Mongolian Barbecue Sauce Recipe: Sweet and Savory Umami Glaze

This sauce captures the bold, complex flavors of Mongolian barbecue in a versatile glaze that elevates any protein. A balance of sweet, savory, and umami makes it irresistible.

With just a few pantry staples and 10 minutes, you’ll create a sauce that’s perfect for stir-fries, grilling, or dipping. Its rich depth comes from soy, hoisin, and fresh aromatics.

Ingredients for Mongolian Barbecue Sauce

Nine ingredients transform into a bold, umami-packed glaze in minutes. Nothing complicated here.

The hoisin is key—Koon Chun is the gold standard, but Kikkoman’s version at most grocery stores works fine. Soy sauce matters too: low-sodium lets you control the salt. I grab mine from Whole Foods bulk bins (cheaper, and you can buy exactly what you need). The ginger and garlic? Fresh only—those jarred minced things just don’t cut it here.

Out of hoisin? Mix 2 tbsp soy sauce + 1 tbsp molasses + 1 tsp five-spice powder. No rice vinegar? Apple cider vinegar in a pinch (slightly fruitier). Brown sugar can be swapped for honey or maple syrup—just know the flavor shifts a bit. Skip the cornstarch if you like it looser, but it helps the sauce cling to whatever you’re glazing.

This keeps 1 week in the fridge—if it lasts that long. Freeze for up to 3 months in a jar (leave headspace). The flavors deepen overnight, so make it a day ahead if you can. (worth the wait)

Instructions

This sauce comes together quickly with just a few simple steps and delivers bold flavor.

Step 1: Combine the Base Ingredients

In a medium saucepan, whisk together the 0.5 cup soy sauce, 0.5 cup hoisin sauce, 0.33 cup brown sugar, and 3 tbsp rice vinegar. I like to start with these foundational elements to build depth right away.

The hoisin adds thickness and a complex sweetness, while the rice vinegar brings a bright tang that balances the richness. Stir well until the brown sugar begins to dissolve—this prevents any grainy texture in the finished sauce.

Step 2: Add Aromatics and Heat

Place the saucepan over medium heat and add the 4 cloves fresh garlic cloves (minced) and 1 tbsp fresh ginger (finely grated). Stir constantly for 30-45 seconds until the mixture becomes fragrant.

Be careful not to let the garlic burn—it can go from perfect to bitter in seconds. The ginger and garlic should infuse the sauce with their pungent, warm flavors without overpowering it.

Next, stir in the 1 tbsp sesame oil and 0.5 tsp red pepper flakes. The sesame oil adds a toasty depth, while the red pepper flakes introduce a subtle heat that builds as the sauce simmers.

Step 3: Thicken and Finish

In a small bowl, mix the 1 tbsp cornstarch with the 0.25 cup water until smooth. Slowly pour this slurry into the saucepan while whisking continuously to prevent lumps.

Bring the mixture to a gentle simmer over medium heat, then reduce to low heat. Let it cook for 3-4 minutes, stirring often, until the sauce thickens enough to coat the back of a spoon.

You’ll notice the sauce transform from a thin liquid to a glossy, velvety glaze. This consistency is perfect for clinging to meats or veggies during stir-frying or grilling.

Step 4: Cool and Store

Remove the sauce from the heat and let it cool to room temperature. The flavors will meld further as it sits, creating a more harmonious balance of sweet, salty, and umami notes.

Transfer the sauce to an airtight jar or container. It will keep in the refrigerator for up to 2 weeks. If the sauce thickens too much in the fridge, simply stir in a splash of warm water to loosen it before using.

Flavor Customization for This Dish

Spice It Up

For extra heat, increase the red pepper flakes to 1 tsp or add 1 tbsp sriracha for a different kind of kick. I sometimes toss in a few slices of fresh jalapeño while simmering—just

Sweeter Twist

If you prefer a sweeter profile, add 2 tbsp honey or maple syrup along with the brown sugar. This works especially well if you’re using the sauce for glazing ribs or chicken wings. The extra sweetness caramelizes beautifully under the broiler.

Umami Boost

Deepening the umami is easy: stir in 1 tbsp fish sauce or 1 tsp oyster sauce at the end. I’ve also experimented with 1 tbsp soy paste from my local Asian market—it adds a rich, fermented complexity that’s hard to beat.

Citrus Brightness

A splash of 2 tbsp orange juice or 1 tbsp lime zest brightens up the sauce and cuts through the richness. This works wonders if you’re pairing it with seafood or lighter proteins like shrimp or tofu.

Smoky Depth

For a BBQ-inspired twist, add ½ tsp smoked paprika or a dash of liquid smoke. It’s a nod to my pitmaster roots and pairs surprisingly well with the hoisin base. Just a little goes a long way. 🔥

Herbal Notes

Fresh herbs can add a new dimension. Try stirring in 2 tbsp chopped cilantro or 1 tbsp Thai basil at the end. I forage wild herbs sometimes, and a sprinkle of lemon balm can add a unique, citrusy touch.
