How to make Katsu Chaffle Chicken Sandwich?

Directions

  1. Start by whisking together ketchup, Worcestershire sauce, oyster sauce, and sweetener in a mixing bowl to prepare the flavorful katsu sauce.
  2. Next, season the chicken with salt and black pepper, coat it with flour, dip it in beaten egg, and then coat it with your preferred choice of panko.
  3. Deep fry the chicken for approximately 3-4 minutes per side until it reaches an internal temperature of 165°F.
  4. Meanwhile, beat eggs in a mixing bowl to prepare the chaffle buns. Preheat a mini waffle iron, sprinkle cheese on it, followed by the beaten eggs, and another sprinkle of cheese. Cook the chaffles for 3-4 minutes until they turn golden brown and crispy.
  5. Finally, assemble the sandwich by placing the chaffles or bread of your choice between the fried chicken patties, and top it off with the flavorful katsu sauce.

  1. Mmmm, I miss the “tonkatsu sando” from 7-11 or Lawsons. A tonkatsu pork tenderloin with shredded cabbage and tasty sauce…Heaven! The bread was always nice and fresh I’ll have to admit 🙂

      Hey Tony! I love bentos from 7-11, lawson, famima and something I look forward every time I go to Japan! The katso sandos, salads, and the oden! Which reminds me that we have to get a low carb keto oden recipe this winter!

  2. Is the 41 carbs listed a typo? I want to try this, but 41 carbs is too much for me.

    • LowCarbingAsian

      Hello! I had to actually double-check this myself! So it is correct and it’s 41g carbs, but 1) it’s also 37g fiber, so the net carb is actually only 4g. 2) Most of the carbs are coming from the optional psyllium husk coating. So if you just use the pork rinds instead, it will be around 4g carb total. Hope that helps!
