Ingredients

Scale
  • 12 ounces short pasta, like rotini or fusilli
  • 2 (5-ounce) cans solid white albacore tuna in water, drained well
  • 1 cup diced celery
  • 3/4 cup diced red onion
  • 1 cup halved cherry or grape tomatoes
  • 1/3 cup chopped fresh dill
  • 1/4 cup chopped fresh parsley
  • 3/4 cup mayonnaise
  • 1/3 cup sour cream
  • 2 tablespoons Dijon mustard
  • 2 tablespoons fresh lemon juice
  • 1 teaspoon lemon zest
  • 1 teaspoon garlic powder
  • 1/2 teaspoon onion powder
  • Salt and freshly ground black pepper to taste

Instructions

  1. Cook pasta in salted boiling water until al dente. Drain and rinse immediately with cold water.
  2. Whisk mayonnaise, sour cream, Dijon mustard, lemon juice, lemon zest, garlic powder, onion powder, salt, and pepper in a bowl to make the dressing.
  3. In a large bowl, combine cooled pasta, drained tuna, celery, red onion, tomatoes, dill, and parsley.
  4. Pour the dressing over the pasta mixture and fold gently until everything is evenly coated.
  5. Cover and refrigerate for at least 1 hour before serving to allow flavors to meld.

Notes

For best texture, do not overcook the pasta and ensure the tuna is well-drained. The salad keeps for 3-4 days in the fridge. For a lighter version, substitute Greek yogurt for sour cream.
