Why You'll Love This Recipe
- High-protein and low-carb friendly
- Crispy outside with a soft, sweet onion center
- Made with just a few simple ingredients
- Perfect snack, appetizer, or side
- Oven or air fryer friendly
- Fun and surprisingly easy to make
Ingredients
- 1 large onion, sliced into thick rings
- 1 cup shredded mozzarella cheese
- ½ cup grated parmesan cheese
- 1 large egg
- ½ teaspoon garlic powder
- ½ teaspoon paprika
- Salt and pepper to taste
Ingredient Notes & Substitutions
- Onions: Yellow onions work best for a sweet, balanced flavor.
- Mozzarella: This melts into a stretchy coating that crisps beautifully.
- Parmesan: Adds that salty, golden crust on the outside.
- Egg: Helps bind everything together so the coating sticks.
If your mixture feels a little sticky, that's completely normal. It will firm up as it cooks.
Instructions
- Preheat your oven to 400°F (200°C) or your air fryer to 375°F. Line a baking sheet with parchment paper.
- Separate the onion slices into rings and set aside.
- In a bowl, mix mozzarella, parmesan, egg, garlic powder, paprika, salt, and pepper until combined.
- Take each onion ring and coat it with the cheese mixture, pressing gently so it sticks all around.
- Place the coated rings on the prepared baking sheet, leaving space between each one.
- Bake for 15-18 minutes, or until the edges turn golden and crisp.
- Let them cool slightly before serving. They'll firm up and become even crispier as they rest.
Pro Tips for Success
- Use thick onion slices so they hold their shape.
- Don't overcrowd the pan or they won't crisp properly.
- Let them cool for a few minutes for the best texture.
- Flip halfway through cooking if you want even browning.
I tested these a few times, and that little resting step really makes them crisp up perfectly.
Storage and Reheating
- Store in the fridge for up to 2 days in an airtight container.
- Reheat in the oven or air fryer to bring back the crispiness.
- Avoid microwaving, as it softens the coating.
Make Ahead & Freezing
- Prepare and coat the rings ahead of time, then refrigerate until ready to bake.
- Freeze uncooked rings on a tray, then transfer to a container.
- Cook straight from frozen, adding a few extra minutes.
Tips and Variations
- Spicy version: Add chili powder or cayenne for heat.
- Herb twist: Mix in dried oregano or Italian seasoning.
- Extra crunch: Sprinkle a little extra parmesan on top before baking.
- Dipping sauces: Serve with keto-friendly ranch or garlic dip.
- Mini bites: Use smaller onion rings for snack-sized portions.
FAQs
