How to Use Coriander Seeds in Cooking

Coriander seeds are a highly versatile spice used in many cuisines around the world. Their warm, citrusy aroma adds brightness and balance to savoury dishes and spice blends. The spice can be used either whole or ground. Ground coriander is a key ingredient in many traditional spice blends, including garam masala, baharat and harissa.

Whole or crushed coriander seeds are often used to flavour curries, pickles, chutneys and slow-cooked dishes, where their aroma develops gradually during cooking. Understanding how coriander behaves when cooked will help you decide whether to toast it, grind it or combine it with other ingredients.

The Different Parts of the Coriander Plant

The coriander plant provides several ingredients that are used in cooking, each with its own flavour and culinary purpose. While the seeds are used as a spice, the leaves and roots are also widely used in many regional cuisines.

Coriander Leaves

Fresh coriander leaves are widely used as a garnish and flavouring herb in many cuisines. They have a bright, herbal flavour that differs greatly from the warm, citrusy notes of the seeds.
As their aroma diminishes quickly when exposed to heat, the leaves are usually added at the end of the cooking process or used raw in salads, chutneys and salsas.

Coriander Root

Coriander root is a popular ingredient in Thai and other Southeast Asian cuisines. It has a deeper, more concentrated flavour than the leaves, and is often crushed into curry pastes, marinades, and soups.

While the leaves and roots have their own culinary uses, coriander seeds are most often used as a spice and are valued for the depth and balance they bring to savoury cooking.

Whole vs Ground Coriander Seeds

Depending on the dish, coriander seeds can be used whole, crushed, or ground. Whole seeds release their flavour slowly during cooking and are often added at the start of a recipe. They are commonly used in pickling liquids, stews, and slow-cooked dishes, as the spice has time to soften and infuse the sauce.

Ground coriander disperses more quickly and is better suited to spice blends, marinades and sauces, where an even flavour is required. As ground coriander loses its aroma faster than whole seeds, many cooks prefer to grind the spice just before using it.

Toasting Coriander Seeds

Toasting coriander seeds before cooking intensifies their flavour and releases their natural oils. The seeds develop a slightly deeper, nutty aroma while retaining their citrus warmth.

To toast coriander seeds, place them in a dry frying pan over a medium heat and stir gently for a few minutes until they become fragrant. Once toasted, the seeds can be used whole, crushed or ground. Toasted coriander is particularly useful in spice blends, rubs, and roasted dishes.

Crushing or Grinding Coriander Seeds

Coriander seeds can be lightly crushed with a mortar and pestle, or ground into a powder using a spice grinder. This releases more of the seeds’ aroma than using them whole, while still leaving small fragments of spice within the dish.

Grinding them into a powder enables their flavour to blend smoothly into sauces and spice mixtures. Many traditional spice blends start with toasting and grinding coriander together with other spices.

When to Add Coriander During Cooking

The timing of adding coriander can influence how its flavour develops. Whole coriander seeds are usually added at the beginning of the cooking process to allow them to soften and release their aroma. They work particularly well in slow-cooked dishes such as curries, braises and stews.

Ground coriander, on the other hand, is usually added slightly later in the cooking process to prevent its delicate citrus notes from being lost during long simmering.

Tempering Coriander Seeds (Tadka)

Another common technique for using whole coriander seeds is tempering, which is known as tadka in Indian cooking. In this method, whole spices are fried briefly in hot oil or ghee at the start of the cooking process to release their aroma and flavour the fat.

Once the seeds begin to sizzle and become fragrant, other ingredients such as onions, garlic, ginger or chilli can be added to the pan. The infused oil then forms the flavour base of the dish.

Tempering is commonly used in Indian lentil dishes such as dal, as well as in vegetable curries and spice-based sauces. You can see this technique in Flaevor’s Spinach and Roasted Tomato Dahl recipe.

Cooking with Coriander in Different Dishes

Coriander seeds can be used in a wide variety of savoury dishes. Their citrus warmth helps to balance rich meats, earthy legumes, and roasted vegetables. They are commonly used with:

• Lamb, chicken and slow-cooked beef
• Lentils, chickpeas and other pulses
• Roasted vegetables, such as carrots, pumpkin and aubergine
• Rice and grain dishes
• Spice blends and marinades

Coriander pairs well with spices such as cumin, cardamom and turmeric, so it often forms part of the aromatic base of many traditional spice mixtures.
