Oysters are in season now, so I made oyster dishes for dinner today.
One of them is "Takikomi-gohan" that is a Japanese common rice dish cooked with other ingredients.
I think it is a bit like paella.
My husband was favorite it very mush so that he ate a lot.
===========================
牡蠣の季節なので，今夜は牡蠣料理を作りました．
そのうちの一つが"炊き込みご飯"です．これは日本の一般的な米料理で，ご飯と他の具材を一緒に炊いて作ります．
パエリアに少し似ていると思います．
夫はとても気に入ったようで，たくさん食べていました． soa natural?

Only one mistake that I can see. It's still easy to understand, but a little unnatural.

"My husband was favorite it very mush so that he ate a lot."

Your husband ate more because of how much he enjoyed your cooking. This is easy to understand. But the phrasing is a little awkward.

"My husband really liked the dish! So much that he ate seconds." Something like this would sound more natural. The problem is "Was favourite it very much." the tense is wrong and makes the sentence sound awkward.

you can write it as "My husband favored it a lot." but it sounds unnatural.
