Meng Qi Shi Shen

- Both a historical Chinese romance anime - Both have a strong female lead - Male leads fall for the female lead after getting to know each other - Male leads are talented, smart and handsome  

This two anime have same main character who are really good at cooking and even the boy main character in this two anime are extremely powerful. They even have same act like how the main girl character got kidnapped and had to live in the main boy character clan. 

Both are isekais focused on food preparation. The food takes the central stage and looks delicious. Though beyond that, they are fairly different, because Campfire Cooking is super chill with no real challenges and is slice of life with no central conflict or goal, and Cinderella Chef is plot driven with difficulties to overcome. 

Similar setting (Imperial China) and characters. You have a strong independent female lead who gets kidnapped and forced into a lowly state, but she uses her high wits and specialized expertise to survive and advance herself. By shining so brightly, she catches the attention of a powerful handsome noble who falls for her, though she doesn't exactly return the affection, at first. The handsome noble is keeping some secrets about his identity. In the case of Meng Qi Shi Shen, she is a rising chef who gets isekaied, but manages to impress people with her culinary skills. Kusuriya no Hitorigoto is not an isekai, but might as well be one given how impressive the knowledge of the MC is even compared to modern science. She is an apothecary but is somehow also the ultimate detective. The worlds are kept fairly realistic with minimal fantasy elements. But there is a certain level of power fantasy due to how immensely capable the MCs are. Kusuriya no Hitorigoto is better though. read more 

Both our female leads, who belong to the present time, are mysteriously taken back in time to ancient China. There, not only do they have to understand her mysterious teleportation, but also adapt into the bodies of girls who actually lived during that time period. And unlike the owners of those bodies, our MCs are sharp and lively, and do not hesitate to put men in their places when they try to control them. Both these girls are also paired with tsun leads, who could very well be each other's twin. 

bit of a stretch but if you really enjoy the food aspects - the food wars, the food animation, the diner's over the top descriptions and imagery of the food as they eat them- then you'll probably enjoy both. They also both have a bit of comedy and hints of romance. 

Both are cooking focused, this also has the foodgasms but less nudity, and more plot based good comedy as well 

Gourmet isekai focusing on traditional foods from China and Japan, that are unusual in the new world. No magic involved in either story. Somewhat historical settings based on China and Germany. Meng Qi starts a bit more dramatic, but both series have a "dish of the day" format. 

A woman dies and gets isekai'ed into the body of a girl in a fantasy world, and has to depend on her wits and skills from her past life to make a life for herself. In Ascendance of a Bookworm, she happens to be an aspiring librarian with a passion for books and a knack for sales, whereas in Meng Qi Shi Shen, she's an award winning young chef. In Ascendance, the setting is a medieval European style fantasy with magic, while in Shi Shen, the setting is ancient China. In either setting, life is difficult, either born into a frail body to a poor plebeian family in a society dominated by magic wielding nobles, or being kidnapped by bandits and forced into marriage. Nevertheless, they are able to advance in their world through knowledge from the modern world or through their cooking skills. Being isekai'ed isn't going to stop them from pursuing their dream of being a librarian, or a world renown chef. read more
