This sweet, savory and tangy low carb tonkatsu sauce takes all your Japanese deep-fried dishes to the next level! Using only a few ingredients, this simple and easy Japanese staple is a sauce worth making for all your deep-fried favorites!
In my opinion, the hard thing about being keto or low carb is that many sauces are always off-limits due to their high sugar content.
But never in a million years would I ever imagine having tonkatsu pork cutlet without tonkatsu sauce… am I right?
This is why I have made it my low carb keto mission to make as many sauces, low carb friendly as I can, just like this Japanese classic tonkatsu sauce!
Just a note, for this tonkatsu sauce to taste authentic, I did use oyster sauce that contains sugar, so use it at your own discretion depending on your diet plan. You can leave it out if your strict keto, but it will alter the taste of the sauce.
What is tonkatsu sauce?
Traditionally, tonkatsu sauce is made up of many ingredients including sugar, vinegar, tomato paste, apple puree, carrots, onions, lemon juice and spices. It’s sold in a bottle at most Japanese markets and served with all kinds of deep fried foods.
How do you make tonkatsu sauce low carb?
As mentioned above for this recipe, I did use a small amount of oyster sauce, which does contain sugar but to limit the carbs for the rest of the sauce, I used sugar-free ketchup and monkfruit.
How long does tonkatsu sauce last in the fridge?
If kept in an air tight container, the sauce should last numerous months in the refrigerator.
What to serve with tonkatsu sauce?
Tonkatsu sauce goes well with deep-fried dishes such as deep-fried pork cutlets, deep-fried chicken, deep-fried shrimp, deep fried tofu or even just on a bed of cabbage.
