Preheat the oven to 350℉. Line a sheet pan with parchment paper or aluminum foil.
In a skillet pan, over medium-high heat, add the ground beef, onion, and garlic. Cook and crumble the ground beef. Once the ground beef is no longer pink drain the excess fat and grease from the pan.
1 pound ground beef, 1 onion, 3 cloves garlic
Stir in the spaghetti sauce, salt, Italian seasoning, and pepper. Reduce the heat to LOW and allow it to simmer while you cook the spaghetti noodles and prepare the bread boat.
1 jar (24 oz) spaghetti sauce, 1 teaspoon kosher salt, ½ teaspoon Italian seasoning, ¼ teaspoon black pepper
Bring a large pot of salted water to a boil and cook the spaghetti noodles according to the package directions. When the pasta is done drain it in a colander but do not rinse it. Add the cooked spaghetti noodles into the ground beef mixture and stir to combine everything together. * Cook to al dente for a firmer pasta or a couple minutes longer for a softer pasta. 8 ounces spaghetti noodles
While the pasta is cooking prepare the garlic bread boat. Cut a large oval around the top of your bread, leaving at least 1/2-inch border around the edge. Remove the middle section of the bread so you end up with a boat. * Careful not to cut it too deep or wide or it might not hold up to the spaghetti. 1 loaf French bread
Mix together the softened butter, garlic powder, and dried parsley. Spread it all over the inside of the bread boat. Place the garlic bread boat onto the prepared sheet pan and cook until toasted, about 5-8 minutes.
1/2 cup salted butter, 1 teaspoon garlic powder, 1 teaspoon dried parsley flakes
Fill the toasted garlic bread boat with the prepared spaghetti from the skillet pan. Top it with the shredded mozzarella cheese. Bake for 10-15 minutes. 1 cup shredded mozzarella cheese
Sprinkle on the parmesan cheese, cut the spaghetti boat into large slices and enjoy!
