Directions for Cheesy Stuffed Mozzarella Onion Rings
Let’s create these irresistible Cheesy Stuffed Mozzarella Onion Rings!
Prepare Onions
I peel 2 large white onions and slice them into ½-inch (1 cm) rings, carefully separating them to keep intact. I select pairs of larger and smaller rings to fit together.
Slice Mozzarella
I cut 3 slices of mozzarella into ½-inch strips (or use string cheese). I ensure enough strips to fill the gaps between onion rings, aiming for a snug fit.
Assemble Rings
I place a smaller onion ring inside a larger one and fill the gap with mozzarella strips, pressing gently to secure. For extra cheesiness, I layer two strips. I repeat with remaining rings and freeze them on a tray for 1 hour to set.
Set Up Coating Stations
I prepare three bowls: one with 2 cups flour, one with 5 beaten eggs, and one with 2 cups breadcrumbs, arranging them for easy dipping.
Coat Rings
I coat each frozen ring in flour, shaking off excess, then dip in egg, followed by breadcrumbs. For extra crunch, I dip back in egg and breadcrumbs again. I place coated rings back in the freezer for 30 minutes to firm up.
Heat Oil
In a large pot, I heat 4 cups vegetable oil over medium-high heat to 350°F (175°C), using a thermometer to confirm the temperature.
Fry Rings
I fry 2–3 rings at a time in the hot oil for 2–3 minutes per side until golden brown, ensuring the cheese doesn’t ooze out. I avoid overcrowding to maintain oil temperature.
Drain and Serve
I remove the rings with a slotted spoon, drain on a paper towel-lined plate, and serve hot with 1 cup marinara sauce for dipping.

Storage
I store Cheesy Stuffed Mozzarella Onion Rings in an airtight container in the refrigerator for up to 3 days after cooling completely. To freeze, I freeze assembled, uncooked rings on a baking sheet, then transfer to a freezer-safe bag for up to 2 months; fry directly from frozen, adding 1–2 minutes to cooking time. To reheat refrigerated rings, I bake at 375°F (190°C) for 10 minutes to restore crispiness, avoiding the microwave to prevent sogginess.
FAQs About Cheesy Stuffed Mozzarella Onion Rings
Here are answers to some common questions about this recipe:
Can I use a different cheese instead of mozzarella?
Yes, you can use cheeses like cheddar, pepper jack, or gouda. Ensure they melt well and cut them into strips to fit snugly between the onion rings.
Can I make these onion rings gluten-free?
Yes, substitute all-purpose flour and breadcrumbs with gluten-free versions. Check that other ingredients, like marinara sauce, are gluten-free to maintain dietary needs.
