Crock Pot Vegetarian Lasagna

READY IN: 5hrs 30mins
Recipe by CgyVegan

This is an easy lasagna to make. It smells wonderful while cooking and tastes great. I adapted this recipe from a combination of others and came up with this vegetarian version. You can make this vegan easily by adding more of your favorite vegetables and using soy cheeses. Even the non vegetarians I made this for had seconds.

I have made this a dozen times and never the same way twice. Sometimes I have fresh spinach; other times I use frozen chopped(thawed in microwave and well drained). My husband loathes mushrooms so I ... um... chop them up finely. Shhhh. Once I even substituted BOCA for the mushrooms. I have even put in finely shredded carrots when I needed to use them up. I have also used jar sauce a few times when I had to throw it together and leave. This works great. Just pick up at step 4 and you're done in 5 minutes. I have a large oval crockpot but have never used a full 2 boxes of noodles. I don't really double the noodles; they just overlap a bit. (And still my crockpot will be full to the top!) I have, however, used more than the called for cheese because we like a bubbly, browned (yep, it browns in the crockpot?!), cheesy top on our lasagna. I like this recipe so much that I doubt seriously I'll go back to cooking dry lasagna in the oven! Thanks for posting it.
