Preheat oven to 400 degrees.
Halve your onion and arrange the onion, turkey back, neck and leftover pieces on a baking sheet.
Roast leftover turkey pieces for 45 minutes in the oven at 400 degrees. I used the neck, back, carcass and other scraps. See how I broke down and processed my turkey to cook the pieces individually in the video linked below.
Once scraps are roasted, scrape the drippings and scraps into a stock pot.
Fill the stock pot with water. Add in your seasonings and salt then cover with lid.
Put your burner on high heat under your stock pot and let come to a boil and simmer for 30 to 45 minutes.
Add more water if needed. Turn your heat to low and let simmer for another hour.
Once finished, taste and add salt or seasoning to your preference.
Strain your broth from the scraps. If time allows, wait until your broth is warm, but not boiling hot to strain.
Use your broth for recipes, or keep in the fridge for 4-5 days to use later.
Pick your turkey scraps clean of any meat to use later.
Enjoy using this rich broth in your recipes!
