How to Make this Healthier Onion Ring Recipe
This recipe is easy to make! Simply slice onions into rings, then dredge in the batter.
Step 1: Prep the Onions. Slice the onions into thick rings and separate them. Pat dry with a paper towel to help the coating stick better.
Step 2: Set Up the Breading Station. To make the batter, mix flours and seasonings in a large bowl, then add in your eggs and milk. Coat onion rings in the batter, tapping off any extra. You only need a thin layer of batter!
Step 4: Cook Until Crispy. I went for the frying pan because baked onion rings never turn out quite as tasty in my opinion. I use avocado oil(I get a HUGE bottle at Costco!) due to it's high smoke point plus it's neutral tasting. You only need a few tablespoons to get these onion rings nice and crispy. No deep frying or refined oils needed!
How to Make Garlic Aioli Sauce
While the onion rings cook, stir together mayonnaise, ketchup and seasonings.Taste and adjust as needed. The result is a creamy, tangy garlic aioli dipping sauce that pairs perfectly with the crispy onion rings.
This sauce also works great on burgers, sandwiches, roasted vegetables, or as a dip for French fries.
Serving Ideas
These grain-free onion rings are incredibly versatile:
- Serve as a game day appetizer
- Pair with burgers or sandwiches
- Add to a snack board or appetizer platter
- Serve alongside grilled chicken or steak
- Enjoy as a late-night snack
Storage & Reheating
These onion rings are best enjoyed fresh, but leftovers can be stored in the refrigerator for up to 2 days. Reheat in the oven or air fryer to bring back the crispiness. Skip the microwave if possible.

Best recipe ever and so easy! Have you used this same batter to fry other foods? I loved how light and crispy it is.

Hey Christina,that made my day! I have not used it to fry other foods, but I'm sure you totally could! Let me know if you try 🙂 I also have another batter recipe I've used for chicken and shrimp that you might enjoy trying. It's not grain-free, but uses gluten free all purpose flour. Here's a link to that: https://thriving-glutenfree.com/gluten-free-sweet-and-sour-chicken/
