Cook, whisking often, until sauce begins to simmer, 3 to 5 minutes. Sauce will not be very thick, but will thicken when baked with the shells.

Recipe View Remove sauce from heat, and transfer 3/4 of it into a 9x12-inch baking dish. Reserve the rest for the top.

Recipe View Meanwhile, bring a large pot of lightly salted water to a boil. Cook pasta shell in the boiling water, stirring occasionally, until about 75% tender, about 9 minutes (full cooking time would be 12 minutes). Drain and cover with just enough cold water to cover to prevent shells from drying out.
