As a dietitian, I’m a big fan of getting more veggies on our plates in fun and delicious ways—this is definitely one of those! Plus, I love a good better-than-takeout spin. (I mean who doesn’t love a nice plate of chicken tenders?) so I wanted to see if I could take another fave fast food of mine, onion rings, and make it my own. I have to say these turned out even better than I had hoped for!

How to Make Baked Onion Rings Crispy

These baked, DIY onion rings only take 15 minutes of prep and 5 simple ingredients!

There’s nothing quite like a deep fryer to get that perfect crisp…or so I thought! But I was pleasantly surprised to see how crispy these onion rings got! They can be made without any fancy kitchen equipment (no deep-fryer or air-fryer needed!) but having an oil you can spray is key during prep.

Here are a few tricks to make them a delicious crispy success!

  1. Line your baking sheet with parchment paper to prevent onion ring coating from sticking to the pan.
  2. Spray a high heat oil like avocado oil on the parchment paper before laying onion rings down.
  3. Spray another coat of oil on top of the onion rings before baking (a spray works best so as not to soak the delicate panko breading—and makes for the most crispy result!)
  4. Cook at a high heat; I bake them at 425F.

Making the Perfect Panko Breading

Panko breadcrumbs make the perfect crisp coating for onion rings. These breadcrumbs are made from crustless bread and have a lighter texture with larger flakes. Because of this, they don’t soak up as much grease and they stay crispier longer. 

Tip: I added flour to the mix for better overall coverage of the onion pieces and a nice combination of textures.

For these onion rings, I kept the seasoning simple with just flour, panko breadcrumbs, and seasoning salt. Here are a few more ideas for spices you could add to the breading to add variation to your flavors:

  • Cajun or creole seasoning
  • Lemon pepper
  • Paprika
  • Dried herbs like chives or dill

Ingredient Replacements for Vegan or Gluten Free Onion Rings

Vegan:

If you want to make this crispy snack vegan, simply replace the egg with a flax or chia egg! As a bonus, enjoy the benefits of added plant-powered fats from these might seeds!

Gluten-Free:

To make these oven-baked onion rings gluten free, replace the flour with your favorite gluten-free flour option. Panko breading traditionally contains gluten, but many brands have come out with gluten-free versions. Be sure to check that the label is clearly marked gluten-free!

Health Benefits of Onions

Did you know onions are actually quite the nutrition powerhouses? Don’t be fooled by their color (or lack thereof). They are jam-packed with nutrition!

Onions are part of the allium family—like garlic and leeks—and they boast a ton of nutrition benefits:

  • They’re a great source of antioxidants, like flavonoids which help prevent free radical damage to our cells
  • They provide anti-inflammatory properties which support heart health and may help to prevent other chronic disease
  • They contain Inulin, a soluble fiber and prebiotic which provides food for the healthy bacteria in our gut and support overall gut health

Description

You won’t be able to stop eating these crispy homemade onion rings once you try them, trust me! They are coated in a light panko batter and oven-baked to golden perfection. Serve them with your favorite dipping sauce for an easy appetizer that everyone will love!

Ingredients

Scale
  • 1 medium onion, sliced into ¼ inch rings
  • ¼ cup whole wheat flour
  • 1 large egg
  • 1 cup panko bread crumbs
  • Seasoning salt or seasoning of choice, approx. ¼ tsp. Adjust to taste
  • Avocado oil spray (you can also add your own oil into a spray bottle)

Instructions

  1. Preheat the oven to 425°F.
  2. If you haven’t already, slice your onion into ¼ inch rings.
  3. Line two baking sheets with parchment paper or foil and and spray or lightly grease with avocado oil.
  4. Next, set up your dipping station: Add your flour to a large ziplock bag. Take out 2 bowls. Add your egg to one bowl and beat until fully mixed. Add half of the breadcrumbs and seasoning salt to the other bowl. (It works best to do 2 batches of the breadcrumbs, otherwise they get too wet from the egg and clump together).
  5. Put your onion rings into the bag with flour and shake to coat evenly. Removing the rings one at a time, dip them into the egg bowl, then into the breadcrumb mixture. Place the onion ring on your baking sheet in (spaced out and single layered). To make more room on your sheets, you can place the smaller rings inside the bigger ones before baking. When you run out of breadcrumbs, add the remaining breadcrumbs and seasoning salt, then repeat until all rings are coated and placed on your sheet.
  6. Spray the tops with more avocado oil. This will help them brown and crisp up.
  7. Bake for 15-20 minutes, flipping half way through. Cook until golden brown and nicely crisp.

Notes

  • To make these crispy, oven-baked onion rings vegan, use a flax egg or a chia egg in place of the real egg.
  • To make them gluten-free, opt for a gluten-free flower and gluten-free panko bread crumb option
