Ingredients

  • 8 ounces penne pasta
  • 1 pound large raw shrimp, deveined and tails removed
  • 1 teaspoon blackened seasoning (for shrimp)
  • 1 tablespoon vegetable oil
  • 1 pound top sirloin steak, cut into 1-inch cubes
  • 1 teaspoon blackened seasoning (for steak)
  • ¼ cup (57 g) unsalted butter
  • 1 small yellow onion, diced (about ½ cup)
  • 2 teaspoons garlic, minced
  • 2 cups (476 g) heavy whipping cream
  • 2 cups (200 g) freshly grated parmesan cheese
  • 1 tablespoon blackened seasoning (for sauce)
  • ½ teaspoon kosher salt
  • ½ teaspoon black pepper
  • 2 to 4 tablespoons reserved pasta water (as needed)
  • Fresh parsley, chopped (for garnish)

Instructions

  1. Bring a large pot of salted water to a boil and cook penne al dente according to package instructions. Reserve 1 cup pasta water, then drain and set aside.
  2. Pat shrimp dry and season with 1 teaspoon blackened seasoning.
  3. Heat vegetable oil in a large skillet over medium heat. Cook shrimp 1–2 minutes per side until pink and opaque. Transfer to a plate and keep warm.
  4. Season cubed steak with 1 teaspoon blackened seasoning.
  5. Increase heat to high and add butter to the same skillet. Once melted, cook steak 1–2 minutes per side until browned and cooked to preferred doneness. Remove and set aside with shrimp.
  6. Reduce heat to medium. Add diced onion and cook 3–5 minutes until softened.
  7. Stir in garlic and cook 1 minute until fragrant.
  8. Add heavy cream and ¼ cup reserved pasta water.
  9. Stir in parmesan cheese, 1 tablespoon blackened seasoning, salt, and black pepper. Cook, stirring constantly, until cheese melts and sauce thickens.
  10. Add cooked pasta and toss to coat. Add additional pasta water as needed to reach desired consistency.
  11. Return shrimp and steak to the skillet and gently toss or place over pasta.
  12. Garnish with chopped parsley and serve immediately.

Notes

  • Use ribeye, tenderloin, or strip steak for a richer variation.
  • Fettuccine or cavatappi can replace penne.
  • Add mushrooms or spinach for extra flavor and color.
  • Reduce blackened seasoning for a milder dish.
  • Refrigerate leftovers up to 4 days; freezing is not recommended.
