Equipment

  • Chef's Knife
  • Cutting Board
  • Large Bowl
  • Small bowl or measuring cup
  • Colander

Ingredients
  

  • 2 large English cucumbers (about 1 1/2 lbs)
  • 1 1/2 tsp kosher salt (Diamond Crystal; use 1 tsp Morton's)

For the dressing

  • 3 tbsp unseasoned rice vinegar
  • 1 tbsp soy sauce (or tamari for gluten-free)
  • 2 tsp toasted sesame oil
  • 2 tsp sugar (white, honey, or maple syrup)
  • 2 cloves garlic, grated
  • 1/2 tsp red pepper flakes (or to taste)
  • 1 tbsp sesame seeds, toasted

Instructions
 

  • Smash the cucumbers with the side of a chef's knife until they crack open. Cut crosswise into bite-sized chunks (about 1 inch). The rough edges grab dressing better than clean slices.
  • Toss the cucumber chunks with the salt in a large bowl. Transfer to a colander set over a bowl (or leave in the bowl). Let sit for 10 minutes. You'll see water pooling – that's the salt doing its job.
  • While the cucumbers sit, whisk together the rice vinegar, soy sauce, toasted sesame oil, sugar, and grated garlic in a small bowl until the sugar dissolves. The smell of garlic and sesame oil mixing is the first sign you're on the right track.
  • Pour off the liquid that collected from the cucumbers. Do not rinse them – a little residual salt adds flavor.
  • Pour the dressing over the drained cucumbers. Toss well to coat every piece. The dressing should cling to the rough edges.
  • Transfer to a serving bowl. Sprinkle with toasted sesame seeds and red pepper flakes. Let sit 5 minutes before serving so the flavors marry. The five-minute rest is worth it.

Notes

Storage: This salad is best within 2 hours of dressing. For meal prep, store the salted drained cucumbers and the dressing separately in the fridge for up to 3 days. Toss together right before serving. Do not freeze.
Substitutions: Use regular cucumbers – peel and seed them first. Replace soy sauce with tamari for gluten-free. Use low-sodium soy sauce and reduce salt to 1 tsp if needed. Add cilantro, mint, crushed peanuts, or edamame to turn it into a meal.
Pro tip: Don't skip salting – it's the key to crunchy cucumbers. Smashing instead of slicing creates more surface area for the dressing. Toast sesame seeds in a dry pan over medium heat for 90 seconds until fragrant.
