Ingredients

(Tip: You can find the complete list of ingredients and their measurements in the recipe card below.)

Onions are the heart of the recipe and become sweet and tender once baked. Large white or yellow onions work best for thick onion rings.

Almond flour creates the crispy low-carb coating while adding a slightly nutty flavor.

Parmesan cheese adds savory richness and helps the coating become extra crispy in the oven.

Eggs help the coating stick to the onion rings while creating a golden baked texture.

Garlic powder adds savory flavor and enhances the overall seasoning.

Paprika gives the onion rings warm flavor and beautiful golden color.

Italian seasoning adds extra depth and savory herb flavor to the crispy coating.

Salt and black pepper balance the flavors and enhance the sweetness of the onions.

Olive oil spray helps the onion rings crisp up beautifully during baking. I once used avocado oil spray instead, and the onion rings turned out incredibly crispy and flavorful.

Directions

Preheat the oven to 425°F and line a baking sheet with parchment paper.

Slice the onions into thick rings and carefully separate them into individual onion rings.

In one bowl, whisk the eggs until smooth.

In another bowl, combine almond flour, Parmesan cheese, garlic powder, paprika, Italian seasoning, salt, and black pepper.

Dip each onion ring into the egg mixture, coating it fully.

Transfer the onion ring to the almond flour mixture and coat evenly on all sides.

Place the coated onion rings onto the prepared baking sheet in a single layer.

Lightly spray the onion rings with olive oil spray to help them crisp while baking.

Bake for about 18 to 22 minutes, flipping halfway through, until golden brown and crispy.

Allow the onion rings to cool slightly before serving with your favorite low-carb dipping sauce.

Servings and timing

This recipe makes approximately 4 servings.

Preparation time: 15 minutes
Cooking time: 22 minutes
Total time: About 37 minutes

Storage/reheating

Store leftover onion rings in an airtight container in the refrigerator for up to 3 days.

To reheat, place them in the oven or air fryer until crispy again and heated through.

Avoid microwaving if possible because it may soften the crispy coating.

For best texture, serve the onion rings fresh and hot right after baking.

Variations and Customizations

One of the best things about low-carb baked onion rings is how easy they are to customize with different seasonings and coatings.

For extra spice, add cayenne pepper or chili powder to the coating mixture. The slight heat pairs beautifully with the sweet onions.

If you enjoy cheesy flavor, increase the Parmesan cheese or mix in shredded cheddar for a richer coating. I once added smoked paprika and extra Parmesan, and the flavor became even more savory and delicious.

You can also use pork rind crumbs instead of almond flour for an even crispier keto coating.

For a stronger herb flavor, add dried oregano, thyme, or parsley to the breading mixture.

Another delicious option is serving the onion rings with different low-carb dipping sauces like garlic aioli, spicy mayo, ranch dressing, or sugar-free barbecue sauce.

If you prefer thinner onion rings, slice the onions thinner for extra crunch and quicker baking time.

You can also make this recipe in the air fryer for even crispier texture with less cooking time.

For a fun variation, try using the same coating method with zucchini slices, mushrooms, or pickle chips for other low-carb crispy snacks.
