How to Use Coriander Seeds in Cooking

Coriander seeds are a highly versatile spice used in 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, the aroma of which develops gradually during cooking. Knowing how coriander behaves when cooked will help you decide whether to toast, grind or combine it with other ingredients.

The Different Parts of the Coriander Plant

The coriander plant provides several ingredients used in cooking, each of which has its own flavour and culinary purpose. The seeds are used as a spice, while the leaves and roots are widely used for cooking and garnishing.

Coriander Leaves

Fresh coriander leaves are widely used as a garnish and flavouring herb in many cuisines, and are often added to dishes to enhance their flavour and aroma. They have a bright, herbal flavour that differs greatly from the warm, citrusy notes of the seeds.

Since their aroma diminishes quickly when exposed to heat, the leaves are typically added at the end of the cooking process or used raw in dishes such as 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 or pounded into curry pastes, marinades, and soups.

The roots are particularly valued for the earthy, aromatic flavour they impart to dishes such as Thai curry pastes, where they are commonly combined with garlic and white pepper.

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)

A ‘tadka’ is an important Indian cooking technique where whole spices are briefly added to hot oil or ghee, which sizzles and releases their aroma and flavour into the fat. The tadka is then stirred through or poured over a finished dish as a way to make the existing spice flavours even more intense.

The use of tempering is well-known in Indian cuisine, particularly in dishes like dal, as well as in vegetable curries and spicy sauces. You can see this technique in Flaevor’s Spinach and Roasted Tomato Dal recipe.

Common Food Pairings for Coriander Seeds

The warm, citrusy aroma of coriander seeds helps to balance rich meats, earthy legumes and roasted vegetables. However, they can also be used to add a unique touch to sweet recipes, particularly baked goods, fruit compotes and spiced syrups. Some classic flavour pairings include:

• 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

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