This easy grilled corn and avocado salad has charred sweet corn, blistered shishito peppers, creamy avocado, and cherry tomatoes tossed in a tangy Greek yogurt ranch that skips the mayo. It comes together in 20 minutes, travels well, and is the side that disappears first at every BBQ I bring it to.
Make the Dressing: Make the ranch by mixing all the ingredients in a small bowl. Add a little water at a time until it reaches your desired consistency. Let it sit for 20–30 minutes so the flavors can meld.
Grill the Corn: Preheat your grill to medium-high heat, around 400°F. Grill the corn for about 5 minutes on each side until slightly charred and cooked through.
Grill the Peppers: Add the shishito peppers to the grill during the last 5 minutes. Let them blister and char on one side until they soften and turn a darker olive green.
Prep the Veggies: Once the corn and peppers have cooled enough to handle, cut the kernels off the cob and chop the shishito peppers.
Assemble the Salad: In a large bowl, combine the grilled corn, chopped shishitos, cherry tomatoes, soaked red onion, and cubed avocado.
Dress and Serve: Season with salt and pepper. Drizzle with the ranch and toss gently. Add more dressing or fresh herbs if you'd like.
Notes
Soak the red onion: Soak the diced red onion in cold water for 10 minutes to mellow its sharpness, then drain before adding.Make the ranch first: Prepare the Greek yogurt ranch first and let it rest while you grill so the dried herbs have time to bloom.Add shishitos late: Add the shishito peppers in the last 5 minutes of grilling so they blister without going soft.Dress before serving: Toss the salad with the dressing just before serving to keep the avocado fresh and the corn with a little texture.No grill? Char the kernels off the cob in a hot cast iron skillet for 8 to 10 minutes, and blister the shishitos in the same pan.Storage: Store leftovers airtight in the fridge for up to 2 days. Keep the dressing separate if making ahead. Do not freeze.
