Shopping at Costco doesn’t have to mean buying mega jars of mayonnaise. Here’s how to shop for a small household at the warehouse.

Costco isn’t just for shopping—it’s a way of life. My family makes regular trips to our warehouse for household staples, fresh ingredients and pantry basics, and, let’s be honest, a few extras that are too good to pass up (Costco sushi, cheesecake are just a couple of the non-essentials that have found their way into our cart). And the food court alone is worth a trip. But we’re not feeding a family of six or even four. It’s just the two of us: my husband and I, plus one bottled-chaos pup.

Friends always tell me that they don’t shop at Costco because they don’t have extra space or use for mega packs of cereal or giant bottles of ketchup. I’m here to dispel that myth. First, you don’t have to buy huge bottles of ketchup; save one-off condiments for your regular grocery store trips. You absolutely will buy larger quantities of items at Costco, but the items you pick should make sense for your household.

For instance, we cook a lot at home and are big fans of keeping the freezer and pantry stocked for menu and meal planning (it’s my biggest tip for getting dinner on the table fast). Paper products and laundry detergent are go-tos, things we can tuck away in a closet so we don’t run out. Costco is essential for holiday baking supplies like organic flour and sugar, and I swear Costco was the only place that still had eggs when there was a shortage everywhere else.

A Costco membership is absolutely worth it for a small household if you know how to shop there. Here are some tips for getting the most out of your next trip.

Plan Your Meals and Go with a List

I’m a big list-maker, and a list is particularly helpful when grocery shopping to keep me or my husband on track. Our running digital grocery list for Costco has go-to items and things we always keep stocked at the house. But the list also helps us think and plan for future meals. For instance, if we’re entertaining guests, I might pick up extra organic greens for salad recipes, blocks of cheese for a cheese board, and meats to throw on the grill.

Visit Once or Twice a Month

The beauty of Costco is that you don’t have to go every other day or even once a week. Buying larger quantities of items you can easily store for future use means going once or twice a month. We go grocery shopping at Costco about once every five to six weeks at my house to stock up on our usual suspects.

It’s not sexy, but shopping at Costco is essential for toilet paper, laundry detergent, toothpaste, pain relievers, dishwashing liquid, trash can liners and more. We have just enough storage space for the extras, so we never run out.

Buy Things with a Longer Shelf Life

Our pantry always contains dried pasta, olive oil and other cooking oils, crackers, coffee, canned San Marzano tomatoes, walnuts, oat milk and coconut water—all of which we buy at Costco. You can get many non-perishable items at the warehouse—including beer, wine and spirits, depending on your state.

Shop the Frozen Section

We always have three things in our freezer: organic frozen fruit for smoothies, organic broccoli for roasting or stir-fry recipes, and frozen, uncooked, shell-on shrimp for any shrimp recipe under the sun.

But Don’t Skip the Fresh Produce

If your household eats a lot of fresh fruits and vegetables, Costco is a savior (especially during the winter months). We regularly stock up on fresh berries, greens or lettuces, mushrooms, carrots, sweet potatoes and baby potatoes—most of it is organic, too. I put Organic Girl power greens or organic spinach in just about everything, from pasta recipes to smoothies, so we’ll always grab a box or bag.

Premade Items Can Be a Lifesaver

I’ll never forget the first time I witnessed the Costco rotisserie chicken frenzy when they restocked the chickens. I avoided the scrum! But we’ll occasionally buy a whole rotisserie chicken to divide up for several meals, from chicken salad to chicken enchiladas. Break it down and freeze the meat for later use, including the bones, which you can use to make chicken broth.

Freeze Everything You Can

We don’t have a separate freezer (although sometimes I wish we did), yet we find room for freezing extra food in our run-of-the-mill kitchen freezer. We freeze meat, breads (the Costco ciabatta rolls are great for everything from burgers to sandwiches and croutons) and occasionally baked goods (muffins!). I love Tortilla Fresca Uncooked Flour Tortillas, which are found in the refrigerated section. They’re raw and come in packs of two; we always freeze one.

We’ll buy a pack of four New York strips, eat two and freeze the other two for another meal. Organic chicken breasts and ground beef are sold in smaller packs that are easily stored in the freezer. We’ll freeze fresh crab meat if we’re not going to eat it right away, and sometimes fish (depends on what it is and whether it was already frozen). And don’t forget that you can freeze butter!
