This Southwestern Pasta Salad has become my go-to dish for potlucks and summer gatherings, combining vibrant textures and flavors in every colorful bite. The zesty ranch-taco dressing transforms familiar ingredients into something special that always has guests asking for the recipe.
I first created this recipe for a neighborhood block party three summers ago. It disappeared faster than anything else on the table, and now my family requests it weekly during hot weather months. The combination of creamy dressing with crunchy vegetables and hearty beans creates that perfect balance of textures.
Ingredients
- Rotini pasta: Provides the perfect shape for catching all the dressing and small ingredients in its spirals
- Red bell pepper: Adds sweet crunch and vibrant color to brighten the dish
- Green or yellow bell pepper: Creates color contrast and additional fresh flavor
- Cherry tomatoes: Bring juicy bursts of acidity that balance the creamy dressing
- Corn: Delivers sweet pops of flavor and sunny color throughout the salad
- Black beans: Offer protein and hearty texture making this salad more substantial
- Fresh cilantro: Contributes that distinctive southwestern flavor that elevates the entire dish
- Green onions: Provide mild onion flavor without overpowering the other ingredients
- Mayonnaise: Creates the creamy base for the dressing while adding richness
- Greek yogurt: Lightens the dressing while maintaining creaminess and adding protein
- Ranch seasoning mix: Infuses the dressing with herbs and savory notes
- Taco seasoning: Brings the southwestern flair with cumin, chili, and garlic notes
Step-by-Step Instructions
- Cook the Pasta:
- Bring a large pot of salted water to a rolling boil. Add rotini and cook according to package directions until al dente usually 8 to 10 minutes. Be careful not to overcook as the pasta will continue to absorb liquid from the dressing. Once done drain thoroughly.
- Cool the Pasta:
- Immediately run the cooked pasta under cold water tossing gently to stop the cooking process and rinse away excess starch. This prevents the pasta from becoming sticky and helps it maintain its shape. Let it drain completely in a colander for about 5 minutes.
- Prepare the Vegetables:
- While the pasta cooks and cools dice the bell peppers into small uniform pieces about 1/4 inch in size. Halve or quarter the cherry tomatoes depending on their size. Chop the cilantro finely discarding the stems. Slice green onions thinly including both white and green parts.
- Assemble the Salad:
- In your largest mixing bowl combine the cooled pasta with all prepared vegetables, black beans, corn, cilantro, and green onions. Gently fold everything together with a rubber spatula to distribute ingredients evenly without breaking the pasta.
- Mix the Dressing:
- In a medium bowl whisk together the mayonnaise, Greek yogurt, ranch seasoning, and taco seasoning until completely smooth and well blended. The dressing should have a thick pourable consistency that will cling to the pasta and vegetables.
- Combine and Finish:
- Pour the prepared dressing over the pasta mixture and gently fold until everything is evenly coated. Take your time with this step to ensure the dressing reaches all components without crushing the tomatoes or breaking the pasta.

The secret to this salad's addictive quality is the combination of ranch and taco seasonings. I discovered this flavor pairing by accident when I ran short on ranch mix one day and supplemented with taco seasoning from my pantry. My husband declared it the best pasta salad he'd ever tasted, and I've made it this way ever since.
