How To Make It

Heres how to make this incredible pasta dish. You can find the full ingredients list and instructions on the recipe card below.

Preheat the oven to 350°

First, add the ground beef, chopped onion, garlic and bell pepper to a large skillet. Brown the ground beef and vegetables together, breaking the beef into small pieces as cooks. Drain any excess fat and season with salt, pepper, garlic powder and Italian seasoning. Stir in the tomato sauce and simmer for about 5-10 minutes.

Now, toss the cooked spaghetti into the Alfredo sauce and add it to a greased 9” x 13” baking dish. Spread it out so that it's flat and even and spoon the tomato sauce and beef mixture to the top.

NOTE: The pasta may look like it has just a little too much Alfredo sauce on it. That's actually exactly what you want to make sure the pasta doest dry out in the oven.

Now, top the beef mixture with Parmesan cheese and shredded mozzarella cheese. Finally, place it into the center rack of the oven, uncovered, for about 20 minutes or until the cheese is melted and the sides are hot and bubbly. Let rest for 5-10 minutes and enjoy!

PRO TIP: Let the casserole rest to firm up and settle. It will make it must easier to serve and eat.

Do I Have To Use Jarred Tomato And Alfredo Sauce?

Absolutely not! Feel free to make your own or use my homemade recipes for Tomato and Alfredo sauces. I just like to use jarred sauces here because it makes my life much easier. If you do go the jarred sauce route- I recommend Raoes.

What Can I Serve This With?

Casseroles like this one are great because they don't really need to be served with much else. A simple side salad, some homemade garlic bread or roasted vegetable like Broccoli would be great choices.
