Ingredients
(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)
Main:
1 large onion, sliced into 1/2-inch thick rings
8 mozzarella cheese sticks, cut in half crosswise
For the coating:
1 cup all-purpose flour
2 large eggs
2 tablespoons milk
1 1/2 cups panko breadcrumbs
1 cup regular breadcrumbs
1 teaspoon garlic powder
1 teaspoon paprika
1/2 teaspoon salt
1/2 teaspoon black pepper
For frying:
3 cups vegetable oil
Directions
Peel the onion and slice it into thick 1/2-inch rings. Separate the rings and match similar-sized pairs together.
Cut each mozzarella stick in half. Place a piece of mozzarella between two matching onion rings, fitting it snugly in the gap. Repeat with all rings.
Place the stuffed onion rings on a tray and freeze for at least 1 hour. This helps prevent the cheese from melting too quickly during frying.
Prepare three bowls:
In the first bowl, add the flour.
In the second bowl, whisk together the eggs and milk.
In the third bowl, combine panko breadcrumbs, regular breadcrumbs, garlic powder, paprika, salt, and black pepper.
Remove the frozen onion rings from the freezer. Coat each ring in flour, then dip into the egg mixture, and finally coat thoroughly with the breadcrumb mixture.
For extra crispiness, repeat the egg and breadcrumb coating one more time.
Heat vegetable oil in a deep pan to 350°F (175°C).
Fry the onion rings in batches for 2 to 3 minutes per side, or until golden brown and crispy.
Remove with a slotted spoon and place on paper towels to drain excess oil.
Serve immediately while hot and the cheese is still gooey.
For a spicy version, add 1/2 teaspoon cayenne pepper to the breadcrumb mixture.
You can substitute mozzarella with cheddar cheese sticks for a sharper flavor.
For an air fryer option, spray the coated rings lightly with cooking spray and air fry at 375°F (190°C) for 8 to 10 minutes, flipping halfway through.
Add Italian seasoning to the breadcrumbs for a herb-infused twist.
Try serving with marinara sauce, ranch dip, or a garlic yogurt sauce for extra flavor.
Storage/Reheating
Store leftover onion rings in an airtight container in the refrigerator for up to 3 days.
To reheat, bake in a preheated oven at 375°F (190°C) for 8 to 10 minutes until heated through and crispy. Avoid microwaving, as it can make them soggy.
You can also freeze cooked onion rings for up to 1 month. Reheat directly from frozen in the oven at 400°F (200°C) for about 12 to 15 minutes.
FAQs
Can I prepare these ahead of time?
Yes, you can assemble and coat the onion rings, then freeze them until ready to fry.
Why do I need to freeze the onion rings before frying?
Freezing prevents the mozzarella from melting too quickly and leaking out during frying.
Can I bake these instead of frying?
Yes, bake at 400°F (200°C) for 15 to 20 minutes, flipping halfway, though they may be slightly less crispy than fried.
What oil is best for frying?
Vegetable oil, canola oil, or sunflower oil work well due to their high smoke points.
How do I prevent the coating from falling off?
Make sure to pat the onion rings dry before coating and press the breadcrumbs firmly onto the surface.
Can I use fresh mozzarella?
Low-moisture mozzarella sticks are recommended because fresh mozzarella contains too much moisture and may leak.
How thick should I slice the onion?
About 1/2 inch thick to create enough space for the cheese filling.
Can I make them gluten-free?
Yes, substitute the flour and breadcrumbs with gluten-free alternatives.
Why are my onion rings soggy?
The oil temperature may be too low. Ensure it stays around 350°F (175°C) for crispy results.
What sauces pair well with these onion rings?
Marinara sauce, spicy mayo, garlic aioli, or a simple ketchup dip all complement the cheesy flavor.
