Wash the Roma tomatoes and pat them dry.

Slice the tomatoes in half lengthwise. For larger tomatoes, you can consider quartering them.

In a bowl, toss the tomato halves with a light drizzle of olive oil. Ensure each piece is lightly coated.

Season with salt and freshly ground black pepper. You can also add herbs like dried basil, oregano, or thyme for extra flavor.

Preheat the air fryer to 375°F (190°C). This step may vary depending on your air fryer model.

Arrange the tomato halves in the air fryer basket in a single layer, cut side up. Avoid overcrowding to ensure even cooking.

Roast the tomatoes in the air fryer for about 15-20 minutes. The exact time can depend on the size of the tomatoes and the desired level of roasting.

Halfway through the cooking time, you can gently flip the tomatoes for even roasting, although this is optional.

The tomatoes are done when they are tender and the edges start to brown slightly.

If you prefer a more charred or dehydrated texture, you can extend the cooking time by a few minutes, monitoring closely to avoid burning.
