Cuz I sure as hell didn't. I happened to see an announcement from them in anticipation for season 2 of the series (which starts tomorrow!!) and I wanted to share! The official website of the drama series gives recipes for many of the recipes from season 1 of the show (most of which are the same dishes or very similar to the original manga). They're all in Japanese, but you can get pretty reasonable instructions with a translate tool. Here they are!
Nomoto-san's Giant Lu Rou Fan (braised pork over rice) from episode 1
Nomoto-san's Giant Omurice from episode 2
Nomoto-san & Kasuga-san's Grilled Riceballs with Sendai Miso from episode 2
Nomoto-san's Whole Pumpkin Pudding from episode 4
Nomoto-san's Kinchaku Eggs (eggs in fried tofu pouches) from episode 5
Nomoto-san's Harako Meshi (salmon rice topped with salmon roe) from episode 6
Nomoto-san's Stollen-style Pound Cake from episode 7
Nomoto-san's Roast Beef from episode 9
I'm really happy I found out about these, definitely gonna recreate some of these!! I already made the miso riceballs once when I was rewatching the show with my roommate, and we just used some recipe we found online. Now we have the legit version :D Definitely wanna make the pumpkin pudding someday. I'm super happy this exists even though it doesn't have all the recipes from the show, like for the udon that Kasuga makes for Nomoto, or their homemade gyoza. I hope they'll continue releasing recipes for the dishes of season 2 as it airs as well!
