How to Make Blackened Steak and Shrimp Alfredo Recipe
Step 1: Cook Pasta
Start by bringing a large pot of salted water to a boil over medium-high heat. Add the penne pasta and cook until it reaches al dente according to package instructions. Don’t forget to reserve 1 cup of the pasta water before draining—that starchy liquid will be key for adjusting your sauce consistency later.
Step 2: Cook Shrimp
While the pasta cooks, season the shrimp evenly with 1 teaspoon of blackened seasoning. Heat 1 tablespoon of vegetable oil in a large 13-inch skillet over medium heat until it’s nice and hot. Cook the shrimp for about 1 to 2 minutes on each side until they turn pink and are just cooked through. Transfer them to a plate and tent with foil to keep warm while you move on to the steak.
Step 3: Cook Steak
Season the sirloin steak cubes with the remaining 1 teaspoon of blackened seasoning. Turn your heat to high in the same skillet, add the butter, and let it melt until it bubbles enticingly. Place the steak cubes in the skillet and sear for 1 to 2 minutes per side. You want that beautiful browned exterior while keeping the inside pink and juicy. Once done, transfer the steak to the plate with the shrimp, keeping them wrapped to stay warm.
Step 4: Make the Sauce
Lower the heat to medium and toss the diced onion into the skillet, cooking for 3 to 5 minutes until softened and fragrant. Next, add the minced garlic and stir for one minute. Pour in the heavy cream, ¼ to ½ cup of your reserved pasta water, and the freshly grated parmesan cheese. Stir in 1 tablespoon of blackened seasoning, kosher salt, and black pepper. Keep stirring gently until the cheese melts fully and your sauce thickens into a velvety, flavorful base.
Step 5: Toss Pasta in Sauce
Now the magic happens. Add the drained penne pasta into the skillet with the Alfredo sauce. Toss everything well to coat each piece of pasta with the creamy, spiced sauce. Feel free to add a little more reserved pasta water if you want a thinner consistency—this sauce should coat the pasta luxuriously without feeling heavy.
Step 6: Serve Dish
Finally, top your pasta with those succulent shrimp and beautifully seared steak cubes. Finish with a sprinkle of chopped parsley to add a fresh, green pop of color. Serve immediately so everyone enjoys the meal hot, creamy, and bursting with flavor.

Garnishes
Fresh chopped parsley is a classic and lively finishing touch, but you can also try fresh basil leaves or a light dusting of extra parmesan. A squeeze of lemon just before serving brightens the dish and complements the blackened spices wonderfully.
Side Dishes
This dish is rich and filling, so pair it with light, crisp sides like a simple arugula salad tossed with lemon vinaigrette or some steamed seasonal vegetables. Garlic bread or a warm baguette is also fantastic to mop up any leftover creamy sauce on your plate.
Creative Ways to Present
For a dinner party, serve the blackened steak and shrimp Alfredo over individual pasta nests or in shallow bowls so each guest can admire the gorgeous steak cubes and shrimp perched on top. Garnish with edible flowers or drizzle a bit of good quality olive oil for an elegant finish.
Make Ahead and Storage
Storing Leftovers
You can store leftover Blackened Steak and Shrimp Alfredo in an airtight container in the refrigerator for 3 to 4 days. Make sure to cool it to room temperature before sealing to maintain freshness and prevent condensation.
Freezing
While this dish is best enjoyed fresh, you can freeze leftovers for up to one month. Use a freezer-safe container and leave a little space at the top for expansion. When ready, thaw overnight in the refrigerator before reheating.
Reheating
To reheat, gently warm the Alfredo in a skillet over low heat, adding a splash of milk or reserved pasta water to loosen the sauce and prevent it from breaking. Heat slowly and stir often to maintain the creamy texture, and add the steak and shrimp on top once warmed through to avoid overcooking.
FAQs
Can I use a different type of pasta?
Absolutely! While penne is great for catching the sauce, fettuccine, rigatoni, or even linguine all work wonderfully with this creamy Alfredo recipe. Just cook them according to package directions.
Is blackened seasoning very spicy?
It packs a nice kick but nothing too overpowering. It adds smoky warmth and a bit of heat, balancing beautifully with the richness of the cream and parmesan.
Can I substitute the shrimp for another protein?
Definitely! Chicken breast or even scallops are excellent alternatives if shrimp isn’t your favorite. Just adjust cooking times accordingly to avoid overcooking.
Do I have to use heavy cream for the sauce?
Heavy cream is key for achieving the rich, silky texture in Alfredo sauce. You might try half-and-half for a lighter version, but it won’t be quite as smooth or thick.
Can I prepare any part of this dish in advance?
You can season and marinate the steak and shrimp earlier to save prep time. The sauce is best made fresh, but if needed, you can prepare it a few hours ahead and gently reheat when ready to serve.
