Preheat the air fryer to 350°F.
Place the peeled, angled-sliced carrots (1½–2" long slices) in a large bowl.
Add 2 tablespoons olive oil, 1/2 tablespoon low-sodium soy sauce or coconut aminos, 1/3 teaspoon garlic powder, 1/4 teaspoon smoked paprika, salt and black pepper to taste, and 1–2 tablespoons grated parmesan cheese or vegan parmesan cheese to the bowl. Toss until the carrots are evenly coated.
Arrange the carrots in a single layer in the air fryer basket, working in batches if necessary to avoid overcrowding.
Air fry at 350°F for 20–25 minutes, shaking or tossing the basket about halfway through (around 10–12 minutes), until the carrots are tender when pierced with a fork and lightly browned at the edges.
Transfer the cooked carrots to a serving platter. Tear or chop the 2–3 fresh basil leaves and sprinkle them over the carrots, then finish with chopped pistachios as a garnish.
