How To Cook Steak Fajitas In The Air Fryer

Preparing Air Fryer Fajitas

Preheat your air fryer to 200C / 400F for 5 minutes.

Cut the beef into even-sized cubes.

Slice the onions and peppers into strips.

Place the sliced vegetables in a bowl, drizzle with olive oil, add the fajita seasoning and set aside.

Air Frying The Beef

Once the air fryer is preheated, place the beef steak in a single layer in the air fryer basket.

Air fry at 200C / 400F for approximately 8-10 minutes, or until the beef reaches your desired level of doneness. Remember to turn halfway through for even cooking.

Adding the Vegetables

Remove the beef strips from the air fryer and set aside.

Add the sliced onions and bell peppers to the air fryer basket.

Cook the vegetables for 4-6 minutes, stirring occasionally, until they are tender and slightly charred.

Assembling the Fajitas

Warm up your tortillas. (I heat mine in the microwave for a minute or two depending on the quantity).

Place a generous amount of the cooked beef, sautéed onions, and bell peppers onto each tortilla.

Add any optional toppings of your choice. eg: salsa, guacamole or sour cream.

Roll up the crispy tortillas and serve immediately.

Storing Steak Fajita Filling

When it comes to storing beef fajita filling, you want to make sure you preserve all that delicious flavour and keep your leftovers fresh.

If you plan to use the leftover fajita filling within a couple of days refrigerate it.

Let the mix cool completely and store it in an airtight container.

Freezing Leftover Fajita Filling

  1. If you plan on storing your beef fajita filling for an extended period, freezing is the answer. It helps preserve the flavours and textures.
  2. Allow your beef fajitas mix to cool down to room temperature before storing. This helps prevent condensation buildup, which can make the meat soggy.
  3. Divide your beef fajitas into individual portions or servings. This makes it easier to reheat what you need and prevents unnecessary waste.
  4. Place each portion of beef fajitas in airtight containers or resealable freezer bags. Remove as much air as possible to maintain freshness and prevent freezer burn.
  5. Label and date: Don’t forget to label your containers with the contents and the date of storage. Store in the freezer for up to 3 months.

How To Reheat Air Fryer Fajitas

To reheat any fajita filling leftovers, air fry at 180C / 360F for 5-6 minutes or until heated through.
