Notes
Lemongrass
- You can find fresh lemongrass in Asian supermarkets. If you can't find fresh, they usually carry frozen minced lemongrass that works too! Adding 1/2 tbsp minced lemongrass along with the garlic when sautéing works too.
Tips & Variations
- Swap bok choy with spinach, napa cabbage, or any leafy greens.
- Add mushrooms for extra umami.
- For more spice, add fresh bird’s eye chili to the broth.
