You can use fresh thyme instead of dried thyme at a ratio of 1 tbsp fresh per 1 tsp dried. Fresh thyme replaces dried at 1 tablespoon of fresh for every 1 teaspoon of dried, and in a roast or a soup the dish gains a brighter, greener note. The swap is easy, because thyme is a forgiving herb in both forms.

All amounts in this guide are approximate. Taste as you go, adjust to your dish, and verify with a kitchen scale where weighing matters, because a spoonful can vary with how full it is and how finely the ingredient is ground.

Worked examples

A roast pork that calls for dried thyme

A roast pork recipe asks for 1 tablespoon of dried thyme rubbed into the skin with salt. Use 3 tablespoons of fresh thyme leaves instead, chopped with the salt and rubbed in the same way. The fresh herb perfumes the crackling as it roasts, and the pork comes out fragrant and golden. The fresh leaves may darken in the oven, but they still flavour the meat, and the roast tastes fresher than the dried version.

A mushroom soup for a starter

A mushroom soup recipe uses 2 teaspoons of dried thyme simmered with the mushrooms. Swap in 2 tablespoons of fresh thyme leaves, added in the last ten minutes of cooking. The soup keeps its deep, earthy base, but the fresh thyme adds a bright herbal lift that makes the mushrooms taste more like themselves. It is a lighter, fresher soup, and it suits a first course better than the heavier dried version.

A tray of roasted carrots and parsnips

A roasted root vegetable recipe calls for 1 teaspoon of dried thyme tossed with the vegetables. Use 1 tablespoon of fresh thyme leaves instead, scattered over the tray halfway through roasting. The leaves crisp in the oven without scorching, and the vegetables come out fragrant and caramelised. Adding the fresh thyme halfway through, rather than at the start, protects its flavour from the long roast.

What changes in the result

The flavour turns brighter and greener, with a slightly minty lift that dried thyme loses. In a soup or a roast that is an improvement, because the dish tastes fresher and more alive. The texture changes too: fresh thyme leaves are soft and small, and they melt into the dish, while dried thyme stays crumbly. The colour improves, with green flecks where the dried herb was grey. The one thing that gets worse is shelf life: a dish finished with fresh thyme should be eaten the same day, while a dish made with dried thyme keeps its flavour for days.

When not to substitute

Do not substitute dried herbs for fresh in salads, garnishes or dishes where the herb is eaten raw. If the recipe depends on dried thyme for its defining flavour or structure, do not make the swap at all. Buy the missing ingredient instead, because a substitution that changes the dish into something else is not a substitution worth making.

Where it works best, and where it does not

Fresh thyme shines in roasts, soups, grilled vegetables and any dish where it goes in late and the leaves stay visible. It is at its best in spring and summer, when the plant is growing fast and the leaves are tender. It fails in a dish that simmers for hours, such as a slow stew, where its delicate flavour cooks away and the dish ends up tasting of nothing; there, dried thyme is the better herb, and fresh thyme belongs only in the last ten minutes.

How to use it well

Strip the leaves from the woody stems before using fresh thyme, because the stems are too tough to eat. Add the leaves late, in the last ten minutes of cooking, so their flavour survives. Use three times as much fresh as the dried amount, and taste before serving, because fresh thyme varies with the season. Store fresh thyme in the fridge wrapped in a damp cloth, where it keeps for two weeks, which is longer than most fresh herbs. If you have a glut of thyme, dry it yourself by hanging small bunches upside down in a dark, airy place.

Frequently asked questions

How much fresh thyme replaces dried thyme?

Use 1 tablespoon of fresh thyme for every 1 teaspoon of dried thyme. A recipe calling for 1 tablespoon of dried thyme needs 3 tablespoons of fresh thyme leaves, and a recipe calling for 2 teaspoons of dried thyme needs 2 tablespoons of fresh. Strip the leaves from the stems first, because the stems are woody and inedible.

When should I add fresh thyme while cooking?

Late, in the last ten minutes, or halfway through a roast. Fresh thyme's flavour fades in a long simmer, while dried thyme needs the long simmer to soften. The two herbs want opposite treatment, so do not just swap the amount: swap the timing too. Add fresh thyme near the end and it will reward you.

Does fresh thyme taste stronger than dried?

No, it tastes brighter but not stronger. Dried thyme is more concentrated by volume, which is why you need three times as much fresh. The fresh herb gives a greener, slightly minty flavour, while the dried herb gives a warmer, earthier one. In a stew the dried version can taste stronger; in a roast the fresh version can taste brighter. Neither is better in every dish.

Can I use the thyme stems?

Not to eat, but yes to flavour. The woody stems are too tough to chew, so strip the leaves for the dish and use the bare stems in a bouquet garni for a stock or a stew, tied up and fished out at the end. The stems carry flavour even without leaves, so do not throw them away until the stock is done.

How do I dry thyme at home?

Cut small bunches, tie them with string, and hang them upside down in a dark, airy place for one to two weeks until the leaves are crisp. Strip the leaves into a sealed jar and store it away from light. Home-dried thyme is often stronger than shop-bought, because it is fresher, so start with a little less than the recipe says and taste.

Thyme is one of the easiest herbs to dry because its small leaves lose moisture quickly and evenly. Avoid drying it in direct sunlight, which bleaches the colour and dulls the flavour, and do not use a hot oven, which can scorch the leaves before they are fully dry.
