Introduction: The Low-Carb Dilemma
Is curry low carb? If you’re a Japanese food lover following a low-carb diet, this question has probably crossed your mind more than once. Japanese curry is rich, flavorful, and comforting, but is it low-carb friendly? Or is it another dish to sadly remove from your meal plan?

For those who love chicken katsu curry, that crispy golden cutlet drenched in velvety curry sauce, we’ll break down its carb content and show you how to make it low carb without sacrificing taste. Get ready to learn everything you need to know about enjoying Japanese curry while sticking to your low-carb diet!
What Makes Japanese Curry High in Carbs?
Japanese curry is different from Indian or Thai curry—it’s thicker, slightly sweet, and has a rich umami flavor. But here’s the problem: most Japanese curry sauces contain flour, sugar, and starchy vegetables (like potatoes and carrots), which increase the carb count significantly.

A standard serving of Japanese curry with rice can have 80-100 grams of carbs! Not exactly keto-friendly. The main culprits include:
- Roux (thickening agent): Made from flour and butter, it gives the curry its thick texture but adds unnecessary carbs.
- Sugar: Many store-bought curry cubes contain sugar to enhance the flavor.
- Rice: The classic pairing with curry is white rice, which is high in carbs.
- Potatoes & Carrots: Commonly found in Japanese curry, these vegetables add both texture and extra carbs.
So, does that mean you have to give up on curry forever? Absolutely not! With a few adjustments, you can enjoy a delicious low-carb Japanese curry.
How to Make Japanese Curry Low Carb

If you’re looking for a way to enjoy Japanese curry without derailing your low-carb diet, here are some simple swaps to make it work:
1. Ditch the Roux – Use a Low-Carb Thickener
The classic curry roux is made with flour, but you can replace it with:
- Almond flour – Adds thickness without carbs.
- Xanthan gum – A tiny bit goes a long way to keep that velvety texture.
- Coconut flour – A great option for a subtle sweetness without sugar.
2. Choose Low-Carb Vegetables
Instead of starchy potatoes and carrots, go for:
- Daikon radish – Mimics the texture of potatoes with fewer carbs.
- Zucchini & cauliflower – Adds volume and absorbs the curry sauce well.
- Eggplant & mushrooms – Great for extra umami flavor.
3. Swap the Rice for Keto-Friendly Options
Rice is a major carb source in Japanese curry, but you can replace it with:
- Cauliflower rice – The go-to low-carb substitute.
- Shirataki rice – Made from konjac, it’s zero carbs and absorbs curry sauce perfectly.
4. Make a Low-Carb Chicken Katsu Curry
For chicken katsu curry lovers, the crispy fried cutlet is a must-have. But traditional breadcrumbs (panko) are packed with carbs. Try:
- Crushed pork rinds – Super crispy and zero carbs.
- Almond flour – A great substitute for a crunchy texture.
- Parmesan cheese – Adds an extra layer of flavor with fewer carbs.
