This Cajun Shrimp and Steak Alfredo Pasta is a perfect mix of bold and creamy flavors. You get tender pieces of juicy steak and spicy shrimp all tossed in a rich, cheesy Alfredo sauce, wrapped around your favorite pasta. The Cajun seasoning adds just the right kick to make this dish exciting without overpowering the smoothness of the sauce.
I love making this dish when I want something comforting but still a little special. The combination of seafood and steak with the creamy sauce always surprises people, and I find that the spicy Cajun touch keeps it interesting bite after bite. It’s like a little party in your mouth every time you dig in.
One of my favorite ways to serve this is with a simple green salad on the side and a sprinkle of fresh parsley on top to brighten up the plate. It feels like a restaurant meal but is easy enough to whip up on a weeknight after a busy day. Whether it’s dinner for family or friends, everyone tends to ask for seconds when this pasta is on the table!
Key Ingredients & Substitutions
Shrimp: Fresh or frozen shrimp both work fine here. If you’re allergic or don’t eat seafood, chicken breast cut into cubes is a good swap. Just season it well with Cajun spices.
Steak: Sirloin or ribeye are great because they stay tender. You can also use flank or skirt steak for more flavor but slice it thinly against the grain.
Cajun Seasoning: This spice blend is what brings the dish alive. If you don’t have a mix, combine paprika, garlic powder, onion powder, cayenne, oregano, thyme, salt, and pepper.
Alfredo Sauce (Butter, Cream, Milk, Parmesan): For a lighter version, try half-and-half instead of heavy cream. Use grated Romano cheese if Parmesan isn’t available for a slightly different taste.
Pasta: Penne or fettuccine both hold the sauce well. You can also use linguine or spaghetti for a twist, just cook al dente and drain well.
How Do You Cook Shrimp and Steak Perfectly Without Overcooking?
The key is cooking each protein quickly over medium-high heat in batches to get a good sear without steaming or drying out.
- Shrimp: Cook for 2-3 minutes per side until pink and just opaque. They cook fast, so watch closely and pull them off as soon as they change color.
- Steak: Cut steak into similar-sized cubes for even cooking. Sear on each side for 3-4 minutes depending on thickness and how you like it.
- Rest your steak cubes a few minutes after cooking to keep juices locked in.
- Use the same pan for shrimp and steak to build those deep flavors from the browned bits left behind.
Equipment You’ll Need
- Large pot – To cook your pasta until al dente.
- Large skillet or frying pan – Perfect for searing the shrimp and steak, plus making the creamy sauce.
- Bowls – For tossing the shrimp and steak with seasonings.
- Measuring spoons and cup – To measure spices, cream, and cheese accurately.
- Grater – To grate fresh Parmesan cheese for the best flavor.
- Cooking utensils – Such as tongs or a spatula, to handle proteins and toss pasta.
Flavor Variations & Add-Ins
- Use cooked chicken instead of shrimp or steak for a different protein option.
- Add sautéed vegetables like bell peppers, onions, or spinach for extra color and nutrients.
- Include a splash of lemon juice or zest to brighten up the dish.
- Top with chopped green onions or fresh basil for a fresh herb boost.

How Much Time Will You Need?
This recipe takes about 30 minutes total. You’ll spend around 10-12 minutes cooking the pasta, 10 minutes to prepare and sear the shrimp and steak, and 8-10 minutes making the creamy Alfredo sauce and combining everything together. It’s a quick and satisfying meal!
Step-by-Step Instructions:
1. Cook the Pasta:
Fill a large pot with water and add a pinch of salt. Bring it to a boil, then add your pasta. Cook according to the package instructions until al dente (firm to the bite). Drain the pasta and set it aside while you prepare the rest.
2. Season and Cook the Shrimp and Steak:
In a medium bowl, toss the shrimp with 1 teaspoon of Cajun seasoning and a pinch of salt and pepper. In another bowl, toss the steak cubes with the remaining 1 teaspoon of Cajun seasoning, salt, and pepper. Heat half the olive oil in a large skillet over medium-high heat. Add the shrimp and cook about 2-3 minutes per side until they turn pink and are cooked through. Remove shrimp and set aside. Add the rest of the olive oil to the skillet, then add the steak cubes. Sear them for about 3-4 minutes per side until browned and cooked to your liking. Remove steak from the skillet and set aside.
3. Make the Alfredo Sauce:
Lower the heat to medium and add butter to the skillet. Once melted, add the minced garlic and sauté for about 1 minute until fragrant. Slowly pour in the heavy cream and whole milk, and gently bring it to a simmer. Gradually whisk in the Parmesan cheese until the sauce is smooth and creamy. If you like a bit more heat, stir in the crushed red pepper flakes. Taste and season with salt and pepper as needed.
4. Combine and Serve:
Add the cooked pasta to the Alfredo sauce and toss well to coat every bite. Plate the creamy pasta, then top it with the Cajun shrimp and seared steak cubes. Sprinkle freshly chopped parsley over the top for a fresh touch. Serve immediately and enjoy!
Can I Use Frozen Shrimp for This Recipe?
Yes! Just be sure to thaw the shrimp completely before cooking. The best way is to leave them in the fridge overnight or place the sealed bag in cold water for about 20-30 minutes. Pat them dry to avoid extra moisture in the pan.
How Can I Make This Recipe Dairy-Free?
You can substitute the heavy cream and milk with full-fat coconut milk or a dairy-free cream alternative. Use a vegan Parmesan substitute or nutritional yeast to keep that cheesy flavor while making it dairy-free.
Can I Prepare the Sauce Ahead of Time?
Absolutely! You can make the Alfredo sauce a day ahead and store it in the fridge. When ready to serve, gently reheat on the stove, adding a splash of milk or cream to loosen it up if it thickens too much.
What Is the Best Way to Store Leftovers?
Place leftover pasta with shrimp and steak in an airtight container and refrigerate for up to 3 days. Reheat gently on the stove or microwave, stirring occasionally to heat evenly. Adding a little cream or milk while reheating helps keep the sauce creamy.
