5-Ingredient Classic Sweet Chili Sauce
A glossy, tangy-sweet sauce with a gentle chili warmth, made from just 5 main ingredients (plus water and salt). This homemade version beats bottled every time, mostly because you control the heat and the balance.
It’s ready in about 15 minutes and works as a dip, a glaze, or a drizzle on anything that needs a sticky, sweet kick. Once you know how easy it is, you’ll keep a jar in the fridge on purpose.
What Makes This Sweet Chili Sauce So Good
Store-bought sweet chili sauce often leans too sweet or tastes flat. This one is balanced: the vinegar cuts through the sugar, the garlic adds a savory backbone, and the chili flakes bring slow warmth rather than sharp heat.
It clings to whatever you dunk in it, glossy and just thick enough. Because you control the chili, you can make it mild for kids or fiery enough to make your nose run.
Ingredients
- 1/2 cup granulated sugar: white sugar dissolves cleanly and lets the chili flavor shine.
- 1/3 cup rice vinegar: unseasoned is best, white vinegar works in a pinch.
- 1/4 cup water: helps everything dissolve without scorching.
- 2 cloves garlic: minced finely so it disperses evenly.
- 1 to 2 tbsp red chili flakes: adjust for your preferred heat level.
- 1/4 tsp fine salt: just enough to round out the sweetness.
- 1 tbsp cornstarch mixed with 1 tbsp cold water: the slurry that gives the sauce its cling.
Variations / Substitutions
- Make it spicier: swap half the chili flakes for crushed bird’s eye chili or add a squirt of sriracha.
- Change the acid: rice vinegar is mild, but lime juice or apple cider vinegar bring their own character.
- Alternative sweetener: honey or coconut sugar work, though the flavor shifts toward caramel or floral notes.
- Add depth: stir in 1 tsp fish sauce or a pinch of ground ginger for a savory twist.

How to Make Classic Sweet Chili Sauce
Step 1: Mix the Sauce Base
Place a small saucepan over medium heat. Add the 1/2 cup sugar, 1/3 cup rice vinegar, 1/4 cup water, minced garlic, 1 to 2 tbsp chili flakes, and 1/4 tsp salt. Stir with a spoon or whisk until the sugar mostly dissolves, about 2 minutes, and the garlic turns fragrant.
Step 2: Thicken the Sauce
Give the cornstarch and water slurry a quick stir to recombine, then pour it into the saucepan while whisking. Keep stirring as the mixture comes back to a gentle simmer. Cook for 2 to 3 minutes, just until the sauce visibly thickens and turns from cloudy to translucent and glossy. Remove the pan from the heat the moment it coats the back of a spoon.
Step 3: Cool and Serve
Let the sauce cool right in the pan for a few minutes, then pour it into a clean jar or bowl. It will thicken a little more as it cools. Serve at room temperature alongside spring rolls, drizzle over grilled chicken, or refrigerate for later.
Tips for the Best Sweet Chili Sauce
- Always mix the cornstarch with cold water before adding it. That prevents lumps even if the pan is hot.
- Taste the sauce before you add the slurry. The heat level comes from the chili flakes steeping in the liquid, so now is the moment to add more if you want it spicier.
- If the cooled sauce ends up thicker than you like, stir in a teaspoon of warm water to loosen it.
Easily scale this sauce for parties or meal prep:
| Yield | Sugar | Vinegar | Water | Garlic | Chili Flakes | Cornstarch Slurry |
|---|---|---|---|---|---|---|
| 1 cup | 1/2 cup | 1/3 cup | 1/4 cup | 2 cloves | 1–2 tbsp | 1 tbsp + 1 tbsp |
| 2 cups | 1 cup | 2/3 cup | 1/2 cup | 4 cloves | 2–4 tbsp | 2 tbsp + 2 tbsp |
| 3 cups | 1 1/2 cups | 1 cup | 3/4 cup | 6 cloves | 3–6 tbsp | 3 tbsp + 3 tbsp |
Storing Leftover Sweet Chili Sauce
- Refrigerate: pour the cooled sauce into a jar with a tight lid. It keeps well for up to 2 weeks. Give it a stir before using because the chili flakes can settle.
What to Serve With Sweet Chili Sauce
It works as a dip for fresh spring rolls because the bright vinegar cuts through the herbs and noodles. Drizzle it over grilled chicken skewers for a sticky glaze, or toss a spoonful with stir-fried vegetables right before serving to coat everything in a sweet, spicy finish.
Frequently Asked Questions
Can I use fresh chili instead of flakes?
Yes. Finely mince 2 or 3 red bird’s eye chilies and sauté them with the garlic to soften their raw edge before adding the liquids.
How do I make it spicier without changing the texture?
Add more chili flakes or stir in a little sambal oelek after the sauce has thickened but while it’s still warm.
My sauce didn’t thicken. What went wrong?
It likely didn’t simmer long enough after adding the slurry, or the slurry wasn’t mixed cold. Return it to a low boil for another minute and it should set up.
Is this sauce gluten-free?
Yes, as long as you use pure cornstarch and check that your vinegar is gluten-free (rice vinegar and distilled white vinegar typically are).
