Arrange beef slices flat on a clean surface and gently pound to an even thickness. Season both sides with salt and black pepper.
02 -
Spread approximately 1 tablespoon of Dijon mustard over each beef slice. Evenly distribute chopped onions and pickle slices, then carefully roll each slice tightly from one end. Secure the rolls with kitchen twine or toothpicks.

Heat vegetable oil in a large skillet over medium-high heat. Sear the beef rolls on all sides until well-browned, then transfer to a plate.

In the same skillet, whisk in flour and cook for 1 minute. Gradually add beef broth, stirring well and scraping up any browned bits from the bottom of the pan to form a smooth sauce.

Return the seared beef rolls to the skillet, cover, and reduce heat to low. Simmer gently for 90 to 120 minutes, or until the beef is tender.

Remove rouladen from the skillet and allow to rest briefly. Slice if desired, serve with pan sauce drizzled over the top, and garnish with chopped fresh parsley.
