Homemade Sweet Chili Sauce with Fresh Hot Peppers

Some foods are just need to be dipped. In America, a chicken nugget isn’t happy without a side of ketchup or maybe some sweet honey mustard.

In Thailand, fried or grilled chicken is only complete when dipped in sweet chili sauce, or น้ำจิ้มไก่ (chicken dipping sauce). This sweet and spicy sauce is also perfect for countless other finger foods, from dumplings to spring rolls and more!

In this article, we’ll share our simple recipe for sweet chili sauce using homegrown Thai peppers. The process is quick and easy, and requires minimal equipment and ingredients. Let’s cook!

How to Use Sweet Chili Sauce

I love dipping sauces. Whether it is a splash of hot sauce or a side of thick BBQ sauce, some meals are not complete without a flavorful sauce.

With a properly made sweet chili sauce, a little will go a long way. It is all about the concentration of flavor in this sauce, meaning just a small dip will completely level up your food.

Here are a few basic uses for sweet chili sauce:

  • Fried chicken
  • Grilled shrimp
  • Dumplings
  • Spring rolls
  • Fried rice
  • Wings

The list can go on, but you get the idea. Sweet chili sauce combines all of the important flavor experiences – sweet, salty, spicy, and acidic. This stuff truly is a flavor bomb!

Sweet Chili Sauce Ingredients

For this recipe, we like to keep it really simple. It is designed to improve on other food, not overpower the entire flavor. So, for our sweet chili sauce, we use just 7 ingredients. This could certainly be altered if you want to create something unique to your tastes (maybe some ginger or soy sauce).

Sweet chili sauce ingredients


  • Thai peppers. If you can’t find authentic Thai chilies, well, we recommend growing them! However, you can use any red chili as a substitute, such as cayenne, red jalapeno, serrano, santaka or other spicy peppers. Thai chilies definitely lead to the best flavor!
  • Garlic. Fresh garlic is a must for this recipe. It adds familiar richness and satisfying, complex flavor.
  • Rice vinegar (unseasoned). This is an absolute must! Making this sauce with apple cider vinegar will lead to a completely different flavor. If you have to compromise somewhere in this recipe, don’t let it be here.
  • Water. Water helps even out the flavor and avoid an overly-sweet or salty concentration. Some of the water will boil off, leading to a perfectly runny-yet-sticky consistency.
  • White sugar. You could perhaps use an alternative to refined sugar, but plain white sugar leads to a very pure sweetness. Agave nectar, honey, and even fresh fruits have been suggested as alternatives.
  • Sea salt. Salt makes the flavors pop – if you are using seasoned rice vinegar, reduce or omit the added salt.
  • Corn starch + water. Added towards the end of cooking to thicken the sauce.

Tip: You could thicken this sauce by boiling off the water to create a syrup. However, in our experience, this makes the sauce far too sweet, so corn starch is a better option.

How to Make Sweet Chili Sauce

With all the basic ingredients lined up, all that is left to do is prep and quickly cook the sweet chili sauce.


  • Knife
  • Spoon (for deseeding)
  • Medium sauce pan


  • 5-7 Thai peppers (~2 tbsp), finely chopped
  • 1-2 cloves garlic (~1 tbsp), finely chopped
  • 1/4 cup rice vinegar
  • 1/2 cup water
  • 1/2 cup white sugar
  • 3/4 tsp salt
  • 1/2 tbsp corn starch + 1 tbsp cold water (for thickening)

How to make sweet chili sauce.

  1. Clean and deseed peppers.

    Wash your Thai peppers and dry them. Slice lengthwise and scrape out the seeds with a spoon. The seeds are bitter, so make sure you are left with just the skin and flesh of each pepper.Removing pepper seeds

  2. Finely chop peppers and garlic.

    Finely chop the Thai peppers and garlic cloves. The smaller the pieces, the better, as they will stick better when dipping.Chopping Thai chilies

  3. Add vinegar, water, sugar, peppers, garlic and salt to sauce pan.

    Add all ingredients except the corn starch + cold water slurry to a medium sauce pan. Bring the mixture to a boil and then reduce to a simmer.Sweet chili sauce in pot

  4. Simmer for 4-5 minutes.

    Simmer the mixture for 4-5 minutes on medium-low heat, stirring occasionally.

  5. Mix the corn starch and cold water.

    In a small bowl, add the cold water to the corn starch and mix thoroughly. Adding corn starch to hot water will lead to clumping, which is why it must be mixed separately.

  6. Add corn starch slurry and cook another 3-4 minutes.

    Add the corn starch mixture to the sauce pan and stir to combine. Simmer an additional 3-4 minutes until the bubbles become more concentrated and the mix is slightly thicker. Corn starch added to sweet chili sauce

  7. Remove from heat and cool.

While this sauce is quick and easy to make, it can also go wrong. Here are a few mistakes to avoid making while cooking the sweet chili sauce:

  • Don’t overcook it. If your sauce is cooked at a high temperature, the sauce may become too thick. Avoid boiling off all of the water by keeping the sauce at a low simmer.
  • Don’t add dry corn starch to hot sauce. Dry corn starch will clump when added to hot liquids. It must first be mixed with cold water before going into the hot pan.
  • Keep the seeds out of it. A few seeds are okay, but try to remove the majority. The bitter flavor of the seeds and placenta take away from the flavor, though they do contain the majority of the pepper’s heat.
