Fresh tomatoes, cucumbers, onion, and herbs tossed in a light creamy dressing with pasta make a salad that's absolutely irresistible! Creamy Tomato Cucumber Pasta Salad is not only easy to make but it's colorful, cool, and does double duty as a side dish or salad.
Bring a pot of salted water to a boil and add pasta. Cook pasta according to package directions.
While pasta cooks, halve tomatoes, slice the cucumber, and onion. Chop the dill, parsley, and basil. Put all ingredients into a large bowl.
To a small bowl or mason jar, add sour cream, mayonnaise, red wine vinegar, sugar, garlic powder, salt, and pepper. Whisk together or shake to combine.
Drain and rinse the cooked pasta. After cooling for 5 minutes, add it to the bowl with the chopped vegetables and herbs. Pour dressing over and toss to combine. Taste and adjust seasoning. Cover and refrigerate for 1 hour before serving.
