Ingredients

  • Sirloin steak: Choose a well-marbled cut for the juiciest bites Look for bright red color and fine even marbling
  • Olive oil: High quality olive oil gives the steak a great sear and adds depth
  • Butter: Unsalted butter creates a rich base for the sauce Use fresh for the best flavor
  • Garlic: Minced fresh garlic infuses the sauce and steak with irresistible aroma Avoid pre-minced if possible
  • Smoked paprika: Spanish smoked paprika brings a subtle sweetness and smokiness enhancing both steak and sauce
  • Twisted pasta: Rotini or fusilli capture all the creamy sauce and hold up well to the steak
  • Heavy cream: Use real heavy cream for that luscious Alfredo texture Check the date for freshest cream
  • Parmesan cheese: Freshly grated melts smoothly and adds nutty flavor Skip the pre-shredded for best results
  • Cajun seasoning: Look for a blend with balanced heat and no artificial flavors Try making your own for custom heat
  • Salt and pepper: Use kosher salt and fresh cracked black pepper for better control of seasoning
  • Garlic powder: Boosts garlicky flavor in both steak and sauce
  • Red pepper flakes: Completely optional for those who love even more spice
  • Fresh parsley: Chopped parsley brings color and freshness to finish the dish

Step-by-Step Instructions

Cook the Pasta:
Bring a generous pot of salted water to a rapid boil Add your twisted pasta Stir occasionally until cooked al dente about eight to ten minutes Reserve a half cup pasta water before draining This will help create a silky sauce later
Season and Sear the Steak:
Lay your steak cubes out on paper towels and pat them dry Season generously with salt pepper garlic powder and smoked paprika Heat olive oil in a hot skillet once shimmering sear steak cubes in batches just one to two minutes per side until a crust forms inside remains juicy Transfer steak to a plate and keep warm
Create the Garlic Butter Base:
Lower skillet heat to medium Drop in the butter and let it melt completely Add minced garlic immediately Stir constantly and cook just until the garlic becomes golden and fragrant about one to two minutes Take care not to let it burn as this is your sauce's flavor foundation
Prepare the Cajun Alfredo Sauce:
Pour the heavy cream into your garlicky butter Whisk in Cajun seasoning more garlic powder salt and plenty of black pepper Let the mixture gently simmer for three to four minutes until slightly thickened Stir in freshly grated Parmesan cheese until it melts and the sauce turns rich and creamy Smooth lumps here for the silkiest finish
Combine Everything:
Toss drained pasta into the skillet Coat every spiral with the sauce If it feels too thick add reserved pasta water a splash at a time to loosen Gently add in steak bites and any precious juices that have collected Fold everything together just until warm Garnish with parsley and red pepper flakes if desired Serve immediately while the sauce is extra creamy

Twisted pasta is my favorite in this recipe because it really grabs all that creamy sauce My family still talks about the first time we made this together after a long week the aroma of garlic and Cajun spices drew everyone to the kitchen before it even hit the table

Storage Tips

If you have leftovers pack them into an airtight container and refrigerate for up to three days For best texture reheat gently on the stove with a splash of milk or cream The steak stays tender if you avoid microwaving too long If freezing separate steak bites and pasta for easier reheating later

Ingredient Substitutions

No sirloin No problem Try boneless chicken thighs or even a mix of quick sautéed mushrooms for a vegetarian twist Swapping heavy cream for half and half plus a bit of cream cheese lightens the Alfredo without losing richness If you have a favorite homemade Cajun spice blend use it to personalize

Serving Suggestions

This pasta is a meal on its own but a crisp green salad and fresh garlic bread make it feel truly special Leftovers make great next-day lunches Serve with chilled white wine or a fruit-forward red for an elevated dinner at home

Cultural and Historical Context

Cajun Alfredo brings together two classics Southern Cajun seasonings and beloved Italian Alfredo pasta This mashup likely came from home cooks who wanted a spicy creamy sauce The steak bites add a steakhouse feel that makes this meal a crowdpleaser at any table

Ingredients

→ Steak Bites

01 680 g sirloin steak, cut into 2.5 cm cubes
02 30 ml olive oil
03 4 g smoked paprika
04 Salt, to taste
05 Black pepper, to taste
06 Garlic powder, to taste

→ Cajun Alfredo Pasta

07 450 g rotini or fusilli pasta
08 55 g butter
09 4 cloves garlic, minced
10 360 ml heavy cream
11 100 g parmesan cheese, freshly grated
12 16 g cajun seasoning
13 Salt, to taste
14 Black pepper, to taste
15 Garlic powder, to taste

→ Optional Garnishes

16 Red pepper flakes, to taste
17 Fresh parsley, chopped, for garnish

Instructions

Step 01

Bring a large pot of generously salted water to a rolling boil. Add the pasta and cook until al dente, about 8–10 minutes. Reserve 120 ml of the cooking water before draining.

Step 02

Pat the steak cubes dry and season thoroughly with salt, black pepper, garlic powder, and smoked paprika. Heat olive oil in a large skillet over high heat. Sear steak in batches for 1–2 minutes per side, ensuring a deep brown crust. Remove seared steak bites to a plate and set aside.

Step 03

Reduce skillet to medium heat. Add butter and once melted, stir in the minced garlic. Sauté until aromatic, 1–2 minutes, ensuring the garlic does not brown.

Step 04

Pour heavy cream into the skillet with garlic butter. Add cajun seasoning, garlic powder, salt, and black pepper. Simmer gently for 3–4 minutes until slightly thickened. Stir in freshly grated parmesan and mix until fully melted and smooth.

Step 05

Add the drained pasta to the sauce and toss until coated. Adjust sauce consistency with reserved pasta water as needed. Fold in the steak bites along with their juices. Warm through for 1 minute.

Step 06

Garnish with chopped parsley and red pepper flakes if desired. Serve immediately.

Notes

  1. Allow steak to come to room temperature for 20 minutes to maximize tenderness and ensure even cooking.
  2. Gradually add reserved pasta water to achieve a silky, properly emulsified sauce.
  3. Adjust spice intensity by modifying the amount of cajun seasoning and red pepper flakes.
  4. Steak can be cut and seasoned up to 24 hours ahead; pasta can be cooked in advance and dressed with olive oil to prevent sticking.
  5. Substitute chicken or mushrooms for steak as preferred. For a lighter sauce, replace heavy cream with half-and-half blended with cream cheese.
  6. Cast-iron cookware delivers optimal steak searing and enhanced flavor.
  7. Always use freshly grated parmesan for the smoothest sauce texture.
  8. Pair with a green salad and crusty garlic bread. Red wines such as Merlot or oaked Chardonnay complement the dish.
