5 Top Substitutes for Fresno Peppers

1 - Jalapeno Peppers

Jalapeno peppers are the go-to swap when you're out of Fresno peppers. They're just about everywhere, and chances are, you've already got some in your fridge.

They bring a similar heat level - not too mild, not too hot (roughly 2,500-8,000 Scoville Heat Units). Jalapenos are great because they mix well in most dishes without overpowering other flavors.

If you're looking to mix things up or if Jalapenos are what you need to substitute next time, check out easy air-fryer jalapeño poppers.

2 - Chipotle Peppers

Chipotle peppers are smoked, dried jalapenos that pack a punch with their smoky flavor (the same species, Capsicum annuum). They're a superb Fresno pepper substitute when you want to add a bit of smoky heat to your dishes.

While they're a bit spicier, they won't knock your socks off. Chipotles fit perfectly in sauces, stews, and meats.

Use half the amount you would for Fresnos since they're more intense; see chipotle powder alternatives for smoky heat.

Swap out one Fresno for half a Chipotle to keep things balanced. Plus, they're usually found canned in adobo sauce, adding extra richness to whatever you're cooking up.

3 - Serrano Peppers

Serrano peppers are a solid pick if you need more Fresno peppers (typically hotter, about 10,000-23,000 Scoville Heat Units).

The cool thing about Serranos is their crisp freshness, making them a top choice for adding a kick to salsas and dips. You'll want to use them more sparingly, though.

For every Fresno pepper your recipe needs, go for about three-quarters of a Serrano.

And hey, if you find yourself getting cozy with Serranos and need a backup for these guys, consult Serrano substitutes for easy swaps.

4 - Poblano Peppers

Poblano peppers are your buddy, while Fresno peppers are MIA (a mild Mexican pepper, Capsicum annuum, traditionally from Puebla).

Poblanos are awesome because they have a rich, earthy flavor that goes well in stuffed recipes or chili. You'll need more of them, though, since they're less hot.

And if Poblanos becomes your new fave but you run out, see easy air-fryer roasted poblano peppers.

5 - Red Pepper Flakes

Red pepper flakes are your secret weapon when Fresno peppers are nowhere to be found. They're the go-to for adding that fiery kick without making things complicated.

The beauty of red pepper flakes lies in their versatility - a little goes a long way in pizzas, pasta, and pretty much anything that needs a spice boost (often made from cayenne, ~30,000-50,000 Scoville units).

You'll need to go easy with these guys; use about half a teaspoon for each Fresno pepper your recipe calls for.

Plus, if red pepper flakes are all you've got and you're fishing for more ideas, explore red wine vinegar alternatives for bright acidity.
