This one pot chicken and green olive tagine is one of those deeply comforting dishes that manages to feel both exciting and effortless at the same time. Chicken thighs simmer slowly with ras el hanout, preserved lemons, olives and honey until the sauce becomes rich, fragrant and full of flavour.

It’s a wonderfully simple dinner to make because everything cooks together in a single pot. Once the ingredients are assembled and the pot goes into the oven, the dish more or less takes care of itself while the flavours slowly develop.

Why Tagine Flavours Are So Special

Tagines are a traditional Moroccan style of cooking, named after the clay pot in which they’re usually prepared. Even when cooked in an ordinary casserole dish, the flavours remain distinctive and incredibly satisfying.

What makes tagine cooking so appealing is the balance of flavours. Instead of focusing purely on savoury notes, Moroccan cooking often combines sweetness, spice, salt and acidity in the same dish.

In this recipe:

honey adds gentle sweetness
preserved lemons bring brightness and a subtle bitterness
olives provide saltiness
ras el hanout adds warm spice

The result is a dish that feels layered and complex even though it’s made with very straightforward ingredients.

Why Chicken Thighs Work Best in Tagine

For tagines and slow-cooked dishes like this, chicken thighs are far better than chicken breast.

Thigh meat contains a little more fat and connective tissue, which means it stays tender and juicy during longer cooking times. Chicken breast, on the other hand, tends to dry out if simmered for too long.

Skinless thighs are ideal here because the dish cooks in liquid rather than roasting. Skin can sometimes become slightly rubbery in a stew or tagine, so removing it gives a better final texture.

Whether you use bone-in or boneless thighs is really down to personal preference – both work well.

If you enjoy cooking chicken this way, my One Pot Chicken, Bacon and Peas is another comforting one-pan chicken dish that’s packed with flavour.

Ingredients, Substitutions and Variations

This recipe uses a handful of classic tagine ingredients that together create the distinctive flavour of the dish.

Chicken thighs – Skinless chicken thighs work best here. They remain tender during cooking and absorb the flavours of the sauce beautifully.
Olive oil – Used to brown the chicken and start the base of the sauce.
Onions and garlic – These form the aromatic base of the dish and add natural sweetness as they cook.
Ras el hanout – A Moroccan spice blend typically containing spices such as cumin, coriander, cinnamon, paprika and turmeric. It’s warm, fragrant and slightly sweet.
Ground ginger – Ground ginger works best here because it blends smoothly into the sauce. Fresh ginger would be too strong and sharp.
Cinnamon stick – Adds warmth and depth to the sauce.
Preserved lemons – Preserved lemons are one of the defining flavours of many Moroccan dishes. Their slightly fermented, salty-citrus flavour brings brightness and complexity to the sauce.
Honey – Adds a gentle sweetness that balances the acidity of the tomatoes and preserved lemons.
Green olives – Green olives bring saltiness and a slight bitterness that contrasts beautifully with the sweet and spicy elements of the dish.
Chopped tomatoes – These form the base of the sauce and bring everything together.

A Few Helpful Tips for the Best Tagine

Don’t fully cook the chicken at the start – When you first brown the chicken, you only need to colour it on the outside. It will finish cooking later in the sauce, so there’s no need to cook it through at this stage. If you cook it completely during the browning stage, the chicken can become overcooked by the end of the recipe.
Let the flavours develop slowly – The oven cooking stage allows all the spices and ingredients to meld together. Even though the dish doesn’t take long to cook, the slow simmering helps build a richer flavour.
It tastes even better the next day – Like many stews and braised dishes, this tagine actually improves with time. The flavours deepen overnight, making leftovers particularly delicious.

How to Turn This into a Full One-Pot Meal

If you’d like the dish to be a little heartier without serving it with couscous or rice, adding chickpeas works beautifully.

Simply stir two tins of drained chickpeas into the sauce at the same time as the tomatoes. They soak up the flavours of the tagine and add a lovely creamy texture.
