Before you start
Before starting, ensure that all ingredients are measured and ready to go, as the cooking process moves quickly once the pasta is boiling. Mince the garlic finely to ensure it distributes evenly throughout the sauce without creating large, bitter chunks.
Shred the mozzarella cheese if it is not already pre-shredded, and chop the fresh parsley. Having everything prepped in advance allows you to focus on the cooking steps and ensures the timing remains consistent, resulting in perfectly cooked pasta and a well-emulsified, silky sauce.

Instructions
Boiling the spaghetti
- Boil the pastaBring a large pot of salted water to a rolling boil. Add the spaghetti and cook according to the package instructions until al dente. Drain the pasta in a colander, reserving about half a cup of the starchy pasta water for the sauce.Look for The pasta should be firm to the bite but cooked through.Tip Adding salt to the boiling water ensures the pasta is seasoned from within.
The spaghetti should be cooked in a large pot of salted water until it reaches an al dente texture. It is vital to drain the pasta properly while reserving some of the starchy water. This water is the secret to a professional-quality sauce, so do not skip this step. Test a strand of pasta to ensure it is tender but still offers a slight resistance to the bite before draining.
Browning the beef
- Cook the beefIn a large skillet over medium-high heat, brown the ground beef until no pink remains. Use a wooden spoon to break the meat into small crumbles as it cooks. Ensure the internal temperature reaches 160°F (71°C) to verify it is cooked through. Drain any excess fat if necessary.Look for The meat will appear browned and crumbly with no visible pink.Safe temperature 160°F (71°C) internal temperature (ground meat)Tip Do not crowd the skillet, as this helps the beef brown instead of steaming.
The ground beef should be browned thoroughly in the skillet until it is deep in color and fully cooked through. Use a sturdy spoon to break up any large clumps, ensuring the meat is evenly sized for consistent cooking. The skillet will sound like it is sizzling, and the aroma of the browning beef should be savory and inviting. Check that no pink remains before proceeding to the next stage.
Finishing the sauce
- Create the sauce and assembleAdd the butter and minced garlic to the skillet with the cooked beef. Sauté for one minute until the garlic is fragrant. Stir in the Cajun seasoning and the cooked spaghetti. Add a splash of the reserved pasta water to loosen the sauce. Top with shredded mozzarella, then cover briefly to melt. Garnish with chopped parsley and red chili flakes before serving immediately.Look for The cheese will be melted and gooey, and the sauce will coat the pasta evenly.Tip The residual heat from the pasta and beef is usually enough to melt the cheese perfectly.
After adding the butter, garlic, and spices, the sauce should smell intensely fragrant. Once the pasta and cheese are incorporated, the mixture should look glossy and cohesive.
The cheese should be perfectly melted and stringy, creating a beautiful pull when lifted. The final dish should be hot, well-coated in the garlic butter sauce, and visually appealing with the garnish of parsley and chili flakes.
Common mistakes
A common mistake is overcooking the pasta, which can lead to a mushy texture; always aim for al dente. Another error is neglecting to reserve the pasta water, which is crucial for creating the creamy sauce consistency.
Adding too much liquid at once can result in a thin, watery sauce, so add the water gradually. Finally, ensure the heat is not too high when adding the cheese, as this can cause the dairy to separate or become stringy instead of creamy.
How to tell it’s done
The dish is done when the ground beef is fully browned and has reached an internal temperature of 160°F (71°C), and the spaghetti is tender yet firm.
The most important indicator of doneness is the state of the sauce: it should be glossy, creamy, and clinging to the noodles rather than pooling at the bottom of the pan. The cheese should be completely melted and stringy when pulled with tongs, indicating the dish is ready for serving.
- Ground meat: 160°F (71°C) in the thickest part
