Your family will love this baked “millionaire” spaghetti casserole! Follow the recipe directions below to make TWO 9×13 casseroles (bake one for now and one for later). Or choose to walk on the freezer cooking wild side with me and make FOUR or more 9×13 baked millionaire spaghetti casseroles!


TWO 9×13 Pans

  • 2 pounds spaghetti
  • 2 pounds ground beef
  • 1 large onion
  • 2 cloves garlic, minced
  • 2 (24 ounce) jars marinara sauce
  • 1 (8 ounce) package cream cheese, softened
  • 1 (24 ounce) container cottage cheese
  • 6 cups shredded mozzarella cheese

FOUR 9×13 Pans

  • 4 pounds spaghetti
  • 4 pounds ground beef
  • 2 large onion
  • 4 cloves garlic, minced
  • 4 (24 ounce) jars marinara sauce
  • 2 (8 ounce) package cream cheese, softened
  • 1 (24 ounce) container cottage cheese
  • 12 cups shredded mozzarella cheese


  • Preheat oven to 350 degrees. Prepare two or four 9×13 casserole dishes with nonstick cooking spray.

  • In a large skillet over medium high heat, brown the ground beef with the onion until the meat is crumbled and no longer pink. Drain well and return to pan. Stir in one jar of marinara sauce with enough water to rinse the jar.

  • Meanwhile, cook the spaghetti noodles according to package directions. Drain and stir in the remaining jar of marinara sauce.

  • In a large bowl, beat together the cream cheese, cottage cheese, and 1 cup shredded mozzarella cheese.

  • In the bottom of the casserole dishes, layer spaghetti, cream cheese mixture, and meatsauce. Repeat at least once.

  • Top the casserole with remaining cheese.

  • Cover and bake for 30 minutes. Remove the cover and continue baking for another 15 minutes or until the cheese has melted and the edges bubble. (see alternative step 7 below for freezer meal directions)



  • To make your extra casseroles into freezer meals still follow the listed steps above 1-6.
  • For step 7 do not bake your casserole. Instead, wrap each of your extra freezer meal casseroles with two layers of foil (lable and date your meals) followed by two layers of plastic wrap.
  • Place freezer meal casseroles in the freezer for 3+ months
  • When you want to serve bake millionaire spaghetti casserole for dinner, just set it out from the freezer into the refrigerator the day before.
  • On cooking day remove the plastic wrap and one layer of foil. Tent the remaining layer of foil for baking. Bake your casserole at 350 for 30 minutes. Depending on your casserole temperature and level of defrostedness you may have to add additional cooking time to your bake in 15 minute increments. Lastly, remove the tented foil cover and continue baking for 15 minutes or until the cheese is hot and bubbly.
  • Always bake your cassoroles to at least an internal tempture of 165 degrees.
