Tips
Ice-bath the blanched bean sprouts immediately to preserve their crunch and prevent overcooking; this textural contrast is essential to the dish.
Reserve one tablespoon of dressing before stir-frying the mushrooms so you have enough to finish the bowl with the sesame-spring onion mixture.
Assemble components separately and combine just before eating to keep the rice fluffy and vegetables fresh rather than steamed together.
Good to Know
Refrigerate cooked rice and stir-fried mushrooms separately in airtight containers for up to 3 days. Store raw vegetables separately to preserve crispness. Dressing keeps 5 days refrigerated.
Prepare rice, blanch bean sprouts, and make dressing up to 1 day ahead. Stir-fry mushrooms no more than 4 hours before serving. Shred carrot and slice spring onion up to 8 hours ahead.
Serve warm with rice and hot mushroom topping. Assemble just before eating. Pair with miso soup or light salad for a complete meal.
Common Mistakes
Skip the ice bath after blanching to avoid mushy bean sprouts that lose their signature crunch.
Don't evaporate the mushroom sauce completely to prevent the vegetables from drying out; stop when mostly reduced.
Add dressing too early to avoid wilting the fresh vegetables and vegetables becoming soggy.

FAQ
Can I make this ahead for meal prep?
Yes, cook rice and mushrooms separately and store for 3 days. Keep fresh vegetables apart. Assemble and drizzle dressing just before eating to prevent sogginess.
What if I don't have watercress?
Spinach, arugula, or mixed greens work well. Baby spinach wilts slightly from the warm rice, adding tenderness. Arugula keeps a peppery bite.
Can I freeze the cooked components?
Rice freezes well for 2 months. Cooked mushrooms freeze for 1 month but lose some texture. Fresh vegetables don't freeze. Thaw rice overnight in the fridge before reheating gently.
