Step‑by‑Step Instructions for Cajun Beef Spaghetti in Creamy Three-Cheese Parmesan Sauce
Step 1: Boil and Cook Spaghetti
Start by bringing a large pot of salted water to a rolling boil over high heat. Once boiling, add the spaghetti and cook according to package instructions until al dente, about 8 to 10 minutes. Once cooked, drain the pasta well in a colander and set it aside, reserving a bit of pasta water in case you need to thin the sauce later.
Step 2: Prepare and Sear the Beef
While the pasta cooks, toss the diced beef with Cajun seasoning in a mixing bowl until evenly coated. Heat a large skillet over medium-high heat and add a tablespoon of butter. Once the butter is melted and bubbling, add the seasoned beef. Sear the beef for about 3–4 minutes, stirring occasionally until nicely browned and just cooked through. Remove the beef from the skillet and set it aside.
Step 3: Sauté Garlic
In the same skillet, add another tablespoon of butter and decrease the heat to medium. Toss in the freshly minced garlic and sauté for about 1 minute, or until fragrant, ensuring it doesn’t burn. This step will create a wonderful aroma in your kitchen and lay the foundation for the creamy sauce in your Cajun Beef Spaghetti.
Step 4: Make the Creamy Sauce
Pour in the heavy cream, stirring continuously, and bring it to a gentle simmer. Next, add the cream cheese, mozzarella, and Parmesan, stirring until melted and smooth, about 3–5 minutes. The sauce should begin to bubble gently, becoming creamy and luscious, perfectly ready to envelop your pasta and beef.
Step 5: Combine Beef and Pasta
Reduce the heat to low and return the cooked beef and spaghetti to the skillet with the creamy sauce. Toss everything together thoroughly, ensuring the spaghetti and beef are well-coated in the delightful sauce. If the mixture appears too thick, add a splash of reserved pasta water to achieve your desired consistency.
Step 6: Garnish and Serve
Once everything is thoroughly mixed, remove the skillet from the heat. Plate the Cajun Beef Spaghetti in Creamy Three-Cheese Parmesan Sauce in shallow bowls and garnish generously with chopped parsley for freshness. Optionally, offer extra Parmesan and a sprinkle of Cajun seasoning on the side for those who desire an extra kick before diving in!

Expert Tips for Cajun Beef Spaghetti
• Grate Fresh Cheese: Using freshly grated cheese ensures a smoother melt and a more flavorful sauce. Avoid pre-packaged cheese as it may contain anti-caking agents.
