Ingredients

- 2 large ribeye or sirloin steaks (about 1–1.5 lbs total)
- 1 tablespoon Cajun seasoning
- 1 teaspoon smoked paprika
- 1 teaspoon garlic powder
- ½ teaspoon black pepper
- 1 tablespoon olive oil
- 1 tablespoon butter
For the Pasta
- 12 oz penne pasta
- 1 tablespoon salt (for pasta water)
For the Cajun Cheese Sauce
- 2 tablespoons butter
- 3 cloves garlic, minced
- 1 small onion, finely diced
- 1 red bell pepper, sliced
- 1 teaspoon Cajun seasoning
- 1 teaspoon smoked paprika
- ½ teaspoon chili flakes (optional for extra heat)
- 2 tablespoons all-purpose flour
- 2 cups heavy cream
- 1 cup whole milk
- 1½ cups shredded cheddar cheese
- ½ cup shredded mozzarella cheese
- ¼ cup grated parmesan cheese
- Salt and pepper to taste
Optional Garnish
- Fresh parsley
- Extra parmesan
- Red pepper flakes
- Chopped green onions
Equipment Needed
- Large pot for pasta
- Cast iron skillet or heavy pan
- Saucepan
- Tongs
- Whisk
- Sharp knife
- Cutting board
Step 1: Preparing the Steak
Take the steaks out of the refrigerator 30 minutes before cooking to allow them to come to room temperature. This helps them cook evenly.
Pat the steaks dry using paper towels. Removing excess moisture ensures a beautiful crust during searing.
Season both sides generously with:
- Cajun seasoning
- Smoked paprika
- Garlic powder
- Black pepper
Press the seasoning gently into the meat.
Step 2: Cooking the Steak
Heat a cast iron skillet over medium-high heat until very hot.
Add olive oil to the pan.
Place the steak in the pan and sear for:
- 3–4 minutes on the first side
- 3–4 minutes on the second side
Add butter during the final minute and spoon the melted butter over the steak.
Cook until the internal temperature reaches:
- 130°F for medium-rare
- 140°F for medium
Remove from the pan and allow the steak to rest for 10 minutes before slicing.
Resting keeps the juices inside the meat.
Step 3: Cooking the Pasta
Bring a large pot of salted water to a rolling boil.
Add the penne pasta and cook according to package instructions until al dente, usually 9–11 minutes.
Reserve ½ cup of pasta water, then drain the pasta and set aside.
The pasta water can help adjust the sauce consistency later.
Step 4: Preparing the Cajun Cheese Sauce
In a large saucepan or skillet, melt butter over medium heat.
Add:
- diced onion
- sliced red bell pepper
Cook for 4–5 minutes until softened.
Add minced garlic and cook for 30 seconds until fragrant.
Step 5: Building the Flavor Base
Sprinkle in:
- Cajun seasoning
- smoked paprika
- chili flakes
Stir well to coat the vegetables.
Cook for 1 minute to toast the spices and release their flavor.
Step 6: Creating the Roux
Sprinkle flour into the pan.
Whisk continuously for about 1 minute to cook out the raw flour taste.
The mixture should form a thick paste that coats the vegetables.
Step 7: Making the Cream Sauce
Slowly pour in the heavy cream while whisking constantly.
Then add the milk.
Continue whisking until smooth and lump-free.
Bring the mixture to a gentle simmer and cook for 3–4 minutes until slightly thickened.
Step 8: Adding the Cheese
Reduce heat to low.
Gradually add:
- shredded cheddar
- mozzarella
- parmesan
Stir continuously until the cheese melts completely and the sauce becomes smooth and creamy.
Taste and adjust seasoning with salt and pepper.
Step 9: Combining Pasta and Sauce
Add the cooked penne pasta to the sauce.
Toss gently until the pasta is completely coated.
If the sauce becomes too thick, add a splash of the reserved pasta water.
Step 10: Slicing the Steak
Slice the rested steak against the grain into thin strips.
Cutting against the grain ensures the steak remains tender.
Step 11: Assembling the Dish
Divide the creamy Cajun pasta among serving bowls.
Top each bowl with slices of steak.
Garnish with:
- chopped parsley
- extra parmesan
- green onions
- red pepper flakes
Serve immediately while hot and creamy.
