Lively Sweet Chili Sauce

As seen in Small Bites, Big Flavors.

Whip up this lively sweet chili sauce for a punch of sweetness and a kick from bird’s eye chili and bell pepper. Garlic and onions deepen the taste, while vinegar brings a fresh buzz. Starch thickens it up, making a shiny, scoopable sauce for fries, egg rolls, grilled chicken, or veggies. It’s super simple and hangs out in your fridge for whenever you need it. Add pep to your favorites—dunk, dip, or drizzle as you please.

Sweet chili sauce you make yourself hits all the good spots. You've got a bit of sweetness, a light tang, and just enough heat. Dip spring rolls or grilled chicken in it and you'll want to say goodbye to the ones from the store. I love it because I can toss in whatever I want and know exactly what I'm eating. Seriously, once I made it, I never went back. Fast, super fresh, nothing fake, just real taste.

My daughter and I first whipped this up standing next to each other at the stove. We kept sneaking spoonfuls as it cooked. It just took us right back to those summertime barbecues, only now everything tasted a whole lot brighter and fresher.

Bright Ingredients

  • Potato starch or cornstarch: This makes the sauce thick and shiny. If you can, go with potato starch for a silkier feel.
  • Sugar: Adds sweetness and helps keep it fresh. Plain white sugar gets you the cleanest taste.
  • Salt: Rounds out all the flavors. Fine sea salt mixes in really easily.
  • Vinegar: That's what gives it smack and tang. Pick a clear type like distilled or cane vinegar for the boldest zing.
  • Water: Makes it all blend and simmer nicely. If you've got it, filtered is great.
  • Garlic: The backbone of big, savory flavor. Fresh garlic cloves are best.
  • Yellow onion: Brings some rich, mellow depth. Heavier onions are usually juicier.
  • Bird’s eye chili or chili flakes: Packs the heat. Plumper chilies make things spicier, or use flakes for something softer.
  • Red bell pepper: Pick one that's totally ripe and bright red for extra sweetness and gorgeous color. Avoid the ones that seem dull or unripe.

Simple How-Tos

Cool and Store:
Let your sauce chill at room temp. Spoon it into a super clean jar, pop the lid on tight, and stash it in the fridge. Tastes even better the next day and keeps for about a month.
Thicken Safely:
Stir your starch with a couple spoonfuls of water so you don't get any lumps. Drizzle that goo into your bubbling pot, stirring as you go. Let it simmer just till it gets thick and glossy, then cut the heat—it'll get even thicker as it cools down.
Simmer Gently:
Move your blended mix to a pot. Toss in sugar, salt, and vinegar. Give it a stir. Bring it up to a bubbling simmer over medium, just until everything dissolves and blends together. Then drop the heat a notch.
Pulse it Together:
Take the bell pepper, chilies, onion, garlic, plus water, and toss them all into a blender or food processor. Pulse until it's fine but still a bit chunky—little pieces give your sauce that awesome texture.
Chop the Veggies:
Cut off the bell pepper stems and scoop out the seeds along with the chilies. Chop onion and garlic well. Slice fresh chilies as thinly as you can for easy blending.

I always get excited for the part where you toss in the fresh garlic. It's that moment when your whole kitchen smells sweet and spicy. Feels just like making late-night movie snacks for the whole crew.

How to Keep It Fresh

Pop your homemade chili sauce in a tight glass jar and set it in the fridge. It'll taste and pour great for about four weeks. Want to make a batch? Freeze it in ice cube trays if you need. Just thaw a cube whenever you need a quick hit of flavor.

Swap It Up

Can't find fresh bird’s eye chilies? Just toss in chili flakes instead. For less heat, use only bell peppers and skip anything spicy. If you're out of potato starch, cornstarch does a pretty similar job—use just a bit extra if you want it thick.

How to Enjoy

This sauce is awesome with everything from crunchy egg rolls or fried dumplings, to grilled chicken or simple roasted veggies. I like slathering it on thick tofu slices before broiling, or drizzling it over my morning eggs—makes breakfast way more exciting.

Backstory

This spicy-sweet sauce shows up on kitchen tables all over Southeast Asia. It's famous for waking up your taste buds super fast. Doing it from scratch means you get to tweak how much chili or sugar goes in. Plus, it keeps you close to those old-school Thai flavors.

Steps to Follow

Step 01

Spoon it over grilled meats, roasted veggies, or anything you love as a tasty dip or zesty topper.

Step 02

Take the pan off the heat and let the mixture chill out—don’t worry, it'll keep thickening as it sits. Pour it into a clean jar, close it tightly, and pop it in the fridge. It’ll last about a month.

Step 03

Mix the potato or corn starch with 2 tablespoons water in a small cup. Stir that into your simmering sauce and keep mixing. Let it bubble gently until you like the texture.

Step 05

Put the chopped garlic, onion, bell pepper, and chilies in your food processor with 2 cups water. Pulse so it’s chunky, not totally smooth.

Step 06

Chop up the garlic, red bell pepper, onions, and then trim the chilies if needed.

Additional Tips

  1. Don’t go overboard with blending. Little veggie bits look nice and spread out the flavor.
  2. If you want less spice, throw in fewer chilies or just stick with the bell pepper.
