It’s comfort food time! We’ve already had some super cold days and that calls for warm filling meals! That’s exactly what you are going to get with this recipe. Have a large family? This recipe is for you. Don’t have a large family? This recipe is still for you.


For those who don’t have a large family, this recipe is perfect for leftovers. What I like to do is alternate a meal like this between dinner and lunch for a few days and fill in with other meals in between.


That’s if you don’t mind repeat meals. One thing for sure, this casserole will provide you with a meal for at least a few days and save you a lot of time.

Spaghetti Mac

You will need: 

  • Ground beef
  • Prego spaghetti sauce
  • Uncooked spaghetti noodles
  • Sharp shredded cheese
  • Yellow onion
  • Gren bell pepper
  • Lawry’s seasoned salt
  • Lawry’s garlic salt
  • Onion powder
  • Garlic powder
  • Black pepper


This casserole is great with a side salad or any other veggie of your choice. A side of bread is even better!

We’re going to make this recipe just like you would make spaghetti, then place it in a casserole dish with cheese and bake it. We are using a pre-made sauce by Prego. They make the best spaghetti sauce!

Steps to make this recipe:

We are using large macaroni noodles. You want to use the large noodles vs. the small ones. I promise you that it makes a difference.


Cook them until they are al dente. You don’t want to overcook the noodles because they will continue to cook when we place the spaghetti mac in the oven. I cook mine for 7-10 minutes.


A good way to gauge whether or not they are ready is when you see them plump up. As soon as they plump, immediately transfer your noodles to a colander and rinse them with cold water to stop the cooking process.

To prepare your ground beef, place it in a large skillet and add plenty of seasoning. This recipe calls for onion and garlic powder, garlic and seasoned salt and black pepper.


We’re not going to use too much. Just a little bit of all of them. Also, we can’t forget the yellow onion and bell pepper.

Add your diced onion and bell pepper right into the pan with the meat so it can all cook at the same time. Once your meat is brown, drain any excess oil from the beef.


Then add in your spaghetti sauce and mix everything together. Allow your ingredients for this spaghetti mac to simmer for about five minutes.

Now it’s time to form our casserole!

Grab your pyrex dish and spread the noodles along the bottom of the pan. Then pour your beef mixture over your noodles throughout the plan. Add 1/2 c of cheese and fold it into the casserole.


Then evenly spread the remainder of your cheese over the top of the casserole. And then you’re ready to cover your dish with foil and place it in the oven.


Bake your casserole for 25 minutes or until the cheese is melted and it begins to bubble around the edges. And just like that dinner is ready!
