Caramelized Onions Steak

Rub 1/4 tsp (1 mL) each salt and pepper over both sides of steak. In large skillet, melt half of butter over high heat; brown steak on both sides, about 2 minutes per side. Transfer to plate.

Reduce heat to medium-low; add remaining butter to skillet. Stir in onions, garlic and rosemary; cover and cook, stirring often, for 10 min or until onions are very soft and caramelized. Sprinkle with flour; cook, stirring, for 1 min. Gradually stir in milk then soy sauce and mustard.

Increase heat to medium; simmer, stirring, for 5 min or until sauce is thickened. Return steak and accumulated juices to pan; spoon sauce over top. Simmer, turning steak once and stirring sauce, for about 5 min or until steak is desired doneness. Remove from heat. Transfer steak to cutting board; let rest for 5 min. Season sauce to taste with salt and pepper. Slice steak thinly across the grain and serve with sauce. Sprinkle with parsley.

Cooking Tip:
Let cooked meats rest before slicing to allow the juices to redistribute through the meat rather than running out onto the cutting board, leaving the meat dry.
