Ingredients
- Main Components: 1 large onion, sliced into thick rings

- Main Components: 1 cup whole milk
- Main Components: 1 large egg, beaten

Instructions
- Assemble Onion Rings:
- Pair two slices of onion rings, one larger than the other with space between them when the smaller is placed inside the larger. Slice mozzarella cheese to fit the space between the rings. Place cheese between the onion pieces and secure with a toothpick.
- Prepare Dry Mixture:
- Heat oil in a deep cooking pot. Combine all dry ingredients (flour, baking powder, salt) in a bowl and mix well. Dredge all onion rings in the dry mixture and place on a wire rack.
- Create Batter:
- Combine milk and beaten egg, mix well. Pour this mixture into the bowl with remaining dry ingredients and mix until a batter is formed.
- Coat Onion Rings:
- Dip the onion rings in the batter mixture, then place back on the wire rack to let excess batter drip. Coat with Panko breadcrumbs.
- Fry to Perfection:
- Fry one side until golden brown, then turn over and fry the opposite side until golden brown.
- Serve:
- Remove toothpicks and serve warm with marinara sauce. Share and enjoy!

Recipe FAQs
- → How do I keep the cheese from leaking out?
Secure the onion rings tightly with toothpicks and ensure a complete batter and breadcrumb coating to seal the cheese inside.
- → What type of cheese works best?
Low-moisture mozzarella sticks are ideal—they melt well and hold their shape during frying.
- → Can I bake instead of fry?
Yes, you can bake them at 425°F for 20–25 minutes, flipping halfway through, but they won’t be as crispy as when fried.
- → What sauce pairs well with these?
Marinara sauce is a classic choice, but garlic aioli or ranch also complement the cheesy, savory flavor.
- → Can these be made ahead?
You can prep and freeze them before frying. When ready, fry directly from frozen—just extend the cook time slightly.
