Key Ingredient Roles for Taco Bell Fire Sauce
Why so much spicy stuff? That’s the fun part! Each of these ingredients adds something to the flavor of Taco Bell Fire Sauce!
Fun fact: The spicy flavor of ingredients like cayenne pepper and cumin comes from a substance called capsaicin. This substance is actually a mild toxin that can irritate sensitive tissues. This causes the slightly painful “hot” or “spicy” sensation in your mouth when you eat spicy food.
Capsaicin is also why you want to wear rubber gloves and avoid touching your face or eyes when working with spicy peppers. If you get some capsaicin in your eyes, rinse them out with water. Believe me, it hurts when even a little capsaicin gets into your eyes!
Tomato Paste
6 ounces tomato paste
When combined with water, tomato paste forms the tomato-flavored base of your Fire Sauce.
Water
3 cups water
Water basically thins out the tomato paste, making it more “sauce-like.” Some of it might steam away while you’re mixing the sauce up and heating it. That’s normal.
Cayenne Pepper
2 teaspoons cayenne pepper
Cayenne pepper is a mainstay in spicy sauces for its ability to bring the heat.
Chili Powder
1 1/2 teaspoon chili powder
“Regular” chili powder is less potent than cayenne pepper or cumin, but it can still bring a bit of heat. Depending on which type of chili powder you use, it can also add a slightly sweet or smoky flavor to the sauce.
Here’s a quick look at the most common types of chili powder and how they compare to other common spicy powders, if you’d like to get more advanced when using chili powder.
| Chili Powder Type | Flavor Profile | Heat Level in Scoville Units (SHU) | Common Uses |
|---|---|---|---|
| Regular Chili Powder | Mild, earthy, and smoky | 2-4 SHU | Chili, tacos, and sauces |
| Cayenne Pepper | Sharp and spicy | 30,000-50,000 SHU | Spice blends, salsas, hot sauces |
| Chipotle Powder | Smoky, deep, and spicy | 2,500-8,000 SHU | Barbecue sauces, marinades |
| Ancho Powder | Sweet, fruity, and mild | 1,000-2,000 SHU | Mole sauce, stews, enchiladas |
| Pasilla Powder | Rich and slightly sweet | 1,000-2,000 SHU | Salsas, soups, and sauces |
| New Mexico Chili Powder | Slightly sweet and earthy | 1,000-3,000 SHU | Chili, enchiladas, carne adovada |
| Serrano Powder | Bright and fresh | 5,000-15,000 SHU | Salsas, sauces, as a condiment |
What are Scoville units? Scoville units (SHU) are the standard measurement of “spiciness level” in many spicy foods, especially hot peppers. The Guinness Book of World Records officially recognized Pepper X as the world’s spiciest pepper with 2,693,000 SHU. For reference, jalapeno peppers typically have 3,000 to 8,000 SHUs.
As you can see in the video below, trying a “Pepper X” takes courage!
Salt
2 1/2 teaspoons salt
Salt helps balance the spice in this fire sauce. It also acts as a preservative, preventing the tomato paste from going bad.
Hot Sauce
1 tablespoon hot sauce
Hot sauce can really ramp up the heat in this recipe. Of course, you can add more or less hot sauce depending on how spicy you like your Taco Bell Fire Sauce. Frank’s RedHot is my favorite hot sauce brand, though of course, there are plenty of hot sauce brands to experiment with if you prefer a hotter or milder hot sauce.
You may even want to try this homemade buffalo sauce for some extra tang.
White Vinegar
2 teaspoons white vinegar
White vinegar provides a mild acidic flavor that helps cut the spice.
Onion Powder
1 teaspoon onion powder
While barely noticeable if you get this Fire Sauce spicy enough, onion powder can add a bit of complexity to the flavor. It also pairs well with savory or spicy foods.
Ground Cumin
1 teaspoon ground cumin
Ground cumin adds a little more spice to this Fire Sauce.
Garlic Powder
1 teaspoon garlic powder
Garlic powder also adds a little more complex flavor.
Cornstarch
1/2 teaspoon cornstarch
Cornstarch acts as a thickener for this sauce.

Method for Making Taco Bell Fire Sauce
You don’t need anything fancy to make this copycat Taco Bell Fire Sauce at home. Just combine the ingredients, heat everything together, and let the flavors meld into that familiar spicy kick.
Step One: Mix Water and Tomato Paste
Mix water and tomato paste in a medium saucepan until it’s evenly mixed.
Step Two: Add Spices and Cornstarch
Add cayenne pepper, chili powder, salt, hot sauce, white vinegar, onion powder, ground cumin, garlic powder, and cornstarch to the saucepan. Mix thoroughly to ensure all ingredients are well incorporated.
Step Three: Heat the Sauce
Turn the burner to medium heat and heat the sauce for 3 minutes. Stir continuously until the sauce is smooth and heated through. A little steam will be normal, but try not to let it bubble too much.
Step Four: Let the Sauce Cool
Remove the saucepan from the heat and let the fire sauce cool down.
Step Five: Refrigerate the Sauce
Transfer the cooled sauce into a container with a tight-sealing lid. A mason jar should work. Refrigerate for at least an hour to allow the flavors to meld.
Step Six: Taste and Adjust Hot Sauce Amount
Give it a quick taste to see if it’s spicy enough. Have a piece of bread handy in case you already poured a lot of hot sauce in and got it closer to the “Diablo” level.
The bread does a good job of absorbing the spice if you need it. If you think it needs more hot sauce, gradually stir some in until it’s the right level of spice.
Step Seven: Serve with Your Favorite Savory or Spicy Dishes
Taco Bell Fire Sauce goes well with many Mexican or Asian dishes. Not that there’s anything wrong with putting it on other savory or spicy dishes. I’ve caught my sister slipping spicy sauce into her favorite macaroni and cheese before!

Ingredient Substitutions for Taco Bell Fire Sauce
For most sauces, you just need a good thickener. If you’re out of cornstarch, many ingredients that have “starch” in the label, like potato starch or tapioca starch, should work. Arrowroot powder will also work if you have any.
If you’re out of white vinegar, apple cider vinegar should work, although it has a slightly stronger flavor.
Most hot sauce brands comparable to Frank’s RedHot should work. Of course, you can add as much or as little as you like. That’s the neat part about Taco Bell’s hot sauce. You can get them as hot or as mild as you like.
If you’re on a low-salt diet, you could cut the salt in this by up to half.
The main thing to remember about imitation Taco Bell Fire Sauce is that it’s not very finicky. You can experiment to get it exactly the way you like it.
FAQ for This Imitation Taco Bell Fire Sauce Recipe
Making this sauce sounds simple, right? We do sometimes get questions about it. With these FAQs, I tried to answer some of the most commonly asked ones. If you think of one we haven’t thought of yet, feel free to ask in the comments section.
Why is my Fire sauce too thick or too thin?
This is actually the most common issue with making any sauce! The most common culprits are too much cornstarch or too little water. Leaving it on the heat for too long can also cause too much of the water to evaporate. If your sauce is too thick, gradually stir in some water until it’s the right consistency.
If the sauce is too thin, too much water or too little cornstarch might have been added. Try mixing in a little more cornstarch to reach the right consistency.
What makes Fire Sauce different from Taco Bell Hot Sauce?
The spice level is the main difference. Taco Bell Fire Sauce is a little bolder and spicier than Taco Bell Hot Sauce. It’s not quite as spicy as Diablo Sauce, though.
How long does homemade Taco Bell Fire Sauce last in the fridge?
When stored in a sealed container like a mason jar, Taco Bell Fire Sauce can last up to a week in the refrigerator.
What are the best things to put the Taco Bell Fire Sauce on?
Putting this sauce on Mexican food is the obvious choice. It also goes well on hamburgers, hot dogs, macaroni and cheese, and even pizza if you like slightly spicy pizza!
