Ingredients

Scale
  • 1 pound rotini pasta
  • 1 pound ground beef
  • 1 packet (1 ounce) taco seasoning mix
  • 1 cup water
  • 1 cup mayonnaise
  • 1/2 cup sour cream
  • 1/4 cup ranch dressing
  • 2 tablespoons lime juice, fresh squeezed
  • 1 teaspoon chili powder
  • 1/2 teaspoon ground cumin
  • 1/2 teaspoon salt
  • 1/4 teaspoon black pepper
  • 1 cup shredded cheddar cheese, sharp
  • 1 cup cherry tomatoes, halved
  • 1 cup black olives, sliced
  • 1/2 cup red onion, finely chopped
  • 1 cup shredded lettuce, iceberg or romaine
  • 1 cup crushed tortilla chips or Doritos for topping

Instructions

  1. Cook the rotini pasta according to package directions until al dente. Drain the pasta and rinse immediately with cold water to stop the cooking process. Set aside.
  2. In a large skillet over medium heat, brown the ground beef. Drain off any excess fat.
  3. Add the taco seasoning mix and water to the cooked beef. Stir well and simmer for 5 to 7 minutes, or until most of the liquid has evaporated. Remove from heat and let the seasoned beef cool completely.
  4. While the beef cools, prepare the dressing. In a medium bowl, whisk together the mayonnaise, sour cream, ranch dressing, lime juice, chili powder, cumin, salt, and pepper until smooth. This is your creamy dressing base.
  5. In a very large bowl, combine the cooled pasta, cooled seasoned beef, shredded cheese, halved cherry tomatoes, sliced black olives, and chopped red onion.
  6. Pour the creamy dressing over the pasta mixture. Fold everything together gently until all ingredients are evenly coated.
  7. Stir in the shredded lettuce last.
  8. Cover the bowl and chill the Taco Pasta Salad in the refrigerator for at least 1 hour before serving. Chilling allows the flavors to blend.
  9. Just before serving, sprinkle the crushed tortilla chips or Doritos over the top for texture. Serve cold.

Notes

  • For a make-ahead meal prep option, keep the crunchy topping separate until serving time to prevent sogginess.
  • If you skip the ground beef, substitute with 1 (15-ounce) can of black beans, rinsed and drained, for a hearty vegetarian pasta salad option.
  • You can substitute the ranch dressing with an equal amount of plain Greek yogurt for a slightly lighter dressing.
