Here's Why You Shouldn't Leave a Ladle in the Pan While Cooking

A ladle placed in a casserole dish can fall at any time. If it falls into a cooking utensil, it can cause hot liquid to splash, increasing the risk of burns and damage to the cooktop.
Even just lifting it may involve touching a hot surface, which carries the risk of painful burns.

Leaving
a ladle in a Dutch oven while cooking often means more stains and splatters on your kitchen counter and stove.

If the ladle is too hot, food residue may stick and be difficult to remove. Removing it after each use will help prevent this from happening.
