Crispy Onion Rings
High-protein, low-carb onion rings with a crunchy coating and creamy dip — ready in 30 minutes
These crispy onion rings are golden, crunchy, and much higher in protein than classic fried rings. Thick onion slices get a protein-boosted breading, then bake or air-fry until crisp. Every serving delivers 18 g of protein and only 7 g net carbs.
Low-carb, high-protein, and perfect as a snack, side, or appetizer with a simple dip.
Why you’ll love these onion rings
- 18g protein per serving — a high-protein snack or side
- Only 7g net carbs
- Crispy coating without a heavy flour batter
- Ready in about 30 minutes
- Air-fryer or oven friendly
- Great with ranch, garlic dip, or sugar-free ketchup
Health notes
- High protein: Protein powder, Parmesan, and egg help the coating stick and boost macros.
- Low carb: Almond flour and pork rinds or Parmesan replace regular breadcrumbs.
- Sugar-free: No sweetened coatings or dips needed.
- Lighter method: Air-frying or baking keeps them crispy without deep-frying.
Key element — dry the onions well
Pat the onion rings dry before breading. Extra moisture makes the coating slide off and turn soggy.
Ingredients
Onion rings
- 2 large onions, sliced into ½-inch rings
- 2 large eggs
- 2 Tbsp heavy cream or unsweetened almond milk
- ½ cup almond flour
- ⅓ cup unflavored or savory protein powder
- ½ cup crushed pork rinds or extra Parmesan
- ⅓ cup grated Parmesan
- 1 tsp paprika
- ½ tsp garlic powder
- ½ tsp salt
- ¼ tsp black pepper
- Oil spray for cooking
Dip
- ½ cup sour cream or Greek yogurt
- 1 Tbsp mayonnaise
- 1 tsp lemon juice or vinegar
- 1 Tbsp chopped chives
- Salt and pepper to taste
Swaps
- No pork rinds: Use extra Parmesan and almond flour.
- Spicy: Add cayenne or chili powder to the coating.
- Dairy-free: Skip Parmesan and use extra almond flour plus seasoning.
- Oven only: Bake on a rack so air can circulate under the rings.
Instructions
| 1 | Prep the onions. Slice the onions into thick rings and separate them. Pat very dry with paper towels. |
| 2 | Set up the coating. Whisk the eggs with cream. In another bowl, mix almond flour, protein powder, crushed pork rinds, Parmesan, paprika, garlic powder, salt, and pepper. |
| 3 | Bread the rings. Dip each onion ring in the egg mixture, then press into the dry coating so it sticks on all sides. Place on a rack or lined tray. |
| 4 | Cook. Air-fry at 390°F (200°C) for 8–12 minutes, flipping once, until golden and crisp. Or bake at 425°F (220°C) for 14–18 minutes on a rack, flipping halfway. Spray lightly with oil before cooking. |
| 5 | Make the dip and serve. Stir together sour cream, mayonnaise, lemon juice, chives, salt, and pepper. Serve the onion rings immediately with the dip. |
Pro tips
- Pat the onions dry or the breading will slip off.
- Press the coating on firmly so it stays crunchy.
- Don’t crowd the air fryer or oven rack — work in batches.
- A light oil spray helps the coating brown.
- These are best eaten right away while the crust is still crisp.
