Pat the steak dry and season generously with salt and pepper.

Heat olive oil in a large skillet over medium-high heat and sear the steak cubes for 2-3 minutes per side.

In the same skillet, melt unsalted butter and stir in minced garlic, sautéing for 30 seconds.

Return seared steak cubes to the skillet, coating them in the garlic butter, and cook for another minute.

In a separate saucepan, melt 1 tablespoon of butter, add 2 minced garlic cloves, and then stir in heavy cream and Parmesan cheese until smooth.

Drizzle cream sauce over the steak bites or serve it on the side. Garnish with parsley and red pepper flakes.
