Refreshing Salad for Every Meal

Whether you’re having grilled meat, a sandwich, or rice dishes, this salad fits right in. The cool cucumber and zingy vinegar make each bite feel fresh and light. It’s a great way to balance heavier meals like herbed baked chicken, stuffed zucchini boats, curry chicken, enchilada, or grilled stuffed bell peppers.

Simple Salad Recipe

Making a simple salad is the best because it’s quick, fresh, and doesn’t need much effort. With just a few ingredients, you can put together something clean, colorful, and full of flavor. It’s also easy to change it up, use whatever veggies you have and dress it how you like, no stress involved.

Recipe You Can Make Ahead

FULL INSTRUCTIONS WITH STEPS FOR THE BEST CUCUMBER SALAD RECIPE

First Step: Prepare Salad Ingredients

Gather everything you’ll need for the recipe: cucumbers, red onion, apple cider vinegar, honey or agave, sea salt, fresh dill, and black pepper. Make sure your cucumbers and onions are rinsed and ready to slice. Grab a medium or large salad bowl for tossing everything together.

Second Step: Chop the Ingredients

Finely slice the cucumbers into thin rounds and do the same with the red onion. For the best texture, try to keep the slices uniform so they marinate evenly. Chop the fresh dill and set a little extra aside if you want to garnish the salad later.

Third Step: Place the Cucumber and Onion

Add the sliced cucumbers and red onions into your salad bowl. Drizzle in the apple cider vinegar, then add honey (or agave) and sea salt. Gently toss everything together, making sure the veggies are well coated without bruising them.

Fourth Step: Add in the Rest

Let the mixture chill in the fridge for at least 20 minutes so the flavors can develop. After marinating, drain off the excess liquid and transfer the vegetables to a serving platter. Finish with a sprinkle of chopped dill and a few grinds of black pepper before serving.

TRICKS AND TIPS:

  • Use thin slices for better flavor soak. Thinly slicing the cucumbers and onions helps them absorb the marinade faster and more evenly. It also gives the salad a nice texture and look.
  • Let it chill for at least 20 minutes. Giving the salad time in the fridge lets the vinegar and seasonings blend into the vegetables. The longer it sits, the better the flavor gets.
  • Use seedless or English cucumbers if possible. They have thinner skin and fewer seeds, which makes for a crunchier, less watery salad. If using regular cucumbers, peeling and seeding them can help.
  • Adjust the sweetness and tang to taste. Some like it a bit sweeter, others more tangy, taste the marinade and tweak with a little honey, sugar, or more vinegar before adding it in. Everyone’s perfect salad balance is a little different.
