Are cast iron pans safe for babies?
Yes. Cast iron doesn't shed plastic or PFAS. It adds some iron to food, which is usually a plus for babies.
What's actually in it
Cast iron is just iron. A seasoned pan is iron with a thin layer of polymerized oil on top. No plastic, no PFAS, no coatings. It adds a small amount of iron to food, which most babies need more of anyway. Iron-deficiency anemia is one of the most common nutritional problems in the first two years of life.
The downsides are weight and care. A cast iron pan rusts if left wet and takes a minute to heat up.
What the research says
A 2025 study in Int J Environ Health Res tested common cooking utensils and found cast iron leached iron into acidic foods but not the problem metals (lead, cadmium, nickel). A separate 2025 study in J Hazard Mater showed PTFE nonstick particles damage gut cells. Cast iron avoids that whole issue.
For baby purees, stir-fries, and eggs, cast iron is a solid pick. Use the "dab of oil" rule to keep food from sticking, and never cook highly acidic dishes like tomato sauce in raw (unseasoned) cast iron, which can pull out more iron than a baby needs.
