Watch How to Make This Salad

Why You'll Love This Recipe

  • Super easy but flavorful: All you have to do is cut the veggies and mix everything, that’s it! The flavor is well-balanced and rich in umami, so it doesn’t taste as simple as it is 🙂
  • Easily customizable: You can play around with any veggies of your choice, such as bean sprouts, cabbage, or even winter vegetables like kabocha squash!

Notes on Ingredients

See the recipe card for the full ingredients list.

Ingredients to make Japanese tomato salad with cucumbers and bonito flakes.
  • Maple syrup: Use 100% pure maple syrup for the best flavor.
  • Bonito flakes: Called katsuobushi in Japanese, these are dried, smoked, and fermented fish that are shaved paper-thin. They add a deep umami flavor and wonderful aroma to any dish.

💡You can find these ingredients at Japanese or Asian grocery stores, or online at Amazon or Weee!

How to Make This Salad

Cut tomatoes into bite-sized pieces and cucumbers into strips.

Step 1: Cut the tomatoes into bite-sized pieces and slice the cucumber into strips.

Mix all the dressing ingredients and bonito flakes in a bowl.

Step 2: Mix the dressing well, then add the bonito flakes.

Mix in tomatoes and cucumbers and combine everything well.

Step 3: Add the tomatoes and cucumbers, and toss everything together until well combined.

Kurumi's Tips

  • Change up the flavors: Play around with different types of vinegar, oil, and veggies to switch up the taste! For example, try using olive oil and balsamic vinegar for an Italian-ish salad.

What to Serve with This Salad

Because this salad is tangy, sweet, and refreshing, it pairs really well with any oily main dish, like teriyaki chicken, Japanese creamy crab croquette, or Japanese curry.

You can also make a light noodle dish with somen, soba, or udon by simply topping them with this salad for a refreshing summer meal. Add some protein to make it a balanced dish!

Storage Instructions

Store the salad in an airtight container in the refrigerator for up to 2–3 days.

    This is the summer salad you need to make when you want to add a refreshing side to richer, oilier dishes! The freshness cuts through the oiliness perfectly, and the umami from the katsuobushi is sooo good. I hope you love this recipe as much as I do!
