Ingredients:
- 1 lb sirloin or ribeye steak
- 1 tablespoon olive oil
- 2 teaspoons Cajun seasoning (divided)
- 2 tablespoons unsalted butter
- 2 garlic cloves, minced
- 1½ cups heavy cream
- 1 cup grated Parmesan cheese
- ½ teaspoon smoked paprika
- 12 oz fettuccine pasta
- Salt to taste
- Freshly ground black pepper to taste
- Fresh parsley, chopped, for garnish
Prepare the Steak
Season and Sear
The foundation of our delicious Cajun Steak Alfredo is, of course, the steak. For the best flavor and tenderness, I highly recommend using either sirloin or ribeye. Both offer a good balance of marbling and richness. Pat your steak completely dry with paper towels. This is a crucial step as moisture on the surface will steam the steak rather than sear it, preventing that beautiful, flavorful crust. In a small bowl, combine 1 teaspoon of the Cajun seasoning with a generous pinch of salt and freshly ground black pepper. Rub this mixture all over the steak, ensuring it’s evenly coated on all sides.
Heat the olive oil in a large, heavy-bottomed skillet (cast iron works wonderfully here) over medium-high heat. You want the oil to be shimmering but not smoking. Carefully place the seasoned steak into the hot skillet. Sear for approximately 3-5 minutes per side for medium-rare, or adjust the time to your preferred level of doneness. Use a meat thermometer if you’re unsure; 130-135°F (54-57°C) is a good target for medium-rare. Once seared, remove the steak from the skillet and place it on a clean cutting board. Tent it loosely with aluminum foil and let it rest for at least 10 minutes. This resting period is essential for allowing the juices to redistribute throughout the steak, ensuring a tender and moist result. If you cut into it too soon, all those delicious juices will run out onto the cutting board.
Cook the Pasta
Boil and Drain
While the steak is resting, it’s time to get our pasta ready. Bring a large pot of generously salted water to a rolling boil over high heat. Add the 12 oz of fettuccine pasta to the boiling water. Stir the pasta immediately to prevent it from sticking together. Cook the fettuccine according to the package directions until it is al dente, which means it should be tender but still have a slight bite to it. Overcooked pasta can become mushy and won’t hold up well in the rich Alfredo sauce.
Before draining the pasta, reserve about 1 cup of the starchy pasta water. This water is liquid gold for our sauce! It contains starch that will help to emulsify the sauce, making it wonderfully creamy and helping it cling to the fettuccine. Drain the cooked fettuccine in a colander and set it aside. Do not rinse the pasta; the residual starch helps the sauce adhere better.
Create the Cajun Alfredo Sauce
Sauté Aromatics and Build Flavor
Return the same skillet you used for the steak to medium heat (you can wipe out any excess grease if needed, but a little leftover steak flavor is a good thing). Add the 2 tablespoons of unsalted butter. Once the butter has melted and is slightly foamy, add the minced garlic. Sauté the garlic for about 30-60 seconds until it’s fragrant. Be careful not to burn the garlic, as burnt garlic can impart a bitter flavor. Stir in the remaining 1 teaspoon of Cajun seasoning and the ½ teaspoon of smoked paprika. Cook for another 30 seconds, stirring constantly, until the spices are fragrant. This bloom of the spices in the butter will release their full aroma and flavor.
Pour in the 1½ cups of heavy cream. Bring the cream to a gentle simmer, stirring occasionally. Allow the cream to simmer for about 3-5 minutes, or until it begin extracts to thicken slightly. This initial thickening is important before adding the cheese. Gradually whisk in the 1 cup of grated Parmesan cheese, a little at a time, stirring continuously until it’s fully melted and incorporated. Continue to cook and stir until the sauce is smooth and creamy. If the sauce becomes too thick at any point, you can loosen it with a tablespoon or two of the reserved pasta water. Season the sauce with salt and freshly ground black pepper to your liking. Remember that the Parmesan cheese is already salty, so taste before adding too much salt.
Assemble and Serve
Combine and Garnish
Add the drained fettuccine pasta directly into the skillet with the Cajun Alfredo sauce. Toss gently to coat the pasta evenly with the creamy sauce. If the sauce seems a bit too thick, add a splash more of the reserved pasta water until you reach your desired consistency. The sauce should cling beautifully to the strands of fettuccine.
Slice the rested steak against the grain into ½-inch thick strips. Arrange the sliced Cajun steak over the top of the sauced fettuccine. For a vibrant and fresh finish, sprinkle generously with freshly chopped parsley. Serve immediately and enjoy the rich, spicy, and creamy flavors of your homemade Cajun Steak Alfredo!

Frequently Asked Questions:
Q: Can I make the Cajun Steak Alfredo ahead of time?
While the components can be prepped, it’s best to assemble and cook the Alfredo sauce and steak just before serving for the freshest taste and best texture. The sauce can become slightly oily if reheated extensively, and the steak is always most tender when cooked to order.
Q: What kind of steak is best for Cajun Steak Alfredo?
For optimal tenderness and flavor, cuts like sirloin, ribeye, or New York strip are excellent choices. Ensure they are well-marbled for juiciness. Cut the steak against the grain for maximum tenderness after cooking.
