Ingredients for Spicy Cajun Steak & Mozzarella Alfredo Pasta

  • 8 oz penne pasta (or any pasta of choice)
  • 2 ribeye or sirloin steaks (room temperature)
  • 2 tbsp Cajun seasoning (divided)
  • Salt & black pepper to taste
  • 2 tbsp olive oil
  • 2 tbsp butter
  • 3 cloves garlic (minced)
  • 1 cup heavy cream
  • 1/2 cup grated parmesan cheese
  • 1 1/4 cup shredded mozzarella cheese
  • 1/4 tsp smoked paprika
  • 1/2 tsp crushed red pepper flakes (optional, for heat)
  • Fresh parsley (chopped, for garnish)

Step 1: Cook the Pasta

Bring a large pot of salted water to a boil. Add the penne pasta and cook according to package instructions until al dente. Drain and set aside, reserving ½ cup of the pasta water.


Step 2: Season and Sear the Steak

Pat the steaks dry with paper towels. Rub both sides with 1 tablespoon of Cajun seasoning, salt, and black pepper. Heat olive oil in a cast-iron skillet or heavy pan over medium-high heat. Once hot, sear the steaks for about 3-4 minutes per side (for medium-rare), or until desired doneness. Transfer steaks to a plate and let them rest.


Step 3: Make the Alfredo Sauce

In the same pan, lower the heat to medium. Add butter and minced garlic. Sauté for about 1 minute until fragrant. Pour in the heavy cream and stir in the remaining Cajun seasoning, paprika, and crushed red pepper flakes (if using). Let it simmer gently for 2-3 minutes.


Step 4: Add Cheese and Pasta

Reduce heat to low and stir in the parmesan and mozzarella cheeses until fully melted and smooth. If the sauce is too thick, add a splash of reserved pasta water until it reaches your desired consistency. Fold in the cooked penne pasta and toss to coat.


Step 5: Slice and Serve the Steak

Slice the rested steak into strips. Plate the creamy pasta and arrange the steak slices over the top. Spoon over any leftover sauce from the pan. Garnish with fresh chopped parsley for a vibrant touch.


Storage Instructions

Leftovers of this Spicy Cajun Steak & Mozzarella Alfredo Pasta can be just as delicious the next day with proper storage. Allow the pasta and steak to cool to room temperature before storing.

  • Refrigerator: Store in an airtight container for up to 3 days. To reheat, add a splash of milk or cream and warm gently over the stove or in the microwave to bring the sauce back to life.
  • Freezer: You can freeze the pasta without the steak for up to 2 months. When ready to eat, thaw overnight in the fridge and reheat on the stovetop. It’s best to cook fresh steak if freezing the pasta.

Frequently Asked Questions

1. Can I use a different cut of steak?

Yes, sirloin, strip steak, or filet mignon all work well. Just make sure it’s a tender cut for best results.

4. Can I make this dish vegetarian?

Absolutely! Skip the steak and use sautéed mushrooms, tofu, or roasted veggies instead.

7. What’s a good side dish for this pasta?
