Step-by-Step Instructions
Step 1: Cook the Pasta
Bring a large pot of salted water to a boil. Cook pasta according to package directions until al dente.
Reserve 1/2 cup pasta water, then drain.
Step 2: Season the Steak
Toss steak strips with olive oil, Cajun seasoning, salt, and pepper.
Step 3: Sear the Steak
Heat a large skillet over medium-high heat. Add butter (and smashed garlic if using).
Sear steak for 2–3 minutes per side until browned and cooked to your liking. Transfer to a plate and cover loosely.
Step 4: Cook the Shrimp
In the same skillet, add olive oil and butter. Season shrimp with Cajun seasoning, salt, and pepper.
Cook shrimp 1–2 minutes per side until pink and opaque. Remove and set aside.
Step 5: Make the Creamy Parmesan Sauce
Lower heat to medium. Add butter and minced garlic, sauté for 30 seconds.
Pour in heavy cream and simmer gently for 3–4 minutes (don’t boil hard).
Stir in Parmesan until melted and smooth. Add black pepper and Cajun seasoning (if using).
If sauce is too thick, add a splash of reserved pasta water.
Step 6: Combine Everything
Add cooked pasta to the sauce and toss until coated.
Fold in steak and shrimp (and any juices on the plate). Heat for 1 minute until warmed through.
Step 7: Serve
Plate immediately and finish with parsley, extra Parmesan, and a squeeze of lemon if desired.
Serving Suggestions

- Pair with a crisp side salad (Caesar or mixed greens).
- Add roasted broccoli or asparagus for a balanced plate.
- For extra flavor, sprinkle with red pepper flakes and more Cajun seasoning.
- Serve with lemon wedges to brighten the shrimp and cut the richness.

Tips for Perfect Cajun Alfredo
- Don’t overcook shrimp—remove as soon as it turns pink.
- Use freshly grated Parmesan for a smooth sauce (pre-shredded can clump).
- Keep heat moderate—Alfredo can split if boiled aggressively.
- Reserve pasta water—it helps thin the sauce while keeping it silky.
- Taste your Cajun seasoning first (some are saltier/spicier than others).
Variations to Try
- Chicken + Shrimp Alfredo: Swap steak for sliced chicken breast.
- Spicier Version: Add cayenne or extra Cajun seasoning.
- Lighter Sauce: Use half-and-half and reduce butter by 1 tablespoon.
- Veggie Add-In: Stir in sautéed mushrooms, spinach, or roasted peppers.
- Low-Carb Option: Serve sauce over zucchini noodles or cauliflower pasta.
