I’ve made this for dinner twice now, and it came out perfectly both times. I imagine that you could put this together the night before and then put it in the crock pot/slow cooker in the morning, but I haven’t tried that.
I would estimate that this takes about thirty minutes of prep time. Follow the link to the actual recipe, and modify what you like. For example, I used about 1 1/2 pounds of ground beef. I used Italian seasoning instead of parsley to mix with the ricotta, and I added some shredded mozarella as well. I only used 3/4 of the 16oz. container of ricotta. So make it your own as I did.
The prep includes chopping half an onion, a garlic clove, sauteéing and then cooking the meat and sauce. Layer as directed, and cook in the crock pot for 4-5 hours.
I was surprised at how moist the whole thing was, even as a leftover the next day. It was so easy, and tasted amazing! We paired it with pull apart garlic knots, again with my modifications.
