Costco is known for its bulk-sized bargains and high-quality private-label goods, but it’s also an underappreciated goldmine for efficient and affordable meal prepping. Whether you’re looking to save time, reduce food waste, or cut down on weekly grocery runs, prepping a week of meals using just Costco products is entirely doable—and surprisingly cost-effective.

This guide shows how families can build balanced, delicious meals for four people while sticking to Costco’s signature large-quantity offerings.

Why Costco Works for Meal Prep
