My partner and I cook almost 100% of our meals at home. I shop for groceries 1x a week, and it takes about 1 hour. Meal prep / cooking and cleaning varies a bit. We generally cook 1 roast chicken a week, and a pot roast in a slow cooker. Having pre-cooked proteins helps with meal prep time. We use a rice cooker often, and will usually toss some veggies in there with the rice to simplify things. That said, overall we probably spend 30-40 min a day on food prep, and another 10 min a day cleaning. When we cooked different meals every night, it was generally closer to 90 minutes a day on food prep / cleaning. Learning to cook takes time, learning to cook well takes more time, learning to cook efficiently and how to minimize time involved takes time.
