Preheat the air fryer to 400°F (200°C) for a few minutes while preparing the ingredients.
Wash the potatoes thoroughly and cut them into bite-sized cubes or wedges.
Place the potatoes in a mixing bowl and drizzle them with olive oil. Add the desired seasonings and toss until the potatoes are evenly coated.
Slice the bell peppers into thin strips and the onion into thin strips or rings.
Add the sliced bell peppers and onions to the bowl with the seasoned potatoes. Gently toss to combine, ensuring even distribution of the vegetables.
Transfer the potato, pepper, and onion mixture to the preheated air fryer basket, spreading them out in a single layer to avoid overlapping.
Cook the home fries in the air fryer for approximately 15-20 minutes. Shake the basket or toss the potatoes halfway through the cooking time.
Check the home fries for doneness. They should be golden brown and crispy on the outside with a tender interior. Cook for an additional few minutes if needed.
Once cooked to perfection, transfer the home fries to a serving dish.
Serve and enjoy as a flavorful side dish with breakfast, lunch, or dinner.
