Every fall I make Ina Garten's coq au vin. Even though cooking six nights a week takes a lot of meal ideas, I only make this in the fall (I'm an extremely seasonal cook) (except when I get a craving for chicken tortilla soup in July). Nick looks forward to it every year, and I think that's partly because he knows beef bourguignon isn't too far behind, as a winter dish.
I like cooking on Sundays because I'm never rushed. Chances are I haven't had a terrible day and I'm not exhausted from work and the chicken isn't still frozen, despite spending time overnight in the fridge. I can take my time, start cooking at 3 if I want, have a glass of wine while measuring ingredients. I can turn on music and catch up on Instagram after I put it in the oven. It's very low-key but Sundays are some of our best meals.
I didn't get a picture of the finished coq au vin, because I know some people are weird about meat, which is fine with me. We had it with homemade garlic bread and we shared a Napoleon after dinner. I had a glass of wine which hit me like a ton of bricks (my college self is so embarrassed) and I washed dishes while Nick ate more bread. I like Sundays.
