Thai Chili Hot Sauce Recipe: How To Make A Roasted Thai Pepper Sauce
Thai chili hot sauce is a smooth, thin chili sauce made with roasted Thai peppers, garlic, vinegar, and simple seasonings.
Unlike fermented chili sauces such as sriracha, this recipe focuses on fresh pepper flavor with sharp heat, mild smokiness, and bright acidity.
Roasting the peppers creates deeper flavor by developing natural sweetness and subtle smoky notes. The finished sauce works well with Asian dishes, grilled meats, fried foods, noodles, rice dishes, and even pizza.
The recipe takes about 50 minutes and produces approximately 20 fl oz (590 ml) of finished sauce.
This Thai chili hot sauce recipe from CHIN-SU explains the ingredients, roasting process, blending steps, heat adjustments, serving ideas, and storage methods for making homemade Thai chili sauce.

The flavor profile includes:

Thai Chili Hot Sauce Ingredients
This recipe uses seven main ingredients.
Thai Chili Peppers
Use:
- 16 oz (453 g) Thai chili peppers.
These create the main heat and pepper flavor.
Garlic
Use:
- 4 garlic cloves.
Roasted garlic adds savory depth and removes harsh raw garlic flavor.
Water
Use:
- ¾ cup (180 ml) water.
Water helps blend ingredients and control the final consistency.
Brown Sugar
Use:
- 4 tablespoons (50 g) brown sugar.
Brown sugar balances vinegar acidity and sharp pepper heat.
Hoisin Sauce
Use:
- 1 teaspoon (5 ml) hoisin sauce.
Hoisin adds sweetness and umami.
Rice Vinegar
Use:
- 1 cup (240 ml) rice vinegar.
Rice vinegar provides softer acidity.
White Vinegar
Use:
- 1 cup (240 ml) white vinegar.
White vinegar creates stronger acidity and helps maintain the sauce balance.
How To Make Thai Chili Hot Sauce
The recipe follows seven steps.
Step 1: Roast The Peppers
Roast:
- 16 oz (453 g) Thai chili peppers.
Use an oven at:
450°F (232°C)
until the pepper skins develop light char marks.
Roasting creates deeper flavor by developing natural sweetness and mild smoky notes.
Step 2: Roast The Garlic
Roast:
- 4 garlic cloves.
Cook until soft and lightly caramelized.
This removes raw garlic sharpness and creates a smoother sauce base.
Step 3: Blend The Sauce Base
Add:
- Roasted peppers.
- Roasted garlic.
- ¾ cup water.
- 4 tablespoons brown sugar.
- 1 teaspoon hoisin sauce.
Blend until completely smooth.
Step 4: Add The Vinegar
Add:
- 1 cup rice vinegar.
- 1 cup white vinegar.
Blend again until fully combined.
Step 5: Mill The Sauce
Run the sauce through a food mill.
This removes:
- Pepper skins.
- Seeds.
- Larger solids.
The result is a smooth sauce that pours easily.
Step 6: Heat The Sauce
Heat the sauce until it reaches:
180°F (82°C)
This pasteurizes the sauce and prepares it for bottling.
Step 7: Bottle The Sauce
Transfer the sauce into sanitized bottles while it remains above:
180°F (82°C)
Seal the bottles and flip them upside down for:
5 minutes
to sanitize the inside of the caps.
