How to Make It

Slice & Hollow the Onion Rings

Peel your onions and cut them into thick rings—about ½ inch. Pop out the inner layers to make pairs of rings with a gap in between for stuffing. Save the small bits for soup or stir-fry!

Tuck in the Mozzarella

Take a string cheese or cut-up mozzarella stick, and fit it snugly between two onion rings like a cheesy donut sandwich. Press gently to secure them—don’t worry, the coating will help hold them together.

Coat and Bread

Set up a dredging station: flour in one bowl, beaten eggs in another, and a seasoned panko mixture in the third. Dip each stuffed ring in flour, then egg, then panko. Press those crumbs on tight!

Chill Before Cooking

Pop the coated rings in the freezer for at least 30 minutes. This helps them stay intact during cooking and keeps the cheese from escaping.

Fry or Bake

Fry in hot oil until golden and crisp, about 2–3 minutes per side. Or bake at 425°F for 15–18 minutes, flipping halfway. You can also air-fry for 12–14 minutes!

Make That Garlic Butter

Melt butter in a small saucepan, add minced garlic, and sauté until fragrant—about a minute. Drizzle over the hot onion rings, then shower with parsley.

Pro Tips for Success

  • Use low-moisture mozzarella to avoid excess leaking during cooking.
  • Don’t skip the freezing step—it keeps the cheese from oozing too fast.
  • Make sure your oil is hot (350°F) if frying—cool oil = soggy crust.
  • Press the panko coating on firmly so it sticks and crisps up evenly.
  • Let them cool a minute before serving—the cheese is molten!

Flavor Variations

  • Spicy kick: Add cayenne or chili flakes to the panko mix
  • Cheese swap: Try pepper jack or cheddar for a new flavor vibe
  • Garlic overload: Add garlic powder to the panko and the butter
  • Gluten-free: Use GF breadcrumbs and flour substitutes
  • Herb boost: Add chopped basil or thyme to the garlic butter

Serving Suggestions

  • Serve with warm marinara, ranch, or garlic aioli for dipping
  • Pair with crisp beers or bubbly lemonade
  • Stack ’em on a burger for the ultimate cheesy crunch
  • Make it a platter with other finger foods like jalapeño poppers or loaded fries—or round it out with something ultra-cozy like these Creamy Garlic Sauce Baby Potatoes. Trust me, it’s a garlic lover’s dream pairing.

Make-Ahead & Storage

  • Prep ahead: Assemble and freeze uncooked rings for up to 1 month
  • Cook and store: Keep leftovers in the fridge for 3–4 days
  • Reheat: Oven or air fryer gets them crispy again—avoid the microwave!

Leftovers

  • Chop and add to grilled cheese sandwiches for a cheesy onion crunch
  • Dice and toss onto salads or in wraps for added texture
  • Reheat and dip in soup like tomato bisque for comfort food heaven

Freezing

Absolutely! Freeze after breading on a baking sheet, then transfer to a freezer bag. Cook straight from frozen—just add a couple of extra minutes to your cook time.

Reheating

For best results, use an air fryer or oven at 375°F until hot and crispy. Microwave only if you’re desperate—things get soggy fast!

FAQs

Can I use fresh mozzarella instead of sticks?
I don’t recommend it. Fresh mozzarella has too much moisture and tends to leak out or make the rings soggy.

Can these be made in the air fryer?
Yes! Air fry at 375°F for 12–14 minutes, flipping halfway through. They come out super crispy.

What onions work best?
Sweet onions are ideal because they’re mild and wide. But yellow onions work if that’s what you’ve got.

Can I make them vegan?
Sure! Use vegan cheese sticks, plant-based butter, and egg substitutes like aquafaba or flax eggs.
