Tender manicotti shells are stuffed with a creamy ricotta mixture, nestled in a quick skillet meat sauce, and baked under melty mozzarella and Parmesan. A cozy, make-ahead-friendly pasta bake that feeds a crowd.
For no-boil shells, skip pre-cooking and add 1/2 cup extra liquid to the sauce; bake covered longer until tender. Drain ricotta if watery to avoid a thin filling. Assemble up to 24 hours ahead and refrigerate, adding 5–10 minutes to bake time if chilled. Freeze unbaked or baked (cooled) for up to 2 months; bake from frozen at 375°F covered, adding 15–20 minutes, then uncover to brown. Variations: add squeezed-dry spinach to filling, swap in sausage or turkey, use vodka sauce, or add sautéed mushrooms.
