Keto Pork Belly is a fantastic dish that shines when served with crispy green onion, zesty lime wedges and a sprinkle of flaky salt. These succulent bites work equally well as a main course or a crowd-pleasing appetizer.
This version draws inspiration from ramen-style pork belly and the Japanese technique of poaching meats in a shallow bath of flavorful liquid. Traditional soy sauce isn’t ideal for everyone on a ketogenic diet because it can contain gluten and soy compounds some people prefer to avoid. If you tolerate soy or have already tested it through an elimination process, feel free to use it or substitute liquid aminos.

With this method the pork belly becomes super crispy on one side while remaining juicy on the other. The contrast is achieved by finishing the oven-roasted pork with a quick high-heat sear in a frying pan, which gives an uneven, satisfying crunch and concentrated salty flavor that you can’t get from pan-frying alone.
Soaking or briefly marinating the pork allows the meat to absorb the flavors from the liquid while staying moist in the oven. This technique is especially effective for proteins that take on bold flavors, such as pork and chicken.

Ingredients
- 500 g Pork Belly Skin On
- 1/4 Cup Liquid Aminos or Soy Sauce
- 1/4 Cup Water
- 2 Cloves Garlic Crushed
- 2 Tablespoons Erythritol
- 2 Tablespoons Oyster Sauce
- 1 teaspoon Smoked Paprika
- 1 Tablespoons Peppercorns
- 5 Shallots Sliced
- Lime – To Taste
Instructions
-
Place the pork belly in a large flat dish skin-side up.
-
In a small bowl, combine liquid aminos (or soy sauce), water, crushed garlic, erythritol, oyster sauce, smoked paprika and peppercorns.
-
Pour the mixture into the dish but keep it shallow so the liquid doesn’t reach the skin.
-
Cover and refrigerate overnight to let the pork absorb the flavors.
-
Preheat the oven to 180°C (355°F). Place a rack on a foil-lined baking tray and pour ½ cup of water into the pan.
-
Remove the pork from the marinade, place it on the rack, season the skin generously with salt, and roast for 40 minutes.
-
Increase the oven temperature to 200°C (390°F) and roast another 30 minutes, or until the top is crisp.
-
Remove the pork from the oven and cut into roughly 2-inch cubes. In a hot frying pan, sear each side until extra crispy.
-
Add some reserved marinade to the pan and reduce for 3–5 minutes. Add sliced shallots and cook for about 1 minute in the bubbling sauce.
-
Remove from the pan and serve immediately with fresh lime wedges.
