Begin by boiling water in a large pot, once the water is boiling, salt it generously and add the shells. Give it a soft stir, but don’t disturb the shells too much. Timing is critical here, because if you over cook the shells, you will have a mushy mess.

Follow the package directions and cut the highest time by half and start tasting for doneness at that point. Example, the package of shells I used said 10-13 minutes. I started tasting at 7 minutes. Had I cooked them for even 10 minutes, they would have been too soft. I found 9 minutes was perfect.

When they are cooked very al dente, pour them into a colander and rinse them well with cold water. Separate them with your fingers and continue to rinse until they are cool. As they are rinsed, they will not stick together.

Beat together your two egg yolks and your egg and them fold in the ricotta, Parmesan and mozzarella. Add in salt, pepper, parsley and nutmeg. Put this mixture into a gallon freezer bag and twirl the bag to make a piping bag, then cut a 1/2 inch corner off the end to fill the shells.

Put about 1 1/2 cups of you marinara on the bottom of your baking dish and then take each shell and pipe in the ricotta mixture. Squeeze the shells slightly and lay them next to each other in the dish.

When all the shells have been filled, or you are out of room, sprinkle on the oregano, add the rest of the marinara and add more Parmesan and or mozzarella cheese. Cover tightly with foil and into a 375F oven for 35-40 minutes. Cook until it is bubbling. Remove from the oven, uncover and let it rest for 5 minutes and serve.
