Ingredients
Method
- Heat oven to 375°F. Oil a 9x13-inch dish. Boil shells in a large pot 2 minutes less than package time; drain and cool separately on a tray until safe to handle.
- Squeeze thawed spinach in a clean towel until no liquid drips. Mix with ricotta, egg, 1/4 cup Parmesan, lemon zest, nutmeg, pepper, and salt.
- Mix marinara and water; spread 1 cup in dish. Fill each shell with about 2 tablespoons filling; arrange in one layer. Cover exposed pasta with remaining sauce. Top with mozzarella and remaining Parmesan.
- Cover with foil and bake 30 minutes. Uncover and bake 10–15 minutes, until sauce bubbles and the center reaches 165°F. Rest 10 minutes; scatter with basil if using.
Notes
Equipment: 9x13-inch baking dish, large skillet, large mixing bowl, instant-read thermometer.
Serving size: 1/6 of the recipe.
Refrigerate leftovers in shallow containers within 2 hours (1 hour above 90°F); use within 3–4 days. Reheat the center to 165°F.
Use plain chopped spinach, thawed and squeezed dry; prepared creamed spinach is too wet for this filling.
