  • 1/2 lb Ground Pork fat>20% preferred
  • 1/2 lb Ground Beef fat>20% preferred
  • 1/2 tbsp Butter
  • 1/8 Onion
  • 1 Clove Garlic
  • 0.5 oz  Unflavored Pork Rinds 1 tbsp if using Pork Panko
  • 1/2 tsp Salt
  • 1/8 tsp Black Pepper
  • 1 Egg
  • 1 1/2 tbsp Half & Half
  • 1/4 tsp Nutmeg


  • 1/2 Cup Almond Flour
  • 2 Eggs
  • 3 oz  Unflavored Pork Rinds 1/3 Cup if using Pork Panko


  • 2 tbsp Sugar Free Ketchup
  • 1 1/2 tbsp Worcestershire Sauce
  • 1 tbsp Oyster Sauce
  • 1 tsp Monkfruit Erythritol Blend


  • Gather all the ingredients.
  • Dice onions. In a medium sized fry pan, add 1/2 tbsp butter on medium heat. Once butter is melted, add onion, cook until browned and set aside. Should take around 2-3 minutes.
  • Grate garlic with a grinder or a garlic press. Put into a large mixing bowl.
  • Pour Unflavored Pork Rinds into a food processor and pulse until ground into very fine. You can also use your hands to crush the pork rinds if you don’t have a food processor, but we strongly recommend using a food processor. Place 1 tbsp of crushing pork rinds into the mixing bowl and set the remaining aside.
  • In the mixing bowl, add ground pork, ground beef, salt, pepper, egg, half & half, nutmeg, cooked onions from step 2). Combine with hands until mixed well.
  • Take 1/4 of the mix and throw from one hand to another while gently cupping the mix with the palm and hand forming a ball. Place the ball onto a plate and press down on it with the palm of your hand to form a patty. The patty should be around 1 inch thick. Afterwards, take your thumb and gently press and make an indent in the middle of the hamburger patty. This ensures the hamburger will retain its shape during the cooking process (otherwise it will expand upwards). Repeat until all the mix is used up.
  • Fill 1 mixing bowl with Almond Flour, 1 mixing bowl with beaten eggs, 1 mixing bowl with the reaming crushed Unflavored Pork Rinds/Pork Panko from step 4).
  • Take a patty and dip in the following order: Almond Flour > eggs > Unflavored Pork Rinds/Pork Panko. Once coated, place into air fryer tray and air fry for 13-16 minutes at 360F or until internal temp reaches 160F.
  • In a small mixing bowl, combine Sugar Free Ketchup, Worcestershire Sauce, Oyster Sauce and Monkfruit Erythritol Blend. Mix well and set aside.
  • Once menchi katsu are air fried, transfer to serving plate and enjoy with keto tonkatsu sauce from step 9)!
