- 1 (10.75 oz) can condensed cream of mushroom soup: The base of the creamy Alfredo sauce, ensuring richness and depth.
- 1 cup milk: Used to thin the soup into a smooth, luscious sauce.
- 1/2 cup grated Parmesan cheese: Adds that unmistakable sharpness and melts into the sauce flawlessly.

How to Make Cajun Shrimp and Steak Alfredo Pasta Recipe
Step 1: Cook the Pasta
Start by cooking your penne pasta according to the package instructions until al dente. This step lays the foundation for the dish, so be sure to drain it well and set it aside to avoid any sogginess later on.
Step 2: Season the Steak and Shrimp
In a bowl, whisk together olive oil, paprika, garlic powder, and black pepper to make a vibrant seasoning mix. Coat the thinly sliced steak and peeled shrimp in this mixture. This seasoning blend is where the Cajun character truly shines, infusing the proteins with smoky warmth before they hit the pan.
Step 3: Cook the Steak
Heat a skillet or grill pan over medium-high heat, then cook the steak strips until they reach your preferred doneness—medium rare to medium works beautifully for tender, juicy results. Once cooked, transfer the steak to a plate and keep it warm.
Step 4: Cook the Shrimp
Using the same skillet, sauté the seasoned shrimp just until they turn pink and firm. Avoid overcooking them, as shrimp can quickly become rubbery. Remove from heat and set aside alongside the steak.
Step 5: Make the Alfredo Sauce
In a large skillet, combine condensed cream of mushroom soup, milk, Parmesan cheese, dried oregano, garlic powder, and black pepper. Gently simmer this mixture for 15 to 20 minutes, stirring occasionally until it thickens into a rich, creamy sauce that’s simply irresistible.
Step 6: Combine Ingredients
Add the cooked steak and shrimp directly into the Alfredo sauce, tossing to coat every morsel with that luscious creaminess. The sizzling flavors meld beautifully at this stage, making the dish come alive.
Step 7: Toss with Pasta
Finally, add the cooked penne pasta to the skillet and toss everything together until the sauce clings to each tube of pasta, creating a harmonious medley of textures and flavors. Serve immediately for the best taste and warmth.
How to Serve Cajun Shrimp and Steak Alfredo Pasta Recipe

Garnishes
Simple garnishes can elevate this dish to restaurant-worthy levels. Consider sprinkling freshly chopped parsley or a dusting of extra Parmesan on top. The green parsley adds a freshness and pop of color, perfectly balancing the richness of the sauce.
Side Dishes
Pair this hearty pasta with a crisp green salad dressed lightly in lemon vinaigrette to cut through the creaminess. Garlic bread or a warm baguette is another fantastic choice to sop up every last bit of the delicious sauce.
Creative Ways to Present
For a fun twist, serve this Cajun Shrimp and Steak Alfredo Pasta Recipe in individual shallow bowls, layering shrimp and steak on top as a beautiful garnish. Alternatively, use a large serving platter to showcase the vibrant colors and textures so everyone can dig in family-style.
Make Ahead and Storage
Storing Leftovers
After enjoying your meal, store any leftovers in an airtight container in the refrigerator for up to 3 days. The pasta will absorb some sauce overnight, so stir gently before reheating to bring back the creamy texture.
Freezing
This dish freezes well in portion-sized containers. Freeze within two hours of cooking and consume within two months for best flavor. When you thaw it, the creamy sauce might separate slightly but whisking during reheating will restore it nicely.
Reheating
Reheat leftovers on the stove over low heat, adding a splash of milk to loosen the Alfredo sauce if it has thickened too much. Stir frequently and avoid high heat to keep shrimp tender and prevent the steak from drying out.
FAQs
Can I use a different type of pasta for this recipe?
Absolutely! While penne is perfect for holding the sauce, other pasta shapes like fettuccine, rigatoni, or even bowtie pasta will work wonderfully depending on your preference.
What if I don’t have cream of mushroom soup on hand?
You can substitute with a homemade béchamel sauce or use cream of chicken soup for a subtle flavor variation. The sauce’s creaminess is key, so keep that in mind.
How spicy is this Cajun Shrimp and Steak Alfredo Pasta Recipe?
The heat level is moderate thanks to the cayenne pepper and paprika. If you prefer less heat, reduce the cayenne or skip it altogether. For extra spice, add a pinch of red pepper flakes when cooking the sauce.
Can I prepare the steak and shrimp ahead of time?
Yes! You can season and cook the proteins a few hours ahead and refrigerate. Just make sure to bring them to room temperature before combining with the sauce and pasta to keep everything warm and flavorful.
Is this recipe suitable for weeknight dinners?
Definitely. Despite its gourmet feel, this Cajun Shrimp and Steak Alfredo Pasta Recipe comes together in about 45 minutes, making it both impressive and practical for busy nights when you want something special.

This Cajun Shrimp and Steak Alfredo Pasta Recipe is hands down one of those dishes that feels decadent yet approachable, bold yet comforting.
