Crispy Eggplant ‘Katsu’ Ingredients
• Get ready to create magic with these essential components!
For the Batter
- Chinese Eggplants (17.5 oz) – The star of this dish, providing a creamy texture; you can substitute with American eggplants if needed.
- All-Purpose Flour (1/2 cup) – This forms the batter; swap it with gluten-free flour for a gluten-free option.
- Corn Starch (1.5 tbsp) – Ensures a light and crispy batter; arrowroot starch works well if you prefer.
- Baking Powder (1 tsp) – Adds fluffiness to the batter for that perfect crunch.
- Salt (1 tsp) – Elevates the flavor of the batter; adjust according to your taste.
- Water (1/2 cup + 2 tbsp) – Necessary for achieving the right consistency; feel free to add more until you reach a pancake batter-like texture.
For the Coating
- Neutral Oil – Essential for frying; high smoke-point oils like canola or grapeseed are ideal.
- Bread Crumbs (2 cups) – The crispy coating; using Japanese panko will give you the best texture, but regular breadcrumbs can work too.
For Serving
- Japanese Curry – Complements the eggplant beautifully; feel free to choose any curry that you love.
- Steamed Short Grain Rice – A comforting side; you can substitute with quinoa to mix things up.

Step‑by‑Step Instructions for Crispy Eggplant ‘Katsu’
Step 1: Prepare Eggplant
Begin by slicing the Chinese eggplants into 3/4 to 1-inch thick pieces at an angle. This technique helps enhance the surface area, ensuring a deliciously crispy texture in your Crispy Eggplant ‘Katsu’. Arrange the eggplant slices on a clean surface, allowing them to breathe while you prepare the batter.
Step 2: Make Batter
In a mixing bowl, combine the all-purpose flour, corn starch, baking powder, and salt. Gradually whisk in 1/2 cup of water until the batter reaches a smooth and thick pancake-like consistency. Adjust with additional water if needed. This batter will coat the eggplant slices, providing that essential crunch you desire in your Crispy Eggplant ‘Katsu’.
Step 3: Coat Eggplant
Dip each eggplant slice into the batter, ensuring it’s fully coated. Next, transfer the battered eggplant to a plate filled with breadcrumbs and gently press to secure a generous layer of crispy coating. Use one hand for the wet batter and the other for the dry ingredients to maintain a tidy cooking space throughout this process.
Step 4: Heat Oil
In a large frying pan, pour enough neutral oil to cover the bottom and heat over medium-high until it reaches approximately 350°F (180°C). To test if the oil is ready, drop a few breadcrumbs into the oil—if they sizzle and float, you’re all set to fry your Crispy Eggplant ‘Katsu’ to perfection.
Step 5: Fry Eggplant
Carefully place the coated eggplant slices in the hot oil without overcrowding the pan. Fry for 2 to 3 minutes on each side, until they turn a beautiful golden brown and become crisp. Keep a close eye on them to avoid burning and ensure even cooking for that glorious crunch.
Step 6: Drain
Once the eggplant slices are perfectly fried, use a slotted spoon to transfer them onto a cooling rack set over a baking sheet. This setup allows excess oil to drain off while keeping them crispy. Avoid covering them as this can make the coating soggy.
Step 7: Serve
Plate your Crispy Eggplant ‘Katsu’ alongside Japanese curry and steamed short grain rice for a comforting meal. Alternatively, drizzle with tonkatsu sauce and add a side of shredded cabbage for a refreshing contrast. Each bite is sure to be a delightful culinary journey!
