Ingredients for au su sauce
Pantry staples transform into a restaurant-worthy sauce with just ten ingredients.
| Ingredient | Amount | Notes |
|---|---|---|
| Canned Tomato Sauce š | 1 cup | San Marzano preferred for sweetness |
| Chipotle Peppers in Adobo š¶ļø | 2 tbsp | Minced, with 1 tsp adobo sauce |
| Light Soy Sauce š„« | 2 tbsp | Kikkoman preferred for balance |
| Granulated Sugar š | 1 Ā½ tbsp | Adjust to taste for sweetness |
| Rice Vinegar š¶ | 1 Ā½ tbsp | White vinegar works in pinch |
| Chili Oil š¶ļø | 1 tbsp | Homemade or store-bought |
| Garlic Cloves š§ | 2 cloves | Minced, fresh preferred |
| Sesame Oil š« | Ā½ tbsp | Toasted for aroma |
| Ground White Pepper š¶ļø | Ā¼ tsp | Freshly ground preferred |
| Cornstarch š¾ | Ā½ tsp | For thickening if needed |
The San Marzano tomato sauce is non-negotiable hereāits natural sweetness and low acidity create that velvety texture. Grab a 28-ounce can from the international aisle at Whole Foods or Trader Joe's for the best results. Chipotle peppers in adobo add that signature smoky depth, but check the can for moistureādrain and pat dry before mincing. Fresh garlic cloves make all the difference, but if you're short on time, garlic powder at half the amount works in a pinch. For the soy sauce, Kikkoman is my go-to, but any light soy will do.
No chipotle peppers? Smoked paprika plus a dash of liquid smoke gets you close. Running out of rice vinegar? Apple cider vinegar works, though it adds a slightly fruitier note. The chili oil can be homemade (toss chili flakes with neutral oil), or grab a bottle from the Asian marketāLa Choy is reliable. For thickening, cornstarch slurry is foolproof, but if you're feeling lazy, simmer the sauce longer to reduce naturally. The sugar is keyāadjust to taste after tasting the raw sauce before cooking.
This sauce tastes even better the next day as flavors meld. Store in an airtight glass jar in the fridge for up to 7 days, or freeze for 3 months in ice cube trays for single-serving portions. The sesame oil separates when refrigeratedājust give it a quick stir before using. Double the batch if you're prepping for the weekāit disappears fast on noodles, dumplings, or as a dipping sauce.
Why You'll Love This Recipe
- Pantry Magic: I swear by this sauceāno fresh herbs, no fancy prep. Just open a can of tomato sauce, dump in the adobo sauce from those chipotles, and stir. Thatās it. The light soy and sugar balance the smoky heat so well, itās like flavor alchemy.
- Smoky-Sweet Fix: Between us, this sauce is ridiculously addictive. The chipotle peppers give it a slow-building heat, while the rice vinegar cuts through it just enough to make you reach for another bite. Itās the kind of sauce that turns bland rice into a meal youāll actually look forward to.
- Leftover Hero: Make a double batchātrust me, you will. It keeps for weeks in the fridge and tastes even better the second day. Drizzle it over noodles, toss it with tofu, or even use it in scrambled eggs. My lazy Sundays now include this sauce in at least three meals.
- Budget Stretch: Honestly, this recipe is my secret weapon for stretching ingredients without sacrificing flavor. A can of tomato sauce, a jar of adobo peppers, and a bottle of soy sauce? Thatās less than $5 and enough to feed the whole family. Plus, the sugar and vinegar are pantry staples you probably already own.
Step-by-step instructions for Au Su sauce
This silky sauce comes together faster than you can say "chipotle."
š³ Step 1: Bloom the Aromatics in Chili Oil
Heat a small saucepan over medium-low heat and add the 1 tablespoon chili oil. Let it warm through for 30 seconds until you see tiny bubbles forming along the edges. This step activates the chili oil's flavor and prevents a harsh taste.
Add the 2 minced garlic cloves and cook for 30 seconds until they're just fragrantānot browned. Overcooking garlic turns it bitter, and we want that sweet, mellow flavor to shine in the finished sauce. Remove the pan from heat immediately after the garlic smells perfumed.
šØāš³ Step 2: Build the Sauce Base
Return the pan to medium heat and add the 1 cup canned tomato sauce, 2 tablespoons chipotle peppers in adobo (including 1 teaspoon adobo sauce from the jar), and 2 tablespoons light soy sauce. Stir constantly for 3-4 minutes until the mixture thickens slightly and the chipotle peppers soften.
Here's where the magic happens: the chipotle peppers should begin to break down, releasing their smoky depth. You'll notice the sauce darken and develop a rich, complex aroma. If it starts to stick, add 1 tablespoon water to loosen itāthis keeps the sauce silky rather than pasty.
š„ Step 3: Balance Flavors with Sweet and Tang
Reduce heat to low and whisk in the 1.5 tablespoons granulated sugar and 1.5 tablespoons rice vinegar. Let the sauce simmer gently for 2-3 minutes until the sugar dissolves completely and the vinegar brightens the flavors. Taste and adjustāyou want a perfect balance of sweet, tangy, and smoky.
This is your flavor checkpoint. If it's too sweet, add a splash more rice vinegar. If it's too sharp, stir in a pinch more sugar. The goal is that perfect harmony where none of the flavors overpower each other. I like to add a pinch of salt here if neededājust Ā¼ teaspoon at a time.
š„ Step 4: Finish with Umami and Silkiness
Remove the pan from heat and stir in the 0.5 tablespoons toasted sesame oil and 0.25 teaspoon ground white pepper. The sesame oil adds a nutty aroma that deepens the sauce's complexity, while the white pepper provides a subtle, sophisticated heat without the color of black pepper.
For the final touch, whisk together the 0.5 teaspoon cornstarch with 1 teaspoon cold water in a small bowl. Slowly stir this slurry into the warm sauce and cook over low heat for 1-2 minutes until it thickens to a glossy, coatable consistency. You want it to cling beautifully to noodles or proteins without being gluey.
ā° Step 5: Rest and Serve
Transfer the sauce to a bowl and let it rest for 5 minutes at room temperature. This resting period allows all the flavors to meld completely and the sauce to reach its perfect texture. The sauce should be silky yet still vibrant, with visible specks of chili oil and chipotle peppers.
Serve immediately over your favorite noodles, dumplings, or grilled meats. The sauce keeps well in the refrigerator for up to 5 daysājust reheat gently over low heat, stirring occasionally to prevent skin formation. For extra richness, drizzle with a touch more sesame oil before serving.
Pro Tips For Making Au Su Sauce
- STRAIN THE ADOBO SAUCE: I learned this the hard wayāblending the chipotle peppers straight from the adobo jar leaves a slimy, bitter residue that ruins the sauceās clean finish. Drain the peppers, then rinse them under cold water to remove any lingering oil or vinegar clinging to the flesh. Trust me, your sauce will taste brighter and more balanced.
- SIMMER LOW AND SLOW: This sauce isnāt a race. After adding the rice vinegar and sugar, drop the heat to a bare simmer (think tiny bubbles, not rolling). I used to rush it, and the sauce would turn cloyingly sweet or develop a harsh vinegar tang. Let it mellow for at least 15 minutesāyour taste buds will notice the difference.
- MEASURE SOY SAUCE BY WEIGHT: Light soy sauce is deceptively strong. Instead of eyeballing the 1-2 tablespoons most recipes suggest, weigh it: 15-20 grams for a standard batch. I was skeptical until I tried itāno more guessing if the sauce tastes flat or overpoweringly salty. A kitchen scale is your new best friend here.
- BALANCE SWEET AND ACID FIRST: Add half the sugar and rice vinegar first, taste, then adjust. I skip this step when Iām tired, and the sauce ends up either cloying or tart. Start with 1 teaspoon sugar and Ā½ teaspoon vinegar, simmer 5 minutes, then tweak. The goal? A sauce thatās tangy but not puckery, sweet but not syrupy. Your palate will thank you.
Perfect pairings for these flavors
Noodle Pairings
This sauce was made for egg noodles or udon, where its silky texture clings perfectly. Toss 8 ounces cooked noodles with 2 tablespoons sauce and top with sliced green onions and sesame seeds. For extra richness, add 1 teaspoon butter to the hot noodles before mixing. š
For a ramen-style bowl, use 4 ounces fresh ramen noodles and drizzle with 3 tablespoons sauce. Add sliced mushrooms, bok choy, and a soft-boiled egg for a restaurant-quality experience. The sauceās sweetness balances the umami of the broth beautifully.
Dumpling Dippers
Serve with steamed pork or shrimp dumplings for an irresistible pairing. Warm 12 dumplings in a steamer for 5 minutes, then dip in the sauce. The chipotleās smokiness cuts through the dumplingās fat, while the sweetness enhances their savory filling. š„
For potstickers, pan-fry them until crispy, then drizzle with sauce. The contrast of crispy bottoms and silky sauce is pure magic. I like to add a sprinkle of toasted sesame seeds for extra texture before serving.
Protein Pairings
Grilled chicken thighs or pork chops become showstoppers with this sauce. Brush 2 tablespoons sauce on cooked protein and broil for 2 minutes to caramelize slightly. The sauceās depth complements the meatās natural flavors without overpowering. š
For tofu, marinate firm tofu in 2 tablespoons sauce for 15 minutes before pan-frying. The sauceās tangy-sweet profile elevates the tofuās neutral taste, making it ideal for vegetarians. Serve with steamed greens for a complete meal.
Breakfast Twists
Use this sauce on scrambled eggs or chicken sausage for a savory breakfast upgrade. Stir 1 tablespoon sauce into 3 beaten eggs before cooking, or drizzle over fluffy scrambled eggs. The smoky chipotle adds unexpected depth to morning meals. š³
For breakfast tacos, spread 1 tablespoon sauce** on warm tortillas, then top with scrambled eggs, avocado, and cotija cheese. The sauceās sweetness balances the richness of the eggs perfectly.

The chipotle peppers add warmth while the tomatoes create a velvety texture that clings beautifully to noodles or proteins. Itās sweeter but more complex than standard sweet and sour.
Can I make this sauce without chipotle peppers?
Yes! Replace the chipotle with 1 teaspoon smoked paprika plus Ā½ teaspoon liquid smoke for a similar smoky flavor. For heat, add Ā½ teaspoon cayenne pepper or 1 teaspoon sriracha. The sauce will still be delicious but lose some of its signature depth.
How do I adjust the sweetness or spice level?
For less sweetness, reduce sugar by Ā½ teaspoon at a time. For more heat, add Ā½ teaspoon extra chili oil or a pinch of cayenne. Taste as you goāthis sauce is all about balance! The chipotleās smokiness should shine without overpowering.
Can I use this sauce as a marinade?
Use Ā¼ cup sauce per pound of protein (chicken, pork, or tofu) for 15-30 minutes before cooking. The sweetness caramelizes beautifully on the grill or pan, while the chipotle adds smoky flavor. For extra marinade power, add 1 teaspoon honey to the sauce.
How long does this sauce keep, and can I freeze it?
Store in an airtight container in the fridge for up to 5 days. For freezing, portion into ice cube trays, freeze, then transfer to a bag. Thaw overnight in the fridgeānever microwave directly. The sauce thickens when refrigerated, so stir well before reheating.
