Probably my biggest couch coop recommendation (especially since you like Overcooked) is Plate Up. Up to four players cooperate to run a restaurant. Each day you earn money, which you can spend on randomly generated things like additional tables, sharp chef's knives, a mop, an oven, and so on. Every few days you will have to pick a complication, like adding another dish to the menu, or breaking the parties down into parties of one (so it's the same amount of guests using many more tables). The goal is to make it through fifteen days of service without a single dissatisfied guest, so it's like a restaurant roguelike. It's fantastic, and I recommend it highly.
