Basil vs. Mint: Same Family, Different Flavor Chemistry

By · Reviewed · 18 sources

basil vs mint

Basil and mint are cousins in the same plant family, yet one tastes sweet and spicy and the other tastes cool. Their flavors come from different compounds: sweet basil oil is built on methyl chavicol (estragole), while the two kitchen mints run on menthol and menthone (peppermint) or carvone (spearmint). They’ll swap in some savory dishes, but never in mint tea or a basil pesto. The rules for Basilico Genovese PDO go so far as to require a total absence of mint aroma in the leaf.1

French-type basil oil is sweet-spicy, slightly green and fresh, and spearmint is minty but not pungent. For which mint is which, see mint and types of mint.

The differences that change a dish

Coolness

Mint’s cooling character comes with menthol, and only peppermint has much of it. McCormick describes spearmint as milder than peppermint and lacking menthol, and Britannica names carvone as spearmint’s main component.46 You’ll see spearmint described as having “a strong menthol flavor,” but the sources we reviewed say the opposite. Basil has no cooling note at all, so it can’t replace mint where coolness is the point: tea, a mojito, mint chocolate.

Which basil

“Sweet basil” is the species Ocimum basilicum. Genovese is one cultivar group within it, not another name for the whole species; a US trial of commercial basils lists ‘Genovese’ among the O. basilicum cultivars.7 The protected Basilico Genovese PDO goes further and requires a total absence of mint aroma in the leaf.1 That tells you how differently the two herbs get judged. See Genovese basil.

Heat and drying

Both are delicate. Basil and mint are among the herbs best added in the last minute or two of cooking. America’s Test Kitchen lists both among herbs that lose a lot of flavor when dried,8 and its tests describe delicate herbs like basil as more volatile.9 Dried common basil is less fragrant and more pungent than fresh. Dried basil can go into long-cooked sauces, and dried mint into recipes written for it, but neither replaces the fresh leaf as a garnish.

Nutrition

Source: USDA FoodData Central;1011 the percentages are our math against FDA Daily Values.12 A comparison that gets passed around credits 100 g of basil with 175% of daily vitamin A and spearmint with 135%. Against today’s Daily Values, the figures are 29% and 23%. You’ll use a few grams at a time, so neither herb is a meaningful source of these nutrients in normal cooking. Basil’s vitamin K is the exception (see the basil profile).

Can one stand in for the other?

Partly. More options are on our mint substitutes page.

  • Basil in place of mint. Ratio (Method): When mint is just a fresh green herb in a salad, yogurt sauce or herb sauce, start with about half the mint amount and add more to taste, at the end of cooking. Basil brings sweetness and green freshness but not mint’s coolness, so leave it out of mint tea or a mint dessert. The peppermint substitutes page lands in the same place for peppermint.
  • Mint in place of basil. Ratio (Method): In a herb salad, a Southeast Asian noodle dish or a fruit salad, start with about half the basil amount, since mint is the pushier flavor. In a mint-and-herb pesto it makes a different sauce, not a stand-in, and in a long-simmered tomato sauce it tastes out of place.

How each is used

  • Basil. In Italian cooking the leaves go into pizzas, pasta, chicken and cheese dishes, and pesto. Sweet basil is also an important ingredient of Thai cuisine. See basil uses and cooking with basil.
  • Mint. Spearmint leaves flavor many foods, especially sweets. By Katzer’s account, peppermint goes almost entirely into confectionery and sweet liqueurs.13 Saveur describes English mint sauce as a simple mix of fresh mint, sugar and vinegar,14 and by long custom it’s served with roast lamb. Peas, potatoes, yogurt and fruit are common pairings. See mint uses and cooking with mint.

What isn’t known

  • We found no source for the popular idea that mint is mainly a Middle Eastern or Asian herb and basil a Mediterranean one. Both show up across many cuisines.
  • We found no dated, sourced price comparison.
