I have used this method of cooking manicotti for years. The secret when using canned or bottled sauce is to add 1 cup of water to the sauce and heating it before covering manicotti. It works every time.
This is a great recipe! So much easier messy around with the uncooked noodles. Filling them was so much easier. I just snipped a small corner from a freezer bag and filled away! This was delicious also. I will definitely make this again and again!
No Boil Manicotti? What a great idea. NOT! The opening of unboiled pasta is too small for this to be a short cut. The pastry bag idea also did not work for me. Although perhaps that is because I used cottage cheese instead of ricotta cheese. I used two jars of expensive, gourmet sauce and still had to double the cooking time due to pasta not soft enough after only 40 minutes.
