Easy Sweet Chili Sauce Recipe

I bottled a perfectly balanced sweet, tangy and spicy chili sauce that makes fried, grilled, and roasted favorites sing while leaving store-bought jars in the dust.

I adore this sweet chili sauce because it hits every note I want in a dip: sticky sweet, tangy, and teasingly spicy. I love the bright snap that rice vinegar brings and the punch of garlic that cuts through the sugar without apologizing.

It clings to fried shrimp, pools perfectly with spring rolls, and wakes up dull takeout leftovers. But it’s more than condiment status for me; it’s the sauce I reach for when I need bold flavor with zero fuss.

Heat that lingers. Sweetness that sings.

Pure, unapologetic craveability. I’m obsessed with it, truly, and I hoard jars often.

Ingredients

• Sugar: sweet backbone, gives glossy stickiness and balances heat.
• Water: thins the mix so it’s saucy, not syrupy.
• Rice vinegar: bright tang, cuts sweetness and keeps it lively.
• Basically: skip any premade base; you’ll make it fresher yourself.
• Garlic: sharp, warm bite that makes the sauce taste homemade.
• Chiles: heat control—mild flakes or fiery Thai chiles, up to you.
• Fish sauce: umami saltiness; soy swaps in for a vegetarian option.
• Plus lime juice: bright pop of citrus if you want extra tang.
• Kosher salt: simple seasoning, pulls all flavors together.
• Cornstarch slurry: thickens the sauce so it clings to everything.

Ingredient Quantities

• 1 cup granulated sugar
• 1/2 cup water
• 1/4 cup rice vinegar
• 2 tablespoons sweet chili sauce base not needed just kidding you dont need that
• 2 garlic cloves, minced
• 1 to 2 teaspoons crushed red pepper flakes or 2 small Thai red chiles, finely chopped (adjust heat)
• 1 tablespoon fish sauce or 1 1/2 tablespoons light soy sauce for vegetarian option
• 1 tablespoon lime juice (optional, for extra tang)
• 1 teaspoon kosher salt
• 1 tablespoon cornstarch mixed with 2 tablespoons cold water (slurry)

How to Make this

1. In a small saucepan combine 1 cup granulated sugar and 1/2 cup water; heat over medium and stir until the sugar fully dissolves and you have a clear syrup.

2. Add 1/4 cup rice vinegar, 1 tablespoon fish sauce (or 1 1/2 tablespoons light soy sauce for vegetarian), 2 minced garlic cloves, 1 teaspoon kosher salt, and 1 to 2 teaspoons crushed red pepper flakes or finely chopped Thai chiles; stir to combine.

3. Bring the mixture to a gentle simmer, not a roaring boil, so the flavors meld and the alcohol in the fish sauce softens; simmer for about 3 minutes.

4. Taste now and decide if you want extra tang; add 1 tablespoon lime juice if you do, but dont add it too early or the lime will fade.

5. Mix 1 tablespoon cornstarch with 2 tablespoons cold water in a small bowl to make a smooth slurry with no lumps.

6. Slowly whisk the slurry into the simmering sauce, stirring constantly so it doesnt clump; the sauce will thicken quickly in 30 to 60 seconds.

7. Cook for another 1 minute after thickening to cook out the starchy taste, then remove from heat; the sauce will set up a bit more as it cools.

8. If you want a smoother texture, blitz briefly with an immersion blender or pass through a fine sieve to remove chile seeds and garlic bits; if you like it chunkier, leave it as is.

9. Let cool to room temp, then transfer to a clean jar and refrigerate. It keeps well for up to 2 weeks. Reheat gently before using if it becomes too thick in the fridge.

10. Tip: adjust heat by using less flakes or removing seeds from chiles, and for extra depth add a splash of soy or a teaspoon of toasted sesame oil right at the end.

Pro Tips

1. Make the sugar syrup first and taste it before you add anything strong. If it tastes too sweet, add a splash more vinegar or a squeeze of lime at the end. Dont add the lime early or it will get flat.

2. If youre worried about fish sauce being too funky, start with half and add more in small amounts. Soy sauce will make it saltier but less complex, so balance with a touch more acid or a tiny bit of extra sugar.

3. Whisk the cornstarch slurry well so there are no lumps and pour it in slowly while stirring constantly. The sauce thickens fast, so stop adding slurry once it looks slightly looser than you want—it’ll set up as it cools.

4. For a smoother, jar-ready sauce remove seeds and bigger garlic bits before you chill it, or blitz it briefly with an immersion blender. If you like texture, leave those bits in. Either way store in a clean jar and reheat gently; cold fridge sauce often tightens up too much.
