This recipe is based on the classic Japanese side dish, nasu dengaku. And while it is popular in the summer, this is my favorite way to prepare eggplant in the winter. It is so warm and cozy. Just pair it with a simple green salad and toasted garlic green beans for a quick and easy vegetarian dinner.

📖Why My Recipe Works

There are three things that make this the best miso-glazed eggplant recipe.

First, the cross-hatch method, similar to my take on Thomas Keller zucchini, ensures the inside of the eggplant becomes creamy but doesn't overcook the outside.
Second, I replaced the traditional sugar or honey with brown sugar. Brown sugar has a richer flavor but tastes overall less sweet. Plus it is vegan so no need to substitute maple syrup.
Finally, I skipped the soy sauce and used kosher salt. I thought the soy sauce overwhelmed the umami flavor of the miso. Plus I can control the salt level better. Plus it means this recipe is naturally gluten-free as well. I think these minor changes balance out the savory miso sauce.

🧾Ingredient Notes

White Miso Paste - Miso paste is made from fermented soybeans and rice. The most familiar application for many people is in miso soup.

There are several types of miso paste available, the most common being red and white.

Red miso is fermented for a longer period and contains a higher ratio of soybeans compared to white miso. Red miso paste also has a stronger flavor.

To ensure that the glaze doesn't cover up the delicate flavor of the eggplant, I recommend using the white variety. It's easily found in mainstream grocery stores as well as Asian markets.

Eggplant - Any eggplant is fine here, so feel free to experiment with different varieties. I love going to farmers' markets in the summer and buying whatever I think looks fun. You can use Japanese eggplants, fairytale eggplant, or Italian eggplant. Just adjust the cooking time based on the size of the eggplant you choose.
Brown Sugar - Light or dark brown sugar will work here. I prefer light, but if you only have dark brown sugar in your pantry, don't let that stop you from making this recipe.
Rice Vinegar - Rice vinegar, also called rice wine vinegar, is less acidic than many other kinds of vinegar, and its flavor pairs nicely with the miso.
Toasted Sesame Oil - The nutty flavor of toasted sesame oil really adds a depth of flavor to this recipe and, of course, plays really well with the other Asian-inspired flavors of this recipe.
If you don't have sesame oil you can substitute olive oil or vegetable oil, but I really don't think it tastes as divine. You will need a high heat oil (i.e. not olive oil for searing the eggplant).
Red Pepper Flakes- For additional spice, you can increase the amount of red pepper flakes, or add a tablespoon of gochujang, a Korean fermented pepper paste that is funky, spicy, and sweet.
Green Onions and Sesame Seeds - Optional for garnishing

⏲️How to Make Miso Eggplant

You'll love how simple and quick this miso eggplant recipe is. The flavors of the miso and eggplant are so wonderful together. Before starting preheat your broiler and line a rimmed baking tray with foil. You can use parchment paper but I find foil makes for easier cleanup.

Prep the Eggplant

Start by cutting the eggplant in half lengthwise. Use a sharp paring knife to score the eggplant flesh in a criss-cross pattern. Going diagonally in one direction and then again in a perpendicular pattern.

Aim for at least ¼ to ½ an inch deep - go as deep as you can without slicing the skin. Sprinkle the eggplant with salt.

Cook the Eggplant

Heat the cooking oil over medium heat in a large saute pan. Put the cut side of the eggplant up and the peel side down. Sear for three minutes. Flip over the eggplant halves and cover the pan with a lid. Reduce the heat a bit, then steam the eggplant for four minutes.

Make the Miso Glaze

While the eggplant steams, mix together the miso paste, sesame oil, pepper flakes, rice vinegar, and brown sugar in a small bowl. You can taste the sauce and adjust the salt as needed.

Try this glaze on other vegetables like roasted carrots, zucchini, or summer squash, or even on grilled chicken. You can even use it on my simple roasted eggplant slices.

Broil

Transfer the eggplants to your baking sheet. Flip them flesh side up and brush the glaze over the tops - don't be shy about it. This recipe really benefits from slathering the eggplant with the glaze.

Place the miso glazed eggplant under the broiler for 4 to 5 minutes until golden and bubbly. Garnish with sesame seeds and sliced green onions, and serve immediately.

Air Fryer Option

Personally, I think it is best to cook the eggplant on the stove and then broil. The sweet miso glaze will completely carmelize. But sometimes it is easier to whip out the air fryer.

Preheat the air fryer to 375 F. Cut the eggplant in the same way, brush both sides with oil before cooking for 5 minutes flesh side down. Flip and cook another 5 to 6 minutes until the eggplant is soft. Brush on the glaze and cook another two minutes.

🥗What to Serve with Miso Glazed Eggplant

This miso eggplant would be great served alongside any of your favorite proteins, but I definitely recommend giving this salt and pepper shrimp a try. Because of the softer texture, I recommend pairing with firmer side dishes like sushi rice, green beans, asparagus, or carrots.

Expert Tips

Keep a close eye on the eggplant as it broils. The brown sugar in the glaze can go from perfectly caramelized to burnt faster than you might imagine!
This miso glaze is absolutely perfect for use on other vegetables. Some ideas could be yellow squash, broccoli, carrots, or even corn on the cob!

🌡️Storing Leftovers

The glaze can be made in advance and kept in a sealed container in the refrigerator for up to a week. Keep any leftover glaze to use on fish or chicken. While best eaten immediately.

Leftover eggplant can be stored in a sealed container in the refrigerator for up to 3 days. Reheat in a pan or a 350°F oven.
