1-First Steps: Slice the onions into rings about ½ inch wide and the mozzarella cheese into ½ inch wide slices. Pair the onion rings so the cheese slices fit tightly between them, then push the cheese into the rings to completely fill the gap. Dredge the assembled onion and cheese rings with the ½ cup of flour and freeze for at least 45 minutes overnight works best to keep everything in place.

2-Slice onions into 1/2-inch rings and separate them gently.

3-Prepare the mozzarella by cutting it into strips to fit inside the rings.

4-Coat the assembled rings in flour, then dip into the 2 beaten eggs.

5-Roll them in 1 cup of plain breadcrumbs for that crispy finish.

6-Freeze the rings to set the coating and prevent cheese from leaking.

7-Cooking and Serving: Once frozen, heat peanut or canola oil to about 350°F and fry the rings in batches for 2-3 minutes until golden brown. Drain on paper towels and serve hot with the ½ cup of marinara sauce.
