Ingredients
- Sirloin steak cut into cubes: This cut stays juicy and tender The marbling adds flavor to every piece
- Butter: This is the heart of both the steak bites and the Alfredo Choose unsalted for better control
- Fresh garlic minced: It brings those punches of aroma and sharpness
- Cajun seasoning: Lends heat and savory depth in every bite Look for a balanced blend without too much salt
- Smoked paprika: Gives warm smoky notes Opt for Spanish for richness
- Black pepper: Freshly ground is best
- Salt: Taste while you season It makes the flavors pop
- Olive oil: Helps the steak sear for those crusty edges Use extra virgin for best flavor
- Pasta twists like rotini or fusilli: Their shape hugs up all the Alfredo goodness Choose bronze-cut if you can for more texture
- Heavy cream: This gives the Alfredo its silkiness Go for full-fat to avoid a watery sauce
- Parmesan cheese: Only freshly grated will create that classic sharp cheesy flavor
- Mozzarella cheese: Melts into the sauce for sultry stretchiness Pick whole milk version
- Milk (optional): To thin the Alfredo As needed
Each ingredient plays a part
Each ingredient plays a part in creating layers of flavor and a pleasing contrast of textures. I always splurge a little on good steak and real Parmesan to make this extra comforting.
Step-by-Step Instructions
- Marinate the Steak:
- Toss the sirloin cubes in a bowl with Cajun seasoning smoked paprika salt and black pepper. Let the flavors soak in for at least ten minutes to infuse every bite.
- Sear the Steak:
- Heat olive oil and part of the butter over medium-high in a skillet. Arrange steak pieces in a single layer do not overcrowd. Sear undisturbed for a full four to five minutes per side for a deep golden crust This is where the flavor magic happens. Work in batches if needed.
- Make the Garlic Butter:
- Use the same pan for all those browned bits. Melt the rest of the butter on medium. Add minced garlic and stir for about one minute until just fragrant not browned.
- Combine Steak and Butter:
- Return the seared steak to the pan. Turn all the pieces gently so they soak up the garlicky butter. Take off the heat as soon as the steak is coated.
- Boil the Pasta:
- Cook your pasta twists as the package says Make sure the water is well salted This creates the foundation for your sauce. Drain when al dente and do not rinse.
- Make the Alfredo Sauce:
- In a separate pan melt butter on medium. Add the rest of your garlic and sauté until fragrant. Pour in heavy cream and let it gently simmer. Gradually stir in Parmesan and mozzarella cheeses until smooth and stretchy. Taste and season with salt and pepper. If the sauce is thicker than you like splash in a little milk.
- Toss Pasta with Alfredo:
- Add the drained pasta directly into the Alfredo sauce pan. Toss with care so all the pasta is coated with that dreamy sauce.
- Plate and Serve:
- Spoon creamy pasta onto each plate. Top with sizzling steak bites and plenty of pan juices.

Parmesan is the soul ingredient for me in Alfredo My best food memory is my daughter helping grate cheese and sneaking bites before anything hit the sauce This dish is always a playful family affair.
Storage Tips
Leftovers keep well in an airtight container in the fridge for up to three days I suggest storing steak bites and pasta separately for best texture To reheat gently warm the Alfredo pasta with a splash of milk over low heat and briefly rewarm steak in a skillet with a touch of butter to prevent dryness
Ingredient Substitutions
You can swap sirloin for ribeye or New York strip if you prefer more marbling For a lighter version use half and half instead of heavy cream If you need a vegetarian take skip the steak and add sautéed mushrooms or broccoli for an ultra-luxurious veggie Alfredo
Serving Suggestions
Serve with a crisp green salad and garlic bread for a classic combination Roasted vegetables like asparagus or brussels sprouts go beautifully alongside You can even pile everything into a large platter family-style and let everyone help themselves

Recipe Roots
