How to Make Baked Spaghetti
- Step 1 – Preheat the oven to 350 degrees F. Spray the baking dish with cooking spray to easily serve.

Frequently Asked Questions
This is a great casserole to prepare the day before. Prepare the baked spaghetti as the recipe indicates, then cover and store in the refrigerator. You may need to adjust cooking time to cook a few minutes to ensure that the center gets heated through.
Store leftover baked spaghetti in the refrigerator in an airtight container for up to 5 days.
You can freeze your leftovers or freeze unbaked spaghetti if you like to double the recipe. If you are planning to freeze the baked spaghetti I like to prepare in a disposable pan covered with plastic wrap and aluminum foil. Freeze for up to 3 months. If you are freezing it baked, just place in a freezer safe storage container and thaw in the fridge when ready to reheat.
If I have a small portion to reheat, I like to reheat in the microwave. But if you are reheating a larger portion, place in a casserole dish and reheat in the oven at 350 degrees for about 10 minutes.
