Fresno
Also known as: fresno pepper, fresno chile
The Fresno pepper looks almost identical to a red jalapeño and is frequently confused with one. Bred in Fresno, California in 1952, it has slightly different flavor and a marginally hotter heat profile, with a smokier, fruitier character that makes it a craft hot sauce favorite.

Bright, slightly fruity, with a clean medium heat — like a red jalapeño with more fruit and less vegetal character.
The Fresno is one of the most useful peppers most people have never heard of. At a glance it looks like a red jalapeño; in the kitchen it behaves like a slightly fruitier, slightly hotter version. Craft hot sauce makers favor it for that fruit character — Hot Ones' Yellowbird and Cholula's Hot Sauce both use Fresno or Fresno-derived peppers. Whole Foods and other higher-end grocers stock fresh Fresnos year-round; mainstream stores are catching up. Worth knowing as both a substitute and a primary ingredient.

Bright red (occasionally green when unripe)
Did you know
The Fresno pepper was first developed by Clarence Brown Hamlin in 1952 at the California Department of Agriculture in Fresno. It was registered specifically as a milder, sweeter alternative to red jalapeños for the canning industry — though today it's more often used fresh.

Container-friendly
Easy to grow — behaves similarly to jalapeño with a slightly more upright plant habit. Plants are productive (20–30 pods per season) and start producing earlier than chinense varieties. Container-friendly with a 3-gallon pot. Harvest fully red for the characteristic Fresno flavor; green Fresnos taste closer to green jalapeño.

If your grocer stocks 'red jalapeños' and they look glossy and slightly fatter than green jalapeños, there's a decent chance they're actually Fresnos. The two are often labeled interchangeably in mainstream stores. Either works for most recipes.
History & origin
Where fresno comes from
Clarence Brown Hamlin developed the Fresno cultivar at the California Department of Agriculture as a more uniform, slightly milder alternative to red jalapeños for industrial canning. The pepper found its commercial niche fresh rather than canned and has steadily gained popularity at upscale grocers since the 2000s. The combination of red jalapeño appearance with a slightly fruitier flavor has made it a favorite of craft chefs and sauce producers.

Frequently asked
Common questions about fresno
Is a Fresno pepper the same as a red jalapeño?
Different cultivars, but very similar. Fresno was bred separately from jalapeño in 1952. The pepper looks almost identical to a ripe red jalapeño but is slightly fruitier in flavor and a touch hotter on average. Most grocers don't distinguish, and they're often interchangeable in recipes.
How spicy is a Fresno?
Medium — 2,500 to 10,000 Scoville Heat Units. That's the same range as jalapeño but biased toward the high end. Most Fresnos taste hotter than typical green jalapeños but milder than serrano. Predictable heat with a noticeable fruit note.
Can you eat Fresno peppers raw?
Yes — that's their most common use. Sliced raw into salsas, pico de gallo, pickled toppings, and salads. The flavor is bright and fruity raw; roasting deepens it but isn't necessary. The thin walls work well for quick pickling (5 minutes in hot vinegar with sugar).
What hot sauces are made with Fresno peppers?
Several craft sauces feature Fresno specifically — Hot Ones' first season sauces drew heavily from Fresno, and brands like Truff, Yellowbird's Serrano, and various small-batch producers use Fresno as the base. Many 'red jalapeño' sauces are actually Fresno-based without distinguishing in marketing.
