These Thai-style stir-fried rice noodles are smoky, glossy, and packed with sweet-savory flavor from soy sauce, garlic, scallions, and basil. They come together fast in a hot wok, making them a budget-friendly noodle dinner for busy nights.
Prepare the fresh rice noodles by separating the sheets and cutting them into strips about 1 1/2 inches wide. If the noodles are cold or stuck together, let them sit at room temperature, then briefly loosen them with hot water and drain very well.
If using dried wide rice noodles as a substitute, soak or cook them according to the package directions until pliable but not mushy. Drain thoroughly; the noodles should be dry on the surface before stir-frying.
In a small bowl, stir the brown sugar with the hot water until dissolved. Add the fish sauce, Thai thin soy sauce, and Thai black soy sauce, then mix until smooth.
Heat a wok or large skillet over very high heat until it is almost smoking. Swirl in the canola oil so it coats the hot cooking surface.
Add the scallion whites, garlic, and Thai basil, if using. Stir-fry for about 10 seconds, just until fragrant, then add the prepared noodles and toss for 30 seconds to heat them through.
Pour the sauce over the noodles and toss quickly so every strand is coated. Stir-fry for about 1 minute, letting the noodles pick up a light smoky sear without breaking them apart.
Add the mung bean sprouts and scallion greens. Stir-fry for another minute, just until the sprouts soften slightly but still have some crunch. Serve immediately with chili oil if desired.
Use the widest fresh rice noodles you can find for the best chewy texture. The wok must be very hot before the noodles go in; if the pan is too cool, the noodles will steam and clump instead of searing. If Thai black soy sauce is unavailable, use dark soy sauce with a small pinch of extra brown sugar. For a vegetarian version, omit the fish sauce and add a little extra soy sauce to taste.
