The air fryer solves this by circulating hot air at high speed, creating a crispy exterior while locking in moisture. In just 15 minutes, you get tender, flavorful strips that beat any takeout.

Why You'll Love This Recipe
About the Ingredients
1 lb (450g) chicken tenderloins, about 8-10 pieces
Tenderloins are the lean strip under the breast. If you can't find them, cut chicken breasts into 1-inch strips. Pat dry before marinating for best adhesion.
1/2 cup (120ml) buttermilk
Buttermilk's acidity tenderizes the chicken. No buttermilk? Mix 1/2 cup milk with 1.5 tsp lemon juice and let sit 5 minutes.
1 tsp garlic powder
Adds savory depth. Feel free to swap for onion powder or a pinch of cayenne for heat.
1 tsp paprika
Smoked paprika adds a subtle smokiness. Sweet paprika works too, but skip if you're avoiding spice.
1/2 tsp salt
Enhances flavor. Use kosher salt if you have it; reduce to 1/4 tsp if using fine table salt.
1/4 tsp black pepper
Freshly ground is best. Pre-ground works in a pinch.
1/2 cup (60g) cornstarch
Cornstarch creates a light, crispy crust. Substitute with potato starch or arrowroot powder.
1 cup (100g) panko breadcrumbs
Panko stays crunchier than regular breadcrumbs. For a gluten-free option, use crushed pork rinds or gluten-free panko.
2 large eggs, beaten
Eggs act as the glue for the coating. For an egg-free version, use a slurry of 1 tbsp cornstarch + 3 tbsp water.
Cooking spray (olive oil or avocado oil)
Use a neutral oil spray to help browning. You can also brush with melted butter for extra richness.
Tips & Tricks
Don't skip the buttermilk marinade
It's the key to tender, juicy chicken. Even 15 minutes helps, but 30 is better.
Pat the chicken dry before coating
Excess moisture makes the coating soggy. Use paper towels to remove surface liquid.
Don't overcrowd the basket
Leave space between pieces so hot air circulates. Cook in batches if needed—this ensures even crispiness.
Pro Tips
Step-by-Step Instructions
1. Marinate the chicken
In a bowl, combine chicken tenderloins with buttermilk, garlic powder, paprika, salt, and pepper. Cover and refrigerate for at least 15 minutes, or up to 2 hours. This step tenderizes the meat and infuses flavor.
2. Set up coating station
Place cornstarch in one shallow dish, beaten eggs in another, and panko in a third. Line a plate with parchment paper for the coated pieces.
3. Coat each tenderloin
Take a tenderloin from the marinade, letting excess drip off. Dredge in cornstarch, dip in egg, then press into panko, ensuring an even coat. Place on the prepared plate. Repeat with all pieces.
4. Preheat air fryer
Set your air fryer to 400°F (200°C) and let it preheat for 3 minutes. Preheating ensures a hot start for maximum crispiness.
5. Arrange in basket
Lightly spray the air fryer basket with cooking spray. Place the coated tenderloins in a single layer, leaving space between each piece. You may need to cook in batches depending on your fryer size.
6. Spray with oil
Lightly spray the tops of the chicken with cooking spray. This helps the coating turn golden and crispy.
7. Air fry the chicken
Cook at 400°F (200°C) for 8 minutes. Then flip each piece and cook for another 4-6 minutes, until the internal temperature reaches 165°F (74°C) and the coating is golden brown and crispy.
8. Rest and serve
Remove the chicken from the air fryer and let rest for 2 minutes on a wire rack. This keeps the crust crisp. Serve hot with your favorite dipping sauce.
Delicious Variations
Spicy
Add 1 tsp chili powder and 1/2 tsp cayenne to the marinade, or toss cooked chicken in buffalo sauce.
Parmesan
Mix 1/4 cup grated Parmesan cheese into the panko for a savory, nutty crust.
Lemon Herb
Add 1 tbsp fresh lemon zest and 1 tbsp chopped parsley to the marinade for a bright, fresh flavor.
How to Store Chicken Tenderloin In Air Fryer
Refrigerator
Store leftovers in an airtight container for up to 3 days. Place a paper towel in the container to absorb moisture and keep the coating crisp.
Freezer
Freeze cooked chicken in a single layer on a baking sheet, then transfer to a freezer bag for up to 2 months. Thaw overnight in the fridge before reheating.
Reheating
Reheat in the air fryer at 375°F (190°C) for 3-4 minutes until hot and crispy. Avoid microwaving, which makes the coating soggy.
Frequently Asked Questions
Q: How long do you cook chicken tenderloins in an air fryer?
Cook at 400°F (200°C) for 12-14 minutes total, flipping halfway. The internal temperature should reach 165°F (74°C) for safety.
Q: Do you need to preheat an air fryer?
Yes, preheating for 3 minutes ensures even cooking and better crisping. Most air fryers have a preheat function, or you can just run it empty for 3 minutes.
Q: Can I use frozen chicken tenderloins?
Yes, but increase cooking time by 5-7 minutes and make sure the internal temperature hits 165°F (74°C). Do not thaw before coating; pat dry and coat as usual.
Q: Why is my chicken not crispy?
The most common reasons are overcrowding the basket, not using enough oil spray, or skipping the cornstarch. Ensure pieces are spaced apart and spray generously.
