I think you need to separate two things:
Is it ideal/great parenting?
Is your husband wrong to point it out?
They aren't entirely related. Because your husband could be (about half of the replies seem to agree with him) right, that it is a bit lazy. Personally, I didn't do it when my son was 10 months old, and I don't buy the stuff about "independent play" - we all know that isn't the reason, it is just a justification that some on here give after the fact.
Personally, in your shoes, you say that your child can entertain themselves for 30-60 minutes while you watch TV, but then needs to see something themselves while you cook? So why not just do the food prep/as much of the cooking while they are happy entertaining themselves? I know they are in different rooms, but worst case - bring some of the chopping into the living room? do you have a table in there? Or can you move the playpen so it can be seen through the kitchen door? This is obviously very house-dependent...
Anyway, none of this answers the second question though, which is - is your husband wrong to point it out? Because for that, it depends on how your husband is. Is he a devoted dad who gives 100% all the time, when he isn't working to his daughter? Never shows her screens, never ignores her for what he wants etc? If so, then maybe he is justified in criticizing you.
But if he isn't the perfect dad? Then obviously calling you lazy was very wrong.
