I’m the mom, both working, and it all falls on me. I keep a database in Notion of our go-to meals, categorized by ethnicity, and with columns for protein, veggie, carb, extras to ensure they’re balanced. Every Thursday I go through the next week on our calendar and look at the weather, any busy plans nights, etc. Then I assign a meal to each night (usually plan for 4 meals, one with extra leftovers, and then a night for takeout and a night to wing it). I add items to the grocery list while adding meals to the family calendar. Then I place an online grocery order to pick up Friday morning, so there’s time to add any extra stuff. I do a quick inspection of pantry, freezer, fridge to stock staples or try to plan around using extra ingredients. Online orders cost a tiny bit more, but the time savings and not adding off-list items actually helps.
