    Garden Fresh

    There are so many things to love about this side dish! It's perfect for summer because this cucumber tomato salad incorporates fresh-picked, garden veggies and herbs — some of summer's sweetest little treasures.

    However, we are lucky enough to have access to fresh vegetables and herbs year-round so you can make this veggie side dish any time of the year.

    Easy and Delicious

    This herbed cucumber and tomato salad is something I look forward to as soon as gardening season hits. It's so easy and healthy and DELICIOUS!!!

    Cucumber Tomato Onion Salad

    Summer Side Dish

    This fresh side dish goes with just about any meal. I love to throw this together for weeknight meals. I always make a big batch because it stores well for a few days in the fridge.

    ☆ Ingredients You'll Need ☆

    This salad is super simple. You just start with fresh veggies and then toss them in a quick and simple homemade dressing.

    Here's everything you need:

    Cucumber Tomato Salad Ingredients
    • Cucumbers. You can use regular cucumbers or English cucumbers which are small and are more dry (smaller, less watery seeds).
    • Tomatoes. Roma or grape tomatoes work best as they aren't super watery.
    • Onion. You can go with white, yellow or red onion. Red onions are a bit more mild, then white, then yellow are the strongest.

    Then the dressing!

    For the dressing you'll mix together:

    • Honey. Or you can use agave nectar for a more mild flavor.
    • Fresh mint. Grow your own or you can buy from the store.
    • Fresh basil. Again, homegrown or you can buy but fresh is best.
    • Vinegar. Apple cider vinegar is a great option but you can also use white vinegar or red wine vinegar.
    • Oil. You can use olive oil, avocado oil, or grape seed oil. These all have a nice flavor.
    • Lemon juice. Fresh squeezed is best since you'll get more flavor but you can also use bottle lemon juice if that's more convenient.
    • Salt and pepper. Add this to taste!

    The combination of basil and mint in this homemade honey-lemon vinaigrette is what really makes this cucumber and tomato dish really come together! It's fresh and bright with a hint or sweet and tart.

    This vinaigrette dressing is a great little back-pocket recipe of mine that goes well on traditional salads and pasta salad too.

    Check out my orzo pasta salad that incorporate this dressing if you're a fan.

    ☆ How to Make this Recipe ☆

    If you find yourself with so many tomatoes and cucumbers you don't know what to do with them all, and you're not really wanting to go to great lengths to turn them into a culinary masterpiece... Well then, this very simple recipe is for you!

    Here are the basic steps, the full recipe is below:

    How to Make Cucumber Tomato Salad
    1. Cut up your veggies, peel as needed.
    2. Whisk together ingredients for dressing.
    3. Toss cucumber, tomatoes, onions and herbs with dressing.

    That's it! So simple.

    ☆ Tips & FAQs ☆

    How to Store Leftovers

    Storing this Salad
    This salad stores well in the fridge for up to 3 day. Store in an air-tight container.
    I do not recommend freezing. The vegetables will loose their crunchy texture.
    Storing Dressing
    One of my favorite ways to make and store homemade dressings is using a Mason jar. I just add all the ingredients, shake it up and then pour. I bought some pour caps so that I can make a big batch of dressing and pour out just what I need, then store the rest. So if you want to make extra dressing, this is a great way to store it.

    What kind of onions work best for this salad?

    Red onions are a popular choice for their mild flavor and vibrant color, but white onions, or even thinly sliced shallots also work well.

    Can I make the vinaigrette ahead of time?

    Yes! Homemade vinaigrette can be made ahead and stored in the fridge for up to a week. Just give it a good shake before using.

    How do I keep cucumbers from getting soggy?

    To keep cucumbers crisp, you can slice and lightly salt them, then let them sit for 10–15 minutes. Pat dry with a paper towel before adding to the salad.

    Can I add other ingredients to this salad?

    Absolutely! Try adding feta cheese, avocado, chickpeas, or fresh herbs like basil or dill to mix things up. I also like to add leftover corn scraped off the cob.
