Mexican Street Corn Pasta Salad Recipe with Cotija and Lime

A wooden spoon lifts a serving of creamy pasta salad with rotini, red onions, green peppers, cilantro, crumbled cheese, and sprinkled spices from a large white dish. Two orange pepper mills are visible in the background.

I develop recipes by tasting and adjusting as I go. This Mexican Street Corn Pasta Salad started from that same process: a little more lime, a touch more spice, a bit more cotija, until it felt balanced. The final result is bright, creamy, and smoky—perfect for summer gatherings. Below I’ve organized the steps, ingredients, and tips so you’ll get the same great result at home.

A key rule for any pasta salad is to make the dressing bold. If the dressing tastes balanced on its own, it will likely be muted once combined with pasta and vegetables. I deliberately make this dressing slightly punchy so the flavors hold up after chilling. Read through the whole post for small tips that make a big difference, then follow the method for reliable results.

Mexican Street Corn Pasta Salad — Ingredients

1 pound short, chunky pasta (rotini, radiatori, shells, or cavatappi)
1/2 tablespoon white vinegar
1 cup mayonnaise
1/2 cup sour cream
1 teaspoon chili powder
1/2 teaspoon ground cumin
Salt and freshly ground black pepper, to taste
Juice of 3 limes
1 teaspoon everything-but-the-elote style seasoning (or similar)
Tajín, for sprinkling
5 oz cotija cheese, crumbled (about half a block)
3/4 cup finely chopped red onion
2 bags frozen Southwest-style corn, thawed (about 9.5 oz each)
3 jalapeños, seeded and chopped (adjust heat to taste)
1/4 cup chopped cilantro or parsley

Method

Cook the pasta. Bring a large pot of salted water to a boil. Cook the pasta until al dente according to package directions. Drain and immediately toss the warm pasta with a splash of white vinegar. This brightens the flavor and helps the dressing cling to the noodles.
Brown the corn. In a large skillet, heat 3 tablespoons of butter over medium-high heat. Add the thawed corn and spread it in an even layer. Leave it undisturbed until you hear a light sizzle and start to see charred spots, then stir occasionally until the corn is browned and caramelized. Remove from heat and let cool slightly.
Make the dressing. In a large bowl whisk together the mayonnaise, sour cream, lime juice, chili powder, cumin, everything-style seasoning, and salt and pepper. Taste and adjust—remember the dressing should be a touch bolder than you might usually prefer.
Combine. Add the warm pasta, browned corn, red onion, jalapeño (seeded if you prefer milder heat), most of the cotija, and chopped cilantro to the bowl with the dressing. Toss gently until everything is evenly coated.
Finish and chill. Transfer to a serving bowl, top with the remaining cotija, and sprinkle liberally with Tajín for color and brightness. Refrigerate for at least 30 minutes before serving so the flavors meld.

Melissa’s Tips

Toss warm pasta with a splash of vinegar before rinsing; it enhances the final flavor.
Let the corn sit and brown instead of stirring immediately—those little charred bits add complexity.
Chill the salad for at least 30 minutes so the dressing soaks into the pasta.
Reserve a little cotija, cilantro, and Tajín to sprinkle on top right before serving for the best presentation.
Adjust heat by adding or removing jalapeño seeds, or add extra Tajín if you like more spice.

🤔 Common Questions

What pasta works best?

Short, textured shapes that hold dressing are ideal: rotini, radiatori, shells, cavatappi, ditalini, or bow ties.

Is this spicy?

It’s mildly spicy. Removing jalapeño seeds reduces heat. Leave them in or add extra seasoning if you want more kick.

Can I make this ahead?

Yes. Make it a few hours ahead and chill. For best texture, add any delicate garnishes just before serving.

👝 How to Store Leftovers

Store leftovers in an airtight container in the refrigerator for 3–5 days. The salad holds up well, though the pasta will absorb more dressing over time—stir gently before serving and refresh with a squeeze of lime if needed.
