Ingredients

400g spaghetti
450g diced sirloin or ribeye steak
2 tbsp Cajun seasoning
2 tbsp butter
3 cloves garlic, minced
1 1/2 cups heavy cream
1/2 cup freshly grated Parmesan cheese
1 cup shredded mozzarella cheese
100g cream cheese
1/2 tsp salt
1/2 tsp black pepper
2 tbsp chopped fresh parsley

Instructions

Step 1: Bring a large pot of salted water to a boil and cook the spaghetti until al dente. Drain and set aside.
Step 2: Toss the diced beef with Cajun seasoning. In a hot skillet, melt the butter and sear the beef until browned and cooked through. Remove the beef and set aside.
Step 3: In the same skillet, sauté the minced garlic for about 1 minute until fragrant. Add the heavy cream, cream cheese, mozzarella, and Parmesan cheese. Stir continuously until the sauce is smooth and all the cheese has melted.
Step 4: Return the cooked beef and spaghetti to the skillet. Toss everything together to coat the beef and pasta evenly with the creamy cheese sauce.
Step 5: Sprinkle with chopped fresh parsley and serve hot. Optionally, add extra Parmesan cheese and a dash of Cajun spice for more flavor.

Tips & Variations

Use freshly grated Parmesan for the best flavor and smooth sauce texture.
For a lighter option, replace heavy cream with half-and-half, but the sauce will be less rich.
Add sliced bell peppers or mushrooms when sautéing the garlic for extra vegetables.
Substitute the sirloin or ribeye with chicken breast or turkey for a different protein option.
Feel free to adjust the amount of Cajun seasoning to control the spice level.

Storage

Store leftovers in an airtight container in the refrigerator for up to 3 days. Reheat gently in a saucepan over low heat, adding a splash of cream or milk to loosen the sauce if it thickens too much.

FAQs

Can I use a different type of pasta?

Yes, this recipe works well with fettuccine, penne, or any pasta shape you prefer. Just adjust cooking times according to the pasta package instructions.

How do I prevent the cheese sauce from separating?

Stir the sauce constantly over medium-low heat and avoid boiling once the cheese has melted. Using room temperature cheeses helps them melt more smoothly.
