Boil the Noodles: Cook the noodles according to the package instructions, subtracting 3 minutes from the recommended cooking time to achieve perfect al dente texture. Drain the noodles when done, but do not rinse them. Set a timer for your noodles and immediately get started on the next step.
Sauté the Aromatics: While the noodles are cooking, heat 1 Tablespoon of vegetable or canola oil in a large nonstick pan over medium heat. Add the minced garlic and grated ginger, frying until highly fragrant and lightly browned (about 5 minutes).
Build the Sauce Base: Pour the chicken stock, soy sauce, and rice vinegar into the pan, then add the brown sugar. Stir to combine all the ingredients and cook until the liquid starts to bubble.
Melt and Combine: Turn off the heat and remove the pan from the heat. Add the sesame oil and peanut butter to the pan. Stir continuously until the peanut butter is completely melted and smoothly combined into the sauce. If the sauce is still too thick, thin it out by adding 2–4 tablespoons of warm broth or water to help keep the sauce velvety smooth.
Coat the Noodles: Add the warm, drained noodles directly into the pan. Mix vigorously until the noodles are evenly coated with the savoury peanut sauce.
Garnish: Divide the noodles into 4 serving bowls. Generously sprinkle with toasted sesame seeds, chopped green onions, and fresh cilantro. If desired, top with crushed peanuts for extra crunch and a drizzle of chili oil for added heat.
Customize and Serve: Add your choice of cooked protein and extra vegetables if desired. Serve warm with a wedge of lime or lemon on the side!
