Grilled until crisp at the edges and finished with a bright miso-ginger drizzle, this miso grilled eggplant makes the most of peak-season eggplant and pairs beautifully with any Asian-inspired meal.
I picked up the first eggplants of the season at the farmer’s market a few weeks ago and immediately began developing this recipe. The grill felt like the obvious choice: it’s still sweltering outside and firing up the oven felt like a mistake.
A simple miso-ginger marinade adds savory, slightly sweet, umami-rich flavor that soaks into the eggplant while the grill crisps the edges and adds light char. The result is a summer side dish that feels both special and effortless.
Even if eggplant hasn’t won you over before, I encourage you to give this preparation a try. The grill transforms the typically mild vegetable into tender, flavorful slices with golden, crisped edges — irresistible as a side, snack, or component of a larger meal.

Making the Grilled Eggplant
(Full recipe and detailed instructions follow below.)
Ingredients You Will Need
- Eggplant (full-size or mini)
- Vegetable oil
- Soy sauce (low-sodium recommended)
- White miso paste
- Rice wine vinegar
- Honey or agave nectar
- Sriracha (optional, to taste)
- Garlic, grated
- Fresh ginger, grated
- Salt and pepper
- Sliced green onions for garnish
Choosing Your Eggplant
This recipe is flexible and works well with both larger globe eggplants and long Japanese or Chinese varieties. Slice any eggplant into even 1/4-inch-thick pieces so they cook uniformly. For very large rounds, you can halve the circles if you prefer smaller portions.
If you’re using smaller eggplants with thin slices, consider a grill pan on the stovetop to prevent pieces from slipping through the grates. Either method gives excellent caramelization when cooked over high heat.
Tips for Perfect Grilled Eggplant
- Oil, salt, and pepper the slices: A light coating of oil plus a pinch of kosher salt and freshly ground black pepper prevents sticking and seasons the eggplant.
- Use fresh aromatics: Grated garlic and fresh ginger give the miso sauce a bright, authentic flavor you can’t get from powders.
- Marinate briefly: Ten to twenty minutes is enough for the miso mixture to flavor the slices without making them mushy. Turn the slices halfway through to coat both sides.
- Grill hot and fast: Preheat the grill to about 400°F (or heat a cast-iron grill pan over medium-high). Cook just a few minutes per side to char and caramelize the exterior while keeping the interior tender.
- Reserve the marinade: Save the leftover marinade and drizzle it (warmed if you prefer) over the grilled slices for an extra boost of flavor.
Recipe Variations
Small changes let you customize the dish to your taste or make it part of a larger plate.
- Increase the heat: Add more sriracha or a sprinkle of crushed red pepper flakes for spicier eggplant.
- Grill additional vegetables: Bell peppers, zucchini, mushrooms, and scallions all grill well alongside eggplant and make a colorful platter.
- Add protein: Serve with grilled tofu, chicken, pork, or steak for a complete meal; drizzle the same miso sauce over the protein.
- Finish with sesame: A light sprinkle of toasted sesame seeds and a splash of toasted sesame oil lifts the flavor.
Stovetop Instructions
If you don’t have an outdoor grill, use a well-seasoned cast-iron pan or a cast-iron grill pan on the stovetop. Lightly oil the pan and cook eggplant in a single layer, working in batches, over medium-high heat until golden brown and tender, about 2–3 minutes per side depending on thickness.
The miso gives the dish a deep savory backbone while the ginger, vinegar, and honey create balance. The edges crisp beautifully while the interior stays tender, making these slices perfect to pick up and eat right off the plate.
Make a batch when eggplant is abundant and enjoy it as a repeating summer favorite. It’s easy to scale up for a crowd and versatile enough to feature across weeknight dinners and weekend cookouts.

Miso Grilled Eggplant
Ingredients
- 1–1/2 lbs eggplant (full-size or mini)
- Kosher salt and pepper, to taste
- 2 tablespoons vegetable oil
- 2 tablespoons low-sodium soy sauce
- 2 tablespoons white miso paste
- 2 tablespoons rice wine vinegar
- 2 tablespoons honey or agave nectar
- 1 tablespoon sriracha (optional)
- 1 medium clove garlic, grated
- 2 teaspoons grated fresh ginger
- Sliced green onions, for serving
Instructions
- Trim the eggplant ends and slice into 1/4-inch-thick rounds. Arrange the slices in a shallow dish, season lightly with salt and pepper, then toss with the vegetable oil to coat. Set aside.
- In a small bowl, whisk together the soy sauce, miso, rice vinegar, honey, sriracha (if using), grated garlic, and grated ginger until smooth.
- Pour the soy-miso mixture over the eggplant and toss to coat. Let the slices sit for 10 minutes, flip them, and let sit another 10 minutes to absorb flavor.
- Preheat an outdoor grill to about 400°F and oil the grates. Alternatively, heat a lightly oiled cast-iron grill pan over medium-high heat.
- Remove the eggplant from the marinade (reserve the remaining marinade). Place slices in a single layer on the preheated grill or pan and cook 2–3 minutes per side, until tender and lightly charred. Work in batches if needed.
- Transfer grilled eggplant to a serving plate, drizzle reserved marinade over the top, and garnish with sliced green onions. Serve immediately.
Notes
Storing Instructions: Eggplant is best served right after grilling. If you need to store leftovers, keep them refrigerated in an airtight container and reheat gently in a skillet to restore some of the crisp edges.
