Ingredients
- Cucumbers: Choose firm cucumbers for the best crunch Smaller varieties like English or Persian cucumbers have fewer seeds and sweeter flavor
- Tomatoes: Use ripe juicy tomatoes or cherry tomatoes for bright color and flavor Look for tomatoes with a deep red hue and no soft spots
- Sweet onion: Thin slices of sweet onion add a gentle bite and a little sweetness Try to find Vidalia or Walla Walla onions if you can
- Sour cream: Adds a creamy tangy note to the dressing Use full fat for the best texture
- Mayonnaise: Balances the dressing and makes it extra silky Go for a good quality mayo as the flavor really shines here
- Dried dill: Brings classic herby freshness Dried dill gives a concentrated flavor but fresh dill works if you have it
- Garlic powder: Delivers subtle allium flavor without any sharpness Be sure your jar is fresh for the best flavor
- Kosher salt: Season to taste and bring out each vegetable’s best flavor
- Fresh ground black pepper: Adds a gentle bit of heat with every bite
Step-by-Step Instructions

- Prep and Add the Vegetables:
- Slice cucumbers in half lengthwise then thinly slice crosswise for easy bites Cut tomatoes into slim wedges or halve cherry tomatoes Thinly slice the sweet onion Add all vegetables to the bowl of dressing
- Combine the Salad:
- Use a large spatula or serving spoon to gently stir the vegetables into the dressing Gently turn the veggies so they are evenly coated with the creamy mixture Try not to break up the cucumbers or tomatoes Keep mixing until every piece looks glossy
