Common Mistakes to Avoid

- Ignoring the sausage quality: Using low-quality sausage can lead to a bland casserole. Opt for fresh, high-quality Italian sausage for the best flavor.

- Skipping seasoning adjustments: Relying solely on the recipe may leave your dish underseasoned. Taste as you go and adjust salt and pepper according to your preference.
- Not letting it cool before serving: Serving immediately after baking can result in a mess. Allow the casserole to cool slightly for better slicing and serving.
- Using a small casserole dish: A dish that’s too small can cause overflow during baking. Use an appropriately sized casserole dish for even cooking.
