Deliciously crispy onion rings are the perfect side dish for homemade burger night. These Oven Baked Onion Rings are a much lighter option than the deep fried version. A lightly seasoned but crispy coating still gives these onion rings all the flavour and crunch you would expect, but they are baked rather than fried. Baked onion rings are the perfect healthy, but comforting, side dish.

We love the crunch of a stack of onion rings and they are a must when we make homemade burgers. Easy to make and just 20 minutes in the oven. Baking onion rings in the oven still makes them crispy, but a lot lighter.
We pair them with our favourite dipping sauces for a nice little snack too. You can even adapt the seasoning to make different flavoured onion rings. You can also freeze this baked onion rings recipe, so they are perfect for keeping a stash in your freezer for easy meals.

Ingredients and Substitutions
A full ingredients list, along with US Customary and Metric measurements, can be found in the recipe card at the end of this post.
- Onion - You will need large onions for this, to be able to get decent sized onion rings.
- Eggs - This is to help the breadcrumbs stick to the onion rings.
- Breadcrumbs - You can use any breadcrumbs to make onion rings in the oven, but we love panko breadcrumbs as they make the onion rings really crispy.
- Seasoning - We used a Cajun seasoning, but you can use your favourite seasoning blend. Italian or Fajita work well too.
- Flour -This is what the onions are first coated in, as it helps to soak up any moisture. We used plain flour (all purpose flour).
More ingredient substitutions and variations can be found in the recipe card.
How to Make Baked Onion Rings - Step by Step
Prep: Preheat your oven to 200°C/180°C(fan)/400°F/Gas 6. Line a large baking sheet with parchment paper.
- Step 1: Slice the onions thickly and separate into rings.
- Step 2: Mix together the flour and Cajun seasoning in a bowl. Put the breadcrumbs in separate bowl, and whisk the eggs in a third bowl.
- Step 3: Dip the onion slices in the flour mixture, then the egg and then roll in the Panko breadcrumbs until they are completely covered. Put them onto a lined baking tray.
- Step 4: Bake for 20 minutes, flipping them over halfway.
Serving Suggestions
Onion rings are the perfect side for a burger. So, why not try our Mexican Burger, Greek Turkey Burger, Baked Chicken Burger, Hidden Vegetable Beef Burgers or Salmon Burgers?
If you are looking for some other sides to go with the burger and onion rings, then I recommend our Garlic Potato Wedges, Baked Polenta Fries, The Best Greek Potatoes, Baked Sweet Potato Fries, or Baked Carrot Fries.
Onion rings need dip too, right? Our Homemade Healthier Tomato Ketchup, Healthy BBQ Sauce and Healthy Ranch Dressing all go really well with these baked onion rings.
Tips For Making The BEST Baked Onion Rings
- You can use any breadcrumbs you like, however we find that panko gets them nice and crispy.
- Feel free to change the seasoning used. You could swap Cajun for Mexican, Italian or Curry Powder.
- Don't crowd the baking sheet and make sure there is space between each onion ring.
- Cooking times will depend on your own and how crispy you like your onion rings. Keep an eye on them and take them out when they are cooked to your liking.
- Cooking times will also vary between the different sized rings. The smaller inside ones, if using, will need to be taken out of the oven before the larger outer rings used.
- Add some extra flavour to these by mixing some grated Parmesan into the breadcrumbs.
- When cooking onion rings in the oven, if you want them extra crispy then you can spray them with a little bit of oil before cooking.
Frequently Asked Questions
Baked onion rings can be frozen for up to 2-3 months - we always have some stashed away in our freezer.

They can also be kept in the refrigerator in an airtight container for 3 days.

I had no idea you could bread onion rings and bake them. This is awesome!
Danielle Wolter says
What an awesome idea! I loved how great these came out - crispy and perfect!
Beth Sachs says

Jacqueline Meldrum says
Loving the onion rings, but I'm totally distracted by your gorgeous new photography board.
Betty says
I followed the directions but had trouble getting the panko mix to stick to and cover the onion. Any suggestions?
Dannii says
If the onion rings were dipped in to flour first, then egg, then the panko should stick to them. Some will fall off, but the majority should stay on. As you can see from our photos, there are some gaps in the breading.
Alice | SkinnySpatula says
Absolutely brilliant idea! I try to stay away from deep-fried stuff, but I love onion rings, so I'll give these ones a try.
Jacqueline Debono says
These oven-baked onion rings are brilliant. We had them with homemade burgers over the weekend. Will be making again for sure!
