Premieres January 4, 2024. The English name they are going with is "Delicious in Dungeon", but personally, I like the romaji for this series better. They also released a new trailer here that you can watch. In addition, they tweeted that this will air for two consecutive cours. Synopsis from AniList:
When young adventurer Laios and his company are attacked and soundly thrashed by a dragon deep in a dungeon, the party loses all its money and provisions...and a member! They're eager to go back and save her, but there is just one problem: If they set out with no food or coin to speak of, they're sure to starve on the way! But Laios comes up with a brilliant idea: "Let's eat the monsters!" Slimes, basilisks, and even dragons...none are safe from the appetites of these dungeon-crawling gourmands!
The manga is so good. It makes me want to play a D&D character that cooks monsters.
