Recipe Notes

BAKED CHICKEN SPAGHETTI

You can serve the Chicken Spaghetti straight out of the skillet (which is what I usually do), or if you want to make it extra cheesy, then you can make Baked Chicken Spaghetti.  To make Baked Chicken Spaghetti:

  • Preheat oven to 350 degrees F.
  • Lightly grease a 9×13 baking dish.
  • Transfer combined spaghetti to prepared baking dish.
  • Evenly top spaghetti with 1 cup shredded sharp cheddar cheese.
  • Bake at 350 degrees F for 25 minutes or until cheese is melted.

Make Ahead CHICKEN Spaghetti

You have two different options when it comes to making in advance, you can either reheat the spaghetti in a skillet, or transfer to a 9×13 baking dish then bake:

1. ASSEMBLE AND REHEAT IN SKILLET 

  • Take care that your noodles are cooked al dente and are rinsed in cold water so they don’t keep cooking.
  • Assemble sauce and pasta according to recipe directions.
  • Transfer to an airtight container and refrigerate.
  • When ready to eat, heat individual servings in the microwave or desired amount gently on the stove with a splash of milk or heavy cream to thin.

2. ASSEMBLE THEN BAKE

  • Take care that your noodles are cooked al dente and are rinsed in cold water so they don’t keep cooking.
  • Assemble sauce and pasta according to recipe directions.
  • Transfer to a lightly greased 9×13 baking dish, cover with an additional 1 cup shredded cheddar cheese and tightly cover with foil.
  • Refrigerate Chicken Spaghetti for up to two days.
  • When ready to eat, bake (uncovered) for 35-45 minutes or until heated through.  

HOW TO FREEZE UNBAKED CHICKEN SPAGHETTI CASSEROLE (RECOMMENDED)

For best results and more al dente pasta, I recommend freezing Chicken Spaghetti directly from the skillet before its baked.  

  • Take care to cook pasta al dente.
  • Combine Chicken Spaghetti according to recipe directions in a skillet.
  • Transfer to a freezer safe, lightly greased baking dish and let cool completely.
  • Wrap casserole dish all the way around with 2 layers of plastic wrap.
  • Cover the plastic wrap with one layer of aluminum foil.
  • Label Chicken Spaghetti.
  • Freeze for up to 3 months.

HOW TO FREEZE BAKED CHICKEN SPAGHETTI

This scenario would be for when you have leftover chicken spaghetti that you’ve decided to bake.

  • Make sure chicken spaghetti is in a freezer safe baking container or transfer it to one.
  • Cover chicken spaghetti casserole with plastic wrap and place in the refrigerator to chill completely before freezing (this will prevent an unpleasant texture).
  • Cover casserole tightly with a second layer of plastic wrap all the way around the dish followed by one layer of aluminum foil.
  • Label Chicken Spaghetti.
  • Freeze for up to 3 months.

HOW TO REHEAT FROZEN CHICKEN SPAGHETTI

  • You can either let chicken spaghetti thaw overnight in the refrigerator and bake per recipe instructions, adding an additional 10 minutes baking time or bake from frozen.
  • Note: Do NOT bake chicken spaghetti directly from frozen if using a glass baking dish – it will likely crack! 

TO BAKE FROM FROZEN:

  • Remove plastic wrap from casserole and cover tightly with foil.
  • Bake covered at 350 degrees F for one hour.
  • Uncover and bake an addition 10-15 minutes or until hot in the center.
