This fits 2 of the Costco lasagnas. I bought one for my mom and myself and she had a large amount of family over and we don't cook/bake in the plastic/cardboard containers the items come in. She was super nervous to figure out how to bake 3 lasagnas in the oven and after I gave this to her for an early birthday, she was pleased that 2 of those narrow sheets fit perfectly and only needed 1 more vessel for the 3rd lasagna.
I used this to make 5.5# of beef roast. They were in 2 cuts and it turned out so well especially being able to add onions and homemade beef broth. This is a very tall sided roasting pan. Would definitely buy again.
