How to make Seafood Cannelloni
Start by preheating your oven to 375F.

- Make the filling by combining in a mixing bowl, the ricotta, lemon zest, pesto, garlic, drained crab meat, parmesan, salt, and Old Bay seasoning.

- Spread evenly, one of the bottles of alfredo sauce, into the bottom of a 9"x13" baking dish. Set aside.

- Place the filling into a piping bag in order to fill the cannellonis. You can also use a plastic freezer bag by making a small cut in one of the corners.

- Place the filled cannellonis, in 2 rows of 8, over the alfredo sauce. Sprinkle the shrimp over the cannellonis. Pour the second bottle of alfredo sauce over the top and spread evenly.

5. Sprinkle the grated mozzarella cheese evenly on top. Cover the baking dish with aluminum foil.

6. Bake in the preheated oven for 30 minutes. Remove the foil, and return to the oven for 10-15 minutes or until golden brown. Let it rest out of the oven for 5-10 minutes before serving.
Storage
Store leftover Seafood Cannelloni in an airtight container in the refrigerator for up to 3 days. Keep the portions covered tightly to prevent the pasta from drying out and the seafood from spoiling quickly. Freeze baked cannelloni in a freezer-safe container for up to 2 months, layering parchment paper between pieces if stacking. Reheat in the oven at 350°F (175°C) until warmed through, adding a splash of sauce or broth to keep it moist, or microwave individual portions for a quicker option.
