Q:

Single word for neutral tasting?

My friend is a food blogger, we often go to new restaurants and try new food,but English is not our first language so I need help.
What can be a single word for food that is neutral tasting. Like if a dish is good in taste but with a little more seasoning it could have been better. So it's not really bad.
I would use the word bland but it seems a bit negative.
Thanks in advance.

A:

Personally I think bland is probably the right word for what you're describing, but if you think it's too negative, you could use mild. It's specifically used when describing food where the flavor is not as strong as it could be, but it's not negative, because some people prefer less seasoning. 
Often but not always referring to heat, it can also mean a lack of strong seasoning or flavor. Mild implies the food is deliberately not strong-tasting as a matter of preference, rather than a lack of effort. "The last curry I made was too spicy for you, so I made it mild this time. I think you'll like it." 

A:

plain
Cambridge dictionary

not decorated in any way; with nothing added: The food is pretty plain (= prepared simply and without strong flavors), but there’s lots of it.

flat
Merriam-Webster

a. : lacking flavor

e.g. This dish tastes a little flat

insipid
Oxford dictionaries

Lacking flavor: mugs of insipid coffee

vapid
American Heritage dictionary

Lacking taste, zest, or flavor; flat: vapid beer.

savorless/savourless
thefreedictionary

lacking taste or flavor or tang

flavorless/flavourless
Cambridge dictionary

having little or no flavour : These grapes are completely flavourless.

I would say "plain/flat" is most neutral, "vapid/insipid" less so, and "savorless/flavorless" least so.

some other options: zestless, lacking tang, dry, dull, unsavory, plastic, garden-variety, so-so, humdrum, cut-and-dried

You seem to be saying that there's not enough seasoning.
Well then it's underseasoned. Just say what you want to say :)
Example usage:

And in any case under- is a productive morpheme, meaning you can generate words with it, basically, at will.

under-
Prefix

Insufficiently; incompletely:
"Undernourished"

Obviously you can then modify this to soften it or be harsher to your heart's content: "a little underseasoned", "very underseasoned", "disappointingly underseasoned", "career-endingly underseasoned" etc. etc.
