Ingredients

Pasta

  • 8 ounces cavatappi pasta

Steak

  • 1 pound top sirloin steak, cut into 1-inch cubes
  • 1 teaspoon blackened seasoning
  • ¼ cup (½ stick / 57 g) unsalted butter

Salmon

  • 1 pound salmon, skin removed, cut into 1-inch bites
  • 1 teaspoon blackened seasoning
  • 1 tablespoon vegetable oil

Sauce

  • 1 small yellow onion, diced (about ½ cup)
  • 2 teaspoons garlic, minced
  • 2 cups (476 g) heavy whipping cream
  • 2 cups (200 g) parmesan cheese, freshly grated
  • 1 tablespoon blackened seasoning
  • ½ teaspoon kosher salt
  • ½ teaspoon black pepper
  • parsley, chopped for garnish

Instructions

Pasta

  • Bring a large pot of salted water to a boil over medium-high heat. Add pasta and cook al dente according to package directions (8-10 minutes).
  • Reserve 1 cup of pasta water; drain the rest. Set aside.

Steak

  • Season cubes of steak evenly with blackened seasoning.
  • In a large skillet on high heat, add butter. Once melted, place the steak pieces in the skillet. Cook for about 1-2 minutes per side, or until browned outside and pink inside. Transfer to a plate and tent to keep warm.

Salmon

  • Pat salmon dry with paper towels, and season evenly with blackened seasoning.
  • To the same skillet over medium-high heat, add oil. Once hot, add salmon pieces. Cook for about 2-3 minutes per side or until seared and golden brown and cooked through to an internal temperature of 145°F. Transfer to the plate with the steak and tent to keep warm.

Sauce

  • To the same skillet, add onions. Cook until softened, about 3-5 minutes. Add garlic and cook for 1 more minute.
  • Add heavy cream, ¼ to ½ cup of pasta water, parmesan cheese, blackened seasoning, salt, and pepper. Stir until the cheese melts and the sauce thickens slightly.
  • Add cooked pasta to the skillet and toss to coat. Add more pasta water as needed to reach the desired consistency.
  • Top the pasta with the cooked steak and salmon pieces.
  • Garnish with parsley. Serve immediately.
