Homemade Lasagna Sheets
If you want to pre-make the pasta, air-dry it overnight, dusting with more flour if it's still too wet. Once completely dry, it will become stiff. Store in a paper bag, and use within a couple of days.
If using a pasta machine, divide dough into 3 equal portions. Flatten 1 portion and pass through the thickest setting of the machine. Dust with flour, fold in half like a book, and repeat 3 to 4 times - always flouring, folding, and passing through the thickest setting - until dough is smooth in texture, even in size, and no longer sticky. Set the machine to a middle setting and pass each sheet through once more. Move to the next-to-last setting and pass through again. Cut 1 long strip in half. Pass the first half through the thinnest setting. Place this very long and thin sheet on a floured cloth. Repeat with remaining dough to make 6 long sheets. Trim sheets to fit your baking dish. Air-dry for 30 minutes, assemble, and bake.
