The Steak and Shrimp Pasta Recipe You Have Been Dreaming About
Imagine a bowl of silky, Parmesan-loaded Alfredo pasta crowned with seared, smoky slices of blackened steak and plump, spice-kissed shrimp. This Blackened Steak and Shrimp Alfredo is the kind of dish that makes a Tuesday feel like a special occasion. It is bold, deeply satisfying, and every single forkful delivers something worth savoring.
If you have ever searched for steak and shrimp pasta recipes that genuinely taste like something from a great restaurant, this is it. The magic here is in the layering of flavors: a smoky, garlicky Cajun blackening spice rub, a quick sear that builds a crackling crust on both the steak and shrimp, and then a velvety homemade Alfredo sauce that ties it all together. It is rich without being heavy, spicy without being aggressive, and absolutely spectacular.
Why This Cajun Steak and Shrimp Alfredo Works So Well
The secret to great steak and shrimp Cajun pasta is contrast. The heat and char from the blackening spices play beautifully against the cool, buttery creaminess of the Alfredo sauce. Neither one overwhelms the other. Instead, they lift each other up in a way that keeps every bite interesting from start to finish.
A few things make this particular recipe stand out:
- The blackening blend is homemade. It only takes a minute to mix, and it delivers far more complexity than anything from a pre-made packet.
- A cast-iron skillet is non-negotiable. It holds intense heat, which is exactly what you need to get that deep, slightly charred crust on the steak without overcooking the inside.
- Cream cheese in the Alfredo. This is the quiet trick that keeps the sauce incredibly smooth and stable, even after you toss the pasta in.
- Freshly grated Parmesan. Pre-shredded cheese contains anti-caking agents that prevent it from melting properly. Buy a block and grate it yourself. The sauce will be on another level.
The right tools and ingredients genuinely make the difference between a good pasta dish and an unforgettable one. A quality cast-iron skillet and a reliable microplane for the Parmesan are the two items that will serve you best here:
Building the Perfect Blackening Spice Blend
The blackened steak Alfredo flavor profile starts with a simple but punchy spice rub. Smoked paprika forms the base, delivering that deep, almost wood-fire character. Garlic powder, onion powder, oregano, and thyme round it out with savory warmth, while cayenne brings the heat. It is assertive but balanced, and it works equally well on the steak and the shrimp.
Chef's Tip: Pat your steak completely dry with paper towels before applying the spice rub. Moisture is the enemy of a good sear. A dry surface means a better crust, and a better crust means more flavor.
You can make a double or triple batch of the spice blend and store it in a sealed jar for up to a month. It is fantastic on chicken, salmon, or roasted vegetables too.
How to Sear Steak and Shrimp Like a Pro
For this steak shrimp Alfredo pasta, the proteins are cooked separately and then brought together on the plate. This gives you full control over each one.
For the steak: Get your cast-iron skillet screaming hot before the steak goes in. You want to hear a loud, confident sizzle the moment it hits the pan. Do not move it. Let the crust build for 3 to 4 minutes, flip once, and finish. Then let it rest. Resting is not optional. Five minutes on the cutting board allows the juices to redistribute so the steak stays tender and juicy when you slice it.
For the shrimp: Shrimp cook in under 3 minutes total. They are done the moment they turn pink and curl into a loose C shape. An O shape means they are overcooked. Work in a single layer so they sear rather than steam, and pull them off the heat immediately.
Chef's Tip: Cook the shrimp in the same pan right after the steak. All those browned bits and rendered fat left behind will flavor the shrimp beautifully without any extra effort.
The Alfredo Sauce: Rich, Silky, and Impossible to Resist
This is not a jarred sauce situation. The homemade Alfredo for this shrimp and steak Alfredo pasta comes together in about 10 minutes and is leagues above anything from a bottle.
The method is simple: build a garlicky butter base in the same skillet you used for the proteins (all that flavor hiding in those browned bits goes straight into your sauce), pour in heavy cream, melt in a little cream cheese for body, then pull the pan off the heat before stirring in the Parmesan. Taking the pan off the heat before adding the cheese prevents it from clumping or turning grainy.
The result is a sauce that coats every strand of fettuccine in a glossy, deeply savory blanket.

Blackened Steak and Shrimp Alfredo
This Blackened Steak and Shrimp Alfredo is a bold, restaurant-worthy pasta dish featuring smoky Cajun-spiced steak and juicy shrimp tossed in a rich, creamy Alfredo sauce. It's the ultimate steak and shrimp pasta recipe for a special weeknight dinner or date night at home.
Ingredients
- 12 oz fettuccine pasta, dry
- 1 lb ribeye or sirloin steak, about 1 inch thick, patted dry
- 1 lb large shrimp, peeled and deveined, tails off
- 1 1/2 tsp smoked paprika
- 1 tsp garlic powder
- 1/2 tsp onion powder
- 1/2 tsp cayenne pepper, adjust to heat preference
- 1/2 tsp dried oregano
- 1/2 tsp dried thyme
- 1 tsp kosher salt, divided
- 1/2 tsp black pepper, freshly ground
- 3 tbsp unsalted butter, divided
- 2 tbsp olive oil, divided
- 5 garlic cloves, minced
- 2 cups heavy cream
- 1 1/2 cups Parmesan cheese, freshly grated, plus more for serving
- 2 oz cream cheese, softened, for extra richness
- 1/2 cup pasta cooking water, reserved before draining
- 2 tbsp fresh parsley, chopped, for garnish
Instruction
Bring a large pot of well-salted water to a boil. Cook the fettuccine according to package directions until al dente. Reserve 0.5 cup of pasta water before draining, then drain and set aside.
In a small bowl, combine the smoked paprika, garlic powder, onion powder, cayenne, oregano, thyme, 0.5 tsp salt, and black pepper to make the blackening spice blend.
Pat the steak completely dry with paper towels. Rub both sides generously with half of the blackening spice blend, pressing it into the surface.
Toss the shrimp with the remaining blackening spice blend and a pinch of salt in a bowl. Set aside.
Heat a large cast-iron skillet over high heat until it begins to smoke. Add 1 tbsp olive oil and 1 tbsp butter. Sear the steak for 3 to 4 minutes per side for medium-rare, or until your preferred doneness is reached. Transfer to a cutting board and let it rest for at least 5 minutes before slicing against the grain into thin strips.
In the same skillet, reduce heat to medium-high. Add 1 tbsp olive oil. Add the seasoned shrimp in a single layer and cook for 1 to 2 minutes per side until pink and just cooked through. Remove from the skillet and set aside.
Reduce heat to medium. Add the remaining 2 tbsp butter to the skillet. Once melted, add the minced garlic and cook for about 60 seconds, stirring constantly, until fragrant.
Pour in the heavy cream, scraping up any browned bits from the bottom of the pan. Add the softened cream cheese and stir until fully melted and smooth. Simmer for 3 to 4 minutes until the sauce begins to thicken slightly.
Remove the skillet from heat and stir in the freshly grated Parmesan a handful at a time, stirring after each addition until fully melted and the sauce is silky. If the sauce is too thick, loosen it with a splash of the reserved pasta water.
Add the drained fettuccine to the sauce and toss well to coat every strand. Taste and adjust salt as needed.
Plate the pasta and top each serving with sliced blackened steak and a few shrimp. Garnish with fresh parsley and extra Parmesan. Serve immediately.

Notes
Serving, Storing, and Making It Your Own
This steak and shrimp Alfredo is best served immediately, right out of the pan while the sauce is at its most luxurious. Pile it into wide, shallow bowls, layer the steak slices and shrimp on top, and finish with a cloud of extra Parmesan and a handful of fresh parsley.
Want to customize it?
- Make it extra smoky: Add a strip or two of crispy bacon to the pasta before plating.
- Add vegetables: Wilted spinach, roasted cherry tomatoes, or sauteed mushrooms all work beautifully stirred into the sauce.
- Dial back the richness: Swap half the heavy cream for whole milk and skip the cream cheese for a lighter, though still deeply satisfying, version.
- Switch the protein: This same blackening technique and Alfredo sauce is equally stunning with chicken breast or even scallops in place of the steak.
Leftovers store well in the fridge for up to 3 days. Reheat low and slow with a splash of cream to bring the sauce back to its original silkiness. Whatever you do, do not rush the reheat.
