Prep Onion & Cheese Rings:
Choose large onion rings and insert mozzarella stick pieces into the center of each, trimming cheese as needed to fit snugly inside.

Freeze Rings:
Place prepared cheese-filled onion rings on a baking sheet and freeze for at least 1 hour to firm up.

Prepare Breading Station:
Place flour in one bowl. In a second bowl, whisk eggs with milk. In a third bowl, combine breadcrumbs, garlic powder, Italian seasoning, salt, and pepper.

Coat Rings:
Dip each frozen ring into flour, then egg mixture, then breadcrumbs. For extra crunch, dip again in egg and breadcrumbs.

Fry:
Heat oil in a deep pan to 350°F (175°C). Fry onion rings in batches for 2–3 minutes or until golden brown. Drain on paper towels.

Serve:
Serve hot with marinara sauce, ranch, or your favorite dip!
