Roasted Eggplant Katsu with Creamy Curry Sauce

Crisp on the outside, almost buttery-soft inside, and served over a silky coconut curry sauce, this Roasted Eggplant Katsu is one of those vegetarian dishes that feels far more indulgent than the ingredient list suggests.

I love eggplant, but I think the way you cook it completely changes its personality. Roasted whole, the flesh becomes incredibly soft and almost smoky, without needing much oil. I decided to take that soft roasted eggplant, coat it in flour, egg, and panko, and fry it until beautifully golden and crisp.

And honestly, the contrast is probably my favourite part of this dish.

You cut through that crunchy panko crust and underneath is this incredibly tender eggplant that almost melts into the curry sauce.

For the sauce, I wanted something inspired by the comforting flavours of Japanese katsu curry, but with my own little twist. I cooked onions, carrots, and sweet potato with ginger, garlic, and warm spices, then added soy sauce, a touch of sugar, coconut milk, and stock. Once everything was completely tender, I blended it into a smooth golden curry.

The carrot and sweet potato naturally add sweetness and body, while coconut milk makes it creamy without feeling too heavy.

Served with steamed rice, sesame seeds, and spring onions, it makes such a satisfying meat-free meal — and visually, that golden crispy eggplant against the deep yellow curry is beautiful too.

Roasted Eggplant Katsu with Curry Sauce

Serves 3–4

For the Eggplant Katsu

• Eggplants 2 medium
• Salt and black pepper, to taste
• All-purpose flour, ½ cup
• Eggs, lightly beaten: 2
• Panko breadcrumbs, 1½ cups
• Neutral oil, for shallow frying

For the Curry Sauce

• Oil 1 tbsp
• Onion, roughly chopped, 1 medium
• Garlic cloves, 2, chopped
• Freshly grated ginger, 1 tbsp
• Carrot, 1, peeled and diced
• Sweet potato,  1, peeled and cubed
• Curry powder, 1½ tbsp
• Turmeric ½ tsp 
• Paprika ½ tsp 
• Soy sauce 1 tbsp
• Sugar, depending on taste, 1–2 tsp
• Vegetable stock, 1½ cups
• Coconut milk, ¾ cup
• Salt and pepper, to taste

To Serve

• Steamed rice
• Spring onions
• Sesame seeds
• Fresh coriander, optional
• Chilli oil, optional

Method

1. Preheat the oven to 220°C. Prick the eggplants a few times with a fork and place them whole on a lined baking tray. Roast for approximately 30–40 minutes, depending on their size, until completely tender and the skin has started to wrinkle and darken.
2. Remove from the oven and allow them to cool slightly. Carefully peel away the skins while trying to keep the eggplants intact. Place them on a plate lined with kitchen paper for a few minutes to absorb any excess moisture.
3. Gently flatten each eggplant slightly. Season with salt and pepper. Heat the oil in a saucepan over medium heat. Add the onion and cook until soft and translucent. Add the ginger and garlic and cook for another minute until fragrant.
4. Add the carrot and sweet potato, followed by the curry powder, turmeric, and paprika. Stir everything together and cook the spices for about a minute. Add the soy sauce and sugar. Pour in the vegetable stock and bring everything to a gentle simmer.
5. Cook for approximately 15–20 minutes, or until the carrot and sweet potato are completely tender. Add the coconut milk and simmer for another 3–4 minutes. Remove from the heat and allow the mixture to cool slightly.
6. Transfer to a blender and blend until completely smooth and velvety. Return the curry sauce to the saucepan. If it feels too thick, add a little more vegetable stock or water until you reach your preferred consistency. Taste and adjust the salt, soy sauce, or sugar if necessary.
7. Prepare three shallow bowls: one with flour, one with the beaten eggs, and one with the panko breadcrumbs. Very carefully coat each roasted eggplant first in flour.
8. Dip into the egg wash, then generously coat with panko breadcrumbs, pressing the crumbs gently onto the surface. Because the roasted eggplant is very tender, handle it carefully throughout this process.
9. Heat a shallow layer of neutral oil in a large frying pan over medium heat. Once hot, carefully add the breaded eggplant. Fry until deeply golden and crisp on one side, then gently turn and cook the other side.
10. Transfer to kitchen paper or a wire rack to drain. Spoon a generous amount of the warm curry sauce onto each plate. Place the crispy eggplant katsu and arrange it over the sauce.
11. Serve with steamed rice and finish with spring onions, sesame seeds or fresh coriander. And if you like a little heat, a few drops of chilli oil are beautiful here too.

A Few Tips

Roast the eggplant until really tender. The contrast between the melting interior and crisp coating is what makes this dish special.

Let the roasted eggplant drain. Too much surface moisture can make it difficult for the flour and panko to stick.

Keep the curry fairly thick. The carrot and sweet potato help naturally thicken the sauce, giving you that luxurious katsu-curry consistency.

Use panko rather than regular breadcrumbs. Those larger flakes give the eggplant its wonderfully craggy, crunchy exterior.

For plating, I particularly love leaving some of the golden curry visible around the eggplant. The combination of the deep golden panko, warm curry, white rice, and a little fresh green garnish makes such a simple but striking plate.

Sometimes vegetarian food really does not need to try too hard. A beautifully cooked vegetable, a crisp coating and a comforting sauce can be more than enough.
