Low Carb Air Fryer Mozzarella Onion Rings

These low-carb onion rings are stuffed with melty mozzarella, coated in a crispy almond flour and Parmesan crust, and air-fried until golden. A perfect keto appetizer or snack with no guilt and all the flavor.

 Ingredients (Makes about 12 rings)

1 large yellow onion, cut into ½-inch rings (use the largest outer rings)

6 mozzarella cheese sticks, cut in half (or mozzarella slices to fit inside rings)

For the Coating:

¾ cup almond flour

½ cup grated Parmesan cheese

1 tsp garlic powder

1 tsp paprika

Salt & pepper to taste

For the Wet Dip:

2 large eggs, beaten

Optional:

Low-carb marinara or ranch for dipping

Crushed pork rinds for extra crunch (optional, mix with almond flour)

 Instructions

 Prepare Onion Rings & Cheese

Separate onion slices into rings. Select pairs of similar-sized rings (one slightly smaller than the other).

Place a piece of mozzarella cheese between two onion rings to “sandwich” the cheese inside.

Tip: Use smaller inner onion rings as the top ring to hold the cheese in.

 Set Up Dredging Stations

In one bowl: whisk eggs.

In another bowl: mix almond flour, Parmesan, garlic powder, paprika, salt, and pepper.

 Coat the Onion Rings

Carefully dip each stuffed ring in the egg, coating all sides.

Press into the almond-Parmesan mixture, ensuring a good, even coating.

For best results, place rings on a tray and freeze for 20–30 minutes (optional but helps them hold shape).

Air Fry

Preheat air fryer to 375°F (190°C) for 3–5 minutes.

Place rings in a single layer in the basket. Lightly spray with cooking oil.

Air fry for 8–10 minutes, flipping halfway through, until golden and crispy.

 Tips for Success

Freezing helps prevent cheese from leaking out.

Don’t overcrowd the basket—leave space for air to circulate.

If any cheese does leak, it gets crispy and delicious!

Use block mozzarella or cheese sticks—shredded cheese is too messy.
