Ingredients
(Tip: You can find the complete list of ingredients and their measurements in the recipe card below.)
Spaghetti
Spaghetti forms the backbone of the casserole. Its long strands hold the sauce well and bake evenly without becoming mushy.
Ground Beef
Ground beef provides savory depth and structure. When properly browned, it adds richness without excess grease.
Butter
Butter builds the base of the sauce and contributes a smooth, rounded mouthfeel.
Garlic
Garlic adds aromatic intensity and balances the richness of the dairy components.
All-Purpose Flour
Flour thickens the sauce, ensuring the casserole sets properly once baked.
Milk
Milk creates a creamy foundation. Whole milk works best for body and flavor.
Cheddar Cheese
Cheddar delivers the signature sharpness. I prefer a medium to sharp cheddar for balanced flavor.
Cream Cheese
Cream cheese enhances creaminess and gives the casserole a smooth, cohesive texture.
Italian Seasoning
Italian seasoning adds herbal notes that complement both the pasta and cheese.
Salt
Salt enhances all the individual flavors and should be adjusted carefully.
Black Pepper
Black pepper provides subtle warmth and contrast to the richness.
Parsley
Parsley adds freshness and visual contrast when sprinkled on top after baking.
Directions
Begin by preheating the oven to 190°C and lightly greasing a large baking dish. Cook the spaghetti in well-salted water until just al dente, then drain and set aside.
In a large skillet over medium heat, brown the ground beef until fully cooked. Remove excess fat and set the beef aside. In the same skillet, melt the butter and sauté the garlic briefly until fragrant. Whisk in the flour and cook for one minute to remove the raw taste.
Gradually add the milk, whisking constantly to form a smooth sauce. Once thickened, lower the heat and stir in the cream cheese until fully melted. Add the cheddar cheese and stir until smooth. Season with Italian seasoning, salt, and black pepper.
Combine the cooked spaghetti, ground beef, and cheese sauce in a large bowl, mixing until evenly coated. Transfer the mixture to the prepared baking dish and spread evenly.
Bake uncovered for 25 to 30 minutes, until bubbling and lightly golden on top. Allow the casserole to rest for 10 minutes before serving.

Store leftovers in an airtight container in the refrigerator for up to three days. Reheat in the oven at 175°C, covered, until warmed through. Individual portions can be reheated gently on the stovetop with a splash of milk.
Variations and Customizations
This casserole is highly adaptable and can be adjusted to suit a wide range of preferences. Ground chicken or turkey can replace the beef for a lighter option. For added richness, mix in a small amount of sour cream with the sauce.
Vegetables such as spinach, sautéed mushrooms, or steamed broccoli can be incorporated to add texture and nutritional balance. If you prefer a sharper flavor, increase the ratio of cheddar or use an extra-sharp variety. I tested this with a blend of white and yellow cheddar, and the result was both visually appealing and more complex in taste.
For a slightly crispy topping, sprinkle additional shredded cheddar on top during the final 10 minutes of baking. You can also add a light breadcrumb topping mixed with melted butter for added texture.
