Heirloom Tomato Salad With Shiso and Shallots

The first time I tasted an heirloom tomato salad like this, it was at a small farm-to-table restaurant nestled in the Sonoma Valley. The burst of sweet, tangy, and savory flavors transported me instantly back to my grandmother’s garden, where vibrant tomatoes in every shade imaginable grew abundantly. The aroma of fresh herbs mingled with the sun-warmed earth, creating a sensory symphony that has stayed with me ever since. This salad attempts to recapture that magic, celebrating the simple beauty of peak-season produce.

Recipe Overview

• Prep Time: 15 minutes
• Cook Time: 0 minutes
• Total Time: 15 minutes
• Servings: 4-6
• Yield: 1 salad
• Dietary Type: Vegetarian, Gluten-Free

Ingredients

• 3 lbs very ripe assorted heirloom tomatoes
• 2 cups small cherry tomatoes
• Fine sea salt
• ½ cup shallot, for dressing
• ¾ cup loosely packed shredded fresh green shiso leaf (about 1 bunch)

Shallot dressing

• ½ cup finely chopped shallot
• 1 tablespoon white wine vinegar
• ¾ teaspoon kosher salt
• ¼ cup fresh lemon juice
• ½ teaspoon sugar
• 1 ½ teaspoons sesame oil
• ½ cup corn oil

Equipment Needed

• Large bowl
• Sharp knife
• Cutting board
• Whisk (optional, for dressing)

Instructions

1. First, prepare the shallot dressing. In a small bowl, combine the ½ cup finely chopped shallot, 1 tablespoon white wine vinegar, ¾ teaspoon kosher salt, ¼ cup fresh lemon juice, ½ teaspoon sugar, 1 ½ teaspoons sesame oil, and ½ cup corn oil. Whisk vigorously until the dressing is emulsified. You can also use a small blender to create a smoother, more integrated dressing. Set aside.

2. Prepare the tomatoes. Cut the 3 lbs of heirloom tomatoes into small, chunky wedges. If the tomatoes are very large, you may need to cut them into smaller pieces. For the 2 cups of cherry tomatoes, halve them, unless they are very small. In that case, leave them whole.

3. In a large bowl, season the tomatoes with fine sea salt. Be generous, as the salt will help draw out the tomatoes’ natural sweetness. Also add freshly ground black pepper to taste.

4. Pour the shallot dressing over the seasoned tomatoes in the bowl. Gently toss the tomatoes to ensure they are evenly coated with the dressing.

5. Let the tomatoes marinate for 5 minutes. This allows the flavors to meld together and the tomatoes to absorb the dressing. Avoid marinating for too long, as the tomatoes can become overly soft.

6. Just before serving, gently toss the tomatoes with the ¾ cup loosely packed shredded fresh green shiso leaves. Be careful not to bruise the delicate shiso leaves.

7. Serve the heirloom tomato salad immediately, drizzling the remaining juices from the bowl over the top. The juices contain the essence of the salad and should not be discarded.

Expert Tips & Tricks

• Tomato Selection is Key: Choose heirloom tomatoes that are firm but yield slightly to gentle pressure. A mix of colors and varieties will add visual appeal and complexity of flavor.
• Salt Strategically: Seasoning the tomatoes with salt before adding the dressing helps to draw out their natural sweetness and enhance their flavor.
• Shiso Substitutes: If you can’t find shiso, try using fresh basil or mint. While the flavor profile will be different, they still provide a lovely herbaceous note.
• Chill the Tomatoes (Slightly): For an extra refreshing salad, briefly chill the tomatoes (about 15 minutes in the refrigerator) before assembling the salad. However, avoid over-chilling, as this can dull their flavor.
• Dressing Adjustment: Taste the dressing before tossing it with the tomatoes and adjust the seasoning as needed. You may want to add a pinch more sugar or a squeeze of lemon juice depending on the acidity of the tomatoes.
• Make Ahead (Partially): You can prepare the dressing up to a day in advance and store it in the refrigerator. However, it’s best to assemble the salad just before serving to prevent the tomatoes from becoming soggy.
• Elevate with Cheese: A sprinkle of crumbled feta or goat cheese adds a creamy, tangy element that complements the sweetness of the tomatoes and the herbaceousness of the shiso.

Serving & Storage Suggestions

Serve the heirloom tomato salad immediately after tossing with the shiso leaves to prevent the herbs from wilting. The salad is best enjoyed fresh, as the tomatoes will release their juices over time and become less firm.

If you have leftovers, store them in an airtight container in the refrigerator. However, be aware that the tomatoes will continue to release juices, so the salad will be somewhat wetter the next day. It’s best to consume leftovers within 1-2 days. The salad is not suitable for freezing.

This salad pairs well with grilled fish, chicken, or tofu. It’s also a great addition to a summer barbecue or picnic. Consider serving it alongside crusty bread to soak up the flavorful juices. A chilled glass of rosé or Sauvignon Blanc complements the salad beautifully.
