Recipe Notes

Sharon’s expert tips:

  • This casserole freezes beautifully. To make ahead, before baking, simply cover tightly and freeze for up to 2 months. Thaw overnight in the refrigerator and bake as directed.
  • Classic turkey tetrazzini contains English peas. I didn’t include them, but please add them in if you like them.
  • Cooked chicken makes a great substitute for turkey.
