Toast the Bread: Turn oven on to broil. Slice the French bread into thick one inch slices. Butter one side lightly. Place on a cookie sheet with buttered side up. Repeat with the remainder of slices. Very lightly sprinkle the bread with garlic salt. Broil until toasty on the edges. Watch carefully to prevent burning!
Prepare the Cream Cheese Layer: Turn oven down to 350 degrees. Spray a 9×13 metal or glass pan with cooking spray. Place bread (toasted side up) into your 9×13 pan. Fill it up leaving very few gaps; cut one slice into pieces if necessary to fill large gaps. In a medium bowl, combine the cream cheese, mayonnaise and Italian seasoning using an electric mixer until smooth (be sure to scrape down the sides of your bowl). Using a spatula, spread the mix over all the bread slices creating a sheet of the cream cheese mix.
Add the Meatballs: Cut the thawed meatballs in half sprinkling them all over the cream cheese mix. This ensures they cook evenly and distribute throughout the casserole.
Sauce It Up: Pour your can of spaghetti sauce evenly over the meatballs. Make sure every meatball is coated in that delicious sauce.
Cheese, Please!: Evenly sprinkle the shredded mozzarella over the spaghetti sauce. Don’t be shy – the more cheese, the better!
