin C, folate, and antioxidants from the same glucosinolates responsible for their flavor.

If you're watching saturated fat intake, using a 90/10 ground lamb blend reduces total fat by a meaningful amount, though the patties will be slightly drier. Compensating with a thicker layer of tzatziki helps. The brioche bun adds around 200 calories and can be swapped for a whole grain bun or left out entirely if you prefer to serve the patty over a bed of fattoush or greens.
