FAQ: Charred Lemongrass Mushroom & Scallion Oil Noodle Bowl
Can I use different mushrooms? Yes. Oyster, shiitake, king oyster, and cremini all work well and char beautifully.
Can this be made vegan? Yes. All components are naturally vegan as long as the dressing uses soy sauce instead of fish sauce.
Can I make the scallion oil ahead? Scallion oil stores well for several days in the refrigerator and can be used on noodles, rice, or vegetables.
Do I need to marinate the mushrooms? A short 5–10 minute marination helps the lemongrass and garlic cling to the mushrooms, but they will still char well without a long soak.
Can I serve this warm or cold? Both work. Warm noodles absorb scallion oil better, while chilled noodles make a refreshing summer bowl.
Mushrooms In Vietnamese Cooking

Mushrooms behave differently in Vietnamese cooking than they do in other recipes. They’re not used for “meatiness” alone—they’re chosen for texture, absorption, and how they carry seasoning. In Vietnamese cooking, you want mushrooms that caramelize well, hold their shape, and bring a warm, savory depth without turning watery.
