This air fryer miso glazed eggplant is one of my favorite ways to cook eggplant. The flesh gets soft and creamy on the inside while the miso glaze caramelizes on top – it’s honestly so good.
If you’ve never tried eggplant with miso before, you’re in for a treat. The glaze is savory, slightly sweet, and packed with umami flavor that soaks right into the scored flesh.
The air fryer does a great job here. It cooks the eggplant evenly and gets that glaze nice and bubbly without heating up your whole kitchen.
You can serve this as a side dish with pretty much any protein, or just put it over a bowl of steamed rice for a simple meal. Either way, it comes together in about 20 minutes.
The ingredient list is short and simple – mostly pantry staples if you keep basic Asian ingredients on hand. Let me show you how to make it.
Why You’ll Love This Recipe
The Miso Glaze Caramelizes Perfectly in the Air Fryer – The combination of miso paste, honey, and mirin creates this incredible sticky glaze that bubbles and caramelizes in just 4-5 minutes under the air fryer’s heat. It gets that slightly charred, sweet-savory finish that you would normally only get from a restaurant broiler.
Eggplant Gets Silky Soft Without Deep Frying – Eggplant is famous for soaking up oil like a sponge, but air frying it means you only need a light brush of vegetable oil. The flesh still turns perfectly creamy and tender without all that extra grease.
The Crosshatch Scoring Trick Is a Game Changer – Scoring the eggplant in a diamond pattern is not just for looks. It lets the miso glaze seep deep into the flesh so every single bite is packed with that umami-rich flavor instead of just sitting on top.
It Only Takes About 20 Minutes Total – From the moment you turn on your air fryer to the moment you are eating, this whole recipe takes roughly 20 minutes. That is seriously fast for a dish that looks and tastes like it took way more effort.
Ingredients
- 2 Large Eggplants
- 3 tbsp White Miso Paste
- 1 tbsp Mirin
- 1 tbsp Rice Vinegar
- 1 tbsp Honey
- 1 tsp Sesame Oil
- 1 tbsp Soy Sauce
- 1 tbsp Vegetable Oil
- 1 tsp Sesame Seeds
- 2 Green Onions (thinly sliced)
- 1/2 tsp Red Pepper Flakes (optional)
How to Make
Step 1
Cut the eggplants in half lengthwise. Score the flesh in a crosshatch diamond pattern about 1/2-inch deep, being careful not to cut through the skin.
Step 2
Brush the scored flesh of each eggplant half with vegetable oil. Preheat the air fryer to 375F and place the eggplant halves cut-side up. Air fry for 12-14 minutes until the flesh is softened and lightly golden.
Step 3
While the eggplant cooks, whisk together the miso paste, mirin, rice vinegar, honey, sesame oil, and soy sauce until smooth.
Step 4
Remove the eggplant from the air fryer and spoon the miso glaze generously over the scored flesh, letting it seep into the cuts. Return to the air fryer and cook for an additional 4-5 minutes until the glaze is bubbling and caramelized.
Step 5
Top with sesame seeds, sliced green onions, and red pepper flakes if desired. Serve immediately as a side dish or over steamed rice.
Tips
Pick the Right Eggplants
You want eggplants that feel heavy for their size and have smooth, shiny skin without any wrinkles or soft spots. Wrinkled skin usually means the eggplant is old, and older eggplants tend to be more bitter and have tougher seeds inside.
Try to pick eggplants that are roughly the same size so they cook evenly in the air fryer. If one is much bigger than the other, the smaller one will be done way before the larger one and you will end up with uneven results.
Make the Glaze While the Eggplant Cooks
You have 12-14 minutes while the eggplant air fries, so use that time to whisk the glaze together. Miso paste can be clumpy, so add the liquid ingredients first and then work the miso into them bit by bit until the mixture is completely smooth with no lumps.
If your miso paste is really thick and hard to mix, warm it up for about 10 seconds in the microwave before combining it with the other ingredients. That softens it enough to blend in easily.
Having the glaze ready to go the second the eggplant comes out is important. You do not want the eggplant sitting around cooling down while you are still mixing things together.
Brush the Oil Evenly
Make sure you get vegetable oil into the scored cuts, not just across the surface. A silicone pastry brush works best here because it can push the oil down into those diamond-shaped grooves you made.
The oil helps the flesh soften up during that first round of cooking and gives you a light golden color before the glaze goes on. If you skip the oil or just barely use it, the eggplant can dry out and get tough in the air fryer instead of turning creamy and tender.

Frequently Asked Questions
Why do I need to score the eggplant before air frying?
Scoring the flesh in a crosshatch pattern helps the eggplant cook faster and more evenly in the air fryer. Those little diamond cuts also create pockets for the miso glaze to seep into, so every bite is packed with flavor instead of just sitting on the surface.
Try to cut about 1/2-inch deep without going through the skin. The skin acts like a little bowl that holds everything together, so you want to keep it intact.
