1. Prepare the Beef
- Slice the Beef:
- Slice the flank steak or sirloin thinly against the grain to ensure tenderness.
- Coat the Beef:
- Place the beef slices in a bowl and toss with cornstarch until evenly coated. This helps to create a crispy exterior when air fried.
2. Prepare the Sauce
- Mix the Sauce:
- In a small saucepan, combine the soy sauce, hoisin sauce, brown sugar, water, rice vinegar, minced garlic, minced ginger, and crushed red pepper flakes (if using).
- Cook the Sauce:
- Bring the mixture to a simmer over medium heat. Cook for 3-4 minutes until the sauce slightly thickens. Remove from heat and set aside.
3. Air Fry the Beef
- Preheat the Air Fryer:
- Preheat your air fryer to 380°F (193°C) for about 3-5 minutes.
- Arrange the Beef:
- Lightly coat the air fryer basket with cooking spray. Arrange the coated beef slices in a single layer in the basket. Avoid overcrowding to ensure even cooking. You may need to cook in batches depending on the size of your air fryer.
- Cook:
- Air fry the beef at 380°F (193°C) for 8-10 minutes, shaking the basket or flipping the beef halfway through cooking. The beef should be crispy and cooked through.
4. Combine and Serve
- Toss in Sauce:
- Transfer the cooked beef to a large bowl. Pour the prepared sauce over the beef and toss until evenly coated.
- Garnish (Optional):
- Garnish with sesame seeds and chopped green onions if desired.
- Serve:
- Serve the Mongolian beef over steamed rice or noodles. Enjoy it with a side of vegetables for a complete meal.
Tips for Success
- Slice Thinly: Thin slices of beef ensure a crispy exterior and tender interior. Freeze the beef slightly before slicing to make it easier to cut thinly.
- Avoid Overcrowding: Arrange the beef slices in a single layer in the air fryer basket to ensure they cook evenly and get crispy.
- Adjust Time: Cooking times may vary based on the size of the beef slices and the model of your air fryer, so check for doneness and adjust as needed.
