How to Make It
Coat broccoli florets well with cooking spray. Place half of the broccoli in air fryer basket, and cook at 375°F until tender-crisp, 6 to 8 minutes. Repeat with remaining broccoli.
Meanwhile, place evaporated milk, queso fresco, ají amarillo paste, and saltines in a blender; process until smooth, about 45 seconds. Pour sauce into a microwaveable bowl. Microwave on HIGH until warm, about 30 seconds. Serve cheese sauce with broccoli.
