The pasta is coated in a light beige creamy sauce with specks of black pepper and green parsley scattered on top. Orange-pink shrimp are spread evenly around the pan, and the dark brown, seared meat cubes add contrast. A silver spoon rests inside the pan on the right side, partially covered with pasta and sauce.

The ingredients for this dish are surprisingly simple but essential to achieving that perfect balance of flavor and texture. Each one plays an important role—from the peppery blackened seasoning that adds the signature boldness, to the creamy parmesan that gives the sauce its richness. Here's what I gather every time I make this:

8 ounces penne pasta: The tubular shape holds the creamy sauce wonderfully.
1 pound large shrimp, raw and deveined: Adds succulent seafood flavor without overpowering the dish.
1 teaspoon blackened seasoning (plus more): The heart of the dish’s smoky, spicy character.
1 tablespoon vegetable oil: For searing the shrimp and locking in flavor.
1 pound top sirloin steak, cut into 1-inch cubes: Tender, juicy, and perfect for quick cooking.
¼ cup unsalted butter: Adds richness to the sauce and helps cook the steak.
1 small yellow onion, diced: Soften to add subtle sweetness and depth.
2 teaspoons minced garlic: Always elevates savory dishes with warm, aromatic notes.
2 cups heavy whipping cream: Creates that luxuriously smooth Alfredo base.
2 cups freshly grated parmesan cheese: Provides sharpness and creamy thickness.
½ teaspoon kosher salt and ½ teaspoon black pepper: To season and balance the flavors.
Chopped parsley: For a fresh, vibrant garnish that brightens the plate.

Directions

Step 1: Bring a large pot of salted water to a vigorous boil over medium-high heat. Add the penne pasta and cook until al dente, which should take about 9-11 minutes depending on the brand. Usually, I taste a piece a minute before the suggested time to get that perfect bite. Reserve 1 cup of the pasta cooking water before draining the rest and set the pasta aside.

Step 2: While the pasta cooks, evenly season the raw shrimp with 1 teaspoon of blackened seasoning. Heat vegetable oil in a large 13-inch skillet over medium heat until shimmering. Add the shrimp and cook for about 1-2 minutes per side, until they turn pink and slightly crisp on the edges. Remove the shrimp from the skillet and tent them with foil to keep warm on a plate.

Step 3: Next, season the top sirloin steak cubes with another teaspoon of blackened seasoning. Turn the heat in the skillet up to high and add butter. Once the butter melts and starts to bubble, carefully add the steak cubes. Sear them for 1-2 minutes per side until they develop a nice brown crust on the outside but remain pink inside for juicy tenderness. Then transfer the steak to the plate with the shrimp and cover loosely to keep warm.

Step 4: Reduce the heat to medium and add the diced onions to the skillet. Cook for 3-5 minutes until they soften and become translucent, stirring occasionally to prevent sticking. Add the minced garlic and sauté for one minute until fragrant—this builds a beautiful base for the sauce.

Step 5: Pour in the heavy cream along with ¼ to ½ cup of the reserved pasta water. Stir in the freshly grated parmesan cheese, 1 tablespoon blackened seasoning, salt, and black pepper. Keep stirring until the cheese fully melts and the sauce thickens slightly. If the sauce is too thick, add more pasta water little by little until you reach your desired creaminess.

Step 6: Toss the cooked penne noodles gently in the Alfredo sauce, allowing each piece to get coated perfectly. Finally, nest the blackened steak and shrimp on top of the pasta. Sprinkle generously with chopped parsley for a finishing touch of color and freshness. Serve immediately while everything is warm and delicious.

How to Serve This Blackened Steak and Shrimp Alfredo Recipe

When I serve this dish, I like to keep the sides light and complementary so the bold flavors of the blackened steak and shrimp really shine through. A crisp green salad with a tangy vinaigrette or a simple roasted vegetable medley works wonderfully. I especially love pairing it with garlic bread or crusty Italian bread to soak up every bit of that creamy Alfredo sauce.

Presentation is fun with this one because the vibrant steak and shrimp contrast beautifully against the pale sauce and pasta. I like to plate the pasta first, then artfully arrange the pieces of steak and shrimp on top, finishing with a generous sprinkle of fresh parsley for color. A few red pepper flakes or a lemon wedge on the side add an optional extra pop of flavor and brightness.

As for drinks, I often go for a chilled glass of Sauvignon Blanc or a crisp Chardonnay because the acidity balances the richness of the dish perfectly. For something non-alcoholic, sparkling water with a wedge of lime or a homemade iced tea with a splash of lemon keeps the meal refreshing. I find this recipe works well for everything from casual weeknight family dinners to celebratory occasions where you want to impress with ease. Serving it hot is best to appreciate the creamy texture and fresh flavors.

Variations

I love experimenting with this Blackened Steak and Shrimp Alfredo Recipe to tailor it to different tastes and dietary needs. For example, if you want to switch up the protein, grilled chicken or even blackened fish filets can be fantastic alternatives to steak and shrimp. If seafood isn’t your thing, just doubling the steak or adding smoky sausage creates a hearty twist.

For those needing a gluten-free option, I usually substitute the penne with gluten-free pasta varieties, like those made from rice or chickpeas, and ensure the blackened seasoning is gluten-free. Vegan or dairy-free versions are also doable—I like replacing heavy cream with full-fat coconut milk and using nutritional yeast instead of parmesan cheese, paired with plant-based butter for a lovely creamy sauce.

To adjust the flavor profile, adding a splash of white wine to the sauce before the cream or stirring in some sun-dried tomatoes or roasted red peppers gives it a deliciously different character. Cooking methods can also vary; try grilling the steak and shrimp instead of pan-searing for a smokier charred flavor that adds another layer of complexity to the dish.

Storage and Reheating

Storing Leftovers

If you have leftovers, I recommend transferring the Blackened Steak and Shrimp Alfredo to an airtight container and placing it in the refrigerator. It will keep well for up to 3 days. Because the sauce is rich and creamy, make sure the container seals tight to prevent the pasta from drying out or absorbing other fridge odors.

Freezing

This dish is not the best candidate for freezing due to the creamy Alfredo sauce, which can separate when thawed. However, if you want to freeze it, do so without the seafood and steak first—freeze the pasta and sauce separately in airtight, freezer-safe containers or bags for up to one month. When you’re ready, thaw overnight in the fridge and add freshly cooked shrimp and steak to maintain the best texture and flavor.

Reheating

To reheat, I prefer warming it gently on the stovetop over low to medium heat, stirring frequently to prevent sticking and to gradually bring back the creamy texture. Adding a splash of milk or reserved pasta water helps revive the sauce. Avoid using the microwave when possible, since it can cause uneven heating and dry out the proteins. Reheat just until everything is thoroughly warmed to keep the shrimp and steak tender and avoid overcooking.

FAQs

Can I use other types of pasta for this recipe?

Absolutely! While penne is excellent at holding the sauce, you can also use fettuccine, linguine, or even rigatoni. Just make sure to cook the pasta al dente so it doesn’t become mushy when tossed in the sauce.

Is blackened seasoning very spicy?

Blackened seasoning has a bold, smoky flavor with a moderate kick of heat from paprika and cayenne, but it’s usually not overwhelmingly spicy. You can adjust the amount used based on your heat tolerance or try making your own mix to control the spice level.

Can I prepare parts of this recipe ahead of time?

You can definitely marinate and season the steak and shrimp a few hours before cooking to build flavor. You can also grate the parmesan and prep the onions and garlic in advance to streamline cooking day. However, for the best texture, I recommend cooking and assembling the dish just before serving.

What can I substitute if I don’t have heavy cream?

If heavy cream isn’t on hand, you can substitute it with half-and-half mixed with a little butter or use whole milk thickened with a bit of flour or cornstarch. Keep in mind the sauce may be slightly less rich, but still delicious.

Is this recipe suitable for a romantic dinner?

Definitely! The combination of steak and shrimp with a creamy, flavorful sauce makes this dish feel indulgent and special, perfect for a date night or celebratory dinner. Pair it with some candlelight and a good bottle of wine, and you have a winning meal.
