You may notice a white, gooey substance coming out of chicken breasts while cooking. Although it looks unappealing, it’s completely normal and safe. The “white goo” is just water and proteins pushed out of the meat as the chicken heats up. Lean cuts like boneless, skinless breasts release more of it, especially when cooked at high temperatures or when the chicken wasn’t fully thawed.
This residue isn’t a sign of spoilage or undercooking. As long as the raw chicken doesn’t smell bad, feel slimy, or look gray, it’s safe. To reduce the white buildup, cook at lower temperatures, brine the chicken, sear before baking, or let it reach room temperature before cooking. It might look odd, but it’s harmless—and your chicken is still perfectly fine to eat.
