These mozzarella-packed onion rings come out perfectly golden and crisp from the oven every time. That gooey cheese melt in the middle? It never sticks around long at my house. They're baked, not fried, but you won't miss the crunch or the flavor.
Every time these come out of the oven, my kids can’t wait to grab one. I used to think the cheese would leak out, but the way I do it now, you’ll get a perfect, gooey middle every single time.
Tasty Ingredients
- Large onions: You want hefty ones with tight skins for best slices. Bigger onions give you sturdy rings to stuff and hold up well.
- Mozzarella cheese: Always reach for whole milk mozzarella if you want that melt and rich, cheesy bite.
- Breadcrumbs: Fresh is best here. Panko gives extra crispness, while normal ones keep it traditional.
- Flour: This helps everything stick. Choose regular all-purpose flour for smooth coating.
- Eggs: Grab some fresh, room temperature eggs so your breadcrumbs don’t fall off.
- Paprika: Adds a whisper of smoky flavor. Pick your favorite—smoky or sweet.
- Garlic powder: For a tasty boost in the coating, make sure it’s super fragrant.
- Salt and pepper: Go with flaky salt if possible and always crack your own pepper for a nice kick.
Easy How-To
- Get Ready To Bake:
- Line your tray with parchment, warm up the oven to four hundred, and set aside enough space so the rings don’t squash together.
- Breading Time:
- Set up three shallow bowls: one flour, one with whipped eggs, and one mixing up breadcrumbs, salt, pepper, garlic powder, and paprika all together.
- Slice Up Onions:
- Peel whole onions, then cut nice and thick rings—about half an inch. Gently separate them so each ring holds its own shape for stuffing.
- Stuff With Cheese:
- Pack a pinch of shredded mozzarella inside every ring and press it in so it doesn’t fall out.
- Coat Each Ring:
- Start with flour, then cover fully with egg, then press into breadcrumbs and coat all sides. Make sure the cheese is fully inside the crust.

The cheese stretch is what everyone’s waiting for—pulls as you bite in, pure comfort and always gets smiles. It reminds me of fun family movie nights when I was a kid. My brother and I would fight over who got the longest gooey pull.
Keep ‘Em Fresh
If you’ve got leftovers, just keep them sealed up tight in the fridge for up to two days. Warm them up in a hot oven or toaster to bring the crunch back. Skip the microwave—it just makes them soft. Thinking ahead? Freeze before baking and cook straight from the freezer, just let them go about five extra minutes.
Swap-Ins
No mozzarella? Go for provolone or Monterey Jack if you’ve got it. For extra crunch, use gluten-free breadcrumbs or even smash up some cornflakes. Want a spicy touch? Add a dash of cayenne or chili powder to your breadcrumb mix.
How To Serve
Dip these bad boys in whatever sauce you love—honey mustard, marinara, ranch, you name it. Pile ‘em on a plate with a bright green salad for contrast, or stack a few on a veggie burger if you’re feeling wild.

Recipe FAQs
- → How do you keep the cheese from leaking out?
Wrap the mozzarella snug in each onion ring, using lots of flour, egg, and crumbs to lock it in before baking. That helps keep the cheese right where it belongs.
- → What's the best kind of onion for this?
Grab big yellow or sweet onions—they've got fat rings that make stuffing quick and simple. Plus, they're sturdy for dipping and baking.
- → Can you put other cheese inside?
Absolutely! Try cheddar or provolone if you'd like. Slice or shred whatever you use so it packs right into the rings.
- → What’s the trick to more crunch?
Pop the rings on a wire rack or flip them as they cook. And don’t let the crumb mix get soggy—it should be just enough to stick but still light.
- → Is it okay to prep these ahead?
Totally fine! Get everything coated and in the fridge, then just bake when you’re hungry. Eat them right after baking so they stay crispy.
