2 large white onions
2 cups (250 g / 8.8 oz) flour
2 cups (230 g / 8.1 oz) breadcrumbs
Oil for frying (vegetable or canola)
Marinara sauce for dipping
Instructions
Preparation: Carefully slice onions into uniform rings, separating larger and smaller sizes to create nested layers, and cut mozzarella into precise strips that will fit perfectly between onion ring segments.
Layering: Nest smaller onion rings inside larger rings, strategically placing mozzarella strips within the ring gap, potentially using double cheese for enhanced richness.
Chilling: Freeze the prepared rings for one hour to stabilize the cheese and structural integrity, ensuring a solid foundation for subsequent coating.
Coating Station: Set up three distinct stations – seasoned flour, whisked eggs, and crispy breadcrumbs – for a comprehensive breading process.
Breading: Meticulously coat each frozen ring by dusting with flour, thoroughly dipping in egg, and rolling in breadcrumbs, repeating the egg and breadcrumb process for maximum crispiness and robust coverage.
Pre-Frying Chill: Return coated rings to freezer to maintain shape and prevent potential cheese leakage during cooking.
Frying: Heat oil in a deep pot to precisely 350˚F, carefully monitoring temperature, and gently lower rings into hot oil, frying until achieving a golden-brown exterior while preventing complete cheese meltdown.
Finishing: Transfer fried rings onto absorbent paper towels to remove excess oil, then serve immediately alongside zesty marinara sauce for dipping.
