Fresno peppers are a popular choice for making tasty salsas, spicy stir fry, or hot sauces. If the recipe you’re making calls for fresnos, but you don’t have any on hand, we’ve got you covered.
In this article, I’ll share the best fresno pepper substitutes. If you’re in a pinch, any of these options will fill in as an alternative. However, I put them in order from the best substitute to the…least-best.
1. Jalapeño peppers
People often mistake Fresno chiles for jalapeños, and they certainly do have a similar appearance. Jalapeño peppers make a great substitute for Fresno peppers in a pinch.
When it comes to flavor, jalapeños may be a bit more vegetal than fresnos. If you can find them, choose jalapeños that are red. Red jalapeños in are their ripe form and have more sugars than green ones. The flavor will be closer to a red Fresno too.
The heat level is similar between the two, even the size and shape is roughly the same. Where they differ is in heat level and thickness. Fresno peppers are slightly hotter than jalapeños, and have thinner skin.
2. Red bell peppers (plus cayenne powder)
Like I mentioned, Fresnos are sweeter than green jalapeños. Red bell peppers have a similar sweet profile to a Fresno, but lack heat. Add in a few pinches of ground cayenne pepper for spice and you’ve got yourself a replacement!
Green bell peppers are not as close for flavor, but can be used if they’re all you have. If you don’t have cayenne powder for adding heat, red pepper flakes, hot paprika, or another dried chile can fill in.
3. Serrano peppers
Another fresh pepper that can fill in for Fresnos is the serrano. This smaller pepper variety is very similar in heat level, but is commonly sold in its green form.
Serranos will eventually turn red when ripe, so if you happen to see any red peppers, choose those. However, green will do just fine, and they have a nice fresh, crisp flavor and plenty of heat.
4. Cayenne peppers
Cayenne peppers are hotter than Fresnos, but are still a good alternative. If your recipe primarily needs heat from the Fresnos, then cayenne peppers are a perfect substitute.
If the recipe needs Fresnos for crunch or texture, then cayennes might not be the best option. Fresh is always best, but if you only have dried cayenne, it can still work to deliver spice. Just be sure to adjust the proportions accordingly (start small and add more as desired for heat).
5. Red pepper flakes
If you don’t have access to any fresh peppers, you still have options! Red pepper flakes are a perfectly suitable alternative for Fresnos in a pinch.
The heat of red pepper flakes is medium (just like Fresnos), and they also have a great flavor. Red pepper flakes are commonly sun-dried, preserving their sweet and mildly-smoky flavor.
Of course, red pepper flakes aren’t going to give your dish much texture. If you’d like, consider adding another fresh ingredient with a similar crunch to a pepper (such as carrots, celery, or similar).
6. Frank’s RedHot sauce
While any hot sauce can be used to add heat, Frank’s RedHot is a simple, relatively neutral option. Just keep in mind that it contains garlic, so if your recipe doesn’t need it, choose another sauce.
Other sauces:
- Chili garlic sauce
- Tapatío
- Tabasco sauce
- Sweet chili sauce
Whatever hot sauce you have on hand can help add heat to your meal. Take a quick taste to make sure that the flavors of your sauce won’t compete with the overall vibe of the dish you’re cooking.
7. Sweet chili sauce
Last up is sweet chili sauce. As the name suggests, this sauce is very sweet. It is most often used as a dipping sauce for things like fried chicken or dumplings. However, if you happen to have it on your refrigerator shelf, it can be used as an alternative for Fresnos.
How spicy are Fresno peppers?
As I mentioned, Fresno peppers are comparably spicy to jalapeños. However, depending on the exact variety, they can be slightly hotter.
Generally speaking, Fresno peppers come in around 5,000-10,000 SHUs on the Scoville scale, making them slightly hotter than jalapeños.
Fresno peppers usually contain more seeds and innards than jalapeños, which is often removed. Without the inner membrane, I have found that Fresnos often taste less spicy than a comparable jalapeño.
In the end, it all comes down to the exact variety of Fresno you’re eating, where it was grown, and when it was harvested. Learn more about why peppers are spicy here.
Where to get Fresno chili peppers
While Fresnos are popular, they are not nearly as accessible as some other pepper varieties. Most traditional grocery stores in the US will offer jalapeños and habaneros for hot peppers, and not much else.
If you happen to live on the West coast, you may be more likely to come across them, given that the Fresno pepper was named after Fresno county, California. However, you may still have to do some searching to find them fresh.
Where to find Fresnos:
- Whole Foods (or other specialty grocery stores). Since Whole Foods aims to bring a wider variety of novelty foods to the masses, they often carry a better selection of peppers. I have personally seen Fresno chilis for sale here consistently for many years.
- Farmer’s Markets. If your timing is right (summer/fall), then you may get lucky and find fresh Fresno peppers at your local Farmer’s Market. Search for local weekend produce markets and you’ll probably find what you’re looking for (or something even better).
- Grow them at home. Growing peppers is a true joy that we want every spicy food lover to experience. If you want the best tasting (and hottest) peppers, you’ll just have to grow them from seed!
