First, pour spaghetti sauce into a bowl and add 1/3 cup of water. Then grease the inside of your crock-pot with cooking oil or spray. Brown ground beef in skillet, then add entire container of ricotta cheese to beef, stir in.
Start layering in crock-pot: sauce first, then beef-ricotta mixture, noodles (uncooked - you'll have to break them up and layer... they will cook in sauce), sauce and cheese. Keep layering until you've used all of your beef-ricotta mixture. Top with cheese last.
