Ingredients
For the Cajun Steak
-
1 pound (450g) sirloin steak or ribeye
-
1 tablespoon Cajun seasoning (adjust to taste)
-
1 teaspoon smoked paprika
-
1 teaspoon garlic powder
-
1 teaspoon onion powder
-
1 tablespoon olive oil
-
Salt & freshly ground black pepper, to taste
For the Alfredo Sauce
-
2 tablespoons butter
-
4 cloves garlic, minced
-
2 cups heavy cream
-
1 cup freshly grated Parmesan cheese
-
1 teaspoon Cajun seasoning (optional for extra heat)
-
Salt & pepper, to taste
For the Pasta
-
12 ounces (340g) fettuccine pasta (or pasta of choice)
-
1 tablespoon salt (for boiling water)
Optional Garnishes
-
Fresh parsley, chopped
-
Extra Parmesan cheese
-
Red pepper flakes (for extra spice)
Step-by-Step Instructions
Step 1 – Prepare the Pasta
-
Fill a large pot with water, add 1 tablespoon of salt, and bring it to a boil.
-
Add the fettuccine pasta and cook according to the package instructions until al dente.
-
Reserve 1 cup of pasta water for later use, then drain and set aside.
Pro Tip: Adding salt to the water seasons the pasta from within, enhancing the flavor of the entire dish.
Step 2 – Season the Steak
-
Pat the steak dry with paper towels to remove excess moisture—this helps create a perfect sear.
-
In a small bowl, combine Cajun seasoning, smoked paprika, garlic powder, onion powder, salt, and pepper.
-
Rub the spice mix all over the steak until evenly coated.
Step 3 – Cook the Steak
-
Heat a large skillet or cast-iron pan over medium-high heat and add 1 tablespoon olive oil.
-
Once the oil is shimmering, place the steak in the pan and sear for 3–4 minutes per side for medium-rare (adjust cooking time to your preferred doneness).
-
Remove the steak from the pan and let it rest for 5 minutes before slicing it into thin strips against the grain.
Pro Tip: Resting the steak prevents the juices from running out, keeping it juicy and flavorful.
Step 4 – Make the Creamy Cajun Alfredo Sauce
-
In the same skillet (don’t wipe it clean—you want those steak drippings), melt 2 tablespoons butter over medium heat.
-
Add minced garlic and sauté for about 1 minute until fragrant.
-
Pour in the heavy cream, stirring to combine with the garlic and drippings.
-
Bring the mixture to a gentle simmer, then stir in the Parmesan cheese until melted and smooth.
-
Season with Cajun seasoning, salt, and pepper.
-
If the sauce feels too thick, add a splash of reserved pasta water until you reach your desired consistency.
Step 5 – Combine and Serve
-
Add the cooked pasta to the sauce, tossing until every strand is coated in the creamy goodness.
-
Arrange the sliced steak on top or toss it into the pasta for a more rustic presentation.
-
Garnish with fresh parsley, extra Parmesan, and red pepper flakes if desired.

Cooking Tips & Tricks
-
Choose the Right Cut of Steak – Sirloin is lean and affordable, while ribeye offers extra marbling for more flavor.
-
Don’t Overcook the Pasta – Since it will sit in the hot sauce for a bit, keep it slightly under al dente before mixing.
-
Fresh Parmesan is Key – Pre-grated cheese often contains anti-caking agents that prevent smooth melting.
-
Adjust the Cajun Kick – Add more seasoning for spice lovers, or tone it down for a milder flavor.
-
Make it Ahead – You can cook the steak in advance, then reheat it briefly in the sauce before serving.
Variations
-
Shrimp Version – Swap steak for Cajun-seasoned shrimp for a lighter, seafood-inspired dish.
-
Vegetable Boost – Add sautéed bell peppers, mushrooms, or spinach to the sauce.
-
Low-Carb Option – Use zucchini noodles or spaghetti squash instead of pasta.
-
Cheesy Upgrade – Stir in a handful of mozzarella for extra cheesiness.
Serving Suggestions
-
With Garlic Bread – Perfect for mopping up that luscious sauce.
-
With a Crisp Side Salad – A fresh green salad balances the richness.
-
With Roasted Veggies – Oven-roasted asparagus, carrots, or Brussels sprouts pair beautifully.
Storing & Reheating
-
Refrigerator: Store leftovers in an airtight container for up to 3 days.
-
Freezer: Freeze portions in airtight containers for up to 2 months (best to freeze without pasta for better texture).
-
Reheat: Warm on the stove over low heat, adding a splash of cream or milk to restore creaminess.
