Sharing is caring!

For the past few years, my pepper plant has been going crazy! Last year I dried the peppers and we ate them with Mexican food. This year I wanted to try making something different. I roasted the peppers, along with a large head of garlic, and onion to make this Homemade Chili Sauce.

I was surprised not only how easy it was to make, but how delicious it turned out. In fact, I liked it enough to share it with you!

How to Make Chili Sauce

Who doesn’t love some good homemade Spicy Chili Sauce, right? The men in my family are hot sauce connoisseurs! My husband, Scott, and my son, Scotty, use chili sauce on everything!

After looking into the process of making hot sauce, I was amazed at how simple it was. Since nothing beats homemade, I thought I’d give it a try.

As you might know, the main ingredient in hot sauce is chilis. They obviously add the spiciness needed. Vinegar is also required to act as a preservative. Additionally, if using very hot chilis, you may need to add tomatoes, tomatillos, or carrots to balance out the heat. Finally, garlic, onions, and spices can be used to perfect the flavor of the sauce.

Spicy red chili sauce made with homegrown Serrano peppers.

Course: Appetizers, Side Dish, Snacks
Cuisine: Mexican
Servings: 2 16 oz. jars
Calories: 15 kcal
  • 1 lb. red serrano peppers
  • 1/2 medium white onion chopped in fourths
  • 1 bulb garlic
  • 2 T. olive oil
  • 1 T. salt
  • 1 medium lime
  • 3 T. vinegar
  1. Rinse and dry one pound of serrano peppers and add to a foil-lined cookie sheet. Slice the tip off of a bulb of garlic and place on the tray. Arrange the chopped onion on the tray and pour the olive oil over everything on the tray, making sure to pour some over the exposed ends of the cloves of garlic. Sprinkle with half of the salt.
  2. Place the tray in the oven and broil on low until everything is starting to char. Check frequently to avoid burning. I pull the tray out every few minutes, removing the peppers that are charred and placing the tray back in the oven until the onion and garlic are also charred.
  3. Add the peppers and onion along with the remaining salt in a blender or food processor. Squeeze the garlic cloves out of the bulb and add to the blender. Add one to two cups of water and blend until you reach the desired consistency.
  4. Mix in the juice of one lime and the vinegar.
  5. Pour the sauce into the jars and store in the refrigerator until cool enough to enjoy. Serve with chips or your favorite Mexican meal.
