How to Make Keto Onion Rings

Step 1: Prepare the Onion

Peel and slice the onion into ½-inch thick rounds. Separate into rings and discard very small inner rings. Pat dry thoroughly—this helps the coating stick properly.

Step 2: Set Up Dredging Stations

Prepare three bowls:

Bowl 1 (Dry Mix):
Almond flour, coconut flour, smoked paprika, garlic powder, onion powder, baking powder, 1 tsp salt, and pepper.

Bowl 2 (Wet Mix):
Whisk eggs and heavy cream until smooth.

Bowl 3 (Extra Dry Mix):
Reserve ½ cup of the flour mixture separately to prevent clumping.

This double-dredging technique is the secret behind extra crispy Keto Onion Rings.

Step 3: Double Coat for Crispiness

Coat onion ring in Bowl 3 dry mix.
Dip into egg mixture.
Press firmly into main dry mix (Bowl 1) for a thick coating.

Place coated rings on a clean plate.

Step 4: Heat the Oil

Heat avocado oil in a heavy pot to 350°F (177°C). Maintaining temperature is crucial for perfect Keto Onion Rings.

Step 5: Fry to Golden Perfection

Fry 4–5 rings at a time for 2–3 minutes, flipping halfway. Remove once deep golden brown.

Step 6: Drain & Season

Transfer to a paper towel-lined plate. Sprinkle with remaining salt while hot.

Step 7: Serve Immediately

Serve your Keto Onion Rings hot for maximum crispiness.

Baking & Air Fryer Options

Oven Method:

Preheat oven to 425°F (220°C)
Spray breaded rings with oil
Bake 15–20 minutes, flipping halfway

Air Fryer Method:

Preheat to 400°F (200°C)
Spray basket and rings generously
Cook 8–10 minutes, flipping halfway

Both methods create delicious Keto Onion Rings, though frying delivers the crispiest texture.

Tips for Perfect Keto Onion Rings

Serve Immediately: Keto Onion Rings are crispiest fresh out of the fryer.

Flavor Variations

Spicy Version

Add ¼ tsp cayenne pepper for heat.

Cheesy Version

Mix grated Parmesan into the flour blend.

Nut-Free Option

Use crushed pork rinds instead of almond flour.

These variations make Keto Onion Rings customizable for any taste preference.

Storage & Reheating

Refrigerator: Store up to 3 days in airtight container.
Reheat: Air fry at 375°F for 3–5 minutes to restore crispiness.
