Ingredients for Marinated Cucumber, Onion, and Tomato Salad

The salad calls for a handful of simple, widely available ingredients. Here’s what you’ll need:

• Cucumbers: Offer crispness and freshness; English or regular cucumbers are ideal.
• Tomatoes: Bring juicy sweetness; use ripe, flavorful tomatoes for the best results.
• Onion: Adds sharpness and complexity; red, Vidalia, or yellow onions all work.
• White Vinegar: The backbone of the tangy marinade.
• Olive Oil: Adds richness and helps balance the acidity.
• Sugar: Gives a touch of sweetness to offset the vinegar’s tartness.
• Salt & Ground Black Pepper: Essential for seasoning and depth.

Step-by-Step Preparation Guide

Making this salad couldn’t be more straightforward. Here’s how to do it:

1. Prepare the Dressing: In a large bowl, whisk together the white vinegar, olive oil, sugar, salt, and pepper until well combined.
2. Slice the Vegetables:
   • Peel and thinly slice the cucumbers.
   • Core and cut the tomatoes into wedges or bite-sized pieces.
   • Peel and slice the onion into thin rings or half-moons.
3. Toss Everything Together: Add the cucumbers, tomatoes, and onions to the bowl with the dressing. Toss gently to coat all the vegetables evenly.
4. Marinate the Salad: Cover the bowl and refrigerate for at least 2 hours. This allows the flavors to meld and the vegetables to absorb the tangy-sweet marinade.

Tip: The longer the salad marinates (up to a few hours), the more flavorful and juicy it becomes. For best results, prepare early in the day or even the night before serving.

Tips for the Best Marinated Salad

• Use Fresh, Ripe Vegetables: The better your cucumbers and tomatoes, the more flavorful your salad will be.
• Adjust Seasoning: Taste the salad after it marinates, and add more salt, pepper, or sugar as needed.
• Slice Thinly: Thin slices marinate faster and have a more delicate texture.
• Customize: Add fresh herbs like dill, parsley, or basil, or toss in a pinch of dried Italian seasoning for an extra punch.
• Onion Choice: For a milder flavor, use sweet onions or soak regular onions in ice water for 10 minutes before adding.
• Make Ahead: This salad is ideal for meal-prepping—flavors develop beautifully after hours in the fridge.

• Refrigerate: Always store the salad in a covered container in the refrigerator.
• Longevity: The salad keeps for up to 3–5 days when properly chilled.
• Texture Notes: Cucumbers may soften slightly over time, but the salad remains delicious. The onions mellow out and take on a sweeter, tangier profile. Tomatoes may break down a little but will remain juicy and flavorful.
