Homemade bone broth takes a long time to develop all of the beneficial nutrients. The recommended simmer time is 12-24 hours at a temperature between 180-200°F (82-93°C). This will help convert all the collagen into gelatin. The minerals from the bones will also be released completely. The flavor compounds will form some rich and complex flavors. The heat-sensitive nutrients will all stay intact when cooked at specific temperatures.

Collagen Conversion

  • Minimum 12 hours below boiling point
  • Converts collagen to bioavailable gelatin
  • Forms characteristic gelling texture when cooled

Mineral Extraction

  • Calcium magnesium release after 8+ hours
  • Vinegar increases mineral yield 40%
  • Bone density determines extraction time

Flavor Development

  • Maillard reactions create complex flavors
  • Vegetable additions enhance taste profile
  • Consistent low heat prevents bitterness

Use smart techniques to streamline preparation. Roast bones at 400°F (204°C) for 30 minutes, then simmer for the recommended time. This procures a deeper flavor and will save you time on the stovetop. Using a slow cooker allows for a consistent temperature throughout the night. Pressure cooking reduces active cooking time to two hours, but may not achieve as much gelatin. While cooking, stir occasionally to ensure everything heats evenly.

Keep an eye on the key completion indicators. Well-cooked broth gels well when refrigerated. Bones crumble in the broth, indicating the extraction of minerals. The liquid volume is reduced by approximately one-third to intensify the flavor. Vegetables break down completely into the broth. The top has a golden layer of fat, which indicates a nutritious broth.

There are unique considerations that affect preparation time. Beef bones require more time than poultry, typically 18-24 hours. Fish bones need only 4-6 hours to avoid a bitter flavor. Adding vinegar will reduce the time required to extract minerals. Altitude increases the boiling point and will lengthen the simmering time required. Adjust your expectations according to these variables.
