Miso-Glazed Eggplant (Nasu Dengaku)

Method

1. Score the eggplant flesh in a deep crosshatch pattern, cutting about 1/2 inch deep without piercing the skin. Brush the cut surfaces with oil. The crosshatch creates surface area for browning and channels for the glaze to seep into.

2. Roast cut-side down at 400°F for 20 minutes until the flesh is soft and the surface is golden where it contacts the pan. Starting cut-side down softens the dense eggplant flesh before the glaze goes on.

3. Mix the miso glaze while the eggplant roasts: white miso, mirin, sugar, sake, and sesame oil. Stir until smooth. The combination of fermented miso (umami), mirin (sweet), and sesame (nutty) creates a glaze with extraordinary depth.

4. Flip the eggplant cut-side up. Spread the miso glaze generously over the scored flesh, pressing it into the crosshatch channels.

5. Broil for 3–5 minutes until the glaze is bubbling and caramelized with dark spots. Watch constantly — the sugars in the glaze burn fast under a broiler. The glaze should be glossy, bubbly, and deeply golden.

6. Top with sesame seeds and scallions. Serve immediately. The contrast of the sweet-savory caramelized glaze against the silky, creamy eggplant flesh is one of the great textures in Japanese cooking.

Equipment

• Rimmed sheet pan Recommended: Nordic Ware Natural Aluminum Half Sheet Pan
• Small bowl for glaze
• Pastry brush Recommended: OXO Good Grips Silicone Pastry Brush

Chef Notes

• The most important thing: Score the eggplant flesh in a deep crosshatch pattern before roasting. This serves two purposes: it helps the flesh cook evenly (eggplant is dense and insulating), and it creates channels for the miso glaze to penetrate into the flesh rather than sitting on the surface.
• Roast cut-side down first to soften the flesh, then flip and apply the glaze. Trying to glaze raw eggplant means the glaze burns before the eggplant is tender.
• White miso (shiro miso) is milder and sweeter than red miso. It caramelizes beautifully under the broiler without becoming bitter.
• Watch the broiler closely — the glaze goes from perfectly caramelized to burnt in about 30 seconds. The sugars in the miso and mirin brown rapidly.
• This is nasu dengaku — a classic Japanese preparation that showcases miso as a glaze rather than a soup ingredient.

Common Substitutions

Ingredient	Substitution	Notes
Pork belly	Thick-cut bacon (uncured)	Less fat but similar flavor. Reduce cook time.
Salmon	Trout, arctic char, or steelhead	All are fatty fish with similar cook times.
White wine	Chicken broth + 1 tsp lemon juice	Loses the wine fruit but keeps the acidity.
Sesame oil	Toasted walnut oil or peanut oil	Walnut oil is nuttier. Peanut oil for frying.
Sugar	Coconut sugar or maple syrup	Coconut sugar is 1:1. Maple: reduce liquid slightly.
Scallions	Chives or thinly sliced leek greens	Chives are milder. Leek greens are closest in flavor.

What You're Practicing

Using miso as a glaze teaches you about fermented ingredients as flavor enhancers. Miso is packed with glutamic acid (umami), and when caramelized, it develops complex sweet-savory flavors that no single ingredient can replicate. This same glazing technique works on salmon, pork belly, and roasted squash. Visit Spice Blends for more on Japanese seasonings.

The two-stage cooking method (roast then broil) gives you control over both the interior texture and the surface finish. Roasting softens the eggplant; broiling caramelizes the glaze. This same approach is used for crème brûlée (bake then torch), BBQ ribs (bake then broil), and gratins. Visit Techniques for more on two-stage cooking.
