Step 1: Season and Sear the Steak
Season the steak cubes with salt and pepper. Heat olive oil in a large skillet over medium-high heat. Add the steak bites in a single layer and sear for 2-3 minutes per side, or until browned and cooked to your desired doneness. Remove the steak and set aside.
Step 2: Make the Garlic Butter
In the same skillet, reduce the heat to medium. Add the butter and minced garlic. Cook for 1-2 minutes, stirring frequently, until the garlic is fragrant.
Step 3: Prepare the Parmesan Cream Sauce
Pour the heavy cream into the skillet and bring to a simmer. Stir in the Parmesan cheese, garlic powder, and onion powder. Cook for 2-3 minutes, or until the sauce thickens. Season with salt and pepper to taste.
Step 4: Combine and Serve
Return the steak bites to the skillet and toss to coat in the sauce. Garnish with fresh parsley and serve hot over mashed potatoes, rice, or pasta.
