Pro Tips For Cooking Peppers and Onions In Air Fryer

Cooking peppers and onions in an air fryer can be a delightful experience, and with these pro tips, you can ensure they turn out perfectly every time:

  • Even Slicing: Cut the peppers and onions into uniform sizes. This promotes even cooking, ensuring that all pieces are perfectly tender and slightly charred at the same time.
  • Light Oil Coating: Toss the vegetables in just enough oil to coat them lightly. You can use olive, avocado, vegetable, or coconut oil. This helps in achieving a good roast without making them greasy.
  • Seasoning Balance: Be careful with the amount of seasoning. Too much can overpower the natural flavors of the vegetables, while too little can leave them bland. Taste and adjust as needed.
  • Preheat the Air Fryer: Always preheat your air fryer before adding the vegetables. This ensures a quick start to cooking and helps achieve that nice roast on the edges.

  • Shake or Stir: Halfway through the cooking time, shake the basket or use a spatula to stir the vegetables. This ensures that all sides get evenly cooked and charred.
  • Cooking Time Adjustment: Depending on your air fryer model and the amount of vegetables, cooking times can vary. Keep an eye on them and adjust the time as needed.
  • Adding Freshness: After cooking, add a splash of fresh lemon juice or vinegar for a bit of acidity, which can brighten the flavors.
  • Utilizing Leftovers: Any leftovers can be used in various dishes like omelets, sandwiches, or salads, adding flavor and nutrition.
  • Resting Time: The vegetables rest for a minute or two after cooking. This allows the residual heat to finish cooking them to perfection.

Following these tips, you can make deliciously roasted peppers and onions in your air fryer, perfect as a side dish, fajita filling, or a flavorful addition to a simple meal.
