Before you start
Before beginning, ensure all ingredients are measured and ready, as the cooking process moves quickly once the beef is in the skillet. Have your baking dish nearby and preheat the oven early to ensure it is at the correct temperature when the pasta is ready to be assembled.
Grating your own cheddar cheese from a block rather than using pre-shredded varieties will result in a much better melt and a smoother, more cohesive cheese pull.

- 1 lb ground beef
- 1 lb spaghetti
- 2 tbsp Cajun seasoning
- 24 oz tomato sauce
- 2 cups cheddar cheese, shredded
Instructions
Browning and Simmering the Sauce
- Prepare the meat and sauceHeat a large skillet over medium-high heat. Add the ground beef and cook, breaking it apart with a spatula, until browned and no longer pink. Drain excess fat if necessary. Stir in the Cajun seasoning and tomato sauce, simmering for 10 minutes to allow flavors to meld. Ensure the internal temperature of the beef reaches 160°F (71°C).Look for The sauce should be bubbling gently and the meat should be fully cooked through.Safe temperature 160°F (71°C) internal temperature (ground meat)Tip Adding the seasoning directly to the meat before the sauce helps to toast the spices and release their full aroma.
The meat should be deeply browned and fragrant, with the spices fully integrated into the sauce. The mixture should have reduced into a thick, cohesive consistency that coats the back of a spoon, signaling that the flavors have concentrated properly before the pasta is introduced.
Combining and Preparing for the Oven
- Cook and combine pastaBring a large pot of salted water to a boil. Cook the spaghetti according to the package instructions until al dente. Drain the pasta using a colander, then return it to the pot. Pour the prepared Cajun meat sauce over the cooked spaghetti and toss thoroughly until every strand is coated.Look for The pasta should be firm to the bite and evenly coated with the thick, glossy meat sauce.Tip Reserve a small amount of pasta water to adjust the consistency of the sauce if it appears too thick after combining.
The spaghetti should be evenly coated with the meat sauce, appearing glossy and uniform in color.
Ensure there are no dry patches of pasta, and verify that the ratio of sauce to noodles is balanced, providing a generous coating that will maintain its moisture during the baking phase.
Final Baking and Melting
- Bake and servePreheat your oven to 375°F (190°C). Transfer the spaghetti mixture into a baking dish, spreading it out evenly. Sprinkle the shredded cheddar cheese over the top. Place in the oven for 10 to 15 minutes, or until the cheese is melted and bubbling. Serve immediately while hot to ensure the best cheese pull.Look for The cheese should be completely melted, golden in spots, and pulling away from the sides of the dish.Tip Avoid overbaking, as this can cause the cheese to separate or the pasta to become too soft.
The cheese should be completely melted and starting to brown slightly at the edges. When lifted with tongs, the cheese should form long, stretchy strands, and the entire dish should be hot and bubbling throughout, indicating it is ready to be removed from the oven.
Common mistakes
A common mistake is overcooking the pasta before it hits the oven, which can result in mushy noodles. Always aim for al dente, as the residual heat from the sauce and the oven will finish the cooking process.
Another error is using too much liquid in the sauce, which makes the final dish soupy; stick to the recommended amount of tomato sauce and allow it to simmer down properly before adding the pasta to the skillet.
How to tell it’s done
The dish is considered done when the cheese is fully melted, bubbling, and has reached a golden brown color in several spots. The internal temperature of the ground beef must reach 160°F (71°C) to ensure safety.
The sauce should be thick and clinging to the pasta, with no excess liquid pooled at the bottom of the baking dish. If the center is not hot, continue baking for an additional few minutes until it is heated through.
