Cook the rice: If you haven’t already, start your rice so it’s ready when the salmon is done. Fluff and keep warm.
Preheat the air fryer: Set to 400°F (200°C) for 3–5 minutes. A hot basket helps the salmon sear.
Prep the salmon: Pat salmon dry with paper towels.
Rub with oil, then season with salt, pepper, and garlic powder.
Air-fry the salmon: Place portions in a single layer, skin-side down if using skin-on. Air-fry 7–10 minutes, depending on thickness and your preferred doneness. Aim for an internal temp of 125–130°F for medium (it will carryover cook).
Don’t overcrowd; work in batches if needed.
Make the teriyaki glaze: While salmon cooks, combine soy sauce, mirin, honey, brown sugar, sesame oil, garlic, and ginger in a small saucepan. Bring to a gentle simmer over medium heat, then whisk in the cornstarch slurry. Simmer 30–60 seconds until glossy and slightly thick.
Remove from heat.
Glaze the salmon: Brush the salmon generously with the teriyaki glaze as soon as it comes out of the air fryer. The heat helps it set and shine.
Assemble the bowls: Add a scoop of rice to each bowl. Top with glazed salmon, cucumbers, carrots, avocado, and green onions.
Sprinkle with sesame seeds. Add a squeeze of lime and a drizzle of sriracha or spicy mayo if you like heat.
Serve immediately: Salmon is at its best right away—tender and saucy with a little crisp at the edges.
