A recipe asks for a teaspoon of dried thyme. The jar is empty. What goes in instead depends less on which herbs look alike on the shelf and more on what the thyme was doing in that particular pot.
Thyme is woody, faintly peppery, a little medicinal in the way that reads as savory rather than sweet — the thymol in it is the same compound that gives the herb its sharp edge when you crush a leaf between your fingers. It is also one of the very few leaf herbs that dries well. Basil and parsley collapse into green dust. Thyme keeps most of its character, which is why dried thyme sits in a braise for ninety minutes and still tastes like thyme at the end.
That durability matters for substitution. Most of the herbs you'll reach for instead are more volatile than thyme, and they need to go in later, or in different amounts, or both.
First, the fresh-to-dried math
The standard conversion is 3:1 by volume. One tablespoon of fresh thyme leaves equals one teaspoon of dried. Going the other direction, a recipe calling for a teaspoon of dried wants a tablespoon of fresh, stripped from the stems.
Recipes rarely measure fresh thyme in spoons, though. They say sprigs. A four-inch sprig with decent leaf coverage strips out to roughly half a teaspoon of leaves; a thin, woody one gives you closer to a quarter. So six average sprigs is about a tablespoon, which is about a teaspoon dried. If a braise calls for four sprigs of fresh thyme and you have only the jar, ¾ teaspoon dried is the honest answer, and a full teaspoon is fine because thyme is not an herb that bullies a dish.
Ground thyme is a separate item and a stronger one per spoonful, since you're not paying volume for the air between leaves. Use about ⅔ teaspoon ground where the recipe wants a teaspoon of dried leaf, and add it late enough that it doesn't scorch — ground herb has far more surface area than leaf and will turn bitter in a dry pan in under a minute.
Marjoram: the substitute that actually works
Marjoram and thyme are not the same plant or the same family branch, but they land in the same place on the palate: savory, slightly floral, no anise, no camphor blast. Marjoram is softer and sweeter, with a rounded edge where thyme has a sharp one. Substitute it at 1:1 and most people at the table will not identify what changed.
The catch is heat tolerance. Marjoram's aromatics are fragile and a long simmer flattens them. If you're adding it at the top of a two-hour braise the way you would thyme, go up to 1¼ teaspoons per teaspoon of thyme, and stir in another ¼ teaspoon in the last ten minutes to put the top notes back. In a vinaigrette, a pan sauce, or anything that cooks under twenty minutes, straight 1:1 is correct.
Oregano at three-quarters, and not everywhere
Oregano is the substitution most people make, because most people have it. It works, with an adjustment: oregano carries carvacrol where thyme leans on thymol, and the result is louder, more pungent, more obviously herbal. Use ¾ teaspoon of dried oregano for every teaspoon of dried thyme. If the dish is delicate — a cream sauce, a poached fish, a potato gratin — drop to ½ and taste before adding more.
Use Mediterranean oregano, not Mexican. Mexican oregano's citrus-and-brush profile pulls a French or New England dish somewhere it wasn't going.
Oregano also handles long cooking about as well as thyme does, which makes it the easy pick for stews, tomato sauce, bean pots and roast chicken. It is the wrong pick for anything that reads as Provençal or Creole, where you'll notice the substitution immediately.
- Tomato sauce, bean pots, braised lamb, roast potatoes: oregano at ¾, added early
- Chowder, cream sauces, egg dishes, delicate fish: oregano at ½, or skip to marjoram
- Greek and Italian dishes where thyme was a background note anyway: oregano at 1:1 and don't think about it
The mixes, and what each one drags in with it
Every blend that contains thyme also contains three or four other things, and those other things arrive whether you want them or not. The trick is knowing which passenger is loudest.
- Herbes de Provence — thyme, savory, rosemary, marjoram, often oregano, sometimes lavender and fennel seed. Thyme makes up roughly a quarter of it, so substitute 1:1, but cap the total at 2 teaspoons in a dish serving four to six. Past that, the rosemary and lavender stop being background. If you need more than 2 teaspoons, make up the difference with oregano.
- Italian seasoning — basil-forward, plus oregano, rosemary, marjoram and a little thyme. Substitute 1:1. It works in anything tomato-based, on roast chicken and in meatballs. It does not belong in clam chowder or a French braise, where the basil sticks out.
- Poultry seasoning — dominated by sage, with thyme and marjoram behind it. Use ½ teaspoon per teaspoon of thyme. Excellent in stuffing, gravy, pork and squash. Sage is the loudest herb in the cabinet and half is genuinely enough.
- Za'atar — thyme-family herb plus sesame, sumac and salt. Don't substitute it into a cooked dish. The salt content varies by blend, the sesame burns, and the sumac goes dull with heat. Keep it for finishing.
- Bouquet garni sachets — usually thyme, bay, parsley, sometimes peppercorns. Closest thing to a straight swap. One sachet stands in for about a teaspoon of dried thyme plus the bay leaf the recipe probably also wanted.
Savory, and the rest ranked honestly
Summer savory is the sleeper. It's peppery, slightly resinous, and it sits so close to thyme that bean-cooking traditions across southern France and the Balkans use them almost interchangeably. Swap at 1:1. Winter savory is more pine-like and stronger; use ¾.
Below that, you're no longer substituting so much as redirecting the dish, which is sometimes the right call.
Rosemary: ⅓ teaspoon per teaspoon of thyme, crushed or chopped fine so you don't get needles. Good with lamb, potatoes and white beans. Overwhelming in anything else. Sage: ½ teaspoon, and only for pork, beans, winter squash or brown butter. Tarragon: ½ teaspoon, and only in chicken, fish, eggs or cream — it brings anise, and either that fits or it doesn't. Dried basil: 1:1, tomato dishes only, added in the last ten minutes because it has nothing left after a long simmer. Dried parsley and dried dill are not substitutes for thyme in any dish; one contributes almost nothing and the other contributes something entirely different.
Dishes where you should just go buy thyme
Jerk seasoning is thyme, allspice and scotch bonnet, and removing any one of the three doesn't give you a variation — it gives you something else. Same with New England clam chowder, where thyme is the only herb in the bowl and its absence is a hole rather than a difference. Creole and Cajun cooking runs thyme and oregano together, so substituting oregano for the thyme just doubles one voice and deletes another.
Coq au vin, beef bourguignon, cassoulet and any stock built on a bouquet garni are all thyme-structured. You can push through with marjoram at 1¼ and nobody will call the police, but the finished dish will taste rounder and less savory than it should. These are the cases where a jar of dried thyme earns its shelf space — it keeps its character for a good eighteen months in a sealed jar away from the stove, which is longer than most of what's up there.
How to add whatever you landed on
Crush dried leaf herbs between your palms on the way into the pot. It takes two seconds and breaks open the leaf structure so the aromatics have somewhere to go. This matters more for substitutes than for thyme itself, because you're usually working with less of them.
If you're blooming in fat, keep the heat at medium and give leaf herbs 20 to 30 seconds — they have far more surface area than whole seeds and will go from fragrant to acrid fast. Better in most cases: add the fat, the aromatics, then the herb, then the liquid within half a minute.
Timing by herb: thyme, oregano, savory and rosemary all go in early and improve over 30-plus minutes of simmering. Marjoram, basil and tarragon go in during the last ten minutes, or split — half early for depth, half late for aroma. Sage can go either way but gets muskier the longer it cooks, so if you're using it at ½ strength, put it in with 15 minutes left.
Common questions
How much dried thyme equals one sprig of fresh?
About ¼ to ½ teaspoon of stripped leaves per four-inch sprig fresh, which converts to roughly ⅛ to ⅙ teaspoon dried. In practice: four fresh sprigs ≈ ¾ teaspoon dried, six sprigs ≈ 1 teaspoon dried.
Can I use fresh oregano in place of dried thyme?
Yes, at 2¼ teaspoons fresh oregano per teaspoon of dried thyme — that's the 3:1 fresh-to-dried conversion applied to the ¾ oregano ratio. Add fresh oregano in the last 15 minutes rather than at the start.
Is Italian seasoning close enough to thyme for a rub?
For chicken, pork or roast vegetables, yes, at 1:1. It reads as basil-and-oregano rather than thyme, which suits Mediterranean-leaning dishes and clashes with French or New England ones.
What's the best substitute if I want nobody to notice?
Marjoram at 1:1 in short-cooking dishes, 1¼ in long ones with a final ¼ teaspoon stirred in at the end. Summer savory is a close second at 1:1.
Does ground thyme work the same as dried thyme leaves?
Use about ⅔ as much by volume, since ground packs denser. Add it later in cooking than you would leaf thyme, and never toast it dry in a hot pan — it scorches in well under a minute.
