A popping sound is normal for foods with high fat or water content, like steak or tomato sauces, and is also normal for other types of food, like potatoes or popcorn. Similarly, any food residue left in a dirty microwave may also make popping sounds.
Popping sounds are usually caused by the food item being cooked in the microwave. Food items with a higher fat content will pop and sizzle as they cook. Covering the container will reduce this. Noises can also be heard when cooking foods with tight membranes such as potatoes.
Why is my Samsung microwave making a crackling noise?
