Crockpot baked penne

(TY Melissa)

Spray crockpot with non-stick spray. Rinse penne noodles and lay enough in the bottom of the crockpot to kind of cover it, about 20-25 noodles?? Cover with spaghetti sauce, then mozzarella cheese. Repeat with noodles, sauce and cheese until ingredients are gone. I use 2 jars of sauce to make enough for the family and some leftovers. I don't measure anything else. When everything has been added, pour about 1 cup of water around the edge of the crockpot!! This keeps the noodles from sticking, burning to the edge, and getting too dry. I didn't do this the first time and some of the top noodles didn't get cooked. Cook on high for 4 hours. I've never done it on low, but I imagine it could be done on low for 8 hrs. Serve!
