Flame Broiler Magic Sauce Recipe
Today, we're unlocking the secret with a homemade Flame Broiler Magic Sauce Recipe that tastes just like the real thing—maybe even better.
Equipment
- Medium saucepan
- Measuring cups and spoons
- Whisk
- Heat-safe spoon or spatula
- Airtight glass jar or bottle for storage
Ingredients
- 1 cup low-sodium soy sauce
- ½ cup brown sugar packed
- 2 tablespoons mirin or rice vinegar
- 2 tablespoons water
- 1 tablespoon sesame oil
- 1 tablespoon cornstarch mixed with 2 tbsp water to form a slurry
- 2 cloves garlic finely minced
- 1 teaspoon grated fresh ginger
- ½ teaspoon crushed red pepper flakes optional, for heat
- 1 tablespoon honey optional for extra sweetness
Instructions
- Prepare the slurry: In a small bowl, mix the cornstarch with 2 tablespoons of water. Set aside.
- Simmer the base: In a medium saucepan over medium heat, combine soy sauce, brown sugar, mirin, water, sesame oil, garlic, and ginger. Stir until the sugar dissolves completely.
- Add heat and sweetness: If using, add the red pepper flakes and honey. This gives the Flame Broiler Magic Sauce Recipe its signature depth and a slight kick.
- Thicken the sauce: Slowly stir in the cornstarch slurry while whisking. Bring the sauce to a gentle boil, then reduce heat and simmer for 2–3 minutes until thickened.
- Cool and store: Remove from heat and let it cool slightly. Strain if you prefer a smoother texture. Pour into a clean jar and refrigerate for up to two weeks.
Notes
- Use low-sodium soy sauce to avoid an overly salty taste.
- Fresh garlic and ginger give the best flavor—avoid powders when possible.
- Don’t skip the cornstarch slurry—it’s what gives the sauce its perfect consistency.
- Adjust sweetness to taste by adding more or less brown sugar or honey.
- Double the batch and store extra—it goes fast once your family gets a taste!
- Strain the sauce if you prefer a smoother, restaurant-style finish.
- Let it rest overnight—the flavor deepens beautifully after a day in the fridge.
