It's been a while since I've cooked it

[Maybo]

I've seen people use 'since I cooked' or "since I've cooked". What's the difference?

I: I made curry chicken last night. It's been a while since I've cooked it. (I can't recall how long ago I have cooked it)
My Friend: I just had curry chicken this morning.

You are talking about the curry chicken that you cooked, probably early in the day.

It's been a while since I've cooked it.
You are talking about how long you last cooked curry chicken.

I don't understand. Do you mean after finishing cooking, I didn't eat it and put it somewhere for a while?

It's been a while since I've cooked it.
You are talking about how long you last cooked curry chicken.

What's the difference?
1. It's been a while since I've cooked it.
2. It's been a while since I last cooked it.

2. It's been a while since I last cooked it.

At least in AmE, both 1 and 2 are commonly used to mean that it's been a long period of time since you last prepared that particular dish. 'Long' is of course subjective, but you're referring to weeks, months, or even years.

However, 1 could also mean it's just been an extended period from earlier in the day.

What anybody means by any particular statement is pretty much a guess outside of context. Maybe they are talking about that dish for some reason. The person says, "I'm not sure I know how to make that. It's been a while since I've cooked it " Now it means something.
