Instructions

Let’s dive into making these cheesy onion rings:

Prepare the Onion Rings

Peel onions and cut into ½-inch thick slices. Separate into rings and pair two rings of similar size together, leaving a gap between them for the cheese.

Stuff with Mozzarella

Cut mozzarella sticks to fit between the two rings. Place cheese inside the gap and gently press the rings together.

Set Up Breading Stations

In one bowl, place flour seasoned with salt and pepper. In another, whisk eggs with milk. In a third, mix panko, plain breadcrumbs, garlic powder, onion powder, and a pinch of salt.

Bread the Onion Rings

Dredge each stuffed onion ring in flour, dip into the egg mixture, and coat generously with breadcrumbs. For an extra crispy finish, repeat the egg and breadcrumb steps once more.

Chill Before Frying

Place the breaded onion rings on a tray and refrigerate for at least 30 minutes—this helps keep the cheese from leaking during frying.

Fry to Perfection

Heat vegetable oil in a deep skillet or pot to 350°F (175°C). Fry onion rings in batches for 2–3 minutes per side, until golden and crispy. Drain on paper towels.

Make the Garlic Butter

In a small saucepan, melt butter over low heat. Add garlic and sauté until fragrant, about 1 minute. Stir in parsley if using.

Serve and Enjoy

Serve onion rings hot, drizzled with garlic butter or with a small bowl for dipping.

How to Serve Mozzarella-Stuffed Onion Rings with Garlic Butter

These onion rings are best enjoyed fresh from the fryer with:

• A side of marinara sauce for dipping

• As a side to burgers, sliders, or grilled chicken

Additional Tips

• Freeze breaded onion rings before frying for a quick make-ahead snack.

FAQ’s

1. Can I make these ahead of time?
   Yes—bread them and refrigerate or freeze until ready to fry.
2. Why is my cheese leaking out?
   Chilling before frying and ensuring a thick breading layer helps prevent leaks.
3. Can I bake these instead of frying?
   Yes—bake at 425°F for 15–20 minutes, flipping halfway, though they’ll be less crispy.
4. What other cheeses work well?
   Cheddar, pepper jack, or provolone are delicious options.
5. Can I use red onions?
   Yes, but yellow or white onions are milder and better for balancing the cheese.
6. Do I need both panko and plain breadcrumbs?
   The combo gives the best texture, but you can use just one type if needed.
7. How do I keep them warm for serving?
   Place fried rings on a baking sheet in a 200°F oven until ready to serve.
8. What oil is best for frying?
   Vegetable, canola, or peanut oil work well due to their high smoke points.
9. Can I make the garlic butter spicier?
   Yes—add red pepper flakes or a dash of hot sauce.
10. How long will leftovers last?
    Best eaten fresh, but you can refrigerate for 1–2 days and reheat in the oven or air fryer.
