I wanted to try this as a lasagna. Do you think it will set up or should I just do it as a casserole? I plan to use a 9x13 pan.
Give it a go - I would think you’d want to get the sauce at a decent thick consistency- something on the lines of the look of a pasta sauce.
Play with it - maybe add cream for some of the milk - or cook down to thicken more - add more Parmesan, etc. If it’s too loose I don’t know how well it would set-up.....
I bet it would make a nice lasagna.
I’m getting to like white lasagnas more than the reds nowadays....I’m not a big tomato person anyway.
