In a large skillet over medium heat, cook the ground beef, breaking it up with a spoon until it's completely browned. Drain off any excess fat, then add the minced garlic and Italian seasoning.

Stir in the tomato sauce and sugar, then season with salt and pepper. Let it simmer for 3-5 minutes to let all those flavors come together nicely.

In a mixing bowl, combine the cream cheese and sour cream, mixing until it's completely smooth and no lumps remain.

Boil the egg noodles in salted water according to package directions until they're al dente. Drain them well - you don't want excess water making your casserole soggy.

Grease a 9x13-inch baking dish. Layer half the noodles on the bottom, spread half the cream mixture over them, then half the meat sauce. Repeat with remaining noodles, cream mixture, and meat sauce. Top with all that shredded cheddar.

Bake uncovered for 20-25 minutes until the casserole is bubbling around the edges and the cheese is melted and golden. Let it rest for 5 minutes before serving.
