Crispy Keto Onion Rings are a crunchy, flavorful snack that brings all the fun of traditional onion rings without the extra carbs. These rings are golden and crispy on the outside, with a tender, sweet onion center that makes every bite pop with flavor. Perfect for anyone looking to enjoy a tasty appetizer while sticking to a low-carb lifestyle.
I love making these onion rings when I want something satisfying but also healthy enough to feel good about. Using a simple keto-friendly coating means they crisp up perfectly in the oven or air fryer without needing a ton of oil. I always find that they’re a huge hit whether we’re having a casual snack or serving them up for guests.
My favorite way to enjoy these crispy keto onion rings is with a side of creamy ranch or a spicy dipping sauce. They’re great for sharing at get-togethers or just when you want a crunchy treat that feels a little special. If you’re craving that classic onion ring crunch but want to keep it low carb, these are your new go-to!
Key Ingredients & Substitutions
Onions: White or yellow onions work well because they have a good balance of sweetness and mild flavor. White onions are slightly sharper, while yellow onions are sweeter. Either suits this recipe nicely.
Almond Flour: This is the main low-carb coating. If you don’t have almond flour, crushed pork rinds make a fantastic keto-friendly substitute and can add extra crunch.
Parmesan Cheese: Adds flavor and helps with crispiness. If you’re dairy-free, try nutritional yeast for a cheesy hint instead.
Eggs & Almond Milk: These help the coating stick to the onion rings. You can swap almond milk with any unsweetened low-carb milk like coconut or macadamia milk.
Spices (Garlic Powder, Smoked Paprika, Salt, Pepper): These bring out flavor in the coating. Feel free to adjust spices to your taste or add a pinch of cayenne for heat.
How Can You Make Your Keto Onion Rings Extra Crispy?
Getting that perfect crispiness on keto onion rings can be tricky since this recipe doesn’t use traditional breadcrumbs. Here’s my tip:
- Use a Double Coating: Dip the onion rings twice in the egg mixture and almond flour mixture. This adds thickness to the crust, making it crunchier.
- Press the Coating Firmly: After dredging the onion in the coating, gently press it on with your fingers to ensure it sticks well.
- Use Cooking Oil Spray: Lightly spray the onion rings before baking to help them brown and crisp up.
- Don’t Overcrowd the Tray: Space the rings out so hot air can circulate evenly, which helps them crisp instead of steam.
- Flip Halfway Through Cooking: This ensures both sides get evenly golden and crispy.
With these tips, your keto onion rings will come out perfectly crispy and delicious every time!
Equipment You’ll Need
- Sharp knife – to slice the onions evenly into perfect rings.
- Baking sheet – for crisping the onion rings in the oven without mess.
- Parchment paper – keeps the rings from sticking and makes cleanup easy.

Flavor Variations & Add-Ins
- Try adding cayenne pepper or chili powder to the coating for a spicy kick.
- Swap Parmesan for shredded cheddar to add a sharper, cheesy flavor.
- Mix in dried Italian herbs like oregano and basil for an herby twist.
- Use sliced zucchini or eggplant instead of onions for a different low-carb veggie ring.

How Much Time Will You Need?
This recipe takes about 10 minutes to prepare and 15–20 minutes to bake, so you’ll have tasty keto onion rings ready in around 25–30 minutes total. It’s a quick and easy low-carb appetizer that’s perfect for snack time or parties!
Step-by-Step Instructions:
1. Preheat and Prepare:
Start by preheating your oven to 425°F (220°C). Line a baking sheet with parchment paper and lightly spray it with cooking oil to keep the onion rings from sticking.
2. Slice the Onions:
Cut your onion into about ½-inch thick rings. Carefully separate each ring, as these will be the base for your crispy coating.
3. Make the Breading Mixture:
In a shallow bowl, mix together almond flour, Parmesan cheese, garlic powder, smoked paprika, salt, and black pepper. This flavorful blend will create a crunchy, tasty crust.
4. Mix the Wet Ingredients:
In another bowl, whisk the eggs with the unsweetened almond milk until everything is smooth and combined. This helps the coating stick to the onion rings.
5. Coat the Onion Rings:
Dip each onion ring into the egg mixture first, letting any extra drip off. Then, dredge it in the almond flour mixture, pressing gently to make sure the coating sticks well. Place the coated rings on your prepared baking sheet.
6. Bake to Crispy Perfection:
Spray the tops of the coated rings lightly with cooking oil spray to encourage crispiness. Bake in the oven for 15 to 20 minutes, flipping the onion rings halfway through cooking to get both sides golden brown and crunchy.
7. Serve and Enjoy:
Once baked, remove the onion rings and garnish with fresh chopped parsley. Serve warm alongside your favorite low-carb dipping sauce like keto-friendly marinara or ranch dip.
Can I Use Frozen Onions for This Recipe?
It’s best to use fresh onions for the crispiest results. If you use frozen, make sure to thaw and pat them dry thoroughly to avoid sogginess in the coating.
Can I Air Fry These Keto Onion Rings Instead of Baking?
Absolutely! Air fry at 400°F (200°C) for about 10-12 minutes, flipping halfway through, until golden and crispy. Just spray lightly with oil before air frying.
How Should I Store Leftover Keto Onion Rings?
Store leftovers in an airtight container in the fridge for up to 2 days. Reheat in the oven or air fryer to restore crispiness—avoid microwaving to prevent sogginess.
What Are Good Dipping Sauces for Keto Onion Rings?
Keto-friendly dips like ranch dressing, low-carb marinara, or a spicy mayo made with mayonnaise and hot sauce all pair wonderfully with these onion rings.
