The easiest way to cast to your TV largely depends on the devices you already own and your personal preferences. However, here are a few generally considered easy methods:

1. Using a Dedicated Streaming Device with App Casting:

• Devices: Chromecast with Google TV, Roku Streaming Stick 4K, Amazon Fire TV Stick 4K, Apple TV 4K.
• How it’s easy:
  • These devices plug directly into your TV’s HDMI port and connect to your Wi-Fi.
  • They have their own user-friendly interfaces with apps for most streaming services (including YouTube).
  • You navigate directly on the TV using a remote.
  • To watch YouTube, you simply open the YouTube app on the streaming device and find your content – no phone casting is strictly necessary.
  • These devices also support casting from your phone if you prefer.

2. Built-in Smart TV Casting (if compatible):

• Devices: Many modern smart TVs have Chromecast built-in (Android TV or Google TV) or support Apple AirPlay 2.
• How it’s easy:
  • If your smart TV has Chromecast built-in, you can often cast directly from the YouTube app on your phone (as described in the previous response) with a simple tap of the cast icon, without needing an extra device.
  • If your smart TV supports AirPlay 2, casting from an iPhone or iPad is also very straightforward using the Control Center’s “Screen Mirroring” or the AirPlay icon within apps.

Why these are often considered easier:

• No need to constantly manage your phone’s connection: With dedicated devices or built-in casting, the TV handles the app and streaming directly.
• Phone battery isn’t drained: When the TV streams directly, your phone isn’t actively sending the video data.
• Potentially more stable connection: Dedicated devices are designed for stable streaming.
• Simple, remote-based navigation: You use a standard TV remote instead of relying on your phone’s screen.

Which is “easiest” for you will depend on:

• Your existing devices: If you have an iPhone, AirPlay to an Apple TV or AirPlay 2-enabled smart TV might be the most seamless. If you use Android, a Chromecast or Android TV might be simpler.
• Your technical comfort level: Some people find navigating a TV interface with a remote easier than casting from their phone.

In conclusion, while casting from your phone directly to a smart TV is relatively easy, using a dedicated streaming device with its own interface and app ecosystem is often considered the easiest and most reliable long-term solution for watching YouTube and other content on your TV.
