Homemade Sweet Chili Sauce
Homemade sweet chili sauce is an easy way to turn homegrown peppers into a sweet, tangy, slightly spicy condiment you can use on all kinds of meals. Made with dried cayenne peppers, garlic, sugar, white wine vinegar, soy sauce, and a little cornstarch, this recipe comes together on the stovetop in about 20 minutes. Best of all, you don’t need a garden to make it, but if you grow your own chiles, this is a delicious way to use some of your harvest!
I’ll be honest: I may have gotten a little carried away planting peppers this year. Not knowing what to expect, I planted nine cayenne pepper plants and nine Thai chile plants. Eighteen pepper plants sounded like a reasonable idea at the time. However, once those plants started producing, I quickly realized that we were going to have a LOT of peppers!
We’ve been freezing them to make hot sauce during the winter, dehydrating them, and using them fresh in just about every way I can think of. We’re even growing enough to make pepper wreaths for gifts. Although I love having homegrown peppers available, finding new ways to use the harvest has become a little project of its own.
That’s where this homemade sweet chili sauce comes in. Instead of letting those dehydrated cayenne peppers sit in a jar waiting for the perfect recipe, I can turn a few of them into a flavorful sauce with ingredients I already have in the pantry. The combination of sugar and vinegar creates that familiar sweet-and-tangy flavor, while garlic and cayenne bring the heat.
Why You’ll Love This Homemade Sweet Chili Sauce
First, this recipe is a great way to use dehydrated peppers. If you’ve ever grown cayenne peppers, you know that a productive plant can leave you with more peppers than you expected. Dehydrating them helps preserve your harvest, and this sweet chili sauce gives you another delicious way to put them to work.
Additionally, homemade sauce lets you control the ingredients. You can make it with dried cayenne peppers, fresh garlic, sugar, vinegar, soy sauce, and cornstarch instead of buying a prepared sauce with a long ingredient list. Since you’re making it yourself, you also know exactly what goes into the batch.
Another reason to love this recipe is how quick it is to make. You’ll toast the peppers and garlic, simmer the sauce ingredients, then thicken everything with a simple cornstarch slurry. There is no complicated equipment or lengthy cooking process required.
Finally, sweet chili sauce is delicious served with homemade egg rolls, crab rangoon, chicken, shrimp, or roasted vegetables. You can also drizzle it over rice bowls or serve it as a dipping sauce for your favorite appetizers. A small batch can add plenty of sweet, spicy flavor to meals throughout the week.
Ingredients for Homemade Sweet Chili Sauce
One of my favorite things about this recipe is that the ingredient list is short. You don’t need a pantry full of specialty items to make a sauce with a great balance of sweetness, tang, and heat.
- Dried cayenne peppers: Use three dried cayenne peppers, or substitute three teaspoons of crushed red pepper. The peppers provide the heat and give the sauce its chile flavor. If you dehydrate peppers from your garden, this is a great opportunity to use them.
- Garlic: Two cloves of minced garlic add a savory flavor that balances the sugar and vinegar. Fresh garlic works especially well because you toast it briefly before adding the liquids.
- Sugar: One cup of sugar creates the sweet flavor that makes this sauce so recognizable. It also balances the sharpness of the vinegar and the heat from the cayenne.
- Water: You’ll need half a cup of water for the sauce, plus another two tablespoons to dissolve the cornstarch.
- White wine vinegar: Half a cup provides the tangy flavor that keeps the sauce from tasting like pure sugar. Its acidity also complements the garlic and peppers.
- Soy sauce: One tablespoon adds savory depth to the sweet and spicy mixture.
- Cornstarch: Three teaspoons thicken the sauce, giving it a consistency that works well for dipping and drizzling.
These simple ingredients come together quickly, so measure everything before you start cooking. In particular, have the cornstarch and its two tablespoons of water ready before the sauce finishes simmering.
How to Use Dehydrated Cayenne Peppers
Dehydrating peppers is a practical way to preserve a garden harvest. Once the peppers are properly dried, you can store them for later use in sauces, soups, stews, spice blends, and other recipes.
For this sweet chili sauce, you’ll chop three dried cayenne peppers before adding them to a warm saucepan. As they toast briefly, their aroma becomes more noticeable. Next, you’ll add the minced garlic and toast it for another minute before introducing the sugar, vinegar, water, and soy sauce.
If you don’t grow cayenne peppers, don’t worry! You can use three teaspoons of crushed red pepper instead. That makes the recipe accessible even if your garden consists of a few pots on the patio—or if you don’t have a garden at all.
Keep in mind that dried peppers can vary in heat depending on the variety and growing conditions. Therefore, if you’re unsure how hot your peppers are, start with a milder amount and adjust the next batch to your liking. Wear gloves when handling hot peppers if you are sensitive to their oils, and avoid touching your eyes or face.
How to Make Sweet Chili Sauce
This homemade sweet chili sauce comes together in a few simple steps. Prepare your ingredients first, and the cooking process will move along quickly.
1. Toast the Dried Peppers
Begin by heating a saucepan over medium heat. Chop the dried peppers and add them to the pan. Toast the peppers for about one minute, stirring as needed so they don’t scorch.
Toasting briefly helps bring out their aroma before you add the other ingredients. However, keep the heat moderate and avoid letting the peppers burn, since scorched peppers can give the finished sauce an unpleasant flavor.
If you’re using crushed red pepper instead of whole dried cayenne peppers, follow the same general approach and watch it carefully.
2. Add the Garlic
Next, add the minced garlic to the saucepan. Continue toasting for another minute, stirring so the garlic warms evenly with the peppers.
Garlic can burn quickly, so don’t leave the pan unattended. Once it smells fragrant, move on to the next step rather than letting it brown too much.
3. Add the Sauce Ingredients
Pour the sugar, half a cup of water, white wine vinegar, and soy sauce into the saucepan. Stir well to combine the ingredients.
At this point, the mixture will look thin, but that’s exactly what you want. The cornstarch will thicken the sauce later, so there is no need to worry about its consistency just yet.
Bring the mixture to a simmer and cook for 10 minutes, stirring occasionally. During this time, the sugar dissolves, and the flavors begin to come together.
4. Make the Cornstarch Slurry
While the sauce simmers, combine the cornstarch with two tablespoons of water in a small bowl. Stir until the cornstarch dissolves and the mixture is smooth.
This mixture is called a slurry. Mixing the cornstarch with cold water first helps prevent dry clumps from forming when you add it to the hot sauce.
5. Thicken the Sweet Chili Sauce
Slowly pour the cornstarch slurry into the simmering saucepan while whisking to combine. Continue simmering for three to four minutes, stirring as the sauce thickens.
Keep an eye on the consistency during this step. The sauce should become thicker and glossy as the cornstarch cooks. Remember that it will thicken a little more as it cools, so you don’t need to cook it until it looks as thick as a refrigerated sauce.
6. Cool and Refrigerate
Remove the saucepan from the heat and allow the sweet chili sauce to cool slightly. Carefully transfer it to a clean glass storage bottle or jar.
Let the sauce cool to room temperature, then refrigerate it. Keep it chilled between uses and use a clean spoon when serving.
This is a refrigerator sauce, not a tested canning recipe. The presence of vinegar does not automatically make a homemade sauce safe for room-temperature storage, so don’t process it for pantry storage using this recipe.
Tips for the Best Homemade Sweet Chili Sauce
A few simple tips can help you get the flavor and consistency you want.
Don’t burn the peppers or garlic. Both ingredients need only a short time in the warm pan. Stir frequently and move on to the next step as soon as they become fragrant.
Measure the cornstarch carefully. Three teaspoons thicken this recipe, but adding too much can make the sauce overly thick or give it a starchy texture. Measure the amount rather than estimating.
Always make a slurry. Mixing the cornstarch with water before adding it to the saucepan helps it blend smoothly into the sauce. If you sprinkle dry cornstarch directly into the hot liquid, it may form lumps that are difficult to remove.
Allow the sauce to cool before judging its thickness. The sauce will continue to thicken as it cools. If it seems slightly thinner than you expected while it’s hot, give it time in the refrigerator before deciding whether the consistency is right.
Adjust the heat carefully. Cayenne peppers vary in spiciness, so your sauce may taste hotter or milder depending on the peppers you use. If you’re making this recipe for the first time with homegrown chiles, you may want to start with a conservative amount.
Label your storage container. Write the name and preparation date on the jar or bottle. This is especially helpful if you make several homemade sauces or preserve lots of garden produce throughout the season.
What to Serve with Sweet Chili Sauce
Once you have homemade sweet chili sauce in the refrigerator, you’ll find plenty of ways to use it. Its sweet, tangy flavor and gentle heat make it a delicious addition to appetizers and main dishes.
Egg Rolls and Spring Rolls
Sweet chili sauce is a classic dipping sauce for egg rolls and spring rolls. The sweetness complements crispy wrappers and savory vegetable or meat fillings, while the vinegar adds a tangy finish.
Serve a small bowl alongside homemade egg rolls for an easy appetizer. You can also offer it with frozen appetizers when you need a quick snack for guests.
Chicken
Use sweet chili sauce as a dipping sauce for crispy chicken tenders, chicken nuggets, or homemade chicken bites. It also tastes great drizzled over grilled chicken when you want a little extra flavor.
For best results, add the sauce after cooking when you want the texture of crispy chicken to remain intact. If you’re using it as a glaze, remember that the sugar can burn over high heat.
Shrimp
Sweet chili sauce makes a delicious dip for cooked shrimp. Serve it chilled alongside a shrimp platter, or drizzle a little over cooked shrimp and rice for a quick meal.
The tangy sweetness complements seafood without requiring a complicated sauce. Add fresh herbs or a squeeze of lime at serving time if you’d like a brighter finish.
Rice Bowls and Roasted Vegetables
You can also drizzle a little sweet chili sauce over rice bowls with chicken, shrimp, or vegetables. The sauce brings sweet and savory flavors to the bowl, while the cayenne adds a little heat.
Roasted cauliflower, carrots, and other vegetables can also benefit from a small drizzle. Start with a little sauce, taste, and add more as needed so it doesn’t overpower the rest of your meal.
Can You Adjust the Spice Level?
Absolutely! The heat depends on the peppers you use, so you can adapt the recipe to your preference.
Cayenne peppers are generally quite hot, while crushed red pepper can vary in intensity depending on the pepper blend. If you prefer a milder sauce, use less pepper in your next batch. For a hotter version, you can experiment with a little more or use different peppers, keeping in mind that the heat may become more noticeable as the sauce sits.
If you’re growing Thai chiles along with cayenne peppers, you might be tempted to use them instead. Thai chiles are quite a bit hotter than cayenne, so start with a small amount if you experiment with a substitution. Make one change at a time and write down what you used so you can repeat the result you like best.
How to Store Homemade Sweet Chili Sauce
After cooking, let the sauce cool slightly before transferring it to a clean glass jar or bottle. Allow it to cool to room temperature, then refrigerate promptly.
Because this recipe has not been tested for shelf-stable preservation, it should not be canned or stored in the pantry. Keep it refrigerated between uses and avoid leaving it at room temperature for extended periods.
Use a clean utensil whenever you take sauce from the container. If you notice an unusual odor, mold, or another sign of spoilage, discard it.
I recommend making a batch you can use while it remains fresh rather than preparing a large quantity for long-term storage. If you want to make a larger batch, scale the ingredients carefully and keep the finished sauce refrigerated.
Frequently Asked Questions
Can I make sweet chili sauce with crushed red pepper?
Yes! The recipe allows you to substitute three teaspoons of crushed red pepper for the three dried cayenne peppers. This is a convenient option if you don’t grow your own chiles or don’t have dehydrated cayenne peppers available.
Why is my sweet chili sauce too thin?
The sauce may need more time to simmer after you add the cornstarch slurry. Cook it for the recommended three to four minutes, stirring as it thickens. Also, remember that the sauce will thicken further as it cools.
Why is my sauce lumpy?
Lumps can develop when cornstarch is added directly to hot liquid without first being dissolved. Mix the cornstarch with the two tablespoons of water until smooth, then whisk the slurry into the simmering sauce.
Can I use fresh cayenne peppers instead of dried peppers?
This recipe was developed for dried cayenne peppers or crushed red pepper. Fresh peppers contain more moisture, so substituting them directly may change the flavor and consistency. For the most predictable result, follow the recipe as written.
Is homemade sweet chili sauce shelf-stable?
No. This recipe is intended for refrigerated storage. It has not been tested as a canning recipe, so don’t seal it in jars for pantry storage or assume the vinegar makes it safe at room temperature.
Is homemade sweet chili sauce very spicy?
It has some heat from the cayenne peppers, but the sugar and vinegar provide a sweet, tangy balance. Since pepper heat varies, your finished sauce may be hotter or milder depending on the peppers you use.
