Pasta
8 ounces penne pasta

Shrimp
1 pound large raw shrimp, deveined and tails removed
1 teaspoon blackened seasoning
1 tablespoon vegetable oil

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

Sauce
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
½ teaspoon kosher salt
½ teaspoon black pepper
2 to 4 tablespoons reserved pasta water (as needed for consistency)
Fresh parsley, chopped, for garnish

Directions

1. Bring a large pot of salted water to a boil over medium-high heat. Cook the penne pasta al dente according to package instructions.
2. Reserve 1 cup of pasta water, then drain the pasta and set aside.

Shrimp
3. Pat the shrimp dry and season evenly with 1 teaspoon blackened seasoning.
4. Heat vegetable oil in a large 12- to 13-inch skillet over medium heat.
5. Add the shrimp in a single layer and cook for 1 to 2 minutes per side, until pink and opaque.
6. Transfer the shrimp to a plate and loosely cover to keep warm.

Steak
7. Season the cubed sirloin with 1 teaspoon blackened seasoning.
8. Increase the heat to high and add the butter to the same skillet.
9. Once melted, add the steak in a single layer. Cook for 1 to 2 minutes per side, until browned on the outside and still slightly pink inside, or to your preferred doneness.
10. Remove the steak and place it on the plate with the shrimp. Cover loosely to keep warm.

Sauce
11. Reduce the heat to medium and add the diced onion to the skillet. Cook for 3 to 5 minutes, until softened.
12. Stir in the minced garlic and cook for 1 minute until fragrant.
13. Pour in the heavy whipping cream and add ¼ cup of the reserved pasta water.
14. Stir in the parmesan cheese, 1 tablespoon blackened seasoning, kosher salt, and black pepper.
15. Cook, stirring constantly, until the cheese is melted and the sauce thickens slightly.
16. Add the cooked pasta to the skillet and toss to coat evenly. Add additional pasta water, a tablespoon at a time, if needed to loosen the sauce.
17. Return the shrimp and steak to the skillet, placing them over the pasta.
18. Garnish with chopped parsley and serve immediately.

Variations

• Swap top sirloin for ribeye, tenderloin, or strip steak for a different texture and richness.
• Use fettuccine or cavatappi instead of penne for a classic Alfredo feel.
• Add sautéed mushrooms or spinach for extra flavor and color.
• Make it extra spicy by increasing the blackened seasoning slightly.
• Lighten it up by substituting half-and-half for part of the heavy cream, keeping in mind the sauce will be less thick.

Storage/Reheating

Allow the pasta to cool to room temperature before storing. Transfer to an airtight container and refrigerate for up to 3 to 4 days.

To reheat, warm gently on the stovetop over low heat, adding a splash of milk or cream to loosen the sauce. You can also reheat in the microwave in 30-second intervals, stirring between each interval until heated through.

Freezing is not recommended, as cream-based sauces may separate when thawed.

FAQs

Can I use precooked shrimp?

Yes, you can use precooked shrimp. Simply season them and warm them in the skillet for 1 to 2 minutes before removing. Avoid overcooking to prevent a rubbery texture.

What is blackened seasoning made of?

Blackened seasoning typically includes paprika, garlic powder, onion powder, dried herbs, salt, black pepper, and cayenne pepper for heat.

How do I keep the steak tender?

Avoid overcooking and let the steak rest briefly after cooking. Cutting it into even 1-inch cubes helps it cook quickly and evenly.

Can I make this dish less spicy?

Yes. Start with half the amount of blackened seasoning and adjust to taste after the sauce is prepared.

What pasta works best for Alfredo?

Penne, fettuccine, and cavatappi all work well because they hold the creamy sauce nicely.

Can I prepare this ahead of time?

You can cook the components ahead and store them separately. Reheat gently and combine just before serving for best results.

Why is my Alfredo sauce too thick?

If the sauce becomes too thick, stir in a bit of reserved pasta water, milk, or cream until it reaches your desired consistency.

Why did my sauce turn grainy?

Grainy sauce can happen if the cheese is added over very high heat. Lower the heat and stir continuously while adding the cheese.

Can I use a different cheese?

Freshly grated parmesan is best, but you can mix in a small amount of Romano or Asiago for added depth of flavor.

Is this recipe suitable for special occasions?

Absolutely. The combination of steak, shrimp, and creamy Alfredo sauce makes it elegant enough for gatherings, celebrations, or a special family dinner.

Conclusion

Blackened Steak and Shrimp Alfredo is the ultimate comfort meal with a bold twist. Tender steak, perfectly cooked shrimp, and a smoky, creamy Alfredo sauce come together in a dish that feels indulgent yet approachable.
