What kind of cheese should be used for tostadas?

We recommend using white cheese as it is much easier to determine when the tostada shells are done cooking. If you use an orange cheese then it will not be as obvious when the cheese tostadas turn golden brown in color. 

Can you make tostadas with shredded cheese?

That being said, you can also make cheese tostadas with shredded cheese. All you have to do is organize a few piles of shredded cheese on the baking shredded and bake them until they melt together.

If you make cheese tostadas with shredded cheese, it is important that you use an even layer of cheese. Otherwise, the tostadas will burn on one side before the other side has cooked all the way through.
