Din Tai Fung Spicy Wonton Sauce Recipe: Authentic Chili Oil Infusion

This authentic sauce captures the signature heat and depth of Din Tai Fung’s famous creation. A precise blend of chili oil, soy, and aromatics delivers the restaurant-quality flavor you crave.

With simple ingredients and a 10-minute process, you’ll achieve that perfect balance of spicy, savory, and slightly sweet notes. Store in the fridge for up to two weeks.

Ingredients for Din Tai Fung Spicy Wonton Sauce

Nine ingredients. Ten minutes. Restaurant magic at home.

The chili oil is non-negotiable here—Lao Gan Ma or Fly By Jing deliver that authentic heat and sediment you need. Don’t skimp on the soy sauce either; Pearl River Bridge light soy is the gold standard for this. Black vinegar adds that signature tang (Chinkiang vinegar if you can find it at an Asian market). The ginger and garlic? Fresh only—no powders.

No black vinegar? Rice vinegar with a pinch of sugar works in a pinch. Short on green onions? Shallots or white onion can stand in (though the color won’t be as pretty). If you’re out of sesame seeds, skip them—the sauce is still delicious. The sugar can be swapped for honey or agave, but keep the amount the same.

This keeps 2 weeks in the fridge, but honestly it’s so good it’ll be gone sooner. Store in a glass jar (the oil can stain plastic). Stir before using—those chili flakes settle fast.

Step-by-Step Instructions for Din Tai Fung Spicy Wonton Sauce

This is how you build authentic restaurant flavor at home with precision and depth.

Step 1: Bloom Aromatics in Hot Chili Oil

Heat the 0.5 cup chili oil in a small saucepan over medium-low heat until it just begins to shimmer. Add the 4 cloves minced garlic and 1 tbsp grated ginger to the warm oil. You’ll see the garlic sizzle gently—this is exactly what you want.

Cook for 2-3 minutes until the garlic turns light golden brown and becomes fragrant. Watch closely—garlic burns easily and bitter garlic ruins the sauce. The ginger will soften slightly. Remove from heat immediately once the garlic reaches that perfect golden color to prevent overcooking.

Step 2: Combine Liquid Base and Sweeten

In a heatproof bowl, combine the 0.33 cup light soy sauce, 2 tbsp black vinegar, and 1 tbsp granulated sugar. Stir until the sugar completely dissolves—this might take a minute as the sugar incorporates into the colder liquids.

Now carefully pour the hot chili oil with aromatics into this soy mixture. The residual heat from the oil will help meld all the flavors together. I always use a fine-mesh strainer if I want a smoother sauce, but leaving the garlic and ginger bits in adds texture and authentic Din Tai Fung character.

Step 3: Finish with Sesame and Green Onion

Stir in the 1 tbsp sesame oil—this adds a crucial nutty depth that balances the heat. The sauce should now have a glossy sheen and rich amber color. Let it cool for 5 minutes before adding the 3 whole thinly sliced green onions.

The green onions maintain their bright color and crisp texture when added to the slightly cooled sauce. If you add them too early, they’ll wilt and lose their freshness. This is the moment the sauce transforms from good to restaurant-quality.

Step 4: Garnish and Rest for Maximum Flavor

Sprinkle the 1 tsp toasted sesame seeds over the surface of the sauce. These add the final visual pop and nutty crunch that makes this sauce irresistible with wontons or dumplings.

Let the sauce rest for at least 30 minutes at room temperature before using. This resting period allows all the flavors to fully marry—the chili oil’s heat will mellow slightly while the soy and vinegar create that perfect tangy-sweet base. The sauce will thicken slightly as it cools, coating your wontons beautifully.

Storing and Reheating Leftovers

Refrigerator Storage

Transfer the cooled sauce to a glass jar with a tight-fitting lid—I use 16-ounce mason jars for perfect portioning. Store in the fridge at 40°F or below for up to 2 weeks. The flavors actually deepen over time as the aromatics continue to infuse. ❄️

Freezer Storage

For longer storage, freeze in ice cube trays first, then transfer to an airtight container. This sauce freezes beautifully for up to 3 months without texture changes. Thaw overnight in the fridge before using.

Room Temperature Use

If serving at a party, the sauce can sit at room temperature for up to 2 hours. I recommend placing the jar in a bowl of ice to maintain freshness. Stir occasionally to redistribute the chili flakes.

Reheating Gently

For warm sauce, heat in a small pan over low heat for 2-3 minutes. Never microwave—it can separate the oils and make the texture uneven. If too thick, thin with 1 tsp warm water and stir well. 🔥

Reviving Separated Sauce

If the sauce separates after storage, simply whisk vigorously or blend briefly with an immersion blender. The natural emulsifiers in the garlic and ginger will bring it back together. I find this happens most often after freezing.
