Dried vs Fresh Herbs Substitution (With Ratios)
Use 1 tsp dried herbs for every 1 tbsp of chopped fresh herbs, a 1:3 ratio. If the dried herb is finely ground rather than crumbled, use about 1/2 tsp, because ground herbs pack more tightly into a spoon.
Herb-by-herb substitution chart
| Herb | Fresh amount | Dried equivalent | Best for | Notes |
|---|---|---|---|---|
| Oregano | 1 tbsp | 1 tsp | Tomato sauce, pizza, Greek dishes | Dries beautifully; often preferred dried |
| Thyme | 1 tbsp leaves (about 6 sprigs) | 1 tsp | Stews, roasts, soups | Holds flavour well when dried |
| Rosemary | 1 tbsp chopped | 1 tsp, crumbled | Roast meats, potatoes, bread | Dried needles are tough; crush or grind |
| Sage | 1 tbsp chopped | 1 tsp crumbled or 1/2 tsp rubbed | Stuffing, pork, brown butter sauces | Dried is strong and slightly musty |
| Marjoram | 1 tbsp | 1 tsp | Sausage, soups, eggs | Milder cousin of oregano |
| Basil | 1 tbsp | 1 tsp | Long-simmered sauces only | Loses its sweet, clove-like aroma when dried |
| Parsley | 1 tbsp | 1 tsp | Soups, stews | Dried is faint; adds colour more than flavour |
| Dill | 1 tbsp | 1 tsp | Dressings, potatoes, fish | Fair when dried; add near the end |
| Tarragon | 1 tbsp | 1 tsp | Chicken, béarnaise, vinaigrettes | Dried loses some anise brightness |
| Mint | 1 tbsp | 1 tsp | Middle Eastern dishes, lamb, tea | Dried mint is a staple in many cuisines |
| Bay leaf | 1 fresh leaf | 2 dried leaves | Stocks, braises | Fresh leaves are more potent |
| Chives | 1 tbsp | 1 tsp freeze-dried | Dips, eggs | Freeze-dried keeps more flavour than air-dried |
| Cilantro | 1 tbsp | Not recommended | — | Dried cilantro has almost no flavour |
Why the ratio is 1:3
Fresh herb leaves are roughly 80–90% water. When they dry, they shrink dramatically, so a teaspoon of dried leaves holds about as much herb as a loosely packed tablespoon of fresh. Their aroma molecules, now concentrated, deliver similar flavour in a third of the volume.
Why some herbs dry better than others
An herb's flavour lives in essential oils stored in tiny glands (trichomes) on its leaves. The two big groups behave differently:
- Woody, Mediterranean herbs (oregano, thyme, rosemary, sage) evolved in hot, dry climates. Their aroma compounds, like thymol and carvacrol, are relatively stable and sealed in tough leaves, so they survive drying well.
- Tender herbs (basil, cilantro, parsley, chervil) carry delicate, highly volatile compounds that evaporate or oxidize during drying. Dried versions taste flat or hay-like.
Dried herbs also need time. Their oils have to rehydrate and diffuse into fat or liquid, which is why they belong at the start of cooking. Fresh tender herbs lose aroma with heat, so they go in at the end.
When NOT to swap
- Raw, herb-forward dishes like pesto, chimichurri, salsa verde, tabbouleh and gremolata need fresh herbs. There's no dried equivalent.
- Garnishes add colour and fresh aroma; dried herbs can't do either.
- Cilantro, chervil and basil in fresh dishes: skip the dried versions entirely.
- Going fresh for dried? Use 3 times the amount and add woody herbs early, tender ones late.
Questions
What is the ratio of dried herbs to fresh?
Use 1 part dried to 3 parts fresh: 1 tsp dried herbs replaces 1 tbsp chopped fresh. For finely ground dried herbs, use about 1/2 tsp.
How many fresh thyme sprigs equal 1 tsp dried thyme?
About 6 sprigs of fresh thyme give roughly 1 tbsp of leaves, which equals 1 tsp dried thyme.
When should I add dried herbs while cooking?
Add dried herbs early, with the fat or liquid, so they have at least 10–15 minutes to rehydrate and release their oils. Add tender fresh herbs at the end.
How long do dried herbs last?
Dried leafy herbs keep good flavour for about 1 year and ground ones for about 6 months. Rub a pinch between your fingers; if it barely smells, replace it.
