Blackened Steak and Salmon Alfredo is tender cubes of blackened seasoned steak and salmon mixed in a creamy alfredo sauce with al dente cavatappi pasta. It may look fancy, but it is easy to prepare and perfect for any night of the week! My Blackened Steak and Shrimp Alfredo was so delicious and popular that I had to try it with salmon, too!

Ingredients & Substitutions

Pasta: I love cavatappi pasta for its corkscrew, tubular shape that holds the sauce well! However, you could use other kinds of tubular pasta like penne, rigatoni, or pasta you have on hand. Or, make homemade shaped pasta to use! When draining the pasta, reserve a cup of pasta water to add to the sauce.

Steak: I used top sirloin, a relatively tender meat cut. Ribeye, New York strip, filet mignon, or tenderloin would also work.

Salmon: Look for a pound of salmon. Remove the skin and pat it dry before cutting it into bite-sized pieces.

Blackened Seasoning: It’s all about the blackened seasoning in this recipe. It is used to season both the steak and salmon. Plus, it is also added to the alfredo sauce! It does add a little heat to the dish, so adjust the seasoning to your liking. For the most flavor, make homemade blackened seasoning!

Alfredo Sauce: Blackened seasoning adds a little bit of smoky and spicy flavor to the creamy alfredo sauce. You could leave it out of the sauce if the seasoned steak and salmon is enough of a kick for you.

Why Reserve Pasta Water?

Pasta water is important for the sauce in this recipe (and others like my Vodka Sauce and Champagne Shrimp Pasta). It is added to the sauce to thicken it. (I start with 1/4 cup, adding more to reach my desired consistency). In addition, the starch from the pasta water helps bind the sauce and pasta together which gives you a full-flavored taste in every bite!

What To Serve With Blackened Steak and Salmon Alfredo

Many side dishes will complement the richness of the dish. Here are a few options to try:

Can I Make The Alfredo Sauce Ahead Of Time?

Sure, you can get the Alfredo sauce made in advance so it’s ready to heat up when you are ready to put the dish together. After you have made the alfredo, let it cool to room temperature. Then, store the sauce in an airtight container in the refrigerator for up to 3-4 days. When ready to use the sauce, reheat it slowly on the stovetop as you prepare the pasta, steak, and salmon.

Salmon

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

  • 2 cups (200 g) parmesan cheese, freshly grated
  • 1 tablespoon blackened seasoning
  • ½ teaspoon kosher salt

Instructions

Pasta

Steak

  • Season cubes of steak evenly with blackened seasoning.

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.
