Once cooked, cannelloni can be frozen. Thaw in the refrigerator before reheating. You may find that the sauce has been absorbed into the pasta. Pour over a little water. Cover with foil and heat in the oven. Alternatively, cover with cling film and heat in the microwave. Do not re-freeze once thawed.
