11 Costco Foods That Save You Money Long-Term

Buying in bulk doesn’t always mean saving money—but at Costco, certain foods consistently pay off over time. These picks have long shelf lives, freeze well, or replace pricier store-bought alternatives, making them smart staples for your pantry and freezer. If you want to stretch your grocery budget without sacrificing quality, start here.

Kirkland Signature Olive Oil

High-quality olive oil is expensive almost everywhere else. Costco’s version offers premium taste at a fraction of the cost, and the large bottle lasts months for everyday cooking.

Rotisserie Chicken

Costco’s famously affordable rotisserie chicken can become multiple meals—think soups, casseroles, salads, and sandwiches—making it one of the best dollar-per-meal deals around.

Frozen Chicken Breasts

Buying frozen chicken in bulk locks in a lower price and prevents waste. You can pull out only what you need, saving money compared to smaller, fresh packs.

Rice (White or Brown)

Rice has an incredibly long shelf life and costs significantly less per pound at Costco. It’s a budget hero that works in countless meals.

Kirkland Signature Butter

Butter freezes beautifully, and Costco’s multi-packs are far cheaper than buying sticks weekly at the grocery store—especially during baking season.

Frozen Vegetables

Costco’s frozen veggies are flash-frozen at peak freshness and last for months. They reduce food waste and eliminate the need for frequent produce runs.

Oatmeal

Buying oats in bulk saves serious money over time. They’re shelf-stable, versatile, and perfect for breakfasts, baking, or even savory dishes.

Cheese Blocks

Large blocks of cheese cost less per ounce and last longer than pre-shredded versions. You can shred, slice, or freeze portions as needed.

Eggs

When prices spike elsewhere, Costco often stays competitive. Eggs are a flexible protein that can stretch meals and replace costlier ingredients.

Kirkland Signature Nuts

Nuts are expensive in small packages, but Costco’s bulk pricing makes them affordable long-term—especially since they freeze well and last months.

Coffee Beans

Buying coffee at Costco can save hundreds over the year. Whole beans stay fresh longer, and the price per pound beats most grocery stores and coffee shops.
