Air Fryer Japanese Eggplant Recipe

This Air Fryer Japanese Eggplant Recipe Is So Easy & Delicious

I still remember the first time I tried nasu dengaku—a Japanese miso-glazed eggplant dish. It was at a cozy izakaya-style restaurant during a girls’ trip to San Francisco. I wasn’t expecting to fall head-over-heels for something as humble as eggplant, but wow—each bite was sweet, savory, silky, and perfectly caramelized. Since then, I’ve been hooked.

The good news? You don’t need a flight to Tokyo—or even a reservation—to enjoy this dish. With a few pantry ingredients and an air fryer, you can make your own Japanese eggplant recipe that’s easy, healthy, vegan, and absolutely delicious.

Let’s dive into one of my favorite ways to cook aubergine that works for busy weeknights, meal prep, or impressing your foodie friends.

This Air Fryer Japanese Eggplant Recipe Is So Easy & Delicious

What Is Japanese Eggplant?

If you’ve only used the standard globe eggplant, it’s time to meet its more delicate cousin: Japanese eggplant. These slender, deep purple beauties are known for their tender flesh, thin skin, and subtly sweet flavor.

They cook quickly, absorb marinades like a dream, and are ideal for dishes like stir-fries, curries, or our star recipe today: air fryer nasu dengaku.

Also known as aubergine in some parts of the world, Japanese eggplant is a great option when you’re looking to add more veggies to your meals without sacrificing flavor or satisfaction.

Why the Air Fryer Is a Game-Changer for Eggplant

Before I had an air fryer, I used to roast eggplant in the oven. While tasty, it took longer and required more oil for that caramelized finish. The air fryer, though? It creates crispy edges and silky centers with just a light brush of oil—and in half the time.

This method:

  • Keeps the dish healthy
  • Makes cleanup easy
  • Delivers restaurant-quality results in minutes
  • It’s one of the best ways to cook eggplant, especially if you're trying to simplify your weeknight routine without sacrificing taste.

    What Is Nasu Dengaku?

    Let’s talk about the miso glaze that makes this dish shine.

    Nasu dengaku is a traditional Japanese side dish made by broiling or grilling eggplant and slathering it in a rich, umami-packed miso glaze. The name loosely translates to “temple-style eggplant,” and it’s a common dish in Japanese home cooking.

    The glaze combines white miso, a touch of sweetness (like maple syrup), a splash of rice vinegar, and mirin—creating that perfect balance of salty, sweet, and tangy. And yes, it’s totally vegan.

    Ingredients (Exact Measurements)

    Here’s everything you’ll need to make this recipe. It serves 2 as a main, or 4 as a side.

    For the Eggplant:

  • 2 medium Japanese eggplants, halved lengthwise
  • 1 tablespoon sesame oil (or avocado oil)
  • For the Alcohol-Free Miso Glaze:

  • 2 tablespoons white miso paste
  • 2 tablespoons rice vinegar
  • 2 teaspoons maple syrup (extra for mirin sub)
  • 1 teaspoon soy sauce (or tamari for gluten-free)
  • 1 teaspoon toasted sesame oil
  • Optional Garnishes:

  • 1 teaspoon toasted sesame seeds
  • 2 green onions, thinly sliced
  • A pinch of chili flakes (if you like heat)
  • Step-by-Step Instructions

    Step 1: Prep the Eggplant

    Slice the eggplants in half lengthwise. Score the flesh in a criss-cross pattern without cutting through the skin—this helps the glaze absorb and speeds up cooking.

    Brush the cut sides with sesame oil.

    Step 2: Air Fry

    Preheat your air fryer to 375°F (190°C). Place the eggplant halves cut side up in the basket (you may need to work in batches).

    Air fry for 12–15 minutes, or until the flesh is soft and the edges are golden brown.

    Step 3: Make the Alcohol-Free Miso Glaze

    While the eggplant is cooking, whisk together the miso paste, rice vinegar, maple syrup (both tablespoons and teaspoons), soy sauce, and toasted sesame oil in a small bowl. The mixture should be thick but spreadable.

    Step 4: Glaze and Finish

    Remove the eggplant from the air fryer. Brush the tops generously with the miso glaze.

    Return to the air fryer for 2–3 more minutes to allow the glaze to caramelize.

    Can I Use the Oven Instead?

    Absolutely. If you don’t own an air fryer, simply place the oiled eggplant halves on a baking sheet and roast in a 400°F oven for 20–25 minutes, then broil for 2–3 minutes after adding the glaze.

    But for the crispiest results with less oil and faster cooking, the air fryer still wins for me!

    Why This Recipe Is So Good for You

    This dish checks all the boxes:

  • Vegan
  • Gluten-free (with tamari)
  • Low in calories
  • High in fiber
  • Full of antioxidants from eggplant skin
  • Fermented miso = good for gut health!
  • It’s a go-to for me when I want something comforting but not heavy—and it keeps really well for leftovers.
