Deliberately neutral homemade chicken stock made from roasted Costco rotisserie-chicken carcasses and bones with mirepoix, herbs, and a small amount of tomato paste; frozen in measured 2-cup and 4-cup packages.
Prepare & package
After breaking down the Costco rotisserie chickens, roast the carcasses and bones. Cook them on the stovetop with mirepoix, herbs, and a small amount of tomato paste over three days. Filter the finished stock three times, cool safely, measure into 2-cup or 4-cup portions, seal, and freeze.
Store & thaw
Keep the measured packages frozen. Thaw in the refrigerator or transfer to a suitable pan for controlled reheating.
Cook or reheat
Use without dilution. Add directly to a cooking dish when appropriate, or reheat until fully hot.
Finish & serve
The stock is deliberately neutral. Reduce, salt, and season according to the final dish rather than correcting the entire batch before freezing.
