This is a fast stir-fry built around ground lamb, cucumber, garlic, ginger, and chili paste — on the table in 30 minutes. The lamb is rich enough to carry the heat, and the cucumber keeps the whole thing from feeling heavy. It pulls solid protein into a weeknight meal without much effort.
Before you start
The two things that actually matter here are heat and moisture control. A wok or wide pan needs to be genuinely hot before the lamb goes in — medium-high at minimum. If the pan is too cool, the lamb steams instead of browns, and you lose the slightly crispy edges that make the texture work. The second thing: pat the cucumber slices dry with a paper towel before they go in. Cucumber holds a lot of water, and if you skip this step, the liquid releases into the pan and turns the whole dish soupy. Thirty seconds of prep makes a real difference.
Ingredient notes
- Chili paste: Doubanjiang (fermented broad bean and chili paste) is the closest match to a Hunan-style base and worth finding in an Asian grocery. Standard sriracha works in a pinch but tastes noticeably different — less depth, more sweetness.
- Rice vinegar: Don’t swap this for white wine vinegar. Rice vinegar is milder and less sharp; white wine vinegar will overpower the other flavors.
- Ground lamb: Higher-fat ground lamb (around 20% fat) browns better and stays juicy. Very lean lamb can dry out quickly at high heat.
- Cucumber: English cucumber works well here. If you’re using a standard waxed cucumber, peel it and scoop out the seeds before slicing — the seeds add extra moisture you don’t want.
Mistakes to avoid
- Not breaking up the lamb fast enough: Ground lamb clumps if you leave it alone. Stir and break it up constantly in the first two minutes or you end up with uneven chunks — some overcooked, some not. Internal temperature should reach 160°F (71°C) throughout.
- Adding garlic and ginger too early: The recipe adds them after the lamb is browned, which is correct. If you add them to a cold pan at the start, they burn before the meat is cooked and turn bitter.
- Overcrowding the pan: If you’re doubling the recipe, cook the lamb in two batches. A crowded pan drops the temperature and the meat stews rather than fries.
- Skipping the sesame oil step: Sesame oil added mid-cook loses its aroma. Adding it off the heat at the end is what gives it any impact — skip adding it earlier if you’re tempted.
- Over-cooking the cucumber: Two minutes is enough. Beyond that it goes limp and watery. Pull the pan off the heat while the cucumber still has some resistance.
Make-ahead notes
The cooked lamb mixture keeps well in an airtight container in the fridge for up to 3 days. Store it without the cucumber — cucumber added before storage turns soft and waterlogged. When you’re ready to eat, reheat the lamb in a hot pan for 2–3 minutes, then stir in freshly sliced cucumber for the last 2 minutes. The dish also freezes reasonably well without the cucumber; freeze for up to 2 months and thaw overnight in the fridge before reheating. Spring onion garnish is worth skipping on leftovers — not worth the extra dish when you’re reheating a quick meal.

Your questions, answered
Can I use a regular frying pan instead of a wok?
Yes, a wide, heavy frying pan works fine. The key is surface area — use the largest pan you have so the lamb spreads out and browns rather than steams.
How do I know the ground lamb is fully cooked?
Ground lamb needs to reach an internal temperature of 160°F (71°C). Visually, it should be browned with no pink remaining and the juices should run clear — the recipe’s 5-minute cook time is a good guide at medium-high heat, but use a thermometer if you’re unsure.
What can I serve this with to make it a complete meal?
Steamed jasmine rice is the straightforward answer — it soaks up the sauce and adds enough carbohydrate to make the 443 calories per serving genuinely filling. Rice noodles or plain noodles also work if you want something quicker to prepare.
Can I swap the lamb for another ground meat?
Ground pork is the most natural substitute and keeps the cooking time the same (also cook to 160°F/71°C). Ground chicken or turkey will work but cook to 165°F (74°C) and note they are leaner, so add a small splash of water if the pan looks dry.
Is this dish very spicy, and how do I dial it back?
At 1 tablespoon of chili paste it has a noticeable kick but isn’t overwhelming for most people. Start with half a tablespoon if you’re sensitive to heat — you can always stir in a little more at the end once you’ve tasted it.
