🧾 Ingredients for Keto Cucumber Tomato Salad

For the Salad:

  • 2 large cucumbers (English or Persian), sliced or diced

  • 1½ cups cherry tomatoes, halved

  • ¼ cup red onion, thinly sliced (optional for extra flavor)

  • ¼ cup chopped fresh parsley or dill

  • Salt and black pepper to taste

For the Keto Vinaigrette:

  • 3 tablespoons extra virgin olive oil

  • 1 tablespoon apple cider vinegar or lemon juice

  • ½ teaspoon Dijon mustard (ensure no added sugars)

🍽️ How to Make Keto Cucumber Tomato Salad

Step 1 – Prep the Vegetables

Wash and dry your cucumbers and tomatoes. Slice cucumbers into rounds or half-moons and halve the tomatoes. Thinly slice the red onion if using, and chop the herbs.

Step 2 – Make the Dressing

In a small bowl or mason jar, whisk together olive oil, vinegar (or lemon juice), mustard, garlic, and seasonings until well combined.

Pro Tip: Let the dressing sit for 5 minutes to allow flavors to develop, especially if using fresh garlic.

Step 3 – Combine and Toss

Add the chopped vegetables and herbs into a large bowl. Pour the vinaigrette over the salad and toss gently to coat. Taste and adjust seasoning as needed.

❓FAQs About Keto Cucumber Tomato Salad

Yes—in moderation. Cherry tomatoes contain ~3–4g net carbs per half cup. Used in the right quantity, they add flavor without carb overload.

Absolutely. Cucumbers are low in carbs, high in fiber, and contain 95% water—ideal for hydration and gut health.

Can I make this salad ahead of time?

Yes! Just store the dressing separately and add it when ready to eat. This helps the veggies stay crisp and flavorful.

Is Dijon mustard keto?

Most Dijon mustard is keto-safe, but check the label to ensure there’s no added sugar or wine.
