ABOUT THIS RECIPECreamy filling, fresh tomato sauce
This Italian baked pasta is all about the interplay of three layers: pasta tubes, a soft filling and sauce that cooks everything through in the oven. Ricotta makes the spinach mild and creamy; Parmesan adds saltiness and depth, while a pinch of nutmeg rounds out the filling. The tomato sauce keeps the dish fresh and slightly tangy. A thin layer of béchamel on top protects the pasta from drying out and gives the surface a golden-brown finish.
Fresh spinach wilts quickly in the pan, but holds a lot of water after cooking. So let it cool first, then squeeze it firmly before chopping it finely. Spinach that is too wet makes the ricotta filling runny and can leave extra liquid in the baking dish. Frozen spinach works too: let it thaw completely and squeeze out the moisture as well. Fresh spinach is often widely available in spring and autumn, but frozen spinach is a practical choice for this dish outside the season.
The filling should be creamy, but firm enough to stay inside the tubes. A piping bag or sturdy freezer bag with a small corner cut off makes filling them easy; you can also use a teaspoon, though it takes a little longer. Dry cannelloni tubes cook in the oven by absorbing moisture from the sauce. So make sure both the bottom and the top are well covered, and cover the dish for the first part of the baking time. The extra splash of water added to the passata helps the pasta soften evenly.
The béchamel doesn’t need to form a thick blanket here: a thin layer is enough for a soft topping without overpowering the tomato sauce. Gradually stir the milk into the roux to prevent lumps. If the sauce has become too thick, whisk in a small splash of milk. For a more pronounced cheese flavor, add a little extra Parmesan, but keep its salty taste in mind when seasoning.
Serve the cannelloni straight from the baking dish with a green salad or simple vegetables, so there’s something fresh alongside the creamy pasta. Cool leftovers quickly, cover and refrigerate within two hours, and eat them within three days. Reheat portions thoroughly in an oven at 180 °C, covered with foil so the top doesn’t get too dark; add a spoonful of water to the dish if needed.
