The meaty, rich flavor of steak is versatile enough to serve as a protein topping for many pasta dishes. If you want to do pasta and steak right, use a ribeye steak.
Ribeye is among the softest cuts of steak, with great marbling, and it will give way to chewing just as easily as pasta. That same marbling also contributes a great, rich flavor.
This cut is easy to prepare and will probably be ready before the pasta is boiled. A one-inch ribeye only requires three to four minutes for a medium rare cook.
