Cajun Shrimp and Steak Alfredo Pasta marries tender, spice-crusted steak strips and plump shrimp with silky fettuccine, all enveloped in a rich, creamy Parmesan sauce. The bold Cajun seasoning adds warmth and depth to this indulgent pasta dish, creating perfect bites where spice meets cream in a delightful dance of flavors.
When I first created this dish for my family's Sunday dinner, the way the Cajun spices balanced the creamy sauce was a revelation. Now it's become our go-to special occasion meal that everyone requests.
Essential Ingredients
- Steak: Choose ribeye or sirloin that's well-marbled - those tiny streaks of fat ensure tender, flavorful meat
- Shrimp: Look for large, pink shrimp that feel firm and smell fresh like the ocean
- Heavy cream: Full-fat cream creates the smoothest sauce that won't separate when heated
- Parmesan cheese: Buy a block and grate it fresh - pre-grated cheese often contains additives that can make your sauce grainy
- Cajun seasoning: Select a blend with a good balance of paprika, garlic, and herbs. The color should be vibrant red

Detailed Cooking Instructions
- 1. Pasta Perfection
- Salt your pasta water until it tastes like the sea
- Stir pasta immediately after adding to prevent sticking
- Reserve a full cup of pasta water before draining
- Toss pasta with a drizzle of olive oil if not using immediately
- 2. Protein Preparation
- Let steak come to room temperature for even cooking
- Pat both steak and shrimp completely dry before seasoning
- Season generously with Cajun spice, pressing it into the proteins
- Allow seasoned meat to rest for 10 minutes before cooking
Creating the Perfect Sear
- Steps
- Heat pan until droplets of water dance and evaporate instantly
- Place steak strips without overcrowding to ensure proper browning
- Resist moving the meat for the first 2-3 minutes
- Cook shrimp just until they curl into a loose 'C' shape
Sauce Building
- Steps
- Start with melted butter and let it foam slightly
- Add garlic only after reducing heat to prevent burning
- Pour cream in a steady stream while whisking constantly
- Add cheese gradually, stirring in a figure-eight motion for smoothness
The Art of Timing
Getting everything to come together hot and fresh takes practice. I've learned to start the pasta water first, then prep the proteins while it comes to a boil. The sauce comes last, as it stays creamy and hot while you quickly cook the steak and shrimp.

Mastering the Alfredo
The secret to silky Alfredo sauce lies in patience. I discovered that adding the cream gradually and letting each addition heat through before adding more prevents any graininess. When my grandmother taught me this technique, it completely transformed my sauce game.
Spice Balance
The beauty of Cajun seasoning is how it cuts through the richness of the Alfredo sauce. Each component should have its moment - the spice shouldn't overwhelm the cream, and the cream shouldn't dull the Cajun kick.
The first time I made this dish, I was amazed by how the Cajun seasoning transformed a classic Alfredo into something entirely new. My family particularly loves how the spices build with each bite.
