Preheat the air fryer: Set it to 375°F (190°C) for 3–5 minutes.
A preheated basket helps the egg set quickly and evenly.
Prep the avocado: Slice the avocado lengthwise and remove the pit. Scoop out a little extra flesh from each half to make a slightly larger well so the egg fits. Save the extra avocado for topping or another use.
Stabilize the halves: Tear a small piece of foil and crumple it into a ring for each avocado half, or use a small ramekin.
This keeps the avocado level so the egg doesn’t spill.
Oil and season: Brush or spray the cut sides and wells with olive oil. Season lightly with salt and pepper. This helps the edges brown and adds flavor.
Add the egg: Crack each egg into a small bowl first.
Then gently pour into the avocado well. If your eggs are large, let a bit of the white remain in the bowl so the well doesn’t overflow. Sprinkle with any additional seasonings.
Air fry: Place the avocado halves (on their foil rings or in ramekins) into the basket.
Cook at 375°F (190°C) for 8–12 minutes, depending on how runny you like the yolk and the size of your eggs. Start checking at 8 minutes. The whites should be set; the yolk can be soft or jammy.
Finish and serve: Carefully remove from the air fryer.
Add a squeeze of lemon or lime if you like. Top with herbs, cheese, bacon, or hot sauce. Serve immediately with toast, greens, or on its own.
