Ever stand at a summer barbecue and wonder why plain grilled corn seems so boring compared to what street vendors make? That smoky, spicy, cheesy corn from Mexican street carts has a secret, and it’s easier to make at home than most people think. The combination of charred kernels, tangy lime mayo, and salty cotija cheese turns regular corn into something people actually fight over at cookouts.
Getting the corn ready makes all the difference
Most people throw raw corn directly on the grill and wonder why it takes forever to cook through. The smarter move involves boiling the corn for about five minutes first. This precooking step means the corn gets tender all the way through, and the grill time focuses purely on getting those beautiful charred spots. Nobody wants to bite into corn that’s burnt on the outside but still crunchy inside.
Shucking the corn completely before grilling gives the kernels direct contact with the hot grates. Some recipes suggest grilling corn in the husk, but that just steams it instead of creating the caramelized, slightly blackened kernels that make this dish special. Pat the boiled corn dry with paper towels before hitting the grill. Wet corn won’t char properly and just creates a mess of steam and smoke. Getting these basics right sets up everything else for success.
The spicy lime mayo needs more than just those three things
The sauce that coats this corn packs way more punch than regular mayonnaise mixed with lime juice. Mixing in sour cream adds tanginess and makes the sauce lighter, so it spreads easier on the hot corn. Ground ancho chile powder brings smoky heat without being too aggressive, while smoked paprika deepens that charred taste even more. Fresh lime zest adds a bright citrus note that regular lime juice alone can’t provide.
Whisking everything together until completely smooth prevents clumps of spices that taste bitter. Some people skip the sour cream and use all mayo, but that creates a heavier coating that can feel greasy. The half-and-half combination hits the right balance between rich and refreshing. Making this sauce ahead and keeping it in the fridge actually improves it, since the spices have time to bloom and distribute evenly through the creamy base.
Cotija cheese isn’t the same as parmesan or feta
Cotija comes from Mexico and has a crumbly texture similar to feta but without the same sour taste. This aged cheese stays salty and mild, which complements the spicy mayo instead of competing with it. Most grocery stores stock cotija in the specialty cheese section, often near the Mexican ingredients. The cheese doesn’t melt like mozzarella or cheddar, which works perfectly here since melted cheese would just slide off the corn.
Crumbling the cotija by hand creates different sized pieces that stick to the mayo coating in interesting ways. Some recipes suggest using parmesan as a substitute, and while it works in a pinch, parmesan has a sharper, nuttier taste that changes the whole profile. Feta can substitute too, but its tanginess adds another layer that might clash with the lime. Fresh cotija from the refrigerated section tastes better than the pre-crumbled stuff in plastic containers, which often includes anti-caking agents that affect the texture.
Charcoal grills work better than gas for this recipe
The smoke from charcoal adds another dimension that gas grills can’t replicate. Setting up a hot fire with the coals piled high creates intense direct heat that caramelizes the corn sugars quickly. Those dark brown and slightly black spots aren’t burning, they’re where the natural sugars in the corn turn into something rich and complex. Gas grills work fine if that’s what’s available, just crank the heat to high and give the corn a few extra minutes.
Turning the corn every minute or two ensures even charring on all sides. Using tongs makes this easier than trying to roll the corn with your hands near the hot grates. The total grill time runs about eight to ten minutes after the corn has been boiled. Watch for kernels that start to pop and turn golden brown with black edges. Pulling the corn off too early means missing out on that smoky sweetness, while leaving it too long creates bitter burnt spots that overpower everything else.
Brushing versus rolling the corn in toppings matters
Street vendors often roll the corn in a shallow dish of mayo and toppings, but that method wastes a ton of sauce. Using a pastry brush or silicone brush lets you control exactly how much coating goes on each ear. Brush the mayo mixture on while the corn is still hot off the grill, so the heat slightly melts everything into the crevices between kernels. Going heavy on the sauce might seem like a good idea, but it just drips off and makes a mess.
After brushing on the spicy mayo, sprinkle the cotija cheese generously over each ear while everything’s still warm. The residual heat softens the cheese slightly without fully melting it, helping it stick better. Adding a final dusting of extra ancho chile powder and a squeeze of fresh lime juice right before serving brightens everything up. Some people like to add chopped cilantro on top, which adds a fresh herbal note that cuts through the richness.
Fresh corn beats frozen or canned every single time
Corn tastes sweetest within hours of being picked, which means buying it from farmers markets or farm stands gives the best results. Grocery store corn works fine too, just look for ears with bright green husks and moist silk at the top. Peeling back a small section to check the kernels helps avoid dried-out or damaged ears. The kernels should look plump and milky when pierced, not shriveled or dented.
Frozen or canned corn turns mushy on the grill and lacks the natural sugars that caramelize into that signature char. Summer and early fall offer peak corn season in most places, when ears are cheap and abundant. Buying corn in season means better taste and lower prices. Store unshucked corn in the refrigerator if not using it immediately, since the sugars start converting to starch as soon as the corn gets picked. Using it within a day or two guarantees the sweetest possible results.
Melted butter can replace or complement the mayo
Some versions of this dish skip the mayo entirely and use butter mixed with lime juice and spices instead. The butter creates a lighter coating that lets the corn taste shine through more. Melting about a quarter cup of butter and stirring in lime juice, chili powder, and cayenne pepper makes a simple alternative. Brush this on the hot corn first, then add the cheese and extra seasonings on top.
Using both butter and mayo might sound excessive, but it actually works really well. Brush the corn with butter immediately after it comes off the grill, then add the mayo mixture over that. The butter soaks into the kernels while the mayo creates a creamy coating on the surface. This double-layer approach means every bite has richness from the butter and tanginess from the mayo. Either way works great, so pick based on personal preference or what’s already in the fridge.
Timing the corn for parties takes some planning
Making this corn for a crowd means thinking ahead about the boiling and grilling steps. The corn can be boiled a few hours early and kept at room temperature until grill time. This actually works better than trying to boil and grill everything at the last minute while guests are waiting. The spicy mayo mixture keeps in the fridge for up to three days, so making it the night before saves time during the actual party.
Grilling takes the longest since most home grills only fit four to six ears at once. Starting the grill early and working in batches keeps fresh corn coming out steadily. Keep finished ears warm by wrapping them loosely in foil, though they taste best eaten right off the grill. Setting up a self-serve station with the mayo, cheese, and extra toppings lets people customize their own corn, which takes pressure off the cook and gives guests something fun to do.
Leftover corn creates surprisingly good other dishes
Extra grilled corn rarely happens, but when it does, cutting the kernels off the cob opens up new possibilities. Those charred kernels add great taste to scrambled eggs, quesadillas, or pasta salads. Mix them with black beans, diced tomatoes, and avocado for a quick side dish that beats anything from a can. The smoky taste holds up even after being refrigerated overnight.
Corn cut off the cob and mixed with the leftover spicy mayo makes a version of esquites, the Mexican street corn salad served in cups. Add some diced jalapeños and a squeeze of lime for a dish that works as a dip with tortilla chips. The cheese and mayo mixture sticks to the kernels even after they’re cut off, so each bite still has that signature combination. Reheating the kernels in a skillet brings back some of the original smokiness and warms everything through without turning the corn mushy.
This spicy grilled corn beats plain butter-and-salt corn at every summer gathering. The combination of smoky char, creamy tangy sauce, and salty cheese creates something that tastes way more impressive than the simple technique requires. Making it once usually means getting requests for it at every cookout after that.
Spicy Grilled Corn With Lime and Cotija Cheese

kcalSmoky grilled corn slathered with spicy lime mayo and topped with crumbly cotija cheese beats plain buttered corn any day.
Ingredients
8 ears fresh corn on the cob, husked
½ cup mayonnaise
½ cup sour cream
1 lime, juiced, plus 1 teaspoon lime zest
1 tablespoon ground ancho chile powder
1 teaspoon smoked paprika
¼ cup butter, melted
1 cup freshly crumbled cotija cheese
Salt to taste
Lime wedges for serving
Fresh cilantro for garnish (optional)
Directions
- Preheat your outdoor grill to high heat and lightly oil the grates to prevent sticking. If using a charcoal grill, pile the coals high for intense direct heat. Set up your workspace with all the toppings ready to go before the corn comes off the grill.
- Bring a large pot of salted water to a rolling boil. Add the husked corn and boil for exactly 5 minutes to precook the kernels. Drain the corn thoroughly and pat each ear dry with paper towels to remove excess moisture, which helps achieve better charring on the grill.
- While the corn boils, make the spicy lime mayo by whisking together mayonnaise, sour cream, lime juice, lime zest, ancho chile powder, and smoked paprika in a medium bowl until completely smooth. Refrigerate the mixture until the corn is ready, allowing the spices to blend together.
- Place the dried corn ears directly on the hot grill grates. Cook for 8-10 minutes total, turning every 1-2 minutes with tongs to ensure even charring on all sides. Look for dark golden brown spots with slight blackening where the sugars have caramelized.
- Remove the corn from the grill and immediately brush each ear generously with melted butter while still hot. The heat will help the butter soak into the kernels and create a rich base layer for the other toppings.
- Use a pastry brush or silicone brush to coat each buttered ear with the spicy lime mayo mixture, working it into the crevices between kernels. Apply a generous coating but avoid using so much that it drips off excessively.
- Sprinkle the crumbled cotija cheese liberally over each ear while the mayo is still warm, pressing gently to help it stick. The residual heat will slightly soften the cheese without fully melting it.
- Finish each ear with a light dusting of extra ancho chile powder and a sprinkle of salt to taste. Serve immediately with lime wedges on the side for squeezing over the top, and garnish with fresh cilantro if desired.
Notes
- The spicy lime mayo can be made up to 3 days ahead and stored covered in the refrigerator, which actually improves the taste as the spices bloom.
- Parmesan cheese can substitute for cotija in a pinch, though it has a sharper, nuttier taste that changes the profile slightly. Feta works too but adds extra tanginess.
- For a lighter version, skip the sour cream and use all mayonnaise, or replace the mayo mixture entirely with melted butter mixed with lime juice and spices.
- Corn can be boiled several hours ahead and kept at room temperature until grilling time, making party prep much easier.
- Leftover kernels cut off the cob make excellent additions to scrambled eggs, quesadillas, pasta salads, or mixed with black beans for a quick side dish.
Frequently asked questions about spicy grilled corn
Q: Can I make this corn without boiling it first?
A: Yes, but it takes much longer on the grill and risks burning the outside before the inside cooks through. Boiling for 5 minutes ensures tender kernels while the grill focuses on creating those charred spots. Raw corn needs 15-20 minutes of grilling with the lid closed, and the results aren’t as good.
Q: What can I use if I can’t find cotija cheese?
A: Parmesan cheese works as the closest substitute with its salty, hard texture, though it tastes sharper and nuttier. Feta cheese also works but adds tanginess that changes the overall taste. In a real pinch, any hard grating cheese like pecorino romano will do, but cotija really makes the dish authentic.
Q: How do I keep the toppings from falling off the corn?
A: Brushing the mayo mixture on while the corn is still hot from the grill helps it stick better. Press the cheese gently into the mayo coating instead of just sprinkling it loosely. Working over a plate or tray catches any cheese that falls off so you can reapply it.
Q: Can I make this corn in the oven if I don’t have a grill?
A: Boil the corn as directed, then place it on a foil-lined baking sheet under the broiler for 5-8 minutes, turning every 2 minutes until charred. The results won’t have the same smoky taste as grilling, but the charred spots still add great caramelized sweetness. Keep the oven door slightly open and watch carefully since broilers vary in intensity.
