It’s cooked for 4-6 hours at a gentle simmer for the connective tissue to break down and the deep rich flavour to develop in the meat stock.
Dr Natasha Campbell-McBride creator of the GAPS Diet recommends consuming lots of meat stock daily! The more meat stock consumed, the quicker the gut lining heals! Think of meat stock as the glue that seals up your intestinal lining.
This nourishing GAPS Oxtail Soup recipe offers a delicious addition to your GAPS Diet meal plan. Suitable for Stage 6 of the GAPS Introduction Diet due to the fibrous nature of the celery pieces though it can be modified to be eaten from Stage 2, see variation details later in the post.

To get the maximum healing benefits that this soup has to offer you’ll want to consider the quality of ingredients and where you source them from. Use the best quality oxtail that you can afford or is available to you.
- Good: Free range

Tips for making Oxtail Soup for Gut Healing
- Choose filtered water. Chlorine in city tap water
- Skim the top – Once the oxtail reaches a simmer, you may need to skim the top of the soup for impurities aka skim the scum.
- Oxtail soup tends to be a little too oily for some people, so you can emulsify the fat in the cooking liquid so it doesn’t float on top. At the end of the cooking time remove the fat on top plus 1-2 cups of the cooking liquid and blend with an immersion blender before returning to the pot.
