Step 1

Cook spaghetti in salted water, according to package directions. Drain.

Step 2

Combine shredded mozzarella and cheddar; set aside.

Step 3

Meanwhile, season ground beef with salt and pepper. Brown ground beef in a large skillet; drain. Add sauce to ground beef and bring to a simmer to heat through.

Step 4

Combine cooked spaghetti and sauce; toss to coat. Stir in 3 cups shredded cheese.

Step 5

Spoon into a greased 9x13" baking dish. Top evenly with remaining 1 cup shredded cheese.

Step 6

Bake at 350℉ for 30 minutes until heated through and cheese is melty.

Step 7

Use up to 1 & 1/2 lbs. of ground beef if you'd like your baked spaghetti extra-meaty.

Step 8

We use Prego or Ragu brand marinara sauce. Any meatless/marinara sauce works great, so use your favorite.

Step 9

It never hurts to add even more cheese!  For the best and meltiest result, shred the cheeses yourself from a block rather than using packaged pre-shredded cheese.

Step 10

This recipe makes a pretty big batch of baked spaghetti that's certainly enough for leftovers for our family.  The recipe can easily be halved to make a smaller pan, if you'd like.
