This salad is grilled corn kernels, diced avocado, cherry tomatoes, jalapeรฑo, and red onion tossed in a cumin-spiked lime vinaigrette, finished with Cotija and cilantro. It comes together in about 32 minutes and holds its own as a side or a light main. The honest reason to make it: the char on the corn does most of the flavor work, so the rest of the ingredients barely need help.
What makes this version work
Two things matter here. First, getting a real char on the corn โ not just grill marks, but actual dark spots on multiple sides. That takes 10 to 12 minutes over medium-high heat with the lid open, turning every 2 to 3 minutes. Rushing it or using low heat gives you steamed corn in a salad, which is flat. Second, the dressing is built to cling. Whisking the olive oil into the lime juice with Dijon mustard creates a loose emulsion that coats the kernels and avocado instead of pooling at the bottom of the bowl. Dress it at the table โ a pre-dressed salad goes limp fast, especially once the avocado is cut.
Leftovers and meal prep
The corn, dressing, tomatoes, onion, and jalapeรฑo can all be prepped up to 24 hours ahead and stored separately in the fridge. Keep the dressing in a sealed jar and give it a shake before using โ it will separate overnight. Cut the avocado only when youโre ready to serve; it browns within a couple of hours even with lime juice present. If you do end up with a fully assembled leftover portion, press a piece of plastic wrap directly against the surface to slow oxidation and eat it within 4 hours. The corn and tomato base (without avocado) keeps well for up to 2 days refrigerated and works well spooned over rice or into a wrap.
Troubleshooting
- Dressing tastes flat or too sharp: Lime juice strength varies a lot by fruit. If the dressing is too tart, add a little more honey or agave, half a teaspoon at a time. If it tastes dull, it likely needs more salt โ season the dressing itself, not just the finished salad.
- Corn is releasing too much liquid into the bowl: Let the cut kernels cool fully on the cutting board before adding them to the other ingredients. Hot corn releases steam and water that dilutes the dressing and softens the tomatoes quickly.
- Avocado is turning mushy: Use firm-ripe avocados โ they should yield to gentle pressure but not feel soft. Cut them last and fold them in gently; over-mixing breaks them down into a paste that muddies the whole salad.
- Salad tastes one-dimensional: This usually means the corn didnโt get enough char. If youโre using a grill pan indoors, make sure itโs fully preheated and donโt crowd the corn โ cook one or two ears at a time if needed so the pan stays hot.
- Cotija isnโt available: Crumbled feta is the closest substitute in terms of saltiness and texture. Reduce any additional salt in the dressing slightly, since feta tends to run saltier than Cotija.
Grilled Corn and Avocado Salad with Lime
Equipment
- Grill (gas or charcoal) or grill pan
- Tongs
- Chef's Knife
- Cutting board
- Large mixing bowl
- Small bowl or measuring jug
- Whisk
- Microplane zester
- Measuring cups and spoons
Ingredients
For the Grilled Corn:
- 4 ears fresh corn on the cob husked and silk removed
- 1 tbsp neutral oil for brushing (avocado or canola oil)
- ยผ tsp kosher salt
For the LimeโChili Vinaigrette:
- ยผ cup fresh lime juice from 2โ3 limes
- 1 tsp lime zest finely grated
- โ cup extra-virgin olive oil
- 1 tbsp honey or agave nectar
- 1 tsp Dijon mustard
- 1 clove garlic finely grated
- ยฝ tsp ground cumin
- ยฝ tsp chili powder preferably ancho
- ยฝ tsp kosher salt to taste
- ยผ tsp freshly ground black pepper
To Assemble:
- 1 ยฝ cups cherry tomatoes halved
- โ cup red onion finely diced
- 1 piece jalapeรฑo seeded and finely minced
- ยผ cup fresh cilantro leaves roughly chopped, plus more for garnish
- 2 medium ripe avocados diced 3/4-inch (firm-ripe for best texture)
- ยฝ cup Cotija cheese crumbled (optional)
- 4 wedges lime for serving
Instructions
- Preheat the Grill: Heat a clean, oiled grill to medium-high (about 450ยฐF / 232ยฐC). If using a grill pan, preheat over medium-high until lightly smoking.
- Season the Corn: Pat the husked corn dry. Brush evenly with neutral oil and sprinkle with 1/4 tsp kosher salt, rolling to coat all sides.
- Grill the Corn: Place corn on the hot grates. Grill, turning every 2โ3 minutes, until lightly charred and tender, 10โ12 minutes total. Transfer to a board and let cool 5 minutes, then slice kernels off the cobs by running a knife down the sides.
- Make the LimeโChili Vinaigrette: In a small bowl or measuring jug, whisk lime juice, lime zest, honey, Dijon, garlic, cumin, chili powder, salt, and pepper. While whisking, stream in olive oil until the dressing is glossy and emulsified, about 30โ45 seconds.
- Build the Salad Base: In a large mixing bowl, combine cherry tomatoes, red onion, jalapeรฑo, cilantro, and the warm grilled corn kernels. Drizzle with about half of the vinaigrette and toss to coat evenly.
- Fold in the Avocado: Add the diced avocados and gently fold with a spatula so the cubes stay intact. Add more vinaigrette to taste and adjust seasoning with a pinch of salt if needed.
- Finish and Serve: Sprinkle with crumbled Cotija. Plate the salad and garnish with extra cilantro and lime wedges. Serve slightly warm or at room temperature.
- Indoor Alternative: If not grilling outdoors, char the corn on a preheated grill pan over medium-high, 10โ12 minutes, or under a broiler set to High (about 500ยฐF / 260ยฐC), turning until charred, 8โ10 minutes.
Notes
Chefโs Tips:
- Choose firm-ripe avocados so they hold their shape; if very soft, dice larger and fold gently at the end.
- For deeper char, let the corn sit undisturbed for a full 2โ3 minutes per side before turningโpatience builds flavor.
- Make-Ahead: Grill and cut the corn up to 1 day in advance and refrigerate. Whisk the vinaigrette up to 5 days ahead; bring to room temp and re-whisk before using.
- Dairy-Free Option: Swap Cotija for 1/3 cup toasted pepitas for crunch and richness.
- Heat Control: Include some jalapeรฑo seeds for extra kick, or substitute with a milder serrano or a pinch of smoked paprika for less heat, more smokiness.
- Season to Balance: If the salad tastes flat, add a pinch of salt. If itโs sharp, add a drizzle more olive oil or a touch of honey. A final squeeze of lime right before serving brightens everything.

Common questions
Can I use frozen or canned corn instead of fresh ears?
Frozen corn works, but you need to dry it thoroughly and char it in a very hot cast-iron skillet rather than a grill. Spread it in a single layer, donโt stir for 2 to 3 minutes, and let it actually blacken in spots. Canned corn is too wet and soft to char properly and will make the salad watery.
How do I keep the avocado from browning if Iโm making this for a party?
Cut and dice the avocado as close to serving time as possible โ ideally within 30 minutes. Tossing the pieces in a small amount of the lime dressing right after cutting slows browning slightly, but it wonโt prevent it entirely beyond a couple of hours.
Is this salad served warm, cold, or at room temperature?
Room temperature or slightly warm is best. The corn can go into the bowl while still a bit warm from the grill, and the other ingredients are fridge-cold, so they balance out naturally. Serving it fully chilled mutes the flavor of the dressing.
How spicy is this with one jalapeรฑo?
With the seeds removed, one minced jalapeรฑo adds mild background heat spread across four servings โ most people wonโt find it hot. If you want more kick, leave some seeds in; if youโre cooking for kids or heat-sensitive guests, swap the jalapeรฑo for a small amount of finely diced green bell pepper.
Can I make this dairy-free?
Yes โ just skip the Cotija. The salad is fully dairy-free without it. For a bit of salty, savory contrast in place of the cheese, toasted pepitas or a light sprinkle of flaky sea salt at the end both work well.
