Pasilla vs poblano: names, forms and substitutions

Is a pasilla pepper the same as a poblano?

Traditionally, no. A pasilla is the dried form of the chilaca chile. A poblano is a different chile that is usually sold fresh, and a dried poblano goes by another name, ancho. The confusion comes from the grocery aisle: in some US stores, fresh poblanos are labeled "pasilla." So the pepper in your cart may be a poblano even if the sign says pasilla.

Four names, two peppers

Name | Form | What it is

Chilaca | Fresh | The fresh chile that becomes pasilla once dried

Pasilla | Dried | Dried chilaca, described as smoky with a raisin-like flavor

Poblano | Fresh | A separate chile, mild and commonly used for stuffing

Ancho | Dried | Dried poblano

"Pasilla" or "green pasilla" on fresh produce | Fresh | Often a poblano sold under a retail name

Why fresh peppers labeled pasilla are often poblanos

The mix-up is a naming habit, not a botanical one. A food forum discussion focused on Los Angeles notes that some grocers call poblano peppers pasilla, and one produce reference catalogs the fresh pepper as "Green Pasilla (Poblano)." The evidence does not show how widespread this labeling is or which regions use it most, so treat any fresh "pasilla" sign as a prompt to check what you are actually buying. The simplest first clue is form: a true pasilla is dried, while a poblano is fresh.

Taste and heat

Fresh poblanos are mild. The produce reference that lists them as green pasilla puts them at 1,000 to 2,000 Scoville heat units, the standard scale for chile heat, which it describes as typically milder than a jalapeño. Dried pasilla has a different character, described as smoky and raisin-like. That heat figure applies to the fresh poblano, not to dried pasilla.

Chilaca vs poblano

Both are fresh chiles, but they are different peppers that follow parallel paths when dried: a chilaca becomes a pasilla, and a poblano becomes an ancho. If a recipe specifies one by name, the other is not the same ingredient.

What each pepper is used for

Fresh poblanos are well suited to stuffing. Dried pasillas are valued for their smoky, raisin-like flavor, which points to cooking where a dried chile's depth matters more than a fresh pepper's body.

Can you use pasilla instead of poblano?

• If the "pasilla" is a fresh green pepper in the produce section, it is likely a poblano under a regional label and should work wherever the recipe calls for poblano.
• If it is a dried pasilla, it is not a direct swap. It is a different chile in a different form, it cannot be stuffed like a fresh poblano, and it brings a smoky, raisin-like flavor instead of a fresh one.
• If your recipe wants a dried poblano, the name to look for is ancho, not pasilla.

Questions the available evidence doesn't settle

• How hot dried pasillas are: no heat figure was available for them.
• What to substitute for dried pasilla: no tested substitute was identified, and an ancho should not be assumed equivalent just because it is also dried.
• Which specific dishes traditionally use dried pasilla.
• Whether poblanos can be eaten raw.
• How to tell a fresh chilaca from a fresh poblano by appearance.
• Check an authoritative chile reference or a recipe's own guidance before relying on any of these.
