- 8 ounces penne pasta: Holds the Alfredo sauce beautifully while providing a satisfying bite.

- 1 pound top sirloin steak (cut into cubes): Offers hearty, tender meatiness that pairs amazingly with the creamy sauce.
- ½ cup unsalted butter: The rich base that melts into a luscious sauce.
- 2 cups heavy whipping cream: Creates the velvety texture that makes Alfredo sauce so irresistible.

How to Make Blackened Steak and Shrimp Alfredo Recipe
Step 1: Cook the Pasta
Start by boiling the penne pasta until it’s al dente, meaning it should be tender but still firm to the bite. This is crucial because it ensures your pasta won’t become mushy once tossed with the sauce. Drain the pasta and set it aside while you prepare the steak and shrimp.
Step 2: Blacken the Shrimp
Heat some vegetable oil in a skillet over medium-high heat, then generously season your shrimp with blackened seasoning. Cook them for about 2 to 3 minutes on each side until they turn a gorgeous pink and develop that signature charred crust. Remove the shrimp and keep them warm—this step sets the foundation for the dish’s bold flavor profile.
Step 3: Sear the Steak
Using the same skillet to capture all those delicious flavors, sear your cubed sirloin steak, coated with blackened seasoning, for about 3 to 4 minutes each side. Whether you like it medium-rare or well done, aim for a caramelized crust to add depth and texture. Once cooked to your liking, set the steak aside alongside the shrimp.
Step 4: Prepare the Alfredo Sauce
In your skillet, melt the butter over medium heat and sauté diced onion until soft and translucent—this soft sweetness is the subtle base for the sauce. Add minced garlic and let it infuse the butter for a brief moment before pouring in the heavy cream. Let the cream simmer gently for around 5 minutes, then gradually whisk in the freshly grated Parmesan cheese until you achieve a silky smooth sauce that will coat every morsel perfectly.
Step 5: Combine Everything
Now the magic happens. Toss the cooked penne pasta into the sauce, followed by the blackened shrimp and steak. Stir everything together to ensure each bite bursts with creamy goodness and smoky, spicy flavor. Season with kosher salt and freshly cracked black pepper to taste, then garnish with fresh parsley for a pop of color and herbaceous brightness just before serving.
How to Serve Blackened Steak and Shrimp Alfredo Recipe
Garnishes
A sprinkle of freshly chopped parsley is a classic choice, adding a lovely contrast with its bright green color and fresh aroma. You can also try adding a few red pepper flakes for extra heat or a grating of more Parmesan cheese on top to fan the flavors even further.
Side Dishes
This dish is rich and filling on its own, but pairing it with a crisp side salad tossed in a light vinaigrette or some roasted garlic broccoli cuts through the richness beautifully. Garlic bread or a warm baguette are also excellent options to help scoop up every bit of that dreamy Alfredo sauce.
Creative Ways to Present
For a dinner party, try serving the pasta in mini cast iron skillets or decorative bowls to keep it warm and create a rustic appeal. You can also plate individual portions with a drizzle of extra virgin olive oil and a lemon wedge on the side to brighten the palate after the creamy sauce.
Make Ahead and Storage
Storing Leftovers
If you’re lucky enough to have leftovers, store them in an airtight container in the refrigerator for up to 3 days. The flavors actually deepen overnight, but keep the pasta tightly sealed to prevent the sauce from drying out.
Freezing
Freezing is not ideal for this dish due to the cream-based sauce which can separate and become grainy. If you do freeze, place it in a freezer-safe container and consume within 1 month, but expect to reheat carefully.
Reheating
To reheat, warm the Blackened Steak and Shrimp Alfredo Recipe gently on the stove over low heat, stirring occasionally. Add a splash of cream or milk to help restore the sauce’s creamy texture and prevent it from drying out. Microwave reheating is possible but less ideal as it can unevenly heat and toughen the shrimp and steak.
FAQs
What type of steak works best for this recipe?
Top sirloin is fantastic because it’s tender yet flavorful and holds up well when cubed and seared quickly. You can also use ribeye for a richer taste or flank steak if you prefer a leaner cut.
Can I use a different type of pasta?
Absolutely! While penne is recommended because it traps the sauce nicely, you can also use fettuccine, linguine, or even rigatoni depending on your preference.
How spicy is the blackened seasoning?
The heat level can be adjusted to your liking since blackened seasoning often includes paprika, cayenne, garlic powder, and other spices. You can make it mild or pack a punch by increasing the cayenne powder.
Is this recipe suitable for weeknight dinners?
Yes! With just about 35 minutes from start to finish, it’s surprisingly quick for a dish that looks and tastes gourmet. Plus, your stovetop does most of the work without complicated techniques.
Can I make the Alfredo sauce dairy-free?
Making a dairy-free version is tricky because Parmesan and heavy cream are key to the sauce’s flavor and texture, but you can try using coconut milk and nutritional yeast as substitutes with varying results.
Final Thoughts
This Blackened Steak and Shrimp Alfredo Recipe is a game-changer for anyone who loves a hearty, flavorful pasta dish that feels special every time.
