Professional Tips & Techniques

- Cheese blend: Using a combination of mozzarella and Parmesan cheese creates a richer, more complex flavor.
- Doneness cues: Look for a bubbly, golden-brown cheese topping as a sign that the casserole is done.
- Avoid common mistakes: Don’t overcook the spaghetti before baking, as it will continue to cook in the oven. Also, ensure the meat is fully browned to avoid a greasy finish.
