Rinderrouladen

Preparation of the Filling In a skillet, cook the bacon until crispy. Remove the bacon and set it aside. Add butter to the skillet and sauté the diced onion and mushrooms until tender. Transfer the onion-mushroom mixture to a bowl and mix in the bread crumbs. Crumble the crispy bacon and add it to the mixture. Season with salt and pepper to taste.

Assembling the Rouladen Lay out the beef slices and season each with salt, pepper, and paprika. Spread 1 tablespoon of mustard on each slice. Place a slice of bacon, onion, and dill pickle on top of each beef slice. Place a portion of the filling on top of the bacon, then roll up the beef slices and secure them with toothpicks.

Browning the Rouladen In a large skillet, brown the rouladen on all sides over medium-high heat. This will give the rouladen a nice color and add flavor to the dish.

Slow-Cooking the Rouladen Transfer the browned rouladen to a slow cooker and cook on low for 4-5 hours, or until the beef is tender and the flavors have melded together.
