Creating Creamy Baked Crab Cannelloni can be straightforward if you follow these simple steps:

1. Preheat Oven: Begin by preheating your oven to 375°F (190°C).
2. Cook the Cannelloni: Boil a large pot of salted water. Add cannelloni pasta tubes and cook for half the time suggested on the package. Drain and set aside.
3. Prepare the Filling: In a mixing bowl, combine the crab meat, ricotta cheese, half of the mozzarella, Parmesan cheese, parsley, lemon juice, garlic, and season with salt and pepper. Mix until well incorporated.
4. Fill the Cannelloni: Using a piping bag or a spoon, carefully fill each cannelloni tube with the crab mixture. Place them in a baking dish lined with a bit of béchamel sauce.
5. Add Sauce: Pour the remaining béchamel sauce over the filled cannelloni. Drizzle a little olive oil on top and sprinkle the remaining mozzarella cheese.
6. Bake: Cover the dish with aluminum foil and bake in the preheated oven for 25 minutes. Remove the foil and bake for an additional 15 minutes, or until the cheese is golden and bubbly.
7. Serve: Let it cool for a few minutes before serving. Garnish with extra parsley if desired.

These steps will guide you in easily creating a show-stopping dish that will leave everyone wanting more of your creamy baked crab cannelloni.
