Prep the carrots. Peel standard carrots and slice them into sticks or coins about 1/2 inch thick. If using baby carrots, cut any large ones in half lengthwise so they cook evenly.
Preheat the air fryer. Set it to 380°F (193°C) for 3 to 5 minutes.
A warm basket helps with quick browning.
Season. In a bowl, toss the carrots with 1 to 1.5 tablespoons oil, 1/2 to 3/4 teaspoon salt, and 1/4 teaspoon black pepper. Add 1/2 teaspoon garlic powder and 1/2 teaspoon paprika if you like. For a glaze, add 1 to 2 teaspoons honey or maple syrup.
Load the basket. Spread the carrots in a single layer with a bit of space between them.
If your air fryer is small, cook in two batches. Overcrowding leads to steaming instead of roasting.
Air fry. Cook at 380°F for 14 to 18 minutes, shaking the basket or stirring halfway through. Start checking at 12 minutes—thickness and air fryer models vary.
Check doneness. The carrots should be tender when pierced with a fork and lightly browned on the edges. If you want more color, add 2 to 3 minutes.
Finish and serve. Toss with a squeeze of fresh lemon juice and a sprinkle of herbs.
Taste and adjust salt. Serve warm.
