Gather all ingredients.

Sauté ground beef in a large skillet over medium heat until browned and crumbly.

Fill a large pot with lightly salted water and bring to a rapid boil. Cook egg noodles at a boil until tender yet firm to the bite, then drain and set aside.

Drain and discard any fat from the cooked beef. Stir condensed soup and garlic powder into the beef. Simmer for 10 minutes, stirring occasionally.

Remove beef from the heat. Add egg noodles and stir to combine. Stir in sour cream and season with salt and pepper.
