Ingredients

• 2 medium yellow onions, thinly sliced
• ½ cup almond flour
• ¼ cup grated Parmesan cheese
• 1 large egg
• 1 tablespoon heavy cream
• ½ teaspoon garlic powder
• ½ teaspoon paprika
• Salt and black pepper to taste
• Cooking spray or olive oil spray

Ingredient Notes

Onions: Yellow onions provide the perfect balance of sweetness and savory flavor once cooked.

Almond Flour: Replaces traditional flour to keep the recipe low-carb and keto-friendly.

Parmesan Cheese: Adds extra flavor and helps create a crisp golden crust.

Egg & Cream: These help the coating stick to the onion slices.

The combination of almond flour and Parmesan creates a crunchy texture that mimics traditional fried onions beautifully.

Step-by-Step Instructions

Step 1: Slice the Onions

Peel the onions and slice them into thin rings or half-moons. Try to keep the slices evenly sized so they cook at the same rate.

Separate the onion layers gently with your fingers.

Step 2: Prepare the Egg Mixture

In a small bowl, whisk together the egg and heavy cream until smooth.

This mixture will help the low-carb coating stick to the onions.

Step 3: Mix the Coating

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

Stir well so the seasoning is evenly distributed.

Step 4: Coat the Onion Slices

Dip onion slices into the egg mixture first, then toss them in the almond flour mixture.

Make sure each piece is evenly coated for the best crispy texture.

Step 5: Prepare the Air Fryer

Preheat your air fryer to 375°F (190°C) for about 3 minutes.

Lightly spray the air fryer basket with cooking spray to prevent sticking.

Step 6: Air Fry Until Crispy

Place the coated onion slices in the air fryer basket in a single layer. Avoid overcrowding so the air circulates properly.

Lightly spray the tops with cooking spray.

Air fry for 8–10 minutes, shaking the basket halfway through. The onions should turn golden brown and crispy.

Step 7: Cool and Crisp

Remove the onions from the air fryer and let them cool slightly. They will become even crispier as they cool.

Serve immediately for the best texture.

Serving Suggestion

These Keto Air Fryer Crispy Fried Onions can be enjoyed in many delicious ways:

• Sprinkle over keto burgers or sandwiches
• Add to salads for extra crunch
• Top casseroles or keto green bean dishes
• Serve as a snack with keto dipping sauces
• Use as a crunchy topping for soups

They’re especially delicious paired with garlic aioli or spicy mayo.

Pro Tips & Variations

For extra crunch, add a tablespoon of crushed pork rinds to the coating mixture. If you like a spicy kick, mix in cayenne pepper or chili powder. For a smoky flavor, try smoked paprika instead of regular paprika.

Make sure the onions are sliced thinly and evenly for consistent crisping. Always cook them in a single layer in the air fryer to avoid steaming. If cooking a large batch, work in multiple batches for the best results.

Storage Information

• Refrigerator: Store in an airtight container up to 2 days
• Freezer: Not recommended (they lose crispiness)
• Reheating: Reheat in air fryer at 350°F for 2–3 minutes

For the best taste and crunch, enjoy them fresh.
