Aubergine Japanese curry is a Japanese-style curry rice dish made with tender eggplant, vegetables and a thick, gently spiced curry sauce, usually served over steamed rice. Japanese curry has many household variations; this version browns the aubergine first, then simmers it with carrots and potatoes for a hearty, comforting bowl.
Ingredients
- 1 large aubergine (about 1 lb / 450 g), cut into 1-inch (2.5 cm) chunks
- 2 tablespoons (30 ml) neutral cooking oil, divided
- 1 medium yellow onion (about 7 oz / 200 g), thinly sliced
- 1 medium carrot (about 4 oz / 115 g), peeled and cut into ½-inch (1.25 cm) pieces
- 2 small waxy potatoes (about 9 oz / 250 g total), peeled if desired and cut into ¾-inch (2 cm) chunks
- 2 cloves garlic (about 6 g), finely chopped
- 1 teaspoon (5 g) finely grated fresh ginger
- 3 cups (710 ml) low-sodium vegetable broth or water
- 1 small apple (about 5 oz / 140 g), peeled and finely grated
- 3.5 oz (100 g) Japanese curry roux blocks, mild or medium, broken into pieces; use the package amount for four servings if it differs
- 1 tablespoon (15 ml) soy sauce
- 1 teaspoon (5 ml) Worcestershire sauce, optional
- ½ teaspoon (2.5 g) fine salt, plus more to taste
- ¼ teaspoon (0.5 g) freshly ground black pepper
- 4 cups (720 g) cooked Japanese short-grain rice, for serving
Instructions
- Prepare the vegetables, 20 minutes. Cut the aubergine, onion, carrot and potatoes as directed, then mince the garlic and grate the ginger and apple. Break the curry roux into small pieces so it will dissolve evenly later. If the aubergine is especially large, cut any thick pieces in half so the chunks are similar in size.
- Brown the aubergine, 10 minutes. Warm 1 tablespoon (15 ml) oil in a wide, heavy pot or Dutch oven over medium-high heat. Add the aubergine in a single layer, working in batches if needed, and season with a pinch of the salt. Cook for about 8 to 10 minutes, turning the pieces until several sides are golden and the flesh has softened but still holds its shape. Transfer to a plate. Avoid crowding the pot: piled-up pieces steam and become soft before they brown.
- Soften the aromatics and vegetables, 8 minutes. Add the remaining 1 tablespoon (15 ml) oil to the pot and reduce the heat to medium. Add the onion and cook for 3 minutes, stirring, until it starts to soften. Add the carrot, potatoes, garlic and ginger. Stir for about 5 minutes, scraping up any browned aubergine bits from the base. Keep the garlic moving so it does not scorch.
- Simmer the potatoes and carrot, 15 minutes. Pour in the broth or water and stir in the grated apple, soy sauce, Worcestershire sauce if using, remaining salt and pepper. Bring the mixture to a gentle boil, then lower the heat, cover and simmer for 15 minutes. Keep the liquid at a steady, gentle bubble rather than a hard boil, which can break up the potatoes before they are tender.
- Add the aubergine, 5 minutes. Return the browned aubergine and any juices on the plate to the pot. Simmer uncovered for about 5 minutes, stirring gently once or twice, until the carrot and potato are nearly tender and the aubergine is soft. Check a potato piece with a fork; it should be easy to pierce but not falling apart.
- Thicken with the curry roux, 2 minutes. Turn off the heat. Stir in the broken roux pieces a little at a time until dissolved. Return the pot to low heat and simmer gently for about 2 minutes, stirring often, until the sauce is glossy and thick enough to coat a spoon. Do not let it boil vigorously, as roux can catch on the bottom. Taste and adjust with a little salt or soy sauce if needed. Serve hot over the cooked rice.
Tips
- Brown the eggplant in batches. Aubergine absorbs oil readily, but a hot pan and space between pieces help it brown rather than turn greasy. Add a small splash of oil only if the pan is completely dry; avoid pouring in extra oil all at once.
- Choose the right roux amount. Japanese curry blocks vary by brand and strength. The stated 3.5 ounces (100 g) is a practical amount for four servings, but check the packet’s serving directions and start with slightly less if you prefer a looser, milder sauce. Add more after tasting if needed.
- Use the apple as a balance, not a sweetener. Grated apple melts into the sauce and rounds out the savory spices. If you do not have one, leave it out or use 1 tablespoon (15 ml) unsweetened applesauce; the curry will taste a little less fruity.
- Check the roux ingredients. Curry blocks are convenient and widely sold in Japanese and many international grocery stores, but they often contain wheat and may contain dairy or other ingredients. For a gluten-free version, use a clearly labeled gluten-free Japanese curry roux; ordinary curry powder alone will not thicken the sauce in the same way.
Serving Suggestions
Spoon the curry beside or over hot Japanese short-grain rice, with enough sauce to settle into the grains. A shallow bowl makes it easy to keep the rice and curry distinct while still getting some of each in every bite. If you want to prepare rice from scratch, start it before the curry so both are ready together; the rice quantity listed is cooked weight, approximately four generous portions.
For a crisp, tangy contrast to the rich sauce, serve Japanese pickled vegetables such as fukujinzuke or rakkyo on the side. A simple cucumber salad dressed with rice vinegar also works well. Add sliced scallions for freshness, or offer chili oil or shichimi togarashi at the table for anyone who wants extra heat. The curry is filling on its own, so a small salad or quick pickle is usually enough alongside it.
Variations
Make it vegan. Use water or vegetable broth and check that the curry roux contains no dairy, honey or animal-derived ingredients. Roux recipes differ, so the package label matters. A vegan-certified Japanese curry block is the easiest option and keeps the familiar thick texture.
Add mushrooms or other vegetables. Replace some of the potato with 1 cup (70 g) sliced mushrooms, or add 1 cup (130 g) diced zucchini with the aubergine. Mushrooms bring a deeper savory flavor; zucchini softens quickly, so add it near the end rather than simmering it for the full 15 minutes.
Make it spicier. Choose a hot curry roux, or stir in ¼ teaspoon (1 g) cayenne or a little chili oil at the end. Increase the heat gradually, since roux spice levels vary and the sweetness of the apple can make a mild curry taste especially gentle.
Make a roux-free version. If curry blocks are unavailable, cook 2 tablespoons (28 g) butter or neutral oil with 2 tablespoons (16 g) all-purpose flour for 2 to 3 minutes, stirring until smooth and lightly golden. Stir in 1 tablespoon (6 g) Japanese curry powder, then whisk this mixture into the simmering broth. It will have a less rounded, somewhat more powder-forward flavor than block roux; add salt and a small splash of soy sauce to taste. For a gluten-free version, use a suitable gluten-free flour and confirm the curry powder is gluten-free.
Storage and Reheating
Cool leftovers promptly and refrigerate them within 2 hours of cooking in a covered, shallow container. Keep the curry and rice in separate containers if possible; rice can become dense as it sits, and separating them makes it easier to reheat each evenly. Refrigerated curry keeps for 3 to 4 days. The sauce thickens as it chills, so loosen it with a tablespoon or two of water or broth when reheating.
Reheat only the portion you plan to eat in a saucepan over medium-low heat, stirring often, or microwave it in a covered, microwave-safe dish, stirring partway through. Heat leftovers to 165°F (74°C), the USDA FSIS safe temperature for reheated leftovers. If the curry has been frozen, thaw it overnight in the refrigerator before reheating; use within about 2 to 3 months for best quality. Potatoes and aubergine may soften further after freezing, but the flavor remains suitable for a quick meal.
Frequently Asked Questions
Can I use a different type of eggplant? Yes. Japanese or Chinese eggplants are slender and tender, while globe aubergines are larger and have thicker skin. Use about 1 pound (450 g) total, cut into similar-sized pieces; if using smaller eggplants, you can leave their tender skins on.
Do I need to salt aubergine before cooking? Not for this recipe. Modern aubergines are generally not as bitter as older varieties, and browning them directly works well. If your aubergine tastes bitter or has many large seeds, you can salt the cut pieces for 20 minutes, rinse and pat them very dry, but that adds time and is not necessary for most fruit.
Why did my curry turn out too thick? Curry roux thickens as it cools, and different blocks have different starch levels. Stir in hot water or broth a little at a time until the sauce reaches the consistency you like. If it is too thin, simmer it gently for a few minutes before serving, stirring often so it does not stick.
Can I make the curry ahead? Yes. Make it a day ahead, cool it promptly and refrigerate it, then reheat it gently with a splash of water or broth. The flavors settle as it rests, though the potatoes and aubergine will soften slightly. Cook rice fresh when possible, or refrigerate it separately and reheat it thoroughly.
What can I use instead of Japanese curry blocks? The roux-free option in the variations section uses butter or oil, flour and Japanese curry powder. It makes a good pantry substitute, but the result is less sweet, less glossy and often less complex than curry made with packaged roux. Taste carefully and adjust the salt because curry powders and broths vary.
