  • 2 tablespoons chopped fresh parsley

Equipment

  • Large pot
  • Large skillet
  • Plate

Method
 

  1. Bring a large pot of salted water to a boil. Add pasta shells and cook until just tender, about 9 to 10 minutes. Reserve 1/2 cup pasta water, then drain.
  2. Pat steak cubes dry and season with salt, black pepper, and paprika.
  3. Heat olive oil and 2 tablespoons butter in a large skillet over medium high heat until hot.
  4. Add steak in a single layer and sear for 2 to 3 minutes per side until browned and cooked to your preferred doneness. Add garlic during the final minute and stir. Transfer steak to a plate and keep warm.
  5. In the same skillet, melt 3 tablespoons butter over medium heat. Add garlic and cook for 1 minute until fragrant.
  6. Pour in heavy cream, add Italian seasoning, salt, and black pepper, and simmer for 4 to 5 minutes until slightly thickened.
  7. Stir in Parmesan cheese a little at a time until the sauce is smooth and creamy.
  8. Add cooked pasta shells and toss to coat. Use a splash of reserved pasta water to loosen the sauce if needed.
  9. Return steak bites to the skillet and gently fold together. Cook for 1 to 2 minutes until heated through.
  10. Sprinkle with chopped parsley and serve immediately.

Notes

Cook steak to an internal temperature of 145°F and allow it to rest briefly before serving for safe and juicy results.
