This Corn Tomato Avocado Salad brings vibrant colors and juicy flavors together in one bowl. Sweet corn kernels mix with peppery red onion, creamy avocado, and bright tomatoes all tossed in a tangy lime dressing. It is one of my favorite summer salads for picnics or quick lunches because it tastes just as fresh as it looks.

The first time I made this salad it was a sweltering July afternoon and I had garden tomatoes piling up on the kitchen counter. My family devoured every bite and now it is requested whenever we fire up the grill.

Ingredients

  • Corn kernels Quick sweetness and crunch Fresh off the cob is best but good frozen or well drained canned corn works
  • Avocado Ripe but firm Avocado gives creaminess and richness Look for ones that yield slightly to gentle pressure but are not overly soft
  • Tomatoes Choose ripe juicy tomatoes for best flavor Grape or cherry tomatoes also work and hold their texture well
  • Red onion Finely diced for a crisp bite Look for shiny taut skins and avoid any dried out pieces
  • Olive oil A good quality extra virgin oil will give a fruity depth
  • Lime juice Fresh squeezed for bright tartness Roll the lime on the counter first to release more juice
  • Salt Essential to bring out the flavors Use flaky sea salt if you have it
  • Black pepper Adds just enough heat Use freshly cracked for more flavor
  • Fresh cilantro Chop just the leaves for the best color and aroma Always choose bunches that smell fresh and are free of yellow spots

I have always loved the burst of sweetness from fresh corn in this recipe There is something extra satisfying about slicing it straight from the cob when local corn is in season A big bowl of this salad always makes me think of lazy summer cookouts and backyard laughter

Storage Tips

This salad is at its best eaten fresh but you can store leftovers in an airtight container in the refrigerator for up to one day The avocado may darken a bit but the lime keeps it fairly green To keep it looking its best press a piece of plastic wrap directly on the surface before sealing

Ingredient Substitutions

If you do not have fresh corn try thawed frozen or even well rinsed canned corn instead For more kick swap red onion for mild shallots or try green onion Add diced jalapeno or a pinch of chili flakes if you like heat Swap cilantro with fresh basil for a different twist

Pair this salad with grilled chicken shrimp or fish for a simple meal I like to pile it on crunchy tortilla chips for a party appetizer or spoon it over lettuce for a hearty summer lunch It is perfect alongside tacos or anything smoky from the grill
