Creating the Mexican Street Corn Pasta Salad is simple if you follow these easy steps:

1. Cook the Pasta: Boil a large pot of water and cook the pasta according to package instructions until al dente. Drain and rinse under cold water to stop the cooking process.

2. Prepare the Corn: If using fresh corn, grill or sauté it until it’s slightly charred. For frozen corn, simply thaw it in hot water and drain.

3. Mix the Vegetables: In a large bowl, combine the cooked pasta, corn, cherry tomatoes, red onion, and cilantro.

4. Make the Dressing: In a separate bowl, whisk together the mayonnaise, sour cream, lime juice, chili powder, garlic powder, salt, and pepper until smooth.

5. Combine: Pour the dressing over the pasta salad mixture and gently toss until everything is coated well.

6. Add the Cheese: Sprinkle the cotija cheese on top and mix lightly to incorporate.

7. Chill: Cover the salad and refrigerate for at least 30 minutes to let the flavors meld together.

8. Serve: Toss again before serving, adjusting seasoning if necessary.

These straightforward steps will guide you in crafting this incredible pasta salad swiftly and easily.
