      The Best Turkey Casserole



    • You can sub in frozen butternut squash as a time saver. Just cook according to the package's instructions and add in.
    • If you're really in a rush you can use a large can or cream of mushroom soup in place of the brown butter brandy sauce. 
    • This recipe calls for gouda but any number of cheeses will be great including cheddar, jack, or muenster
    • Alchohol in the brandy will cook off but you can omit it if desired.
    • This casserole keeps for up to three days in the refrigerator but you can freeze it for up to two months. Make sure to wrap well.
    • I love egg noodles in this dish but macaroni, gemelli and rotini work well too.
