Step‑by‑Step Instructions for Cajun Beef Spaghetti
Step 1: Cook Noodles
Bring a large pot of salted water to a rolling boil over medium-high heat. Once boiling, add the spaghetti and cook according to package instructions until al dente, approximately 8-10 minutes depending on the brand. Once done, drain the pasta in a colander, shaking off excess water before setting it aside for later.
Step 2: Prepare Beef
In a medium bowl, toss diced sirloin or ribeye steak with Cajun seasoning until evenly coated. Preheat a large skillet over medium-high heat and melt 2 tablespoons of butter. Once melted, add the seasoned beef to the skillet. Sear for about 4-5 minutes, stirring occasionally, until browned and fully cooked. Remove the beef from the skillet and set aside.
Step 3: Make Sauce
In the same skillet, lower the heat to medium and sauté 2-3 cloves of minced garlic for about 30 seconds until fragrant. Pour in 1 cup of heavy cream, stirring continuously for 1-2 minutes until warmed through. Then, reduce heat to low, adding 4 ounces of cream cheese, 1 cup of mozzarella, and ½ cup of grated Parmesan. Stir until the cheeses melt and the sauce becomes smooth and creamy.
Step 4: Combine
Once the sauce reaches the desired creaminess, return the cooked Cajun-seasoned beef and spaghetti to the skillet. Toss everything together for about 2 minutes, ensuring the spaghetti is well-coated in the creamy three-cheese Parmesan sauce. If the sauce looks too thick, add a splash of pasta water to achieve your preferred consistency.
Step 5: Serve
Plate the Cajun Beef Spaghetti generously, garnishing with freshly chopped parsley for added color and flavor. Optionally, sprinkle extra Parmesan cheese or a dash of Cajun seasoning on top for an extra kick. Serve immediately while hot, allowing everyone to enjoy the comforting richness of this delightful dish.

- Adjust Spice Levels: Feel free to alter Cajun seasoning according to your heat preference; start with less if you’re unsure, and add more later.

- Garnish Thoughtfully: A sprinkle of fresh parsley not only brightens the dish visually but adds a refreshing flavor contrast that enhances the overall experience.
