Ingredients

  • 1 lb Ground beef (80/20) (80/20 blend preferred for juiciness)
  • 1/4 cup Mayonnaise
  • 2 tbsp Sriracha or Asian hot sauce (Adjust to taste)
  • 1 large Carrot (Julienned)
  • 1 medium Jalapeño (Sliced)
  • 1/2 cup White vinegar
  • 3 tbsp Sugar
  • 1 tsp Salt (Plus more for seasoning)
  • 1/4 cup Warm water
  • 1/3 large Cucumber (Cut into planks)
  • 1/2 cup Cilantro (Fresh leaves)
  • 3 pieces Burger buns (Soft sandwich buns)

Instructions

  1. Defrost Ground Beef

    Remove 1 lb ground beef from the freezer and place on a plate in the refrigerator for 2 days to thaw slowly. Place plate under the package to catch any drips.

    Time: PT48H

    Temperature: 4°C

  2. Portion Burger Patties

    Divide the thawed ground beef into three equal portions (about 3 oz each). Roll each into a ball. If you don't have a scale, use a 1/4 cup measure per patty.

    Time: PT5M

  3. Make Spicy Mayo

    In a small bowl, combine 1/4 cup mayonnaise, 2 tbsp sriracha or Asian hot sauce, and a pinch of salt. Mix until fully incorporated. Taste and adjust heat as desired.

    Time: PT2M

  4. Prepare Quick Pickled Vegetables

    Julienne 1 large carrot by hand (square off, cut thin planks, then thin sticks). Slice 1 jalapeño into thin rounds. Place both in a bowl. Add 1/2 cup white vinegar, 3 tbsp sugar, 1/2 tsp salt, and 1/4 cup warm water. Stir until sugar dissolves. Let sit for at least 30 minutes.

    Time: PT15M

  5. Prepare Cucumber and Cilantro

    Cut cucumber into planks (about 1/4 inch thick, lengthwise). Wash and dry cilantro leaves.

    Time: PT3M

  6. Toast Burger Buns

    Preheat a cast-iron skillet over medium-high heat for several minutes. Place buns cut side down and toast until golden brown. Remove and set aside.

    Time: PT3M

    Temperature: Medium-high

  7. Cook Smash Burger Patties

    Increase skillet to medium-high heat. Place a beef ball in the hot pan. Immediately smash flat with a sturdy spatula (or use parchment between spatula and meat). Press edges down. Season with salt. Cook for 2 minutes until a deep brown crust forms. Flip, season again, and cook 1 more minute until cooked through (internal temp 160°F/71°C). Repeat for all patties.

    Time: PT10M

    Temperature: Medium-high

  8. Drain Pickled Vegetables

    Drain the pickled carrots and jalapeños well before assembling to avoid soggy buns.

    Time: PT2M

  9. Assemble the Banh Mi Smash Burgers

    Spread spicy mayo on the bottom bun. Layer cucumber planks, then the cooked burger patty. Top with drained pickled carrots and jalapeños, then fresh cilantro leaves. Add a little more mayo to the top bun, close, and serve immediately.

    Time: PT5M

  10. Cleanup

    Wash all bowls, utensils, skillet, and cutting board. Wipe down counters and stove.

    Time: PT10M

Chef Tips from the Video

  • Smashing the burger right away is key for a crispy crust.
  • Taste the pickle brine before adding vegetables to ensure a good balance.

Troubleshooting

Burger patty falls apart when smashing.

Form the patty into a tight ball and smash immediately after placing in the hot pan.

Burger is dry.

Use 80/20 ground beef for adequate fat content and avoid overcooking.

Buns get soggy.

Drain pickled vegetables thoroughly and toast buns well.

Pickles taste too sharp or too sweet.

Adjust vinegar, sugar, and salt in the brine to your taste before pickling.

Storage

Refrigerator: Store cooked patties, pickled vegetables, and spicy mayo separately in airtight containers for up to 3 days.

Freezer: Cooked patties can be frozen for up to 2 months. Thaw and reheat before assembling.

Room temperature: Assembled burgers should be eaten immediately. Mayo and pickles should not be left out for more than 1 hour.

Make-Ahead Tips

  • Pickled vegetables and spicy mayo can be made up to 2 days in advance and stored in the refrigerator.
  • Burger patties can be portioned and refrigerated a day ahead.
