HOW LONG TO COOK TURKEY CASSEROLE WITH PASTA

Your casserole will need to bake at 350° F for about 30 minutes, or until heated through and bubbly.

CAN YOU FREEZE TURKEY CASSEROLE WITH PASTA?

Yes, you can freeze this cheesy turkey tetrazzini. Just be sure to store it in an airtight container so it doesn’t get freezer burn.

When you take it out of the freezer, you can either allow time for it to thaw or reheat as is. Of course, oven times will vary, depending on whether it's thawed or frozen.

Reheat individual servings, or place the entire baking dish, covered with aluminum foil, in the oven at 350° F until heated through.

ALTERNATIVE INGREDIENT OPTIONS:

There are a few ways you can change this recipe up and make it slightly different…

  • Don't have turkey? Use chicken instead; rotisserie chicken would taste great. Just shred it up and add as you would the turkey.
  • If you're like me and don't care for mushrooms, leave them out. I usually just put up with them because my family likes them, and I can hardly tell they're there if I dice instead of slice.
  • Use spaghetti noodles or fettuccine noodles instead of egg noodles.
  • Use gluten-free pasta and gluten-free flour to make this casserole gluten-free. Of course, check the labels on all of your other ingredients to ensure that everything is gluten-free if going this route.
  • Add a smoked cheese for a smoky flavor to your turkey casserole.
  • Add a vegetable to the casserole. Peas are delicious in a cheesy casserole.
