Place the herbs, bay leaf and peppercorns on a piece of cheesecloth or the dark green top of a leek.

Fold up the sides around the ingredients.

Secure well with kitchen twine.

Place the turkey bones, onion, carrot, celery and bouquet garni into a large pot or Instant Pot and fill with water until 2" over the ingredients. If using the Instant Pot, make sure the ingredients do not go over the fill line.

For stove top: Bring to a boil, then immediately reduce the heat to a simmer and cook for 3 – 3 1/2 hours, skimming the fat from the top occasionally. For Instant Pot turkey stock: cook at high pressure for 1 – 1 1/2 hours, then quick release the pressure. Remove the carcass, vegetables and bouquet garni and discard.

Strain the stock through a fine mesh sieve into a large bowl and cool completely. Skim any fat off of the top and store in an air tight container in the refrigerator for up to 5 days or freeze for up to 3 months.
