Step‑by‑Step Instructions for Crispy Eggplant ‘Katsu’
Step 1: Slice the Eggplant
Begin by preparing the Chinese eggplant, slicing it into 3/4 to 1-inch thick pieces. Make sure to angle your cuts slightly to maximize the surface area, which allows for even crisping. Lay the slices flat on a clean cutting board, and take a moment to admire the beautiful violet skin before moving on to the batter.
Step 2: Prepare the Batter
In a mixing bowl, whisk together the all-purpose flour, corn starch, baking powder, and salt until well combined. Gradually add enough water to achieve a thick pancake-like consistency, ensuring there are no lumps. This batter will coat your eggplant slices perfectly, creating that irresistible crunch we’re aiming for in our Crispy Eggplant ‘Katsu.’
Step 3: Set Up the Breadcrumb Station
In a separate bowl, pour in the panko breadcrumbs, ready for coating the batter-dipped eggplant. This step is crucial for giving your katsu its signature crispy texture. Having the breadcrumbs nearby will streamline the process, keeping your kitchen organized and making it easier to achieve that perfect coating.
Step 4: Coat the Eggplant
Take your first eggplant slice and dip it into the batter, ensuring it’s fully covered, then lift it out and let excess batter drip off. Next, transfer the eggplant to the bowl of panko breadcrumbs and coat it thoroughly on both sides. Using one hand for wet and one for dry helps keep the process clean and efficient.
Step 5: Heat the Oil
In a large frying pan, heat your neutral oil over medium-high heat until it reaches about 350°F (180°C). To check if the oil is ready, sprinkle a few breadcrumbs into the pan; if they sizzle and rise to the surface, you’re good to go! This hot oil will ensure your katsu turns golden brown and crispy.
Step 6: Fry the Eggplant
Gently place a few battered eggplant slices into the hot oil, being careful not to overcrowd the pan. Fry for about 2-3 minutes on each side, or until they are a beautiful golden brown and have that irresistible crispy appearance. Once cooked, carefully remove each piece and lay it on a cooling rack to maintain its crunch—avoid placing them on paper towels.
Step 7: Serve and Enjoy
Your Crispy Eggplant ‘Katsu’ is now ready! Serve it warm alongside steaming short-grain rice and a side of savory Japanese curry, or enjoy it as a delightful standalone dish with tonkatsu or teriyaki sauce. Take a moment to appreciate the delightful textures and flavors that come together in each bite.

Crispy Eggplant ‘Katsu’ Recipe FAQs
What type of eggplant is best for this recipe?
Chinese eggplant is the foundation of this dish, offering a delicate texture and flavor that’s perfect for katsu. If you can’t find Chinese eggplant, American eggplant can also be used as a substitute. Look for firm eggplants without dark spots or wrinkling to ensure freshness and ripeness.
How should I store leftover crispy eggplant ‘katsu’?
To keep your delicious katsu fresh, store any leftovers in an airtight container in the refrigerator for up to 2 days. While the katsu will lose some of its crispiness, it can still be enjoyed as a tasty treat! For best results, reheat in an air fryer or oven to retain any crunch.
Can I freeze crispy eggplant ‘katsu’? How do I do it?
Absolutely! To freeze your crispy eggplant ‘katsu’, first lay the individual pieces on a baking sheet in a single layer and freeze until solid, about 1-2 hours.

Ah, the dreaded sogginess! To avoid this, ensure that your oil is heated to 350°F (180°C) before frying your eggplant.
