Ingredients

Equipment

• Mixing bowl
• Measuring cups and spoons
• Whisk or fork for mixing
• Small saucepan or skillet
• Knife and cutting board
• Stir-fry wok or large skillet (for cooking lo mein)
• Spatula or wooden spoon

Instructions

1. Prepare the sauce base: In a mixing bowl, combine the soy sauce, oyster sauce (or mushroom sauce for vegetarian), sesame oil, and brown sugar. Whisk these together until the sugar is dissolved and the mixture is smooth.
2. Mix the slurry: In a separate small bowl, mix the cornstarch with water until completely dissolved. This will be used to thicken the sauce later.
3. Sauté aromatics: Heat a small saucepan over medium heat. Add a tiny splash of vegetable oil, then sauté the minced garlic and ginger for about 30 seconds until fragrant but not browned.
4. Add broth and sauce mixture: Pour in the vegetable broth followed by the mixed sauce base. Stir well to combine.
5. Simmer and thicken: Bring the sauce to a gentle simmer. Slowly whisk in the cornstarch slurry, stirring constantly to avoid lumps. Cook for another 1-2 minutes until the sauce thickens to a glossy consistency.
6. Season: Add white pepper and chili flakes if using. Adjust seasoning to taste — add more soy sauce or sugar if desired.
7. Use immediately: Pour this sauce over your cooked noodles and vegetables in the wok, toss well to coat, and serve hot for the best flavor experience.

Tips & Variations

Tip: For an extra depth of flavor, add a splash of Shaoxing wine or dry sherry while simmering the sauce. It adds a subtle complexity that’s reminiscent of authentic Chinese takeout.

If you want to make this sauce vegan, simply substitute oyster sauce with a mushroom-based vegetarian oyster sauce or hoisin sauce. This keeps the umami intact while accommodating dietary preferences.

For a gluten-free version, use tamari instead of soy sauce and ensure your oyster or mushroom sauce is gluten-free.

Feeling adventurous? Try adding freshly grated orange zest or a teaspoon of rice vinegar for a bright twist.

This sauce also works beautifully as a marinade for tofu or tempeh.
