How to make it
For the broth: roast 1.5 kg of beef bones (a mix of marrow bones and soup bones) at 220 °C for 30 minutes, which gives the broth color and aroma. Transfer the roasted bones to a large pot, cover with 3 liters of cold water and add 2 tbsp of apple cider vinegar (this draws minerals out of the bones). Add 1 leek, 1 small bunch of soup vegetables without potato or carrot (or with just 1 small carrot), 2 bay leaves and 1 tsp of black peppercorns. Bring to a boil, skim off the foam, then simmer covered on the lowest heat for 8 to 12 hours. Strain through a fine sieve, season with salt, let cool and either skim off the fat layer that forms or leave it on. For the cup: pour 250 ml of finished broth into a small pot, season with 1/4 tsp of sea salt if needed, bring briefly to a boil, pour into a cup and serve with fresh parsley and a pinch of pepper.
Why bone broth fits keto
Bone broth contains virtually no carbs, but plenty of glycine, proline, glutamine and collagen peptides. The salt supports electrolyte balance, which can be disrupted during the first weeks of a keto diet because low insulin levels cause the body to excrete more sodium. A warm cup of broth around 4 p.m. is an effective tool against the cravings that many keto beginners experience in this phase. Store-bought broths are an emergency fix only, as they often contain sugar, MSG and starch. If you do not cook your own, choose organic broths with a short ingredient list.

How can I vary the broth?
Chicken broth: 1 whole stewing hen replaces the beef bones, tastes lighter, cooking time drops to 4 to 5 hours. Asian style: add 1 cm of grated ginger, a splash of soy sauce (tamari for gluten-free) and 1 spring onion to the cup. With egg yolk: stir 1 fresh egg yolk into the hot (not boiling) cup, which thickens it and makes it more filling. With butter: add 1 tsp of butter to the cup for a creamier, higher-calorie version that works well during intermittent fasting. Spiced cup: 1/4 tsp turmeric, a pinch of pepper and a few drops of lime juice, almost like a savory golden milk.
Tips for foolproof bone broth
- Do not skip the apple cider vinegar, it draws minerals out of the bones.
- Keep the heat low, never a rolling boil, otherwise the broth turns cloudy.
- Skim off the foam during the first 30 minutes to keep the broth clear.
- Add salt only at the end, because the long cooking time concentrates flavor heavily.
- The fat layer on top can be kept covered in the fridge as broth tallow for one week and protects the broth underneath from oxygen.

FAQ
How long does the finished broth keep?
In the fridge 4 to 5 days, frozen in small portions (for example in a silicone mold) up to 3 months. Ice cube trays are practical: each cube holds about 30 ml of broth, perfect for thickening pan sauces or topping up a cup.
Do I need a pressure cooker?
No, but it speeds things up considerably: 90 minutes under pressure equals 8 hours on the stove. Flavor-wise the long simmer is a touch rounder, but in everyday life the pressure cooker plays to its strengths.
Why does my broth taste bland?
Usually it comes down to too little salt or not enough aromatics. Roast the bones first, add the apple cider vinegar, do not forget the soup vegetables and salt generously at the end. If you like, stir 1 tsp of tamari soy sauce into the cup for instant umami depth.
