• Step 1: Cover potatoes and garlic with salted water in large saucepan and bring to a boil over high heat. Reduce heat to low and cook uncovered until potatoes are tender, about 12 minutes. Drain; return to saucepan. Add 1/4 cup butter, milk and salt and pepper to taste; mash until smooth.

• Step 3: Heat remaining 1 tablespoon butter in same skillet over medium heat and cook onion, stirring frequently, until golden, about 5 minutes. Stir in 1/4 cup water, cover and cook, stirring occasionally, until tender, about 4 minutes. Stir in sauce and bring to a simmer. Reduce heat and simmer 2 minutes.
• Step 4: Cut steak into 4 pieces. Spoon sauce onto plates; top with steak and serve with mashed potatoes. Garnish, if desired, with chopped parsley.
