This creamy cajun steak penne pairs tender sirloin slices with penne and a garlic Parmesan cream sauce that has a gentle Cajun kick.
The steak is seared first for a deep brown crust, then peppers and onion join the same pan so the sauce picks up every browned bit. Plan on about forty minutes from first slice to first bite.

Why This Creamy Cajun Steak Penne Recipe Works
Searing thin steak slices over high heat gives them a browned crust while the centers stay tender and pink.
Peppers and onion bring sweetness that balances the Cajun spice, and the cream mellows the heat into something smooth.
Penne has hollow tubes that fill with sauce, so every bite carries steak, cheese, and seasoning together.
Ingredients for Creamy Cajun Steak Penne
- For the steak: 1 pound sirloin steak thinly sliced, 1 tablespoon olive oil, 1 tablespoon Cajun seasoning, 1 teaspoon smoked paprika, 1 teaspoon garlic powder, and 1/4 teaspoon crushed red pepper flakes.
- For the pasta and vegetables: 12 ounces penne pasta, 1 small diced onion, 1 sliced red bell pepper, and 5 cloves minced garlic.
- For the sauce: 1 cup low sodium beef broth, 1 cup heavy cream, 3/4 cup grated Parmesan cheese, a pinch of black pepper, and parsley.
Sirloin steak. It is lean and affordable, and it turns tender when sliced thin against the grain.
Cajun seasoning. This blend adds paprika, garlic, and pepper in one spoonful, so the steak is seasoned with little effort.
Red bell pepper. The sweet crunch softens in the pan and adds color to the pasta.
Beef broth. It deglazes the pan and builds a savory base under the cream.
Parmesan cheese. Grate it fresh so it melts smoothly and does not clump.

Tips and Variations for Creamy Cajun Steak Penne
Slice against the grain. Cut across the muscle fibers so each strip chews easily.
Freeze briefly. Chill the steak in the freezer for twenty minutes before slicing to get thin, even strips.
Sear in batches. Crowding the pan steams the steak, so cook it in two rounds if needed.
Control the heat. Reduce the Cajun seasoning for a mild plate or add extra red pepper flakes for more fire.
Add mushrooms. Sliced mushrooms cook well with the peppers and add an earthy note.
Flag the allergens. This dish contains milk and wheat, and the pasta may include egg, so check labels.
Check the doneness. Cook sliced steak to 145 degrees F and let it rest briefly. Wash hands and tools after handling raw meat.
Check trusted guidance. See the Texas AgriLife Extension food safety guide for temperature charts.
