EFK Rouladen

Ingredients
6 thin slices beef top round or chuck, about 5–6 oz each
1 1/2 tsp kosher salt
1 tsp black pepper
1/3 cup German or Dijon mustard
6 slices bacon
1 medium yellow onion, thinly sliced
2 dill pickles, cut into 6 long spears total
2 tbsp neutral oil
1 carrot, diced
1 celery stalk, diced
2 garlic cloves, sliced
2 tbsp tomato paste
1/2 cup dry red wine or additional beef broth
3 cups low-sodium beef broth
1 bay leaf
2 tbsp unsalted butter
2 tbsp all-purpose flour
Chopped parsley
Directions
1. Pound beef slices to an even 1/8 inch if needed. Season lightly. Spread each with mustard, then top with one bacon strip, some sliced onion and a pickle spear. Roll tightly and secure with kitchen twine or toothpicks.
2. Heat oil in a Dutch oven and brown the rolls well on all sides; transfer to a plate.
3. Add carrot, celery, remaining onion and garlic and cook 6 minutes. Stir in tomato paste. Deglaze with wine or broth, scraping the pot. Add beef broth and bay leaf.
4. Return rouladen, cover and braise at a gentle simmer 1 3/4–2 hours until very tender. Transfer rolls to a platter and remove ties or picks.
5. Strain the braising liquid. Melt butter in the pot, whisk in flour for 2 minutes, then gradually whisk in about 2 1/2 cups strained liquid. Simmer to a silky gravy. Return rolls briefly to warm through and finish with parsley.
