Using preshredded cheese

It takes time to prepare a lasagna dish—from heating the noodles to browning the filling to putting it all together. It makes sense that home cooks would seek to find quick fixes, such as utilizing pre-grated cheese in a box. From a time-management perspective, this can seem like a nice idea, but it's not a fantastic choice.

Pre shredded cheese has a number of unfavorable additives, such as anti-clumping chemicals like potato starch (via Science Direct). These chemicals make the pre shredded cheese more difficult to melt while also preventing it from sticking together. That's not all, either. According to NPR, fillers like wood pulp are frequently added to shredded cheese. Roll up your sleeves and grate your own cheese unless you want a coating of wood pulp and preservatives in your lasagna.
