It's really simple. Use MyCrypto instead of Myetherwallet. It's made by the same team, It looks the same and it has more improvements so there is no reason why you wouldn't use it.
I haven't seen a single phishing attempt yet targeting Mycrypto, most likely because hackers are not really aware of it as of now as not many people use it. Either way, the domain name is shorter so It's unlikely that you'll fall it.
That we have not started seeing the phishing sites of My Crypto does not mean hackers are not aware of it. We still need to be very careful before clicking on any site. You never can tell how hackers will come in and it might be a time we least expect.
If you already know the original sites of most of them, you can just bookmark.
