Let cool for about 5 minutes once out of the oven. This helps everything set up before you dish it out.

Cover the pan tightly with foil then bake for half an hour. Pop off the foil and slide under the broiler for a few minutes, keeping an eye out until the top goes golden.

Sprinkle on the parmesan and mozzarella you saved. Pour every bit of remaining béchamel sauce over the pasta so it's all nicely covered.

Squeeze your ricotta mix into each pasta shell using the bag. Line up the filled shells tightly in the baking dish. First, scoop 180 ml of the béchamel onto the bottom of the dish.

Set your oven to 190°C or 375°F to preheat.

Take a medium mixing bowl and mix together the egg, ricotta, half the mozzarella, half the parmesan, basil, salt, pepper, lemon zest, and garlic. Make sure it’s smooth, then transfer to a big bag for easy piping and cut the corner.

Bring a big pot of salty water to a boil. Drop in your cannelloni shells and cook till just slightly firm, following whatever time the package suggests. Drain right away in cold water so they stop cooking and don’t break.

Slowly whisk the warm milk into the roux so no lumps form. Mix in the nutmeg, mustard, salt, and pepper. Let it all bubble for just a couple minutes, then toss in the parmesan and stir until it disappears. Set aside.

In another pan, melt the butter on medium then add the flour. Keep whisking for about three minutes. Don’t let it brown—just watch closely.

Set your milk, garlic, and thyme in a little pan and slowly warm it on low for 15 minutes. Don’t let it bubble. Pull out the garlic and thyme before using.
