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

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:
- 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.
- 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.
- 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.
- Season the Mixture: Add salt, black pepper, and garlic powder to the marinade. Stir again to blend the flavors.
- Combine Everything: Pour the marinade over the vegetables. Use clean hands or a large spoon to gently toss until everything is coated well.
- Add Fresh Dill: If using, sprinkle chopped dill over the top. This herb enhances the salad’s brightness and gives it a lovely aroma.
- 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.
- 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.
