Serving Suggestions:

Pro Tips for the Best Marinated Cucumbers, Onions, and Tomatoes:

  1. Use Ripe Tomatoes: Pick firm, ripe tomatoes that can hold their shape. Too soft, and they’ll fall apart in the marinade.
  2. Thin Slices Work Best: Thinly slicing the cucumbers and onions helps them soak up flavor faster and more evenly.
  3. Let It Marinate: Don’t rush the chilling time. Two hours is the minimum, but overnight is even better.
  4. Optional Fresh Dill: Add fresh dill for a bright herbal twist—it’s optional but highly recommended for extra flavor.
  5. Toss Before Serving: Always give the salad a quick toss before serving to mix the juices and refresh the flavor.

Marinated Cucumbers, Onions, and Tomatoes Recipe:

  • Preparation time: 15 minutes
  • Chilling time: 2 hours
  • Servings: 6
  • Equipment: Sharp knife, large mixing bowl, whisk or spoon, airtight container or plastic wrap

This Marinated Cucumbers, Onions, and Tomatoes recipe is a delicious way to use seasonal produce while keeping things simple, light, and flavorful.

Ingredients:

  • 2 large cucumbers, thinly sliced
  • 1 medium red onion, thinly sliced
  • 4 ripe tomatoes, cut into wedges
  • ½ cup apple cider vinegar
  • ¼ cup water
  • ¼ cup granulated sugar
  • 1 teaspoon salt
  • ½ teaspoon freshly ground black pepper
  • ¼ teaspoon garlic powder
  • ¼ cup chopped fresh dill (optional)

Directions:

  1. Prep the Vegetables: Start by slicing the cucumbers and placing them in a large bowl. If you prefer, peel them first. Keep the slices uniform for even marinating.
  2. Add the Onion and Tomatoes: Slice the red onion thinly and cut the tomatoes into wedges. If the tomatoes are overly juicy, remove a few seeds to prevent a watery salad. Add everything to the same bowl.
  3. Mix the Marinade: In a separate bowl or large measuring cup, combine the apple cider vinegar, water, and sugar. Stir until the sugar is completely dissolved.
  4. Season the Mixture: Add salt, black pepper, and garlic powder to the marinade. Stir again to blend the flavors.
  5. Combine Everything: Pour the marinade over the vegetables. Use clean hands or a large spoon to gently toss until everything is coated well.
  6. Add Fresh Dill: If using, sprinkle chopped dill over the top. This herb enhances the salad’s brightness and gives it a lovely aroma.
  7. Chill and Marinate: Cover the bowl with plastic wrap or transfer to a sealed container. Refrigerate for at least 2 hours to allow the flavors to soak in.
  8. Toss and Taste: Before serving, toss the salad again and taste. Adjust the salt or pepper if needed, then serve cold for the most refreshing flavor.

Ready to Relish!

Storage Solutions:

This salad keeps well in the fridge for up to 3 days. Store it in an airtight container, and give it a stir before each serving.
