“Dry spinach and cool filling prevent watery rolls.”
Individual portions rather than a slab, which means you can pull out two on a Tuesday and leave the rest frozen. They assemble in about half an hour and go into the freezer raw, so the work happens once and the payoff arrives on four separate evenings.
Water is what turns this into soup, and it comes from two places. Thawed greens hold far more than looks possible, so squeeze in handfuls until nothing more runs out. The cheese mixture also has to be thick enough to hold a ridge from the spoon; loose filling seeps out of the spiral while it bakes.
🍝 The promise: Twelve filled spirals you can bake now or freeze in the dish: about thirty-five minutes of assembly and forty-five in the oven.


Twelve rolls is exactly what a 9-by-13-inch dish takes shoulder to shoulder, which is why the filling is measured at a scant ⅓ cup (80 g) per noodle.
The dish can go straight into the freezer once the sauce and cheese are on; everything up to that point is assembly rather than cooking.
Squeeze the thawed spinach in handfuls until no more green water runs out, and lay the cooked lasagna noodles flat on a towel so they cool without sticking to each other.

Stir the cooked chicken, spinach, ricotta, half the mozzarella, and the salt together until the filling is thick enough to hold a ridge from the spoon. Season to taste before it goes near a noodle.

Spread a scant ⅓ cup (80 g) of filling down the length of each noodle, stopping an inch short of the far end so nothing squeezes out when you roll.

Roll each noodle up from the short end with steady, gentle pressure and set it seam-side down in a baking dish. Packed snugly, twelve rolls should sit shoulder to shoulder without being crushed.

Ladle the marinara around and over the rolls until they are half-submerged, then scatter the remaining mozzarella on top and cover the dish tightly with foil. Freeze at this point if you are making it ahead.

Bake at 375°F (190°C) for 30 minutes covered, then pull the foil and give it 15 minutes more, until the cheese browns in patches and the center registers 165°F (74°C).

Sauce bubbles up between the spirals, the cheese is browned and set, and each roll holds its shape on the spatula. If the cheese darkens before the center of a roll reaches 165°F (74°C), lay the foil back over and keep baking rather than raising the oven.
Grate a little nutmeg and the zest of half a lemon into the ricotta before the chicken goes in. Both cut through a filling that is otherwise all dairy and greens.
