20-Minute Keto Bang Bang Chicken (Extra Crispy & Air Fryer!)

This keto bang bang chicken is fast, crispy, and coated in a creamy, spicy-sweet sauce that tastes just like takeout. The air fryer does the heavy lifting, so dinner hits the table in about 20 minutes.

You will get juicy bites with a shatter-crisp crust and a sauce that clings to every piece. It is weeknight-friendly and completely low carb.

Why This Keto Bang Bang Chicken Works

Traditional bang bang chicken relies on cornstarch or flour. Here we use a mix of crushed pork rinds, almond flour, and Parmesan for a golden, ultra-crispy coating that stays low carb. The air fryer keeps the inside juicy while crisping the outside fast.

The sauce is creamy and balanced: a little heat, a little tang, and just the right hint of sweetness using sugar-free condiments. Toss or drizzle right before serving so the crunch stays perfect.

Ingredients You’ll Need

Simple pantry staples build big flavor. The coating is crunchy without carbs, and the sauce mixes up in one bowl.

Chicken

• 1 1/2 lb boneless skinless chicken thighs or breasts, cut into 1-inch pieces
• 1 large egg, beaten
• 1 tbsp mayonnaise, stirred into egg
• 1 tsp kosher salt
• 1/2 tsp black pepper
• 1/2 tsp garlic powder
• 1/2 tsp smoked paprika

Crispy Coating

• 1 cup crushed pork rinds, very fine crumbs
• 1/2 cup blanched almond flour
• 1/4 cup finely grated Parmesan cheese
• avocado oil spray, for air fryer basket and tops

Bang Bang Sauce

• 1/2 cup mayonnaise
• 2 tbsp sugar-free sweet chili sauce
• 1 tbsp sriracha, or to taste
• 2 tsp rice vinegar, or lime juice
• 1 tsp powdered allulose or erythritol, optional, to taste
• 1 small garlic clove, finely grated

Garnish

• 2 tbsp sliced green onions
• 1 tsp toasted sesame seeds, optional

How to Make It

Preheat, coat, air fry until crisp, then toss in sauce and serve hot.

1. Preheat the air fryer to 400°F (200°C) for 3 minutes. In a small bowl, whisk together all sauce ingredients and set aside.
2. Pat chicken dry with paper towels. In a medium bowl, whisk egg and 1 tablespoon mayo, then stir in salt, pepper, garlic powder, and smoked paprika. Add chicken and toss to coat evenly.
3. In a shallow dish, combine crushed pork rinds, almond flour, and Parmesan. Mix well so crumbs are fine and uniform.
4. Working in batches, dredge chicken pieces in the crumb mixture, pressing to adhere. Shake off excess crumbs.
5. Lightly spray the air fryer basket with avocado oil. Arrange chicken in a single layer without touching; spray the tops lightly.
6. Air fry for 8 to 10 minutes, flipping at the 5-minute mark and spraying again, until the coating is deep golden and the centers reach 165°F (74°C). Repeat with remaining batches.
7. Transfer hot chicken to a bowl and toss with half the bang bang sauce, or drizzle to keep extra crisp. Garnish with green onions and sesame seeds and serve with remaining sauce.

Storage, Make-Ahead, and Reheating

Store cooked chicken and sauce separately in airtight containers for up to 3 days. The coating keeps its crunch better if you sauce it right before serving. If you need to prep ahead, bread the chicken and refrigerate it on a rack for up to 12 hours; this actually helps the coating adhere and dry slightly for extra crispiness.

Reheat chicken in the air fryer at 375°F (190°C) for 3 to 5 minutes until hot and re-crisped. Then toss with fresh sauce. For meal-prep inspo and planning help, see this simple keto meal prep guide for beginners.

Common Mistakes to Avoid

• Overcrowding the basket: Air needs room to circulate. Cook in batches so the pieces crisp instead of steam.
• Skipping the oil spray: A light mist on the basket and tops promotes even browning and that signature crunch.
• Coarse crumbs: Finely crush pork rinds so the coating adheres well and does not fall off.
• Saucing too early: Tossing hot chicken in sauce too soon can soften the crust. Sauce right before serving.
• Uneven pieces: Cut chicken into uniform 1-inch chunks so they cook through at the same time.

Easy Variations and Substitutions

• Dairy-free: Omit Parmesan and add 2 extra tablespoons of almond flour. The pork rinds still keep it crisp.
• Nut-free: Skip almond flour and use all crushed pork rinds with Parmesan for structure.
• Milder sauce: Reduce sriracha to 1 teaspoon and add more mayo to taste.
• No sweet chili sauce: Use 1 tablespoon sriracha, 1 to 2 teaspoons powdered allulose, and 2 teaspoons rice vinegar in the sauce.
• Oven method: Bake on a wire rack set over a sheet pan at 425°F (220°C) for 14 to 16 minutes, flipping once, then sauce.
• Shrimp swap: Use peeled, deveined shrimp. Air fry at 390°F (200°C) for 5 to 7 minutes.

Keto Bang Bang Chicken FAQ

Can I bake this instead of using an air fryer?

Yes. Arrange breaded chicken on a greased wire rack over a sheet pan and bake at 425°F (220°C) for 14 to 16 minutes, flipping once, until 165°F and golden. Finish with sauce right before serving.

Is chicken breast or thigh better for bang bang chicken?

Both work. Thighs are a bit more forgiving and stay juicier. If you use breast, cut the pieces evenly and do not overcook. Pull at 165°F and rest 2 minutes.

How can I make the sauce less spicy or sweeter without sugar?

Use more mayo and reduce sriracha to taste. For sweetness, add 1 to 2 teaspoons powdered allulose or erythritol. Stir, taste, and adjust the vinegar for balance.

My coating falls off. What am I doing wrong?

Pat the chicken very dry, use a thin egg wash, and press firmly into fine crumbs. Chill the breaded pieces 10 minutes before cooking and avoid overcrowding the basket.

Can I toss the chicken fully in sauce?

Absolutely. For maximum crunch, drizzle or toss with only half the sauce and serve the rest on the side. The coating will soften slightly if fully sauced.
