Why You’ll Love This Salad
Some salads are filling, while others are refreshing. This recipe delivers both. The cool cucumbers add plenty of crunch, ripe tomatoes provide natural sweetness, and the creamy garlic dressing ties everything together without feeling heavy.
Because it uses only a handful of ingredients, each one really shines. During tomato season, this salad becomes even more flavorful thanks to garden-fresh produce.
Whether you’re following a low-carb lifestyle or simply looking for an easy vegetable side dish, this recipe fits the bill. It comes together in minutes, requires no cooking, and tastes even better with freshly picked vegetables.
If you’ve ever needed a last-minute side for grilled burgers, steak, chicken, or seafood, this salad is an excellent choice.
Step-by-Step Cooking Guide
Step 1: Prepare the Vegetables
Wash the tomatoes and cucumbers thoroughly before slicing.
Cut the tomatoes into evenly sized pieces so they hold their shape after mixing. Slice the cucumber into bite-sized half-moons, and thinly slice the onion so it blends smoothly with the dressing.
Tip: If your tomatoes are especially juicy, gently remove some of the seeds before mixing to help prevent excess liquid in the bowl.
Step 2: Make the Creamy Garlic Dressing
In a separate bowl, combine:
- Sour cream
- Mayonnaise
- Pressed garlic
- Black pepper
Whisk until completely smooth.
The dressing should be creamy enough to coat every vegetable without becoming too thick.
Tip: Let the dressing rest for about five minutes before using. This gives the garlic time to infuse the mixture with even more flavor.
Step 3: Toss Everything Together
Place the chopped vegetables into a large mixing bowl.
Pour the dressing over the vegetables and gently fold everything together using a large spoon or silicone spatula.
Avoid overmixing, as ripe tomatoes can break apart.
Tip: Toss gently from the bottom of the bowl to evenly coat every cucumber and tomato.
Step 4: Season Just Before Serving
Finish with salt immediately before serving.
Adding salt too early pulls moisture from the vegetables, making the dressing thinner over time.
A sprinkle of fresh dill or parsley adds freshness and beautiful color.
Ingredient Details and Substitution Tips
Tomatoes
Choose ripe, firm tomatoes that feel heavy for their size. Roma, vine-ripened, heirloom, beefsteak, and cherry tomatoes all work well.
If using cherry tomatoes, simply slice them in half.
Cucumbers
English cucumbers are ideal because they have thin skin and very few seeds.
Garden cucumbers also work well but may benefit from peeling if the skin is thick.
Persian cucumbers are another excellent choice thanks to their crisp texture.
Onion
Yellow onions provide a mild sweetness.
Red onions create a sharper flavor and add vibrant color.
White onions offer a cleaner, brighter bite.
For a milder onion flavor, soak the slices in cold water for about 10 minutes before adding them to the salad.
Sour Cream
Full-fat sour cream creates the richest dressing while keeping carbohydrates relatively low.
If you prefer a lighter version, full-fat plain Greek yogurt is a great substitute that also increases the protein content slightly.
Mayonnaise
Only a small amount is needed, but it adds richness and helps create a silky dressing.
You can replace it with:
- Extra sour cream
- Mashed avocado
- Plain Greek yogurt
Each option changes the flavor slightly while maintaining a creamy texture.
Garlic
Fresh garlic gives the dressing its signature flavor.
Avoid garlic powder if possible, as fresh garlic creates a brighter, more aromatic dressing.
One clove is perfect for a balanced flavor, while two cloves work well for garlic lovers.
Equipment Alternatives
No garlic press?
Simply mince the garlic as finely as possible using a sharp knife.
No large mixing bowl?
Mix the vegetables in a serving bowl to save dishes.
No whisk?
A fork works perfectly for blending the dressing.
Recipe Variations and Serving Suggestions
One of the best things about this salad is how easy it is to customize. The creamy dressing complements a variety of fresh vegetables, herbs, and proteins, making it a versatile recipe you’ll come back to throughout the year.
Flavor Variations
Add Fresh Herbs
Fresh herbs instantly brighten the salad.
- 2 tablespoons chopped fresh dill for a classic flavor

Add More Vegetables
For extra crunch and color, try adding:
- ½ cup sliced radishes

Add Cheese
If you’re looking for an even richer salad, mix in one of these cheeses:
- ½ cup crumbled feta
- ½ cup fresh mozzarella pearls
- ¼ cup grated Parmesan
- ⅓ cup shredded sharp cheddar
These cheeses are all relatively low in carbohydrates and complement the creamy dressing beautifully.
Boost the Protein

Great options include:
- Grilled chicken breast

- Pan-seared salmon

These additions keep the salad low in carbs while making it hearty enough for lunch or dinner.

Serve it alongside:
- Grilled chicken thighs
- Garlic butter steak
- Baked salmon
- Pork chops
- Beef kebabs

For presentation, transfer the salad to a chilled serving bowl and garnish with freshly cracked black pepper and chopped dill just before serving.
Storage and Make-Ahead Information
How to Store
Store leftovers in an airtight container in the refrigerator for up to 2 days.
Because cucumbers and tomatoes naturally release moisture, the dressing may become thinner over time.
The salad is freshest on the day it’s prepared.
Reheating
No reheating is needed. This salad is meant to be served cold.
If the dressing separates slightly after refrigeration, gently stir before serving.
Make-Ahead Tips
You can prepare the components ahead of time to save time later.
- Chop the vegetables up to one day in advance.
- Store the vegetables and dressing separately in the refrigerator.
- Toss everything together just before serving.
This keeps the vegetables crisp and prevents the dressing from becoming watery.
Freezing
Freezing is not recommended.
Fresh cucumbers and tomatoes lose their texture after thawing, resulting in a watery salad.

Frequently Asked Questions
Can I make this salad ahead of time?
Yes. For the best texture, prepare the vegetables and dressing separately and combine them just before serving.
Can I use cherry tomatoes?
Absolutely. Cherry or grape tomatoes are naturally sweet and require very little preparation. Simply cut them in half before adding them to the salad.
What cucumbers work best?
English cucumbers are ideal because they have tender skin and fewer seeds. Persian cucumbers are another excellent option.
Can I replace the sour cream?
Yes. Plain full-fat Greek yogurt is an excellent substitute that creates a slightly tangier dressing while adding extra protein.
Why did my dressing become watery?
Salt causes tomatoes and cucumbers to release moisture. That’s why it’s best to season the salad immediately before serving.
Can I use dried herbs?
Fresh herbs provide the best flavor, but dried dill or parsley can be used if needed. Start with about one-third of the amount called for with fresh herbs.
Is this salad keto-friendly?
Yes. The ingredients are naturally low in carbohydrates and fit well into most keto eating plans.
What proteins pair best with this salad?
Grilled chicken, steak, salmon, shrimp, turkey, pork chops, and hard-boiled eggs all pair wonderfully with the creamy dressing.
Can I omit the mayonnaise?
Yes. Replace it with additional sour cream or plain Greek yogurt if you prefer.
How can I make the salad more filling?
Add grilled chicken, sliced steak, shrimp, avocado, bacon, or crumbled feta cheese to transform it into a complete meal.
