Making Lasagna in the Crock Pot? YES. Do.
So... I'm not going to bother with a long detailed 'recipe' for lasagna because seriously... there are a thousand of them and yet you don't really even need a recipe. Use your own favorite recipe or just layer some pasta, your spaghetti sauce, some cheese mixture (mozzarella, ricotta or cottage cheese, maybe an egg in there... or even sour cream if your crew hates lasagna with ricotta or cottage cheese) and some meat if you want it, etc. The point is, just layer your pasta, sauce and cheese... but try doing it in a crock pot. Usually I use lasagna noodles and I only cook them for a few minutes just to get a bit of the starch out of them but sometimes I don't even do that. This time I had rotini on hand so I used that instead.
Layer... in a greased crock pot or slow cooker. Put on low for about 6 hours. If your slow cooker cooks "hot" (the newer ones cook hotter than the older versions) then adjust accordingly. The cheese on the edges can brown and burn if you have it on high too long or even low if it's 'hot'. This is a great idea for having a nice, filling meal on a summer day, without using your oven and heating up the house.
