Flank Steak With Mustardy Onions And Rosemary Recipe By Tasty

Steps:

• Mix all ingredients except steak in a 13x9x2 inch glass baking dish.
• Add steak and turn to coat.
• Cover and refrigerate at least two hours, turning occasionally.
• Preheat grill or broiler to medium high heat.
• Remove meat from marinade and discard marinade.
• Grill steak to desired doneness, about 4 minutes per side for medium rare.
• Transfer steak to work surface and let stand 5 minutes.
• Cut across grain into thin strips.
• Arrange on a platter and serve.

Steps:

• Pat the steaks dry with a paper towel. Season generously on both sides with the salt and black pepper.
• Add the olive oil and 1 tablespoon of butter to a nonstick or stainless steel pan over medium-high heat. Sear the steaks, one at a time, until a golden brown crust forms, about 5 minutes per side. If the pan gets too dry, add a bit more olive oil. Transfer the seared steaks to a cutting board to rest.
• Add the shallots, capers, and remaining ½ tablespoon of butter to the pan. Cook for 2-3 minutes, or until the capers crisp slightly.
• Deglaze the pan with the wine. Cook until reduced by half, about 30-60 seconds. Add the mustard and cream and adjust seasoning to taste.
• Slice the steak into ¼-inch (6 mm) pieces and transfer to serving plates. Pour the sauce over the steak and garnish with sliced chives. Serve with roasted potatoes and a side salad.
• Enjoy!

Steps:

• Combine all ingredients in small bowl.
