Preheat oven to 375°F. In a large oven-safe skillet or Dutch oven over medium-high heat, cook the ground beef, onion, and garlic until beef is browned, about 7 minutes. Drain fat.

Reduce heat to low. Stir in tomato soup, milk, salt, pepper, and oregano until smooth. Fold in uncooked egg noodles and 1 cup of the shredded cheddar.

If skillet isn’t oven-safe, transfer mixture to a greased 9x13-inch baking dish. Smooth top and sprinkle with remaining 1 cup cheese. Bake 20 to 25 minutes until bubbly and cheese is golden.

Let cool 5 minutes, then scoop and serve hot.
