• 2 tablespoons brown sugar

How to Make Air Fryer Mongolian Beef Steak Strips
Step 1: Slice the Beef Properly
Slice steak thinly against the grain. Thin strips cook quickly and stay tender.
Step 2: Marinate
In a bowl, mix soy sauce, hoisin, brown sugar, ginger, garlic, sesame oil, pepper, and cornstarch. Toss beef strips until fully coated. Let marinate for at least 20 minutes (or up to 2 hours for deeper flavor).
The cornstarch helps create that slightly crispy coating and thickened glaze.
Step 3: Preheat the Air Fryer
Preheat to 400°F (200°C) for 3–5 minutes.
Step 4: Air Fry
Place steak strips in a single layer in the basket. Avoid overcrowding. Cook for 7–9 minutes, shaking halfway through, until edges caramelize and beef is cooked through.
If you prefer extra char, cook an additional 1–2 minutes.
Step 5: Finish and Garnish
Sprinkle with sliced green onions and optional red pepper flakes. Serve immediately while glossy and hot.
Pro Tips for Perfect Results
• Slice against the grain for tenderness
• Don’t overcrowd the basket
• Pat beef slightly dry if marinade is too wet
• Cook in batches if necessary
• For extra sauce, simmer leftover marinade in a pan until thickened
