Crispy Keto Onion Rings are the perfect crunchy snack when you’re craving something oniony and satisfying without the carbs. These rings have a golden, crispy coating on the outside and tender, sweet onions inside. They’re super easy to make and give you all the joy of classic onion rings, just keto-style!
I love making these when I want a treat that fits my low-carb lifestyle but still feels like a special snack. The secret is in using almond flour and a bit of cheese to get that crispy crust that holds up so well. I find that frying them just right keeps them crunchy without getting greasy, and they come out tasting amazing every time.
My favorite way to enjoy these crispy keto onion rings is with a creamy ranch dip or a little spicy mayo. They’re great for movie nights, parties, or just when you want something tasty and different. I keep the recipe handy because whenever I make them, everyone asks for the secret—so good!
Key Ingredients & Substitutions
Onions: White or yellow onions work perfectly here. Yellow onions are a bit sweeter if you want extra flavor. Cut the rings evenly to ensure they cook at the same rate.
Almond Flour: This is the main low-carb coating to keep it keto-friendly. If needed, crushed pork rinds also make a crispy, tasty substitute.
Parmesan Cheese: Adds great flavor and helps create a crispy texture. You can skip it or swap with nutritional yeast for a dairy-free version.
Eggs: Act as a binder to help the coating stick. No good substitute for this one in this recipe, so keep those eggs handy.
Oil for Frying: Use avocado or coconut oil as they handle high heat well. Vegetable oil works but can affect flavor and health benefits.
How Do You Get Onion Rings Crispy Without Being Greasy?
Crispy onion rings come down to the right frying technique:
- Heat the oil properly: Keep it around 350°F (175°C). Too low and rings absorb oil; too hot and they burn quickly.
- Don’t overcrowd: Fry in small batches to keep oil temperature steady and avoid soggy rings.
- Coat well: Press the almond flour mixture firmly onto the egg-coated rings so it holds during frying.
- Drain on paper towels: This step soaks up any leftover oil, keeping your onion rings crunchy.
Equipment You’ll Need
- Sharp knife – to slice the onions evenly for consistent cooking.
- Two shallow bowls – one for the egg mixture and one for the almond flour coating.
- Deep frying pan or cast-iron skillet – holds enough oil for frying the onion rings evenly.
- Cooking thermometer – helps keep the oil at the right temperature for perfect crispiness.
- Slotted spoon or tongs – to safely remove the rings from the hot oil.
- Paper towels – for draining excess oil and keeping the rings crisp.
Flavor Variations & Add-Ins
- Try adding cayenne pepper or chili powder to the coating mix for a spicy kick.
- Swap Parmesan for shredded sharp cheddar for a richer, cheesier crust.
- Mix in finely chopped fresh herbs like parsley or thyme into the coating for fresh herbal notes.
- Use sweet onions like Vidalia for a milder, sweeter flavor when you want a softer ring.
How to Make Crispy Keto Onion Rings: Low Carb Appetizers
Ingredients You’ll Need:
- 2 large white or yellow onions
- 1 cup almond flour
- 1/4 cup grated Parmesan cheese
- 1 teaspoon garlic powder
- 1 teaspoon paprika
- 1/2 teaspoon salt
- 1/4 teaspoon black pepper

How Much Time Will You Need?
This recipe takes about 10 minutes to prepare and 15 minutes to fry the onion rings in batches. So, expect around 25 minutes total from start to crunchy finish!
Step-by-Step Instructions:
1. Prepare the Onion Rings:
Peel the onions and slice them into 1/4 to 1/2 inch thick rings. Gently separate each ring and set them aside to be coated.
2. Mix the Coating:
In a shallow bowl, combine almond flour, grated Parmesan cheese, garlic powder, paprika, salt, and black pepper. Stir until well mixed.
3. Prepare the Egg Wash:
In another bowl, whisk together the eggs and unsweetened almond milk until smooth.
4. Heat the Oil:
Pour about 1 to 1.5 inches of oil into a frying pan and heat over medium until reaching 350°F (175°C). To test, drop a pinch of coating into the oil; if it sizzles immediately, you’re ready to fry.
5. Coat the Onion Rings:
Dip each onion ring into the egg wash, making sure it’s fully coated, then dredge into the almond flour mixture. Press gently so the coating sticks well to the ring.
6. Fry the Rings:
Place the coated rings into the hot oil carefully, frying in small batches to prevent overcrowding. Fry each side for about 2-3 minutes or until golden brown and crispy.
7. Drain and Serve:
Use a slotted spoon to remove the rings and place them on paper towels to drain excess oil. Continue with the remaining rings. Serve hot with your favorite low-carb dipping sauce like ranch or spicy mayo.
Enjoy these crunchy, tasty keto onion rings that make a perfect low-carb appetizer or snack!
Can I Bake the Keto Onion Rings Instead of Frying?
Yes! To bake, preheat your oven to 400°F (200°C) and place the coated onion rings on a parchment-lined baking sheet. Spray them lightly with cooking oil and bake for about 15-20 minutes, flipping halfway through until golden and crispy.
What Can I Use as a Substitute for Almond Flour?
If you’re allergic to nuts or want a different texture, crushed pork rinds work great as a low-carb alternative. Just crush them finely before coating the onion rings.
How Do I Store Leftover Onion Rings?
Store any leftovers in an airtight container in the refrigerator for up to 2 days. Reheat them in an oven or air fryer at 350°F (175°C) for 5-7 minutes to help retain their crispiness.
Can I Use Frozen Onion Rings for This Recipe?
Fresh onions work best for crispy keto onion rings. If using frozen, thaw completely and pat dry to reduce moisture, or the coating may not stick properly and they could become soggy.
