8. Serve & Enjoy

Pro Tips for the Best Mozzarella-Stuffed Onion Rings
- Use Firm Mozzarella – Avoid fresh mozzarella, as it contains too much moisture and can leak out.
- Freeze the Rings Completely – This prevents the cheese from melting too fast during frying.
- Double Bread for Extra Crunch – A second coating of eggs and breadcrumbs creates a thicker, crispier shell.
- Fry in Batches – Avoid overcrowding the pan to ensure even frying.
- Use a Thermometer – Keep oil at 350°F (175°C) to prevent sogginess.
