Step‑by‑Step Instructions for Crispy Eggplant ‘Katsu’
Step 1: Prepare Eggplant
Begin by washing and trimming the Chinese eggplants. Slice them diagonally into 3/4 to 1-inch thick pieces for optimal crispiness. Arrange the eggplant slices on a baking sheet and lightly salt them, allowing them to sit for about 15 minutes to draw out moisture. This step enhances the flavor and helps achieve a firmer texture when frying.
Step 2: Make Batter
In a mixing bowl, combine the all-purpose flour, cornstarch, baking powder, and salt. Gradually whisk in 1/2 cup plus 2 tablespoons of water, mixing until the batter becomes smooth and thick enough to coat the back of a spoon. Set the batter aside, ensuring it remains ready for dipping the eggplant slices into the crispy eggplant ‘katsu’ coating.
Step 3: Prepare Breadcrumbs
Pour the Japanese breadcrumbs into a shallow bowl and set aside. This step is crucial for creating the delightful crunchy exterior of your crispy eggplant ‘katsu.’ Make sure the breadcrumbs are evenly spread out in the bowl to facilitate an even coating process later on.
Step 4: Coat Eggplant
Employ a two-hand technique: one hand for dipping the eggplant slices into the batter and the other for coating them with breadcrumbs. Start by immersing each eggplant slice in the batter, allowing any excess to drip off before transferring them to the bowl of breadcrumbs. Gently press the breadcrumbs onto the slices to ensure an even and thorough coating for that perfect crispy texture.
Step 5: Heat Oil
In a deep frying pan or wok, pour enough neutral oil to submerge the eggplant slices—aim for about 2 inches in height. Heat the oil over medium-high heat until it reaches approximately 350°F (180°C). To test the oil, drop in a small piece of breadcrumb; it should sizzle and rise to the surface instantly, indicating the oil is ready for frying.
Step 6: Fry Eggplant
Carefully add the breaded eggplant slices to the hot oil, frying them in batches to avoid overcrowding. Cook each piece for about 2-3 minutes on one side until golden brown, then flip and fry for another 2-3 minutes on the other side. The crispy eggplant ‘katsu’ should achieve a deep golden hue and a satisfying crunch when fully cooked.
Step 7: Drain Oil
Once the eggplant slices are fried to perfection, use a slotted spoon to carefully remove them from the oil. Place them on a cooling rack or a plate lined with paper towels to drain excess oil. Avoid covering them as this will help maintain their crispiness while you prepare the next batch.
Step 8: Serve
Your crispy eggplant ‘katsu’ is now ready to be enjoyed! Serve it immediately while hot, alongside steaming short grain rice and a bowl of flavorful Japanese curry for dipping. This delightful combination creates a wholesome, satisfying meal that’s sure to impress family and friends.

Crispy Eggplant ‘Katsu’ Recipe FAQs
What is the best way to select ripe eggplants?
Absolutely! When choosing eggplants for your crispy eggplant ‘katsu,’ look for ones that are firm to the touch with smooth, shiny skin and without any dark spots or blemishes. The smaller and slimmer the eggplant, the less bitter it tends to be. Opt for Chinese eggplants if available, as they have a tender texture and mild flavor that’s perfect for this dish.
How do I store leftover crispy eggplant ‘katsu’?
To maintain the texture and flavor of your crispy eggplant ‘katsu,’ place any leftovers in an airtight container and refrigerate for up to 3 days. This will keep them fresh. When you’re ready to enjoy them again, I recommend reheating in an air fryer or oven to restore that delightful crunch!
Can crispy eggplant ‘katsu’ be frozen?
Yes, indeed! To freeze your crispy eggplant ‘katsu,’ first lay them in a single layer on a baking sheet and freeze until solid. This prevents them from sticking together. Then, transfer the frozen pieces to an airtight container or freezer bag for up to 2 months. When you’re ready to eat them, simply reheat in an air fryer or bake them in the oven as described previously.
What if my batter is too thick or too thin?
If your batter seems too thick, just add a little more water, one tablespoon at a time, until you reach a smooth, pourable consistency. If it’s too thin, sprinkle in a bit more flour or cornstarch. For crispy eggplant ‘katsu,’ you want the batter to be thick enough to cling to the eggplant but not so thick that it overpowers the delicate flavor of the vegetable!
Are there any dietary considerations for pets or allergies?
Absolutely! While crispy eggplant ‘katsu’ is vegan and generally safe for human consumption, be cautious about sharing with pets. Eggplants belong to the nightshade family and can cause issues for some animals, especially cats and dogs. Additionally, if cooking for others, be mindful of gluten allergies—ensure you’re using certified gluten-free breadcrumbs and flours for those who need them.
