Easy Marinated Cucumber Tomato Onion Salad Recipe

July 8, 2025

This refreshing cucumber, tomato, and onion salad is super easy to whip up! Just toss fresh veggies with a zesty marinade for a colorful side dish that’ll brighten any meal.

The crunchiness of the cucumbers paired with juicy tomatoes is a match made in heaven. I love making this salad in warm weather—so light and tasty, it’s like a garden party in a bowl! 🌿

Key Ingredients & Substitutions

Cucumbers: I like using English cucumbers because they have fewer seeds and a thinner skin. You can also use regular cucumbers; just peel them if you prefer a milder flavor.

Tomatoes: Ripe, juicy tomatoes are key! Roma or vine-ripened tomatoes work well. If fresh tomatoes are hard to find, canned diced tomatoes in juice can work in a pinch.

Red Onion: Red onions are sweeter and milder, perfect for salads. If you want less sharpness, soak sliced onions in cold water for 10 minutes before adding them!

Olive Oil: Extra virgin olive oil adds great flavor. However, any neutral oil like canola or grapeseed will work if you’re looking for something lighter.

Vinegar: Red wine vinegar gives a nice tang. You can swap it with apple cider vinegar for a different flavor profile or lemon juice for freshness.

How Do I Get the Best Flavor from My Salad?

Marinating the salad is essential to enhance flavors. To ensure every bite is tasty:

  • Mix and coat the vegetables well with the marinade to let each piece absorb the flavors.
  • Let the salad sit in the refrigerator for at least 1 hour. This waiting time is crucial—it’s when the flavors really come together!
  • Before serving, taste the salad. You might want to adjust the salt or vinegar based on your preference!

Enjoy this simple, refreshing salad as a side dish or a light meal, and feel free to customize it with your favorite herbs or other veggies!

Step-by-Step Instructions:

1. Mixing the Vegetables:

Start by dicing the cucumbers and tomatoes into bite-sized pieces, and slice the red onion thinly. Place all these fresh veggies in a large mixing bowl. If you’re using parsley or cilantro, chop it finely and add it to the bowl for an extra burst of flavor.
