Total Time20 mins
Servings: 3


  • 3 6-ounce sirloin steaks
  • 4 tablespoons butter salted
  • 1 large onion
  • ¾ cup heavy cream
  • 3 tablespoons Worcestershire sauce
  • cup crumbled blue cheese (plus more for topping)
  • salt and pepper to taste


  • Remove the steaks from the refrigerator about 15-30 minutes before cooking. The closer the steaks are to room temp, the more evenly they will cook. Slice the onion into stips. Set aside. Preheat the grill to high heat.
  • Use 2 tablespoons of butter to rub over the 3 steaks (both sides). Sprinkle some ground pepper over both sides. Place steaks onto preheated grill and cook for 3-4 minutes per side or until desired temperature is reached. I like my steaks medium-rare so I cook to 130 degrees. Remove the steaks from the grill and let them sit UNTOUCHED while make the onion sauce.
  • Add remaining butter to a large pan over medium-high heat. Once melted, add sliced onions. Cook until they begin to char a little, about 8-10 minutes. Once cooked, reduce heat to medium-low.
  • Add cream and Worcestershire sauce to the onions and stir together. Bring to a simmer and let the sauce thicken up a bit, about 2-3 minutes. Make sure to stir regularly so the sauce doesn't burn. Remove from heat once thicken.
  • Finish off the sauce with blue cheese crumbles, Stir until the crumbles have completely melted. Give the sauce a taste and add salt & pepper, as needed. Slice the sirloin and serve with the sauce over the top.
