Vietnamese Lemongrass Beef Quinoa with Fresh Herb Salad

Steps

1. 1

   Slice the beef

   • Using a sharp knife and a cutting board, slice the sirloin against the grain into thin pieces about ¼ inch thick.
   • If the beef is warm or difficult to slice cleanly, freeze for 15 minutes first.
   • Keep the slices on a plate.

   Ready when: Slices are uniform, thin, and roughly the thickness of a coin

   Tip: Slicing against the grain (perpendicular to the long muscle fibers) ensures the meat will be tender even with quick cooking

2. 2

   Make the marinade

   • In a small mixing bowl, combine the minced lemongrass, minced garlic, 3 tablespoons fish sauce, 2 tablespoons lime juice, 1 tablespoon brown sugar, and 2 tablespoons olive oil.
   • Stir until the sugar dissolves and the mixture is well combined.
   • It should smell intensely aromatic.

   Ready when: Sugar is completely dissolved and mixture is smooth

   Tip: Mince the lemongrass finely so its flavor distributes throughout the beef; large pieces can taste woody

3. 3

   Marinate the beef

   • Add the sliced beef to the marinade and toss with a spoon until every piece is coated.
   • Cover with plastic wrap or a plate and let sit at room temperature for 25–30 minutes.
   • The lemongrass and garlic will begin to perfume the meat.

   Ready when: Beef has darkened slightly and smells fragrant

   Tip: Don't marinate longer than 1 hour—the lime juice can make the beef mushy if left too long

4. 4

   Cook the quinoa

   • In a medium saucepan, combine the rinsed quinoa, 2 cups water or broth, and ½ teaspoon salt.
   • Bring to a boil over medium-high heat, then reduce heat to medium-low, cover with a lid, and simmer for 15 minutes until the liquid is fully absorbed and you can see the white spiraled germ of each quinoa grain.

   Ready when: All liquid is absorbed, each grain shows a small white spiral tail, and grains are translucent

   Tip: Don't skip rinsing the quinoa—it removes the bitter saponin coating that many people dislike

5. 5

   Rest the quinoa

   • Remove the saucepan from heat and let it sit covered for 5 minutes.
   • Then remove the lid and fluff the quinoa gently with a fork, breaking up any clumps.

   Ready when: Quinoa is light, fluffy, and grains are fully separated

6. 6

   Prep herbs and vegetables

   • On a clean cutting board, tear the mint leaves into rough bite-sized pieces, discarding any tough stems.
   • Tear or slice the basil similarly.
   • Finely slice the red onion into half-moons.
   • Thinly slice or julienne the cucumber into matchsticks.
   • Thinly slice the red chili and remove seeds if you prefer less heat.
   • Place all prepped items in a large bowl.

   Ready when: All vegetables and herbs are finely sliced and ready to combine

   Tip: Do this while the quinoa cooks so you're ready to move quickly; fresh herbs bruise if cut too far ahead

7. 7

   Make the dressing

   • In a small bowl, whisk together 4 tablespoons fresh lime juice, 2 tablespoons fish sauce, 1 tablespoon brown sugar, and 2 tablespoons olive oil.
   • Stir or whisk until the sugar dissolves.
   • Taste the dressing and adjust: if it's too salty, add a squeeze more lime; if it's too sharp, add a pinch more brown sugar.
   • You should taste lime, salt, and a hint of sweetness in balance.

   Ready when: Sugar is dissolved and flavors are in balance

   Tip: Taste as you go—your preference for salt, acidity, and sweetness should drive the final flavor; don't be shy

8. 8

   Sear the beef

   • Remove the beef from the marinade and pat it very dry with paper towels—this helps develop a golden crust.
   • Heat a large skillet or wok over medium-high heat for 2 minutes until it is very hot and just begins to smoke.
   • Working in two batches so as not to overcrowd the pan, add half the beef in a single layer and cook without moving it for 2–3 minutes per side, until the edges are golden brown and the interior reaches 130–135°F (54–57°C) for medium-rare.
   • Transfer to a clean plate and repeat with the second batch.

   Ready when: Exterior is deep golden brown; interior is pink in the center and warm throughout

   Tip: Pat the beef very dry—any moisture from the marinade will steam the meat instead of searing it. Don't move the meat around; let it sit and develop a crust

9. 9

   Combine the herb salad

   • Pour the dressing over the bowl of herbs, red onion, cucumber, and chili.
   • Toss everything together gently but thoroughly with a spoon or your hands until all the vegetables and herbs are coated with dressing.
   • Taste and add a pinch of salt if needed.

   Ready when: All components are evenly coated with dressing and beginning to soften slightly

   Tip: Toss the salad just before serving—if it sits too long, the herbs will wilt and cucumber will release water

10. 10

    Assemble and serve

    • Divide the fluffy cooked quinoa among four bowls or serving plates, mounding it in the center.
    • Top each serving with a portion of the warm seared beef.
    • Spoon a generous amount of the herb salad and its dressing over and around the beef.
    • Garnish with sesame seeds if desired.
    • Serve immediately while the beef is still warm and the herbs are fresh.
