Grilled eggplant can be one of the great treats of summer—lusciously tender eggplant, with bits of crispy charred edges here and there. It works on its own, as part of a grilled vegetable platter, or even as a stand-in for a meat patty in burgers. Sadly, it is more commonly either overcooked and flavorless or undercooked and spongy. Luckily, there is a way to grill tender, flavorful eggplant.

This easy recipe uses the power of salted water (or brining) to guarantee great grilled eggplant. It's easy and adds 30 minutes to this otherwise quick recipe, but it's worth it. Every time you pop a few slices of this brilliantly flexible vegetable on a hot grill, it will come off crispy brown on the outside, creamy sweet on the inside, and full of flavor.

Feel free to embellish with spices and other flavors. Serve it with a drizzle of balsamic vinegar, a dollop of pesto, a spoonful of romesco, or a scattering of crumbled feta cheese and make this simple technique a recipe of your own. Grilled eggplant is also particularly yummy with a few grilled tomatoes at its side.

  7. Meanwhile, heat a charcoal or gas grill to medium-high heat. You should be able to hold your hand about an inch above the cooking grate for 3 to 4 seconds before pulling it away from the heat.

  8. Drain the eggplant and pat it dry with paper towels or a clean kitchen towel.

  11. Brush the top sides of the slices with oil and sprinkle them with salt. Turn the slices over, close the lid of the grill, and cook until grill marks appear on the other side and the eggplant is very tender; about 5 more minutes.

  • Depending on the size of your grill, you may need to cook the eggplant in two batches.
  • Be sure to use a heat-resistant basting brush when grilling.

Why Is Brining Eggplant so Important?

Raw eggplant has a slightly bitter taste, and it's full of moisture. Brining helps lock in that moisture through osmosis, so the fruit's flesh holds together on the grill. It also transforms the raw taste into a delicious sweetness, and the salt enhances the eggplant's flavor.

Should Eggplant Be Peeled Before Grilling?

Some people find eggplant skin difficult to digest. However, leaving the skin on for grilling helps the eggplant slices keep their shape on the grill and makes them easier to handle. Diners don't need to eat the skin.

Recipe Variations

  • For more flavor, sprinkle dried or fresh oregano and parsley on the eggplant along with the salt or use an Italian seasoning mix. You can also stir minced garlic into the olive oil.
  • Some grilled eggplant fans enjoy brushing Italian dressing onto the slices. It's an oil-heavy dressing, so no extra oil is required.
