This Fiesta Pasta Salad is the ultimate crowd-pleaser for BBQs, potlucks, meal prep, and summer dinners. It is colorful, creamy, zesty, and loaded with cavatappi or rotini pasta, black beans, Mexicorn, tomatoes, green onions, and creamy avocado.
The twist that makes this pasta salad so good is the dressing. Instead of just crumbling queso fresco over the top, the cheese gets whisked directly into a lime and red wine vinaigrette. It creates a rich, creamy, slightly chunky dressing that clings to every piece of pasta and pulls all the beans, corn, and crisp vegetables into every bite.

Ingredients
Pasta Base
- 12–16 ounces dry cavatappi or rotini pasta
Fiesta Mix
- 2 large avocados, chopped
- 3 plum tomatoes, chopped
- 1 bunch green onions, chopped
- 1 can black beans, rinsed and drained
- 1 can Mexicorn, drained
Creamy Queso Fresco Dressing
- 1 cup crumbled queso fresco
- 1/4 cup red wine vinegar
- Juice of 1 lime
- 1/4 cup plus 2 tablespoons olive oil or avocado oil
- Garlic cloves, minced
- 1 teaspoon cumin
- 1 teaspoon chili powder
- 1/2 teaspoon salt
- 1/2 teaspoon black pepper
- Hot sauce, to taste
- 2 tablespoons fresh cilantro, chopped
How to Make Fiesta Pasta Salad
- Cook the pasta. Boil the pasta until al dente. Drain and immediately rinse with cold water to stop the cooking and remove sticky starches.
- Make the dressing. In a bowl, whisk together the red wine vinegar, lime juice, oil, minced garlic, cumin, chili powder, salt, pepper, hot sauce, and cilantro.
- Add the queso fresco. Vigorously whisk in the crumbled queso fresco until the dressing becomes thick, creamy, and slightly chunky.
- Build the salad. In a large bowl, combine the cold pasta, chopped tomatoes, green onions, black beans, and Mexicorn.
- Toss with dressing. Pour the queso fresco vinaigrette over the top and toss until everything is evenly coated.
- Add avocado last. Gently fold in the chopped avocados at the end so they stay intact and do not get mashed.
- Cover tightly and refrigerate for at least 1 hour before serving.
Recipe Tips
- Toss the avocado with lime. Tossing avocado chunks in fresh lime juice before adding them to the salad helps keep them bright green.
- Rinse the pasta. For this chilled pasta salad, rinsing cools the pasta quickly and helps prevent stickiness.
- Whisk the queso fresco well. The cheese should break into the vinaigrette and make the dressing creamy while still slightly textured.
- Add avocado gently. Fold it in at the end so the pieces stay pretty and do not mash into the salad.
Make-Ahead and Storage
This pasta salad can be made a few hours ahead and chilled until ready to serve. For the freshest avocado texture, add the avocado closer to serving time or toss it with lime juice before folding it into the salad.
Store leftovers in an airtight container in the refrigerator for up to 2 days. The avocado may soften slightly as it sits, but the pasta will continue soaking up the creamy queso fresco dressing.
Serving Ideas
Serve Fiesta Pasta Salad with grilled chicken, steak, shrimp, tacos, burgers, hot dogs, barbecue, fajitas, or chips and salsa. It also makes a fun vegetarian main dish for lunch or meal prep.
