Can I make the stuffed shell ricotta cheese mixture without the egg?

Yeah – it will be a bit more crumbly than sticky but otherwise should work fine.

Sure. Are you mixing in some shredded mozzarella?

I will simplify my answer. Yes

It won’t hold together as well, but it should taste fine.

Sure. Maybe put the shells in facing up. Are you using a sauce?

I just mix mozzarella and ricotta and spinach. It works fine. I don’t really eat eggs and make manicotti all the time.

They turned out just fine without the egg. I added a mixed shredded cheese blend and made some meat sauce. Thanks everyone!!
