How to Thicken Teriyaki Sauce: 8 Steps

Teriyaki sauce is a popular choice for many dishes thanks to its savory, sweet flavor profile. However, thin sauce may not adhere well to food or provide the desired consistency. Here are eight simple steps to thicken teriyaki sauce and enhance your culinary creations.
1. Start with a cold sauce: Before you begin thickening your teriyaki sauce, ensure it’s cold. Thickening agents work best when the sauce is not already hot.
2. Choose a thickening agent: There are many options for thickening agents, such as cornstarch, flour, or arrowroot powder. Each of these will produce slightly different results in terms of consistency and appearance; choose based on personal preferences and dietary restrictions.
3. Measure the thickening agent: The amount of thickening agent you’ll need depends on the amount of sauce and how thick you want it. Typically, about 1 tablespoon of cornstarch/flour per cup of liquid is sufficient for a moderately thicker teriyaki sauce.
4. Mix a slurry: To avoid lumps forming in the sauce when adding the thickening agent, first mix it with cold water to create a slurry—a pourable mixture with a uniform consistency. For every tablespoon of cornstarch/flour, stir in 1-2 tablespoons of cold water until smooth.
5. Heat the teriyaki sauce: In a saucepan over medium heat, start warming the teriyaki sauce. Stir occasionally to distribute heat evenly and prevent burning.
6. Add slurry gradually: Once the teriyaki sauce starts to heat up but hasn’t reached boiling point yet, slowly pour in the slurry while constantly stirring. This ensures an even distribution of the thickening agent throughout the sauce.
7. Bring to a boil and simmer: As soon as everything is combined, bring the teriyaki sauce to a boil, then reduce the heat to low, and let it simmer for 1-2 minutes. This cooking process activates the thickening agent and allows it to achieve its full potential.
8. Adjust the thickness: If the sauce isn’t as thick as you want it, repeat steps 4 through 7 with additional thickening agent. Remember to taste-test the sauce in case adjustments to flavor are needed.
Now you have a thicker teriyaki sauce that will coat your food evenly and provide a more satisfying dining experience. Enjoy!
