Let me show you the ultimate lazy meal that's full of flavour and done in 15 mins - an easy and delicious Japanese curry udon.
The cheat: S&B Golden Curry cubes!


Hey, I'm Verna!
About this recipe
Confession: I’ve never made Japanese curry from scratch because I’ve always ever used these S&B golden cubes and they’ve never failed me!
They're how I got through a lot of late nights when I was at engineering school at university.
I did not have the patience to cook things from scratch in those days (and I still regularly feel this way these days) so I've always got a few of these cube lying around my kitchen for emergency meals.
You can of course make this curry and serve it with rice, but as a one person portion, noodles are my go-to because they're the quick to cook and the slurpy texture goes amazingly with the rich and luscious sauce.
Why S&B Golden Curry Cubes?
S&B Golden Curry cubes are a pantry staple in Japanese cuisine, offering an easy way to make rich, flavourful curry.
These curry cubes are available in various heat levels, so you can choose mild, medium, or hot depending on your preference.
You can easily find them in most supermarkets or Asian grocery stores, making this recipe incredibly convenient.
Ingredients
- 100g fresh udon noodles (I got mine from Koya
- 1 S&B Golden Curry cube (easily found in most supermarkets, especially Asian grocery stores)
- 1/2 brown onion, finely diced
- 1 small carrot, julienned
- 350ml water (add more if needed to adjust the sauce consistency)
- 1 stalk of spring onion, thinly sliced
Optional Add-ons:
- 1 soft-boiled egg
- Any source of protein, such as shredded chicken or tofu
Pair it with
Instructions
1. Sauté the Vegetables
Heat a small amount of oil in a pan over medium heat. Add the diced onion and julienned carrot, stirring occasionally. Cook until the onion becomes soft and the carrot is slightly tender—this should take about 3–4 minutes.
2. Make the Curry Sauce
Pour 350ml of water into the pan and bring it to a gentle simmer. Stir in the S&B Golden Curry cube, letting it dissolve completely to form a rich, thick sauce. If the curry becomes too thick, add a splash of water to adjust the consistency.
3. Cook the Udon Noodles
While the curry sauce simmers, cook the fresh udon noodles according to the package instructions—usually just a few minutes in boiling water. Drain and set aside.
4. Combine the Noodles and Curry
Add the cooked udon noodles directly into the curry sauce, tossing them gently to coat evenly. For extra flavour, top with thinly sliced spring onions. You can also add shredded chicken, tofu, or prawns for a more filling meal.
5. Serve and Enjoy!
Serve the curry udon piping hot, optionally topped with a soft-boiled egg for extra richness.

Notes:
- Add Protein: Try shredded chicken, tofu, or prawns to make it a heartier meal.
- Make it Spicy: Add a pinch of chilli flakes or a splash of hot sauce for extra heat.
- Boost the Veggies: Throw in mushrooms, spinach, or pak choi for more nutrients.
- Adjust the Consistency: If the sauce is too thick, simply add more water until you reach your preferred texture.
This quick and flavourful Japanese curry udon is a simple way to enjoy bold, comforting flavours in minutes. Perfect for a cosy night in!
