Cut the sirloin or ribeye steak into bite-sized cubes and season with salt and pepper.

Heat olive oil in a large skillet over medium-high heat and sear steak cubes for 2-3 minutes on each side until browned.

In the same skillet, add unsalted butter and minced garlic, sauté for 30 seconds, then add steak back into the skillet.

In a separate saucepan, melt butter, add garlic, then heavy cream and whisk in Parmesan until smooth.

Serve the steak bites with the Parmesan cream sauce draped over and garnish with parsley.
