For the buttered egg noodles: Bring a large pot of water to a boil. Add the egg noodles and cook according to the package instructions. Drain and set aside.

For the beef stroganoff: Heat 1 tablespoon olive oil in a skillet over medium-high heat. Season the meat with salt and pepper. Add half the meat to the pan and brown it quickly. Remove the first batch and cook the rest of the meat. Remove and set aside with the first batch.

Pour the slurry into the skillet and cook until the sauce thickens.
