These Parmesan Onion Rings are crispy, flavorful, and incredibly easy to make with just a few ingredients. Whether you're craving a savory snack or need a crowd-pleasing appetizer, this recipe will definitely satisfy your taste buds. The combination of grated Parmesan cheese and crunchy breadcrumbs adds a delicious twist to the classic onion ring, making them irresistible.

Parmesan Onion Rings

Ingredients

2 large onions, sliced into rings

1 cup all-purpose flour

1 teaspoon garlic powder

1 teaspoon onion powder

½ teaspoon paprika

½ teaspoon salt

¼ teaspoon black pepper

1 cup grated Parmesan cheese

2 large eggs, beaten

½ cup breadcrumbs (preferably panko)

Olive oil for frying

(Tip: You'll find the full list of ingredients and measurements in the recipe card below.)

Directions

Begin by slicing the onions into ½-inch rings and separate them.

In a shallow bowl, mix together the flour, garlic powder, onion powder, paprika, salt, and black pepper.

In another shallow bowl, beat the eggs.

In a third shallow bowl, combine the grated Parmesan cheese and breadcrumbs, mixing well.

Heat olive oil in a large skillet over medium-high heat. Ensure there’s enough oil to cover the bottom of the pan.

Coat each onion ring in the seasoned flour mixture, then dip it into the beaten eggs, and finally coat it with the Parmesan-breadcrumb mixture. Press gently to make sure the coating sticks.

Fry the coated onion rings in batches, cooking for 2-3 minutes on each side, or until golden and crispy.

Once crispy, remove the onion rings from the oil and place them on a paper towel-lined plate to drain excess oil.

Serve immediately with your favorite dipping sauce.

Variations

If I want to switch things up, I sometimes add a bit of cayenne pepper to the flour mixture for a subtle kick of heat. For a different flavor profile, I’ve also tried swapping the Parmesan with a combination of cheddar or mozzarella for a cheesy twist. Another variation could be adding some dried herbs like oregano or thyme to the breadcrumb mixture for a more aromatic touch. You can also bake these onion rings in the oven for a healthier version.

Storage/Reheating

To store any leftovers, I place the cooled onion rings in an airtight container. They’ll stay fresh in the fridge for up to 2 days. To reheat them, I recommend placing them in a preheated oven at 375°F (190°C) for about 10 minutes to restore their crispiness. You can also use an air fryer to reheat them for a quick fix.

FAQs

How do I make these onion rings extra crispy?

To make these onion rings extra crispy, make sure the oil is hot enough before frying them. Also, using panko breadcrumbs will help create a crunchier texture. Pressing the coating onto the onion rings as you dip them also ensures the crispy coating sticks better.

Can I make these without frying?

Yes, you can bake these onion rings for a healthier version. Preheat your oven to 400°F (200°C), place the coated onion rings on a baking sheet, and spray them lightly with cooking spray. Bake for about 20-25 minutes, flipping halfway through, until golden and crispy.

Can I use frozen onion rings?

While fresh onion rings will give the best results, you can use frozen onion rings if you're in a pinch. Just make sure to thaw them completely before dipping them in the coating.

Can I make these onion rings ahead of time?

You can prep these onion rings by coating them the night before and refrigerating them. When you’re ready to fry, just heat the oil and cook them as usual.

What’s the best dipping sauce for Parmesan onion rings?

I love pairing these onion rings with a tangy dipping sauce like ranch or a zesty marinara. For a little heat, a spicy mayo or Sriracha dipping sauce works great too!

Conclusion

Parmesan Onion Rings are an easy, delicious treat that will elevate any meal or snack time. The crispy, cheesy coating and the tender onion inside make them the perfect choice for an appetizer or side dish. With simple ingredients and quick preparation, I always find myself coming back to this recipe whenever I crave something savory and satisfying. Whether you’re enjoying them on their own or paired with a favorite dipping sauce, these onion rings are sure to be a hit!
