I once opened my refrigerator and saw many half used bottles of condiments in the fridge—maybe five, ten, or even twenty. That moment pushed me to make sauce instead of buying bottle again, so I tried sweet chili sauce, also thai sweet chili sauce, a delicious condiment with a balance of sweet, sour, and spicy, similar to classic sweet and sour sauce but with a spicy kick that easily improves simple dishes.
While learning to make sweet chili sauce from scratch, I realized the recipe is incredibly easy. With simple ingredients, usually less than ten ingredients cooked in one pot, it forms a glossy sticky sauce with sweet savory spicy flavors and savory umami from soy sauce.
Sweet Chili Sauce Recipe Easy-The Short Answer
The recipe originated thailand, called nam jim gai or nam chim kai, now popular worldwide. Chili peppers, garlic, vinegar, and sugar, then thickened cornstarch, give punchy flavors and a vibrant red orange color.
Through scratch cooking, I can control ingredients and adjust heat using heat control and three spice levels to customize the flavor balance for family tastes. This easy sweet chili sauce stays naturally gluten free and dairy free, and you can substitute refined sugar with raw honey or unfiltered honey.
In about five minutes, this delicious recipe turns into a sweet savory sauce and dipping sauce for egg rolls, spring rolls, and dumplings. I use it with chicken wings, fried foods, fried calamari, seafood like shrimp and salmon, tofu, vegetables, and roasted chicken breasts, or as a glaze for main dishes and stir fry—brushed, served side, or tossed for extra flavor and punch, making it a fridge staple for almost everything and better than store bought across a variety dishes.
Ingredients
From my homemade kitchen routine, this Sweet and spicy chili sauce (Sauce) starts with a simple base. I mix ¼ cup water (sometimes cold water) with ¼ cup rice vinegar or white vinegar to get that tangy, sour zing. Then I add 2/3 cup sugar—either granulated or cane—to reach the perfect balance of sweet and spicy flavors.
Heat and flavor boosters I usually add:
- 1–3 Tablespoons chili paste, often Sambal oelek, though sriracha works when substituting
- Fresh chili, garlic, or Garlic cloves for strong umami flavor that amps the savory sauce
- 1 teaspoon red pepper flakes plus other seasonings
- Heat control by heat level: 1 tablespoon = mild, 2 tablespoons = medium, 3 tablespoons = very hot
- A splash of soy, Soy, tamari, or Tamari, which adds a burst of umami and works for gluten free or Gluten Free cooking
For thickening and texture:
- Mix 1 Tablespoon cornstarch (Cornstarch) with 2 teaspoons water while the sauce cooks
- This thickening agent activates the starch and helps the sauce thicken into a light glossy consistency
- If avoiding corn products, simply substitute arrowroot starch as another thickening option
- I keep my phone in Cook Mode to prevent the screen going dark while measuring Tbsp, tablespoon, tablespoons, teaspoon, or teaspoons
For extra texture, I sometimes mix finely grated carrot, shredded carrots, or a peeled finely grated turnip. These vegetables bring natural sweetness, extra punch, and deeper flavors. Once everything is combined, the sauce becomes a reliable go-to recipe, though these additions stay optional.
Step By Step Instructions
I usually start this easy sweet chili sauce in a small sauce pot or medium saucepan over medium heat.
- Combine ¼ cup rice vinegar or white vinegar, 2/3 cup sugar, and ¼ cup water in the pot.
- Stir while heating until the sugar granules dissolve and the mixture becomes clear.
- Add 1–3 Tablespoons sambal oelek (or sriracha)—a popular brand many stores sell made from red chiles—creating the base chili sauce that gives sweet chili sauce its simple, versatile kick.
For thickening:
- In a small bowl, whisk 1 Tablespoon cornstarch with 1 Tablespoon water to make a smooth slurry without lumps.
- Pour it into the sauce pot and stir continuously over medium heat.
- The sauce begins boiling or reaches a gentle simmer; it may look cloudy and white at first, but the cornstarch thickens the sauce until it turns clear and slightly glossy.
For flavor and finishing:
- I sometimes add a splash of soy, tamari, Soy, or Tamari while it’s boiling for extra depth.
- Sprinkle 1 teaspoon red pepper flakes if I want more heat.
- Once the mixture fully dissolves and thickens, remove from heat and transfer the sauce to a bowl or container to cool to room temperature. From my experience, letting it rest a few minutes improves the texture.
Serving and storage:
- Serve with egg rolls, Asian inspired dishes, or sweet chili chicken.
- It also works as a marinade or mixed with mayo for a burger topping.
- Store leftovers in a covered container or pint canning jars in the fridge.
- It keeps about a week, sometimes 6–9 months, so you can store later and use it whenever needed.
Notes
Storage and Make-Ahead Tips
- I often make-ahead this sweet chili sauce because when it sits for 3 days ahead of time, the flavor becomes more flavorful and gives a great start for quick meals.
- Let the sauce cool to room temperature, then pour it into an airtight container and keep it in the refrigerator for 1 week or for months in the freezer.
- When ready to use, thaw it overnight in the fridge before reheating and serving.
- To reheat, place the sauce in a small pot and warm it on low to medium heat until warm. It can also be served chilled or at room temperature.
Getting the Right Texture and Flavor
- While cooking the recipe, the sauce will thicken when you stir the cornstarch slurry.
- The consistency is perfect when it can coat the back of a spoon without immediately dripping, but instead slowly stream and leave a noticeable pattern on the surface of the rest of the sauce.
- You can omit some vegetables such as shredded carrots or turnip. The sauce may become thinner, slightly missing some flavor, but it is still good.
- For a milder version, skip red flakes and let the paste give the necessary heat that stays nearly spicy but balanced.
Flavor Variations and Add-Ins
- If you prefer less sweetness, you can reduce sugar. I’ve tested being able to try reducing it to 1/2 cup for a less sweet result.
- Try extra add-in ideas to build creative flavors, such as a splash of soy or fish sauce for more depth and savoriness.
- For crunch, add 1/4 cup roasted peanuts, sliced scallions, chopped cucumbers, or chives.
- The recipe makes approximately one cup, but you can double the batch if you need to serve a crowd or want to save the extras for later.
Pro Tips
I make sweet chili sauce as a quick and easy shortcut instead of a full from-scratch version. Authentic sauce usually uses fresh red chiles, but they are rarely available at the store, so I check the international foods aisle for sambal oelek near sriracha. Always use rice vinegar because it is mild and slightly tangy; do not substitute it with another vinegar.
If the sauce looks cloudy, it’s normal when cornstarch is added. After stirring the cornstarch slurry, the sauce will clear up, thicken, and reach the right consistency when it coats the back of a spoon and slowly streams instead of dripping.
You can add vegetables like shredded carrots or turnip for more flavor, but omitting them makes a thinner sauce. For a milder version, leave out red chili flakes; the chili paste will still give gentle heat.
You can also reduce sugar to about 1/2 cup for a less sweet taste. For extra flavor, stir in a little soy sauce or fish sauce, or add crunch with roasted peanuts, scallions, cucumbers, or chives. I often double the recipe to make about 1 cup sauce or more so I can serve a crowd and save extras for later.
