Strip the rotisserie chickens of any excess meat and crack the bones to expose some of the marrow. Be sure to save the skin for the chicken stock.
2 large rotisserie chicken carcasses
Some meat is perfectly fine and helps to flavor the stock.
Add the chicken carcasses to a large stockpot (or crockpot) along with all the other ingredients. Cover and allow to simmer gently over low heat for 12-14 hours (but at least 8 hours and no more than 20 hours). For a crockpot, set it to low and allow the stock to simmer for the same amount of time.
3½ liters water, ½ medium yellow onion, 10 sprigs thyme, 50 grams ginger, 6 large cloves garlic, 2 stalks scallions, ½ teaspoon salt
Once done, strain the stock from the bones. Allow the stock to cool before portioning it into airtight containers.
A chicken stock from rotisserie chicken tends not to render a lot of fat, but if desired, you can remove any fat rendered by skimming it off the top after a couple of hours in the refrigerator.
Refrigerate for 3-4 days or freeze for 4-6 months.
You can get creative and use any herbs or vegetables you like. I reach for my wilting herbs & veggies first.
I have left my stock on the stove overnight, but if you prefer not to, I suggest starting it first thing in the morning on a day you're home or using a crockpot!
A chicken stock from rotisserie chicken tends not to produce any of the white foam typically seen when making a stock from raw chicken or/bones. If you notice collections of white foam, it is an indication that your heat is too high. Skim the froth with a spoon and lower the heat so that the stock is very gently bubbling.
