Tips & Substitutions

To enhance flavor, consider adding sautéed vegetables like bell peppers or mushrooms to the mixture. For a twist, substitute pepperoni with cooked Italian sausage or diced ham. Ensure the spaghetti is al dente to prevent it from becoming mushy during baking. If you prefer a crispier top, broil for a few minutes after baking. This dish can also be enjoyed with a side of garlic bread.
