This thick teriyaki sauce is glossy, savory-sweet, and ready in about 15 minutes. A little cornstarch gives it a dependable, spoon-coating texture, while ginger and garlic add fresh flavor without making the sauce complicated.
Ingredients
- 1/2 cup (120 ml) low-sodium soy sauce
- 1/2 cup (120 ml) water, divided
- 1/4 cup (50 g) packed light brown sugar
- 2 tablespoons honey
- 1 tablespoon rice vinegar
- 1 teaspoon finely grated fresh ginger
- 1 small garlic clove, finely grated or minced
- 1 tablespoon cornstarch
- 1 tablespoon cold water
- 1 teaspoon toasted sesame oil, optional
Instructions
- Prepare the thickener. In a small bowl, whisk the cornstarch with 1 tablespoon cold water until smooth. Set it beside the stove; starch settles quickly, so stir it again just before using.
- Combine the sauce ingredients. Add the soy sauce, 1/2 cup water, brown sugar, honey, rice vinegar, ginger, and garlic to a small saucepan. Whisk to dissolve the sugar.
- Bring to a gentle simmer. Set the saucepan over medium heat and stir occasionally. When small bubbles appear around the edges, reduce the heat to medium-low. Simmer for 3 to 5 minutes, stirring so the sugar does not catch on the bottom.
- Thicken the sauce. Stir the cornstarch slurry once more, then pour it into the simmering sauce in a thin stream while whisking. Keep the sauce at a gentle simmer for 1 to 2 minutes, stirring constantly, until it turns glossy and lightly coats a spoon. Avoid a hard boil, which can make the sauce sputter or thicken unevenly.
- Finish and cool. Remove the pan from the heat and stir in the sesame oil, if using. The sauce will continue to thicken as it cools. Use it warm, or let it cool before transferring it to a clean container.
Tips
- Adjust thickness gradually. This recipe makes a thick, brushable sauce. If you want it thicker, mix 1 teaspoon cornstarch with 1 teaspoon cold water, add it to the simmering sauce, and cook for another minute. If it is too thick, whisk in warm water a teaspoon at a time.
- Choose your soy sauce carefully. Low-sodium soy sauce keeps the sweetness balanced. If using regular soy sauce, the result will be saltier; you can begin with 1/3 cup soy sauce and add more to taste. For a gluten-free version, use certified gluten-free tamari.
- Keep the heat moderate. Sugar can scorch, and garlic can turn bitter if fried or boiled vigorously. Stir as the sauce simmers and reduce the heat if it bubbles rapidly.
- Use a clean spoon or brush. If you brush sauce onto raw meat, do not put that same sauce back in the serving container. Reserve a clean portion first, or bring sauce that touched raw meat to a full boil before serving.
Serving Suggestions
Brush the sauce over grilled or pan-seared chicken, salmon, tofu, or vegetables near the end of cooking. Its sugar content can burn over high heat, so apply it during the final few minutes rather than throughout a long cook. For a glaze, brush on a thin layer, let it set briefly, and repeat if you want a more pronounced coating.
You can also spoon it over rice bowls, noodles, steamed vegetables, or cooked meat. Start with a small amount because the flavor is concentrated. Thin a portion with a splash of warm water if you want a looser drizzle; do not thin the entire batch unless you plan to use it that way.
Variations
- Less sweet: Reduce the brown sugar to 2 tablespoons and omit the honey. Taste after simmering and add a little more sweetener only if needed.
- More ginger-forward: Increase the grated ginger to 2 teaspoons. Add a pinch of red pepper flakes for gentle heat.
- No honey: Replace it with an equal amount of brown sugar or maple syrup. The flavor will vary slightly, but the sauce will still thicken as directed.
- Without cornstarch: Simmer the sauce uncovered over low heat until reduced to your preferred consistency, stirring often. This takes longer and yields less sauce; stop while it is a little thinner than you want, since it thickens as it cools.
Storage and Reheating
Cool the sauce promptly, then refrigerate it in a clean, airtight container within 2 hours of cooking. Keep it refrigerated at 40°F (4°C) or colder and use within 5 days. For longer storage, freeze it in a freezer-safe container for up to 3 months; leave a little room for expansion and thaw it overnight in the refrigerator. Discard sauce that has been left at room temperature for more than 2 hours, or more than 1 hour when the temperature is above 90°F (32°C).
Reheat only the amount you need in a small saucepan over low heat, stirring until hot. Add water a teaspoon at a time if it has become too firm. You can also microwave it in a microwave-safe bowl in short intervals, stirring between each. Reheating may loosen the sauce, so simmer briefly if it needs to thicken again. Avoid repeatedly warming and cooling the whole batch.
Frequently Asked Questions
How do I know when the sauce is thick enough?
It should look glossy and cling to the back of a spoon, leaving a clear line when you draw a finger across the coated spoon. It will become thicker after cooling, so take it off the heat before it reaches a paste-like consistency.
Why did my sauce turn lumpy?
The cornstarch may have been added dry or mixed into warm liquid. Always dissolve it in cold water first, stir the slurry just before adding, and whisk while pouring it into gently simmering sauce. If small lumps remain, strain the sauce through a fine-mesh sieve.
Can I make this sauce ahead?
Yes. Make it up to 5 days ahead and keep it covered in the refrigerator. It will set more firmly when cold; warm it gently and stir in a little water if needed before serving.
Can I use it as a marinade?
Yes, but this thick, sweet version is best used as a finishing glaze. For marinating, thin a portion with water and marinate meat in the refrigerator, never on the counter. Discard used marinade or boil it thoroughly before using it as a sauce; reserving a clean portion before it touches raw food is easier.
Is teriyaki sauce supposed to contain cornstarch?
Not every teriyaki sauce does. This recipe uses cornstarch for a quick, reliably thick texture. You can omit it and reduce the sauce by simmering, though that takes longer and concentrates the salty and sweet flavors.
Can I make it gluten-free?
Yes. Replace the soy sauce with gluten-free tamari, checking the label to confirm it is certified gluten-free. The remaining ingredients are generally gluten-free, but check their labels as well if you need to avoid gluten strictly.
