Vietnamese lamb shanks with sweet potatoes
About this recipe
Vietnamese cooking layers fresh herbs (mint, basil, cilantro) into nearly every dish, served alongside grilled meats, broths (pho being the most famous), and the salty-sour-sweet-spicy balance of nuoc cham. Heat is on the table, not built into every dish.
As a lamb dish, Vietnamese lamb shanks with sweet potatoes works the same braising-vs-fast-cooking divide as beef — lean cuts for hot fast cooking, tougher cuts for time-and-temperature stews where the flavour deepens.
The scaler above resizes every ingredient to the number of servings you actually want; Cook Mode walks you through the recipe one step at a time with hands-free timers.

Method
- step 1
- Heat oven to 160C/140C fan/gas 3. Heat 1 tbsp oil in a heavy-bottomed casserole, season the shanks, then brown them 2 at a time on all sides, adding the remaining oil for the second batch. Remove the lamb and add the onions. Fry them quite briskly, about 30 secs, add the ginger, garlic and chopped chilli, then turn the heat down and cook for 1 min. Add 1 tbsp sugar, stir, then add the star anise, lemongrass, stock, purée and seasoning. Bring to the boil.
- step 2
- Cover and cook in the oven for 1½ hrs, then add the sweet potatoes and cook for 1 hr more. The lamb should be completely tender and almost falling off the bones. Stir in the fish sauce, lime juice and 1 tsp sugar to just lift the flavour, then scatter with the mint, basil and the sliced chilli to serve.
Cooking notes
When scaling protein-led dishes, weigh the meat rather than counting pieces, and remember that the pan size limits how much you can sear at once.
For volume-to-weight conversions of any ingredient — flour, sugar, butter, salts — use the ingredient converter. To translate the recipe's oven temperature between °C, °F and gas mark, see the temperature converter.
When you scale this recipe up or down, remember that cooking time does not scale linearly. A doubled cake takes longer, but not twice as long; a doubled soup takes roughly twice as long. The cooking-time guide gives sensible starting estimates by dish geometry.
Scaling notes
Scaling Vietnamese lamb shanks with sweet potatoes
Vietnamese lamb shanks with sweet potatoes is written for around four servings as it stands on this page — scaling it up for a party or down for a meal-for-one is the small math problem most home cooks face every week. Here's how this particular dish responds to scaling, what changes linearly, and what doesn't.
Lamb cooks similarly to beef but is leaner, which means scaling Vietnamese lamb shanks with sweet potatoes up calls for slightly longer rest time after cooking (proportional to thickness, not mass). Braises and stews scale linearly; roasts follow the cube-root rule — doubling a lamb leg adds about a quarter to the cook time, not double.

Beyond the recipe
Substitutions & make-ahead — Vietnamese lamb shanks with sweet potatoes
Two things home cooks ask about most when they're outside the recipe's exact assumptions: what swaps work for which ingredients, and how the dish behaves when you make it ahead. Both depend on what Vietnamese lamb shanks with sweet potatoes is doing structurally — here's the practical version.
Substitution ideas
Brown sugar
Brown sugar = white sugar + molasses. For 1 cup light brown sugar, use 1 cup granulated sugar + 1 tbsp molasses; for dark brown, 2 tbsp molasses. Coconut sugar is a near-1:1 swap with slightly less caramel depth — works for both light and dark.
For weight-based swaps and arbitrary quantities, the ingredient density converter and the cup-to-grams chart cover most pantry staples.
Make-ahead and storage
Lamb behaves like beef for storage — braises and stews like Vietnamese lamb shanks with sweet potatoes (when it's in that family) improve overnight as the spice and acid components marry. Refrigerate in a wide shallow container; reheat gently with a splash of the cooking liquid. The stronger flavour signature lamb carries mellows during storage, which can be a feature (a milder leftover the next day) or a bug (the original character gets muted) depending on what you're after.
