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 milk
  • 1 tablespoon chili-lime seasoning (or extra taco seasoning)
  • 1 teaspoon ranch dressing mix (optional, for extra flavor)
  • 1 head iceberg lettuce, shredded
  • 2 cups cherry tomatoes, halved
  • 1 cup shredded cheddar or Mexican blend cheese
  • 1/2 cup chopped red onion
  • 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 well with cold water to cool it down. Set aside.
  2. In a large skillet over medium heat, cook the ground beef until browned. Drain off any excess grease.
  3. Stir the taco seasoning mix and water into the cooked ground beef. Bring to a simmer and cook for 5 to 7 minutes, stirring occasionally, until the sauce has thickened slightly. Remove from heat and let the beef cool completely.
  4. While the beef cools, prepare the creamy dressing. In a medium bowl, whisk together the mayonnaise, sour cream, milk, chili-lime seasoning, and optional ranch mix until smooth.
  5. In a very large bowl, combine the cooled pasta, cooled seasoned ground beef, shredded lettuce, halved cherry tomatoes, shredded cheese, and chopped red onion.
  6. Pour the creamy dressing over the pasta mixture. Toss gently until all ingredients are evenly coated.
  7. Cover the bowl and chill the taco pasta salad in the refrigerator for at least 1 hour before serving. This allows the flavors to blend.
  8. Just before serving, sprinkle the crushed tortilla chips or Doritos over the top for crunch. Serve this cold pasta salad chilled.

Notes

  • You can easily make this taco pasta salad recipe ahead of time. Prepare the entire salad, but keep the crunchy topping separate until serving to prevent sogginess.
  • For a lighter dressing, substitute half the mayonnaise with plain Greek yogurt.
  • This recipe works well for meal prep; store individual portions in airtight containers for quick lunch ideas throughout the week.
