Crispy Keto Onion Rings are a fantastic low-carb treat that bring all the crunch and flavor of traditional onion rings without the extra carbs. These rings have a crispy, golden outside and a tender, sweet onion center that makes them irresistible. They’re perfect if you’re looking for a snack or appetizer that fits into a keto lifestyle but still feels like a little indulgence.
I love making these crispy onion rings when I want something tasty and satisfying without breaking my carb goals. The coating gets really crunchy, and you won’t believe they’re keto-friendly. One tip I’ve found helpful is to slice the onions evenly and soak them in cold water for a bit—it helps keep them nice and crispy while frying, which is key to getting that perfect texture.
These keto onion rings are great served with your favorite dipping sauce, like a zesty ranch or a spicy mayo. I usually pair them with a fresh salad or some grilled meat for a simple, balanced meal. They’re always a hit when guests come over, and I love how easy they are to whip up on a busy day. Crispy, crunchy, and low carb—what’s not to love?
Key Ingredients & Substitutions
Onions: Yellow onions are my favorite because they’re sweet and firm, which holds up well when fried. If you only have white onions, no worries—they work fine too.
Almond Flour: This is the base for the crispy coating in place of regular flour. You could also try crushed pork rinds for an even lower carb option with extra crunch.
Parmesan Cheese: Adds flavor and helps with browning. If you don’t have Parmesan, a hard cheese like Pecorino or Grana Padano can work too.
Oil: Use avocado oil or coconut oil because they handle high heat well and keep it keto-friendly. Avoid vegetable oils that can burn easily.
How Can I Get the Onion Rings Extra Crispy Without Soaking Up Too Much Oil?
The frying part is key to crispy onion rings that aren’t greasy:
- Soak rings in cold water: This step helps the onions stay crunchy, not soggy.
- Dry thoroughly: Make sure the rings are very dry before coating—moisture causes oil splatter and sogginess.
- Coating layers: Dip in the egg mix, then almond flour blend, and press the coating firmly on all sides for a thick crust.
- Fry at the right temperature: Oil around 350°F ensures the crust crisps quickly without soaking up oil.
- Don’t overcrowd the pan: Cook in batches so the oil temperature stays steady and the rings fry evenly.
Equipment You’ll Need
- Sharp knife – for slicing the onions evenly into rings, which helps them cook well.
- Mixing bowls – you’ll need two, one for the egg wash and one for the coating mix.
- Deep skillet or heavy-bottomed pot – perfect for frying and keeping oil at the right temperature.
- Thermometer – handy to check oil temperature so rings get crispy without absorbing too much oil.
- Slotted spoon or tongs – makes it easy to lift out the fried rings without breaking them.
- Paper towels – to drain excess oil and keep onion rings crispy after frying.
Flavor Variations & Add-Ins
- Try adding smoked paprika or cayenne pepper to the coating for a little spicy kick.
- Mix in finely chopped fresh herbs like parsley or thyme to the almond flour for a fresh twist.
- Swap Parmesan for nutritional yeast to keep it dairy-free while still adding a cheesy flavor.
- Add a pinch of cumin or chili powder for a smoky, warm flavor that pairs great with dipping sauces.

How Much Time Will You Need?
Getting these crispy keto onion rings ready takes about 15 minutes for preparation, including slicing and soaking the onions. Frying them will take another 10-15 minutes in batches. So altogether, plan on around 30 minutes from start to finish. This recipe is quick and rewarding—you get crispy, flavorful rings ready to enjoy in no time!
Step-by-Step Instructions:
1. Preparing the Onion Rings:
Peel your onions and slice them into rings about ¼ inch thick. Carefully separate the rings so you have individual circles. Place these onion rings in a bowl of cold water and let them soak for about 10 minutes. This soaking step helps keep the onions crisp when fried. After soaking, drain and pat the rings very dry with paper towels—this is important to get a crunchy texture.
2. Making the Coating:
In a shallow dish, mix together the almond flour, grated Parmesan cheese, paprika, garlic powder, onion powder, salt, and black pepper. In a separate bowl, whisk the eggs and heavy cream together until smooth. This egg mixture will help the coating stick to the onions.
3. Frying the Onion Rings:
Heat your chosen oil in a deep skillet or fryer to about 350°F (175°C). One at a time, dip each onion ring into the egg mixture, letting the excess drip off. Then dredge it in the almond flour mixture, pressing gently to make sure the coating sticks well. Carefully place coated rings in the hot oil and fry them in batches for 2-3 minutes each side or until golden brown and crispy. Don’t overcrowd the pan, so they cook evenly.
4. Draining and Serving:
Once fried, remove the onion rings with a slotted spoon and set them on paper towels to drain any extra oil. Serve your crispy keto onion rings warm with your favorite low-carb dips like ranch dressing or spicy mayo for an extra tasty bite!
Can I Bake These Keto Onion Rings Instead of Frying?
Yes! For a healthier option, bake them at 400°F (200°C) on a parchment-lined tray for about 15-20 minutes, flipping halfway through. They won’t be as crispy as fried but still delicious.
What Can I Use Instead of Almond Flour?
You can substitute crushed pork rinds for a zero-carb coating or use coconut flour, but coconut flour absorbs more moisture—use less and add an extra egg for better binding.
How Should I Store Leftover Onion Rings?
Store leftovers in an airtight container in the fridge for up to 2 days. Reheat them in a hot oven or air fryer to help bring back their crispiness.
Can I Prepare the Onion Rings Ahead of Time?
You can slice and soak the onions a few hours ahead and keep them refrigerated. Coat and fry just before serving for best texture and flavor.
