There is one thing I’ve realized as I’ve been combing through my grandmother’s recipe book – The woman absolutely loved casseroles.
One thing I’ve realized about myself since? I share that love of casseroles.
I mean, how can you not?!
You get my point. We <3 casseroles.
Why do casseroles (especially this spaghetti casserole) rock?
- Well. This casserole has bacon. Is that a good enough reason?
- It also has a whole green pepper and mushrooms mixed in. Also upticks on the awesome scale!
- You can throw it in a casserole dish, bake and serve. Have you ever dreamed feeding a crowd could be this easy?
- Casseroles = Cozy and Delicious. (My professional opinion)

Spaghetti has often been a go-to whenever we are entertaining. Now that this Baked Spaghetti Casserole has made its debut in our household, it’s 100% going to become a regular guest.
Reasons why I love this baked spaghetti casserole?
- I love that I can make the spaghetti and bake in the casserole dish and it’s ready to be stored as leftovers. Easy to reheat and my family can simply cut a square out of the pan and get their spaghetti on. No need to combine or do anything more. Excellent.
- It’s the definition of comfort food. Cheesy and packed with comforting Italian flavor.
- Bacon. Worth repeating and no more words are needed here.

While this might not be the actual recipe of what some call a Million Dollar Spaghetti Casserole I’ve got to say this is a Million Dollar Spaghetti Casserole to ME.

Lindsay,
Have you ever mad this ahead and put it in the freezer (after baking)? I am making up some meals for some new moms at our church and would like to make a few ahead!
Thanx!
Denise
I’m new to this and wasn’t sure about a few things. Drain the fat after cooking the meat? Cut the bacon into chunks? Salt and pepper or some other seasoning?
Thanks
Can this be frozen & then baked at a later time??
