This is the “heavy hitter” of comfort food. Itβs bold, creamy, and unashamedly decadent. The key to a great Cajun Surf & Turf Alfredo is ensuring the steak and shrimp are seared perfectly so their juices meld into the cream sauce, creating that signature sunset-orange tint.
Here is how to pull it off like a pro.
The Flavor Profile
-
The Heat: Cajun seasoning (paprika, cayenne, garlic powder, oregano).
-
The Richness: A base of heavy cream and real Parmesan cheese.
-
The Texture: Al dente pasta, succulent shrimp, and tender, seared steak bites.
Ingredients List
| Component | Ingredients |
| The Protein | 1/2 lb Large Shrimp (peeled/deveined), 1/2 lb Sirloin or Ribeye (cubed) |
| The Pasta | 8 oz Fettuccine or Penne |
| The Sauce | 2 cups Heavy Cream, 4 tbsp Butter, 1 cup Grated Parmesan |
| The Aromatics | 3 cloves Garlic (minced), 1/2 Bell Pepper (diced), 1/2 Onion (diced) |
| The Spice | 2 tbsp Cajun Seasoning (divided), Smoked Paprika, Fresh Parsley |
Step-by-Step Execution
1. Sear the Proteins
Season your steak cubes and shrimp generously with 1 tablespoon of the Cajun seasoning.
-
Steak First: In a large skillet over high heat, sear the steak bites in a splash of oil until browned (about 2 minutes per side). Remove and set aside.
-
Shrimp Second: In the same pan, sear the shrimp until pink and opaque (about 1-2 minutes per side). Remove and set aside with the steak. Don’t wash the pan! Those brown bits (the fond) are flavor gold.
2. SautΓ© the Aromatics
Lower the heat to medium. Add the butter to the skillet. SautΓ© the onions and bell peppers until soft, then add the garlic for the last 30 seconds so it doesn’t burn.
3. Build the Alfredo
Pour in the heavy cream and the remaining Cajun seasoning. Bring to a gentle simmer (do not boil rapidly or the cream might break). Let it reduce slightly for 3-5 minutes.
4. The Cheese Melt
Whisk in the Parmesan cheese slowly. Stir constantly until the sauce is thick and velvety.
5. The Final Toss
Add your cooked pasta directly into the sauce. Fold the steak and shrimp (and any juices on the plate) back into the pan. Toss everything together until the pasta is coated in that spicy, creamy goodness.
π‘ Tips for a Better Pasta
-
Pasta Water: Save a half-cup of the salty pasta water before draining. If your Alfredo gets too thick, a splash of this water will make it silky again.
-
The Steak Cut: Use a tender cut like Ribeye or Filet Mignon if budget allows. If using Sirloin, slice it against the grain into thin strips so it stays tender during the quick sear.
-
Salt Warning: Cajun seasoning blends are often very heavy on salt. Taste your sauce before adding any extra salt!
