Easy Homemade Hot Pepper Hot Sauce

Follow these easy instructions at home to make homemade DIY hot sauce from hot peppers, such as red Fresno peppers and habanero peppers! There's a lot to consider when making your own homemade hot sauce. In this post I'll give you my best basic pH-tested homemade hot sauce recipe, as well as some suggested flavor variations so you can customize it and make it your own!

My homemade hot sauce recipe has enough vinegar in it to have a shelf-stable pH (for home use) but not so much vinegar that it overrides the bright, fresh pepper flavors of the sauce. And if making a pH-stable DIY hot sauce doesn't matter to you, I've included notes below for reducing the amount of vinegar.

Okay, so, historically, hot sauce has not been my thing. I don't love spicy food. I prefer to actually taste my food, not cry through it while chugging glasses of milk to stop the inside of my mouth from blistering. So when my husband decided he was going to start making hot sauce from scratch, I was interested in the process, but bummed that I wouldn't reap any of the rewards.

But this homemade hot sauce? This hot sauce I actually like. And not just because I can control just how spicy it is. I love it because it's all about that gorgeous, fresh hot pepper flavor, not so much about burning your face off.

So I asked him if I could share his hot sauce recipe, and today's your lucky day! He's given me all his best homemade hot sauce tips, tricks, and advice. Let's dive in.

Why I Like Making My Own Hot Sauce

The first reason I like to make homemade hot sauce from peppers is being able to properly balance the acidity. Acidity is essential to a hot sauce. It’s what makes hot sauces “zing.” You know that feeling you get in the corners of your mouth when you suck on sour candy? That’s acidity. That’s the zing.

When the acidity in a hot sauce is well-balanced, it adds to the overall flavor. When it's not balanced, the acidity of the vinegar overpowers the flavor of the sauce. It shows up as a separate, wholly unpleasant burning sensation rather than a flavor-booster.

The second reason I like to make my own hot sauce is freshness. Bottled hot sauces are often exposed to light and can be on shelves for weeks, if not months... and who knows how long they’ve been sitting in storage before that. Time and light exposure are the death of flavor.

Homemade hot sauce made from fresh peppers, however, tastes nothing like a store-bought hot sauce. Once you’ve had fresh homemade hot sauce, it’s really hard to want to go back to store-bought (though my husband does still make an exception for Cholula, because "that hot sauce was created by the gods").

Ingredient Notes - Pick Your Peppers Wisely!

Here are the ingredients you'll need to make my basic DIY hot sauce. Fresno peppers can be hard to find depending on the season, but everything else should be readily available at most grocery stores. And you can always sub in other pepper varieties instead of Fresnos (I've recommended some below). See recipe card at the end for ingredient quantities.

Fresno peppers are my favorite pepper to use as the base of my homemade hot sauce. You can use all Fresno peppers, all cayenne peppers, all habanero peppers, or you can use a blend of red peppers to create a hot sauce with a more complex flavor and range of heat levels.

The spicier the pepper and the more of it you use, the spicier your hot sauce will be. I like the slightly fruity, sweet flavor of Fresno peppers (2,500–10,000 Scoville) but often add in a few scotch bonnets or habaneros (each 100,000-350,000 Scoville), and/or a red bell pepper to balance out that heat. It's really up to you!

You can even use green peppers like poblanos, serranos, or jalapeños. Just don't mix too many red and green peppers in one batch or you'll end up with a muddy brown hot sauce.

When it comes to choosing a vinegar, I usually go for plain white distilled vinegar because it lets the flavor of the peppers really shine. You can use different vinegars depending on what kind of flavor you're looking for. For a sweeter, fruitier hot sauce, use apple cider vinegar. For a citrusy hot sauce, use lemon juice and white wine vinegar.

Other flavors to consider adding: You want to add some fruit? Throw some pineapple chunks, peaches, orange peels, etc. into it. You want to add a splash of tequila to give it a slight burn? Go for it. You want to add pickle juice? My husband thinks that's disgusting (he hates pickles) but encourages you to follow your heart.

How I Make Homemade Hot Sauce

First things first, put on a pair of disposable kitchen gloves. If you don’t wear gloves when chopping peppers, you will get pepper oils (aka capsaicin) in all your finger joints and wrinkles and fingernails. And you will regret it as soon as you go to rub your eyes or, worse, go to the bathroom.

So once you've got your gloves on, chop up and weigh the peppers. Use a kitchen scale to weigh the chopped peppers in a large bowl.

I find I get the best, smoothest, and fastest results using a high-powered blender like a Vitamix (I use the Vitamix 5200). If you have a less powerful blender, you may need to run it longer for a smooth sauce.

You can even strain the hot sauce right into the bottle you plan on storing it in. Arrange the strainer inside a funnel and press the hot sauce through the strainer into the funnel. You'll likely have to do this in batches, depending on the size of your strainer and funnel.

Storing Homemade Hot Sauce in Bottles

Whether you're bottling your homemade hot sauce for home use or to give as gifts, you always want to store it in a clean, sanitized bottle.

Completely submerge and boil your bottles to sterilize them, and fill them while they — and the hot sauce — are still hot. For more on this and the specific times and temperatures required for proper food safe hot sauce bottling, check out Spicy Trio's How to Bottle Hot Sauce Guide.

You can buy glass hot sauce bottles online in sets that come with lids, labels, and those plastic caps (called "orifice reducers" lol) that go over the mouth of the bottle to slow how quickly the hot sauce comes out.

We go through hot sauce so quickly around here that we usually store ours in a clean plastic squeeze bottle in the fridge. Squeezing a perfect zig-zag of hot sauce onto your eggs in the morning really makes you feel like a pro! And you just can't get that experience with a glass bottle.

Does hot sauce go bad? How long does hot sauce last? Eventually, yes, hot sauce will go bad! This hot sauce has a shelf stable pH which means it can be safely stored at room temperature away from direct sunlight for several months (I'd estimate 6-8 months, though we always finish ours well before then!). Its shelf life will be extended if you keep it in the fridge. After that time, it's not that it necessarily "goes bad" but you might notice the flavors starting to deteriorate after that. If you're planning on storing your hot sauce for months, I do recommend using a glass bottle.

And while this homemade hot sauce does have a shelf stable pH for home use and can be safely stored at room temperature, it also can't hurt to store it in the fridge just in case. That's what I do.

Practical Tips & Recipe Notes

• Taste whatever peppers you're using before making your hot sauce so you have some sense of their flavor and level of heat. Sometimes even peppers you're familiar with can surprise you! A few years ago we grew jalapeños in our Aerogarden and learned the hard way that peppers grown in a hydroponic garden are (approximately) a thousand times hotter than grocery store jalapeños. (That batch of peppers also was what taught Jimmy to always wear latex gloves when chopping peppers, btw.)
• HAVE I MENTIONED ENOUGH YET TO WEAR KITCHEN GLOVES WHILE HANDLING HOT PEPPERS? HEED THIS WARNING, PLEASE, I BEG YOU.
• If you don't have a blender, a powerful food processor can probably get the job done, though I haven't personally tried it. You'll want to pause to scrape down the sides of the bowl several times and will probably have to let it run for a longer time.
• If you don't care about a shelf-stable pH, you can reduce the vinegar in this hot sauce to as little as 4 ounces (½ cup).
