This is a beef patty built around chopped capsicum (bell pepper), pan-fried and served alongside a quick Japanese vegetable curry with carrot, potato, and onion. The whole meal — burger and curry — comes together in 35 minutes and covers protein, vegetables, and carbs on one plate. It’s a practical weeknight dinner that also stores and reheats well.
Shopping notes
- Japanese curry paste (block or packet): Sold in Asian grocery stores and many mainstream supermarkets. S&B Golden Curry and House Vermont Curry are the most common brands. Half a standard packet is about 2–3 roux blocks. The mild version works well here since the beef patty already carries soy and pepper.
- Capsicum: This is bell pepper. Any colour works — red is sweeter, green is sharper. One medium pepper is enough for the half-pound of beef.
- Soya sauce: Standard light soy sauce. Don’t use dark soy or sweet soy here; they’ll overpower the patty.
- Minced beef: An 80/20 lean-to-fat blend holds together better than extra-lean and stays juicy after pan-frying.
The short version of why this works
Two things carry this recipe. First, the flour acts as a binder alongside the egg, giving the patty enough structure to hold the chopped capsicum without falling apart in the pan — skip the egg in the mix if you want, but the flour alone won’t be enough, so keep both. Second, the Japanese curry paste does the heavy lifting on the sauce: it’s pre-seasoned with spices, thickener, and fat, so you don’t need to build a curry from scratch. Sautéing the onion before adding the liquids pulls out its sweetness and gives the curry a rounder base flavour rather than a sharp, raw-onion edge.
Troubleshooting
- Patties falling apart in the pan: The capsicum releases moisture as it cooks. If your mix feels wet before shaping, add an extra half-tablespoon of flour and chill the shaped patties in the fridge for 15 minutes before cooking.
- Patty not reaching safe temperature: Ground beef must hit 160°F (71°C) internal — use an instant-read thermometer. If the outside is browning too fast, lower the heat and cover the pan for the last 2 minutes rather than cutting into the patty to check.
- Curry too thin after 5 minutes: The paste needs direct contact with heat to thicken. Stir it in off the boil, then return to a steady simmer uncovered. If it’s still thin, give it another 3–4 minutes — don’t add more paste, which makes it salty.
- Curry too thick or catching on the bottom: Add water a quarter-cup at a time and stir from the bottom. Potatoes cut into thin slices break down faster and release starch, which accelerates thickening.
- Capsicum pieces too large in the patty: Chop them small — roughly ¼-inch dice. Larger pieces create air pockets that cause the patty to crack when you flip it.
Make-ahead notes
Both components store well separately. Shaped raw patties can be stacked with parchment between them and refrigerated for up to 24 hours, or frozen for up to 2 months — freeze them on a flat tray first, then transfer to a bag. Cooked patties keep in an airtight container in the fridge for 3 days; reheat in a covered pan over medium-low with a splash of water to prevent drying out, or microwave at 50% power in 45-second intervals until the centre hits 160°F (71°C) again. The vegetable curry actually improves overnight as the potato starch thickens the sauce further. It keeps refrigerated for 4 days and freezes well for up to 3 months. Reheat the curry on the stovetop over low heat, stirring frequently, and add a little water if it has thickened too much.

Instructions
Burger Instructions
- In a large bowl, combine the minced beef, diced capsicum, soy sauce, and pepper. Add the beaten egg and flour, then mix until just combined — do not overwork the mixture or the patties will be tough.¾ lb minced beef, 1 medium red or green capsicum, 1-2 tablespoons soy sauce, ½ teaspoon ground black pepper, 1 medium egg, 2 tablespoons plain (all-purpose) flour
- Divide the mixture into 3 equal portions (about 130g each). Shape into patties roughly 2cm (¾-inch) thick. Press a shallow dimple into the centre of each patty to prevent doming during cooking.
- Heat a non-stick skillet over medium-high heat with a thin film of oil. Cook the patties for 5 minutes per side until deeply browned and the internal temperature reaches 160°F / 71°C. Rest for 2 minutes before serving.
Vegetable Japanese Curry Instructions
- Heat a medium saucepan over medium heat and add 2 tablespoons of olive oil.2 tablespoons olive oil
- Add the onion wedges and sauté for 3–4 minutes until softened and lightly translucent.1 medium yellow or red onion
- Add in the carrot and cook for 3 minutes.1 medium carrot
- Pour in the water, add the potato cubes, and bring to a boil. Reduce heat to medium-low, cover, and simmer for 10–12 minutes until the potatoes are fork-tender.3 cups water, 2 small waxy potatoes
- Turn off the heat. Break the curry roux blocks into the pot and stir until fully dissolved. Return to low heat and simmer for 3–5 minutes, stirring frequently, until the curry thickens to a glossy, coating consistency.½ packet Japanese curry roux blocks
- Thinly slice the Japanese cucumber and arrange alongside the burger and curry as a fresh garnish.1 medium Japanese cucumber
- On the dinner plate, serve the desired portion of rice. Place the prepared beef patties alongside and ladle the curry over or beside them. Add any additional toppings you like — a fried egg, pickled ginger, or a drizzle of Kewpie mayo all work well here. Serve hot.2 cups cooked rice or Japanese rice with quinoa

Your questions, answered
Can I use a different protein instead of minced beef?
Yes — ground chicken or turkey works as a direct swap. If you use poultry, cook the patties to an internal temperature of 165°F (74°C) and expect no pink at the centre.
Do I need to serve this with rice, or can I put the patty in a bun?
Either works fine. A bun turns this into a more conventional burger; rice makes it a full Japanese-style plate meal. If you go the bun route, serve the curry as a dipping sauce or side bowl rather than pouring it over the burger.
Can I make the patties ahead and cook them from frozen?
Yes. Cook frozen patties directly from the freezer over medium heat, adding roughly 3–4 extra minutes per side. Always verify the internal temperature reaches 160°F (71°C) before serving.
What if I can’t find Japanese curry paste?
A mild Indian curry paste (like korma) is the closest substitute in terms of convenience — use about 2 tablespoons. The flavour profile will differ slightly but the method stays the same.
Can I add other vegetables to the curry?
Absolutely. Zucchini, mushrooms, or frozen peas all work well and don’t change the cook time significantly. Add harder vegetables like sweet potato at the same stage as the carrot, and softer ones like peas in the last 2 minutes.
