Hatch chile and Anaheim chile come from the same family of New Mexico pod-type peppers, but they differ in where they’re grown, how hot they are, and how they taste. The short version: Hatch chile is grown in New Mexico’s Hatch Valley and tends to be more flavorful and often hotter; Anaheim is a milder chile associated with California.

Both are long, green, mild-to-medium chiles that look similar on the shelf, which is why they’re so often confused. The differences come down to origin and intensity.

A shared ancestry

The Anaheim chile traces back to New Mexico. In the early 1900s, a farmer named Emilio Ortega brought New Mexico chile seeds to the Anaheim, California area, and the pod type grown there picked up the regional name. So Anaheim and Hatch chile are botanical cousins — both New Mexico pod-type chiles — that diverged by geography and, over time, by cultivar selection.

Hatch chile is defined by its origin: chile grown in the Hatch Valley of southern New Mexico. “Anaheim” describes a pod type and a general style rather than a verified growing region.

Heat

The most practical difference is heat:

  • Anaheim is reliably mild, generally landing in the lower hundreds to roughly 2,500 Scoville Heat Units (SHU).
  • Hatch chile spans a wider range. Milder Hatch cultivars sit in Anaheim territory, but hotter Hatch cultivars climb well above it — some rivaling or exceeding a jalapeño. Heat depends heavily on the specific cultivar and the growing season.

Because Hatch chile is grown in a hotter, higher-stress desert environment, the same cultivar often develops more pronounced heat and flavor in the Hatch Valley than it would elsewhere. The NMSU Chile Pepper Institute documents how growing conditions and cultivar drive these heat differences.

Flavor

Anaheim is mild and slightly sweet — an easy, crowd-pleasing chile. Hatch chile is prized for a deeper, earthier, more complex flavor that intensifies when roasted, which is why roadside roasters fire up across the Hatch Valley every harvest season.

Which should you use?

  • Choose Anaheim when you want a mild chile for stuffing (chiles rellenos), mild salsas, or dishes where you don’t want much heat.
  • Choose Hatch chile when flavor is the point — green chile sauce, stews, breakfast burritos, and anything where that roasted, southwestern character should lead.

If a recipe calls for Anaheim and you want more character, certified Hatch green chile is a natural substitute; just account for the potential jump in heat.
