The Magic of Cajun Seasoning in Creamy Dishes

Cajun seasoning is a spice blend rooted in Louisiana cuisine, typically made with:

• Paprika
• Garlic powder
• Onion powder
• Black pepper
• Cayenne pepper
• Oregano
• Thyme

When added to a creamy Alfredo base, it transforms the sauce from mild and buttery to bold, smoky, and slightly spicy, creating a perfect contrast to the richness of the cheese and cream.

You can use store-bought Cajun seasoning or make your own (see recipe below).

Step-by-Step Recipe: How to Make Creamy Cajun Steak Alfredo

Follow these easy steps for a creamy, spicy, steak-loaded pasta.

Step 1: Cook the Pasta

1. Bring a large pot of salted water to a boil.
2. Cook fettuccine according to package instructions until al dente.
3. Reserve ½ cup of pasta water, then drain and set aside.

Step 2: Sear the Steak

1. Pat steak slices dry and season with Cajun seasoning, salt, and pepper.
2. Heat olive oil in a large skillet or Dutch oven over medium-high heat.
3. Add steak in a single layer (work in batches if needed).
4. Sear for 2–3 minutes per side, until browned and cooked to your liking.
5. Remove and set aside.

Tip: Don’t overcrowd the pan—this ensures a good sear.

Step 3: Make the Alfredo Sauce

1. In the same skillet, melt butter over medium heat.
2. Add garlic and sauté for 30 seconds until fragrant.
3. Stir in Cajun seasoning and onion powder.
4. Pour in heavy cream and milk. Bring to a gentle simmer.

7. Simmer for 3–5 minutes until slightly thickened.

Step 4: Combine Everything

1. Add the cooked pasta to the sauce.
2. Toss to coat, adding reserved pasta water 1–2 tbsp at a time if needed to loosen the sauce.
3. Gently fold in the seared steak and any accumulated juices.

Step 5: Serve

1. Divide among plates.
2. Garnish with parsley, extra Parmesan, and a squeeze of lemon.
3. Serve immediately.

Tips for the Best Creamy Cajun Steak Alfredo

• Use Freshly Grated Parmesan – Pre-grated cheese contains anti-caking agents that can make the sauce grainy.
• Don’t Boil the Cream – Simmer gently to prevent curdling.
• Reserve Pasta Water – The starchy water helps the sauce cling to the noodles.
• Slice Steak Thinly – Ensures quick cooking and tender bites.
• Adjust the Heat – Start with 1 tsp Cajun seasoning and add more after tasting.
• Rest the Steak – Let it sit 5 minutes before slicing to retain juices.
