Grease the Air Fryer Basket with cooking spray and then slide inside.
Adjust the temperature of Air Fryer to 390 °F to preheat for 5 minutes.
In a large-sized bowl, add broccoli florets, garlic, peanut oil and salt and toss to coat well.
After preheating, arrange the broccoli florets into the greased Air Fryer Basket in a single layer.
Slide the basket into Air Fryer and set the time for 5 minutes.
While cooking, toss the broccoli florets once halfway through.
Meanwhile, in a small, microwave-safe bowl, place the maple syrup, soy sauce, Sriracha and vinegar and blend well.
Microwave on high for about 10-15 seconds until the maple syrup is melted.
Remove from the microwave and stir until smooth.
After cooking time is finished, remove the broccoli florets from Air Fryer and transfer into a large-sized bowl.
Add the maple syrup mixture and toss to coat well.
Serve immediately.
