Preheat oven to 350ºF.

Prepare a pot of boiling water while preparing the ricotta filling, then turn down to low heat to keep hot.

Mix the ricotta, mozzarella, Parmesan, egg, and parsley together. Set aside.

Place the lasagne sheets into the hot water for 2-3 minutes at a time, careful not to stick together. Using tongs to remove the lasagne sheets, run lasagne under cold water to prevent further cooking.

Prepare the rollups one at a time by placing a lasagne sheet on a flat surface. Spoon 2TB filling on to the left 1/4 of the sheet, spreading filling the width of the sheet. Proceed to completely roll up the lasagne with the filling, placing seam side down into a pan lined with non-stick foil.

Continue rolling all lasagne sheets with filling.

Once all roll-ups have been placed in the pan, spoon marinara sauce on top and sprinkle with mozzarella cheese and basil.

Bake 15 minutes in the oven, and allow to cool 5 minutes before serving.
