Step 2

Season beef with salt and pepper. Working with one slice at a time, spread 1 tbsp. mustard over surface. Lay 1 piece bacon, 1 pickle spear, and about 5 slices onion across one narrow end; roll into a tight package and secure with toothpicks. Melt 2 tbsp. butter in a 6-qt. saucepan over medium-high heat. Working in batches, cook beef rolls, turning as needed, until browned, 12–14 minutes. Transfer to a plate. Add remaining onion, the garlic, carrot, and celery to pan; cook until soft, 6–8 minutes. Add wine; cook until almost evaporated, 1–2 minutes. Stir in stock and bay leaf and return beef rolls to pan; boil. Reduce heat to medium-low; cook, slightly covered, until beef is tender, 1 hour.

Step 3

Transfer beef rolls to a platter; discard toothpicks. Strain stock into a bowl. Add remaining butter to pan; melt over medium-high. Add flour; cook 2 minutes. Whisk in stock and cook until thickened, 4–5 minutes; pour over beef rolls. Garnish with parsley; serve with potatoes and sauerkraut, if you like.
