Fresno hot sauce recipe

Like many other peppers, Fresno peppers ripen from green to red. They are edible at any stage, but we prefer them when they reach their most mature stage – fiery red. This is when the pods are spiciest and most flavorful. Thankfully, this is how they are harvested and shipped commercially, so you’re unlikely to find them in their unripe green form.

Fresno peppers have slightly thinner walls than jalapeño peppers, making them perfect for hot sauce recipes like this one. We also like using Fresno peppers in salsa recipes, or smoking them on the grill.

About the ingredients

  • Fresno peppers – While we always recommend growing your own peppers, Fresno peppers are easily found in many grocery stores. Look for ripe, red Fresno peppers that are firm (not mushy or soft). Do not use green Fresno peppers for this recipe as the flavor will be too vegetal.
  • Red bell pepper – Bell pepper adds volume to this hot sauce while also contributing to the beautiful red color. We also love the subtle sweet flavor it adds to this recipe.
  • Vinegar – White vinegar works best in this recipe. It helps create a pourable consistency while also adding needed acidity in this hot sauce.
  • Garlic – Most of our hot sauces contain garlic, and for good reason. Just a small amount adds great depth and flavor to this sauce.
  • Onion – For this recipe, we like using yellow or white onion. After charring on a cast iron skillet, the flavor and bite of the onion significantly mellows out, melting into a smooth sweetness.
  • Smoked paprika – Smoked paprika contributes to the fiery color of this sauce while adding interest and complexity. You can also used plain paprika if you want less smokiness.
  • Salt – Start off with 2 tsp of salt and then add more as desired.

  1. I love this recipe and will try it out, I love spicy food myself. In Africa we love spicy food and whenever I’m making my African stew, freshno pepper is my go to for the colour , spicy nature and thickness it gives to stew. Thank you for this wonderful recipe.

  2. 5 stars
    Excellent recipe, the charring and smoked paprika (made from my own Pepper
    Geek “Jimmy Nardello” seeds) really give it that extra level. I also fermented mine like all of my hot sauces but did add vinegar at bottling time just for the flavor profile change. It has the perfect level of heat and as gifts people rave about it. Charred ripe fresh red peppers are the best!

  3. 5 stars
    I made a batch of the Fresno Pepper sauce today, I love the flavor. Several months ago I made the Habanero Sauce and it is Awesome. I love adding it onto my sandwiches to kick it up. Pour it on my stick cheese. I crave the heat! Love the Newsletters.

  4. 5 stars
    I typically ferment, and don’t like vinegar bases, but I just didn’t have the time so I tried this recipe. I had just harvested a batch of Big Jim peppers and since they’re about the same decided to try instead of fresnos. Amazing! Possibly the best hot sauce ive ever made! Sauteeing until charred is an inspired idea, and it came out great!

  5. I Love Fresnos, especially for the lovely color and moderate heat they contribute. I make a hot sauce at home with Fresnos, habaneros, and sometimes, Carolina Reapers, plus a big dose of pineapple for sweetness. I call it “Aloha”. I haven’t grown any Fresnos yet, I buy them at the supermarket, but I grow the other varieties. I’m going to try germinating them this winter as I haven’t seen any seedlings in my local garden shops.
