Ingredients
Method
- Heat oven to 375°F; oil a 9x13-inch baking dish. Boil shells in a large pot 2 minutes less than package time; drain and separate on a tray until cool enough to handle.
- Squeeze thawed spinach firmly in a clean towel until no liquid drips. Mix with ricotta, egg, 1/4 cup Parmesan, lemon zest, nutmeg, pepper and salt.
- Mix marinara with water; spread 1 cup in dish. Fill each shell with about 2 tablespoons filling; arrange in one layer. Cover all exposed pasta with remaining sauce; top with mozzarella and remaining Parmesan.
- Cover with foil; bake 30 minutes. Uncover; bake 10–15 minutes, until sauce bubbles and center reaches 165°F. Rest 10 minutes; add basil if using.
Notes
Equipment: 9x13-inch baking dish, large skillet, large mixing bowl, instant-read thermometer.
Serving size: 1/6 of the recipe.
To freeze unbaked, use cold filling and cooled shells, assemble in a freezer-safe metal pan and cover airtight. Freeze for up to 2 months. Thaw fully in the refrigerator, usually 24–36 hours. Bake covered at 375°F for 40–50 minutes, then uncovered for 10–15 minutes, until the center reaches 165°F.
Refrigerate leftovers in shallow containers within 2 hours (1 hour above 90°F); use within 3–4 days. Reheat the center to 165°F.
