Characteristics of the Fresno Pepper

The Fresno pepper has glossy, waxy skin and starts green, then gradually changes from orange to red as it matures. Green peppers are around 2,500 Scoville Heat Units (SHU), and red peppers can reach up to 10,000 SHU.

Its shape is cone-shaped, similar to a jalapeno, though its shoulders are broader than the jalapeno. It also tastes like a jalapeno when raw but has a smoky flavor when cooked.

It’s worth noting that the Fresno is thinner-walled than a jalapeno, which makes it perfect for salsa or cooking in your favorite dishes. Some say it has a meaty aroma, like pepperoni when cooked in sauces.

Using the Fresno Pepper

The Fresno pepper was named after the county of Fresno, not the city.

The pepper was discovered in the 1950s by a grower and seed merchant named Clarence “Brownie” Hamlin, who lived in Clovis, California, which is not far from the City of Fresno, and part of Fresno County.

Today, it is a popular pepper grown throughout California and used in southwest cuisine. They’re found fresh in supermarkets, especially throughout the west coast. You can even buy fresh Fresno peppers on Amazon!

How to use the Fresno Pepper

Fresno peppers can substitute for jalapeno, chipotle, cayenne, and serrano peppers. Try Fresno peppers in these pepper recipes:


You can buy dried Fresno pepper flakes to add to your dishes, or drying them yourself is easy if you have an electric food dehydrator.

Thoroughly rinse your peppers, remove the stems and cores, cut into ⅜-inch sections, and place them in the dehydrator tray. Peppers normally take about eight to twelve hours to dry in a dehydrator.

You can still dry your peppers if you don’t have an electric dehydrator. If it’s 90 degrees or hotter, you can even dry them outside if the humidity is below 60 percent.

To sun dry your peppers, rinse and remove dirt, lay them on stainless steel, plastic, or Teflon-coated fiberglass drying screen trays, and place them on blocks to increase airflow. Do not use metal, copper, or aluminum trays.

Once the peppers are dry, pasteurize them to kill any insect eggs that may have infiltrated them. Pasteurize them by sealing them in a freezer bag and placing them in the freezer for 48 hours, or you can place them in the oven at 160 degrees Fahrenheit for 30 minutes.

If the weather isn’t appropriate for sun drying, you can dry them in the oven at 140 degrees Fahrenheit. Any temperature higher will cook, not dehydrate your peppers. It will take around 16 to 24 hours in the oven.

Be sure to let your peppers cool completely before storing them. Dried peppers can be stored in a cool, dark place for several months. Store them in moisture-free packaging such as a glass jar or freezer container.


Canned peppers are delicious and a great way to keep your peppers for a long time after the harvest season has passed. Use them on sandwiches, burritos, pizzas, flatbreads, and more!
