Crispy Air Fryer Beef

Equipment

• Air Fryer: 5-quart capacity or larger (basket or oven style)
• Sharp Chef’s Knife: For precision slicing against the grain
• Large Mixing Bowls: 2 (one for marinating, one for sauce)
• Shallow Dish or Rimmed Baking Sheet: For coating the beef evenly
• High-Smoke Point Cooking Oil Spray: Avocado oil or canola oil spray (avoid aerosol propellants)
• Tongs: Heat-resistant silicone or metal tongs

Ingredients

Beef & Marinade

• 1.5 lbs (700g) flank steak (substitute: sirloin or skirt steak), trimmed of excess fat
• 1 tbsp low-sodium soy sauce
• 1 tbsp shaoxing wine (or dry sherry)
• 1 tsp toasted sesame oil
• 1/2 tsp ground white pepper
• 1/4 tsp baking soda (essential for tenderizing)
• 1 large egg white , lightly beaten

Crispy Dredge

• 1/2 cup cornstarch (substitute: potato starch or arrowroot powder)
• 2 tbsp all-purpose flour (or rice flour for extra crunch)
• 1/2 tsp garlic powder
• 1/2 tsp salt
• High-heat cooking spray (avocado oil preferred)

Sweet & Spicy Glaze

• 3 tbsp low-sodium soy sauce
• 2 tbsp sweet chili sauce
• 2 tbsp honey (substitute: brown sugar or keto maple syrup)
• 1 tbsp rice vinegar
• 1 tbsp sriracha (adjust for personal heat preference)
• 3 cloves garlic , finely minced
• 1 tbsp fresh ginger , finely grated
• 1 tbsp water mixed with 1 tsp cornstarch (slurry)

Garnish

• 2 scallions (green onions) , thinly sliced on the bias
• 1 tbsp toasted sesame seeds
• 1 red chili , thinly sliced (optional)

Instructions

Step 1: Prep and Slice the Steak

1. Place the steak in the freezer for 15 to 20 minutes prior to prepping. Chilling firms the muscle fibers, making thin cuts effortless.
2. Locate the direction of the grain (the visible parallel muscle lines).
3. Using a sharp chef’s knife, slice the beef across the grain into uniform strips approximately 1/4-inch thick and 2 to 3 inches long . Slicing against the grain breaks down tough muscle strands, ensuring tenderness.

Step 2: Marinate and Velvet

1. In a medium bowl, whisk together the soy sauce, shaoxing wine, sesame oil, white pepper, baking soda, and beaten egg white.
2. Add the beef strips to the bowl. Massage the liquid into the beef with your hands until fully absorbed.
3. Let sit at room temperature for 15 minutes (or cover and refrigerate up to 4 hours). The baking soda tenderizes the meat through an alkaline reaction (velveting), preventing toughness under high air fryer heat.

Step 3: Dredge the Beef

1. In a shallow rimmed dish, whisk together the cornstarch, flour, garlic powder, and salt.
2. Separate the beef strips and drop them into the starch mixture in small handfuls.
3. Toss thoroughly, ensuring every single strip is completely coated and no wet spots remain. Shake each piece individually to dislodge excess starch. Excess dry powder can burn in the air fryer, while clumping prevents a shatteringly crisp texture.
4. Transfer coated strips onto a wire rack or clean tray.

Step 4: Air Fry to Crispy Perfection

1. Preheat your air fryer to 400°F (200°C) for 5 minutes . Preheating is crucial to seal the crust immediately upon contact.
2. Lightly coat the bottom of the air fryer basket with avocado oil spray.
3. Arrange the beef strips in a single layer with at least 1/4-inch space between pieces. Do not overcrowd or stack the beef. Work in two to three batches depending on the size of your machine.
4. Generously spray the top of the beef with avocado oil spray until no dry, powdery white spots remain.
5. Cook at 400°F (200°C) for 5 minutes .
6. Pull out the basket, flip the strips with tongs, lightly spray any dry spots on the reverse side, and cook for an additional 4 to 6 minutes until dark golden, rigid, and audibly crunchy when tapped.
7. Transfer the cooked batch to a wire cooling rack and repeat with the remaining beef.

Step 5: Sauce and Glaze

1. While the last batch is in the air fryer, set a large skillet or wok over medium heat.
2. Add 1 teaspoon of oil, then stir-fry the minced garlic and grated ginger for 30 seconds until fragrant.
3. Pour in the soy sauce, sweet chili sauce, honey, rice vinegar, and sriracha. Bring to a rapid simmer for 1 minute.
4. Stir in the cornstarch slurry. Cook for 30 to 45 seconds until the sauce turns glossy and thick enough to coat the back of a spoon.
5. Remove the skillet from heat immediately.
6. Add the crispy beef strips directly into the skillet. Toss quickly and vigorously for 15 to 20 seconds until the beef is lightly glazed. Do not leave the beef simmering in the sauce, or the crust will absorb the moisture and soften.
