-
Heat 1 tbsp olive oil in a large skillet over medium‑high heat.
-
Add steak in a single layer (work in batches if needed) and sear 2–3 minutes per side until browned and cooked to your liking.
-
Transfer steak to a plate and tent loosely with foil.
Step 4: Sear the Shrimp
-
In the same skillet, add remaining 1 tbsp olive oil and 1 tbsp butter.
-
When hot and foamy, add shrimp in a single layer.
-
Cook 1–2 minutes per side until just pink and opaque.
-
Squeeze a little lemon juice over the shrimp if you like, then remove to a plate with the steak.
Step 5: Make the Cajun Alfredo Sauce
-
Lower heat to medium. In the same skillet, melt 3 tbsp butter.
-
Add garlic and sauté about 30 seconds until fragrant (do not brown).
-
Pour in heavy cream, scraping up any browned bits from the pan.
-
Simmer gently 3–4 minutes, stirring, until slightly thickened.
-
Whisk in Parmesan, a handful at a time, until smooth.
-
Season with 1/2 tsp Cajun seasoning, salt, and pepper. Add more Cajun seasoning if you want extra heat.
If the sauce becomes too thick, thin it with a splash of reserved pasta water or milk.
Step 6: Combine With Pasta
-
Add cooked pasta directly to the skillet with the Alfredo sauce.
-
Toss with tongs until every strand is coated, adding a little pasta water if needed for a silky consistency.
Step 7: Serve
-
Divide the creamy Cajun Alfredo pasta among plates or bowls.
-
Top each portion with seared steak and shrimp.
-
Spoon a bit of extra sauce over the top.
-
Finish with chopped parsley and a final grind of black pepper.
Tips and Variations
-
Use half‑and‑half instead of heavy cream for a lighter sauce (it will be slightly thinner).
-
Add sautéed bell peppers or mushrooms to the skillet before the sauce for more veggies and flavor.
-
Adjust spice: use mild Cajun seasoning for subtle heat, or add cayenne or hot sauce if you like it fiery.
This Cajun Shrimp and Steak Alfredo Pasta brings together bold Southern spice and cozy Italian‑style creaminess—perfect for date night, special occasions, or whenever a plain bowl of pasta just won’t do.
