Make the Best Mozzarella Stick Gluten Free Onion Rings

Perfectly Crispy: The combination of almond flour and Parmesan creates a light, golden crust, while crushed pork rinds (if used) take the crunch factor to the next level.

Melty, Gooey Cheese: Each bite delivers a warm, cheesy center that stretches just the right amount without being too runny. For best results, use classic string cheese instead of fresh mozzarella.

Quick and Easy: With less than 30 minutes of prep and cooking time, this is the perfect snack for a last-minute appetizer or a savory craving.

Gluten-Free and Low-Carb: No breadcrumbs needed—this recipe is naturally keto-friendly while still being satisfyingly crunchy.

Versatile and Fun: Serve these as an appetizer, side dish, or snack with marinara sauce, ranch dressing, or homemade garlic aioli for dipping.

Ingredients

Onion: A large yellow or white onion works best here. Look for one with thick layers to create sturdy rings that can hold the mozzarella.

Mozzarella: String cheese sticks are ideal for this recipe—they fit easily inside the onion rings and melt evenly. Avoid fresh mozzarella, as it’s too moist and won’t hold its shape well.

Eggs: These act as a binding agent for the breading. Whisk them thoroughly for an even coating.

Almond Flour: This gives a light, crispy texture without the carbs. For extra crunch, combine it with crushed pork rinds.

Parmesan: A bit of grated Parmesan in the breading adds rich umami flavor and enhances the crispiness.

Spices: Garlic powder and smoked paprika add depth to the flavor, while a touch of salt and pepper brings everything together.

Avocado Oil: Perfect for frying, as it withstands high heat without breaking down or adding an overpowering flavor.

Step-by-Step Instructions

Save

Start by prepping the onion. Peel it, then slice it into thick rings, about ½ inch wide. Carefully separate the rings, keeping only the largest ones—these will hold the mozzarella.

Take the mozzarella sticks and cut them into pieces slightly shorter than the width of the onion rings. Place a piece of mozzarella inside each onion ring, ensuring it fits snugly. If the cheese is too long, trim it down to size.

Set up your breading station. In the first bowl, crack the eggs and whisk them until smooth. In a second bowl, mix the almond flour, grated Parmesan, garlic powder, smoked paprika, salt, and pepper. For extra crunch, add crushed pork rinds to a third bowl.

Coat each onion ring. First, dip it into the almond flour mixture, ensuring an even coating. Next, dip it into the beaten eggs, making sure the entire surface is covered. Finally, roll it in the crushed pork rinds (if using) or repeat the almond flour mixture. For an even crispier texture, repeat the egg and breading steps one more time.

Heat about ½ inch of avocado oil in a skillet over medium heat. Once the oil is hot, carefully place the rings in the pan and fry for 2-3 minutes on each side until golden brown. Fry in small batches to maintain the oil temperature and ensure even cooking.

Once done, transfer the rings to a paper towel-lined plate to absorb any excess oil. Serve immediately with marinara sauce or garlic aioli for dipping.
