Chicken Tagine with Olives and Preserved Lemon
If any dish proves that olives are a backbone of flavour and not just a garnish, it is the Moroccan chicken tagine: chicken braised soft with preserved lemon, green olives and saffron until it falls from the bone and the sauce is deep and glossy.
Every olive-growing culture cooks with its fruit, but few build a whole dish around it the way Morocco does here. This is not olives as a scatter on top — the olives and preserved lemon season the entire pot from within, giving the sauce its salt, its tang and its savoury depth. Get those two things right and the rest is patience. It is also a perfect lesson in restraint, because the commonest ways to ruin it are both about doing too much.
What you need
Bone-in chicken (thighs and legs stay juicy through a long braise); a generous handful of firm green olives — the traditional choice is the Moroccan Picholine, but any good firm green olive works; preserved lemon, skin only, chopped; onion, garlic and fresh ginger; and the warm spice base of saffron, cumin, ground coriander, a little turmeric and black pepper. Fresh coriander and parsley to finish, and good olive oil to start. Nothing here is exotic once you have the preserved lemon, which is simply lemon cured in salt.
The method
Brown the chicken in olive oil and set aside. Soften the onion, garlic and ginger, stir in the spices to wake them up, then return the chicken with a little water, cover, and braise gently for about 45 minutes until the meat is tender and the sauce has reduced and turned rich. Add the olives and preserved lemon only in the last 10 to 15 minutes, scatter with the chopped herbs, and serve with bread or couscous to catch every drop of sauce. Low and slow is the whole technique; there is nothing to rush.
The two rules that make or break it
First, olives and lemon go in late. Boiled for an hour they turn bitter and mushy and surrender all their flavour to the pot; added near the end, they stay bright and perfume the dish. Second, taste before you add any salt. Between the brine-cured olives and the salt-cured lemon, the seasoning is largely done for you, and a heavy hand turns a beautiful tagine inedible. If you can, reach for a green Moroccan-style olive — the dish was built around exactly that fruit.
| Element | Use | The rule |
|---|---|---|
| Chicken | Bone-in thighs & legs | Brown first, braise gently ~45 min |
| Green olives | A firm Moroccan-style green | Add in the last 10–15 min |
| Preserved lemon | Skin only, chopped | In late; it is your main salt |
| Spices | Saffron, cumin, coriander, turmeric | Bloom in the oil before the liquid |
| Salt | Very little, if any | Taste first — olives & lemon salt the pot |
Tips
- Use bone-in chicken; breast alone dries out over a long braise.
- Add olives and preserved lemon late to keep them bright, never bitter.
- Taste before salting — the cure has seasoned the dish already.
- Serve with bread or couscous to soak up the sauce, the best part.
Chicken tagine with olives: common questions
What olives are best for a chicken tagine?
A firm green olive, traditionally the Moroccan Picholine; any good firm green olive works. Avoid soft black olives, which fall apart in the braise.
When do the olives and lemon go in?
In the last 10 to 15 minutes. Cooked longer they turn bitter and mushy and give up all their flavour to the sauce.
Do I need to add salt?
Usually very little or none. The brine-cured olives and salt-cured preserved lemon season the dish, so taste before adding any.
What is preserved lemon?
Lemon cured in salt until soft and intensely fragrant; you use the skin, chopped, for its salty, tangy perfume.
What do I serve with it?
Bread or couscous, to soak up the rich sauce — the reason to make the dish in the first place.
People think a tagine is complicated; it is not. It is a gentle braise with two ingredients that do the heavy lifting — green olives and preserved lemon — and two simple rules. Put them in late so they stay bright, and taste before you salt, because the cure has already done it. Reach for a real green Moroccan-style olive if you can, because that firm, savoury fruit is exactly what the dish was built around. Everything else is just letting the pot take its time.
