Creating a Creamy Steak and Pasta Dinner can be a straightforward process if you follow these steps carefully:

1. Cook the Pasta: Bring a large pot of salted water to boil. Add the pasta and cook according to package instructions until al dente. Drain and set aside.

2. Prepare the Steak: Season both sides of the steak with salt and pepper. This enhances the flavor of the meat.

3. Sear the Steak: In a large skillet, heat the olive oil over medium-high heat. Add the steak and sear for about 5-7 minutes on each side or until desired doneness. Remove from pan and let it rest.

4. Sauté Aromatics: In the same skillet, add the chopped onion and minced garlic. Sauté for 2-3 minutes until fragrant and translucent.

5. Make the Sauce: Pour in the beef broth and heavy cream. Stir to combine, bringing the mixture to a gentle simmer.

6. Season the Sauce: Add the Italian seasoning, salt, and pepper to taste. Let the sauce simmer for about 5 minutes, allowing it to thicken slightly.

7. Combine Ingredients: Slice the rested steak into strips and add it back to the skillet, followed by the drained pasta. Toss well to coat everything in the creamy sauce.

8. Add Cheese: Stir in the grated Parmesan cheese until melted and fully incorporated into the sauce.

9. Finish Cooking: Allow everything to cook together for another minute or two, ensuring the pasta is heated through.

10. Serve Warm: Remove from heat and sprinkle with fresh parsley before serving.
