Season the steak bites with salt and pepper.
In a skillet, melt the butter over medium-high heat. Add the steak bites and cook until browned, about 3-4 minutes. Remove the steak from the skillet and set aside.
In the same skillet, add the minced garlic and sauté until fragrant, about 30 seconds. Pour in the beef broth, scraping the bottom of the skillet to release browned bits.
Stir in the heavy cream and grated Parmesan cheese. Let the sauce simmer until it thickens, about 3-4 minutes.
Return the steak bites to the skillet, coating them in the Parmesan cream sauce. Stir to combine.
Garnish with fresh parsley before serving. You can serve the steak bites over pasta, or enjoy them with crusty bread for a complete meal.
