How to Make Keto Air Fryer Mongolian Beef

Step 1: Preheat Your Air Fryer

Start by preheating the air fryer to 400 degrees. This step is crucial as it ensures that your beef and green beans cook evenly and get that delightful crispiness.

Step 2: Toss the Beef and Green Beans

In a bowl, toss the steak strips and fresh green beans together with olive oil and sesame oil. This not only adds flavor but also helps them achieve that perfect golden-brown finish while cooking.

Step 3: Cook in the Air Fryer

Place the coated steak and green beans in the air fryer basket. Cook them for about 10-12 minutes, stirring halfway through. This allows everything to cook evenly while giving those delicious bits time to develop.

Step 4: Prepare the Sauce

While your beef and green beans are cooking away, grab a saucepan. Heat together soy sauce, water, Swerve brown sugar substitute, ginger paste, minced garlic, and season with salt and pepper. Simmer until thickened—this will create an incredibly rich sauce that ties all the flavors together beautifully!

Step 5: Combine Everything

Once your air-fried beef and green beans are ready, toss them in that glorious sauce right before serving. Garnish with chopped green onions for an added burst of freshness. Enjoy every mouthful of this delightful dish!

Pro Tips for Making Keto Air Fryer Mongolian Beef

Making the perfect Keto Air Fryer Mongolian Beef is a breeze with these helpful tips!

  • Choose the Right Cut: Opt for flank or sirloin steak as they are lean cuts that become tender and flavorful when cooked quickly in the air fryer.
  • Don’t Overcrowd the Basket: Cooking in batches ensures even cooking and allows the meat to get that nice, crispy exterior without steaming.
  • Marinate for Flavor: If time permits, marinating the steak for 30 minutes before cooking can boost flavor significantly and enhance tenderness.
  • Adjust Cooking Time: Keep an eye on your beef as cooking times can vary based on thickness; using a meat thermometer can help ensure perfect doneness.
  • Let It Rest: Allowing the cooked beef to rest for a few minutes before serving will help retain its juices, making each bite more succulent.
