Oregano Uses: Sauces, Greek Food, Chili and Chimichurri

Oregano is one of the few herbs cooks often prefer dried. Across 24 recipes in America’s Test Kitchen’s fresh-versus-dried tests, chili was the one dish where tasters liked the dried herb better.¹ It’s essential in Italian pizza and pasta sauces, Greek salads and gyros, and it carries plenty of Latin American cooking too, from chili powder to a chimichurri made with 3/4 cup of fresh leaves. For timing, amounts and prep, see cooking with oregano.

Italian: pizza and pasta sauces

Oregano is essential in Italian pizza and pasta sauces. It’s also one of the five herbs in the USDA’s purchase spec for Italian seasoning, with thyme, rosemary, sage and basil.¹⁰ For a cooked tomato sauce, dried oregano makes sense. ATK found that dried oregano, rosemary, sage and thyme held up reasonably well in recipes that cooked more than 20 minutes with plenty of liquid.¹ ATK also cooked tomato sauce with both Mediterranean and Mexican oregano and noticed minimal differences.¹¹ Fresh leaves scattered over a pizza after baking come down to taste. See good spices for pizza, Italian seasoning and Italian spices.

Greek and Middle Eastern

Greek salad and gyros. Oregano is essential to both. Jennifer Segal’s home gyro recipe seasons the meat with 2 teaspoons of dried oregano.³ See gyro spices.
Greek seasoning. America’s Test Kitchen’s homemade blend uses 2 tablespoons of dried oregano and suggests it for salad dressings, feta, baked potatoes and grilled chicken.⁴ That’s three of oregano’s old standbys in one line: the vinaigrette, the roast potato and the grilled bird. See Greek seasoning.
Middle Eastern cooking. Oregano is a key ingredient there too. See Mediterranean spices.

Latin American: chimichurri, chili, beans and pozole

Chimichurri. Chimichurri is a sauce of Argentine origin that usually includes parsley, oregano, garlic and red wine vinegar. Argentines put little besides salt and pepper on their steaks, Britannica says, and chimichurri is the big exception. In Argentina, fresh parsley, garlic, oregano and chiles form the base; elsewhere in Latin America, coriander is popular.¹² Francis Mallmann’s version in Saveur uses 3/4 cup of finely chopped fresh oregano to 1 cup of parsley, with garlic, chile flakes, olive oil and red wine vinegar, and Saveur pairs it with steak, vegetables and bread off the grill.⁶ These recipes call for fresh oregano. Dried can stand in if that’s what you’ve got.

Chili and chili powder. Saveur’s chili con carne cooks oregano with the cumin and flour until fragrant.⁵ The USDA spec for chili powder lists ground chile, cumin, oregano, salt and garlic powder.¹⁰ Chili is also where ATK’s tasters preferred dried oregano to fresh.¹ See chili powder.

Black beans. Saveur’s Cuban-style black beans simmer with a single sprig of fresh oregano.⁷ See Cuban spices.

Pozole. In Pati Jinich’s red pozole, dried oregano is one of the traditional garnishes set out at the table, alongside lime, radish, lettuce, onion, ground dried chile and tostadas.⁸

Which oregano? Mexican oregano comes from a different plant. ATK found it stronger than Mediterranean oregano, with a hint of menthol, but in tomato sauce and mojo-marinated skirt steak it noticed minimal differences between the two.¹¹ So use what a recipe names when you have it, and swap freely when you don’t. See Mexican oregano vs. oregano.

French: herbes de Provence

The Label Rouge recipe for herbes de Provence is 26% oregano, with equal shares of savory and rosemary and 19% thyme.⁹ See herbes de Provence.

Rubs, marinades and dressings

Dry rubs. The University of Delaware suggests crushing dried herbs first to release some of their oils.¹³ So rub dried oregano between your palms, or grind it, before you mix it into a rub. A finer grind may spread more evenly, too, though we found no test of that.
Marinades. ATK’s oregano comparison used a mojo marinade for skirt steak.¹¹ Chimichurri’s olive oil and red wine vinegar⁶ make the same kind of marinade base.
Vinaigrettes. ATK’s Greek seasoning is meant for salad dressings.⁴

Oregano oil and pesto

Homemade oregano oil and oregano pesto are both herbs in oil. Oregon State University Extension says those mixtures can carry Clostridium botulinum and have to be refrigerated and used within 4 days, or frozen.¹⁴ You can pound oregano into a pesto like basil pesto, with garlic, oil and cheese, though we didn’t find a named recipe to point you to.
