When my husband first suggested that we get aCostco membership, I scoffed. There are only two of us at home, so I doubted that we would find savings on bulk items—and be able to use them up before their expiration dates. Within our first few shopping trips, though, I realized I had been proven wrong.

Like other Costco shoppers, I almost instantly became a fan of the warehouse’s private-label Kirkland Signature products. Beyond just having a great price point, I found that these products delivered on the quality Costco promises—and I liked them better than the original products they’re emulating. Below, I’ve rounded up several Kirkland Signature products that have become staples in my kitchen.

I Shop at Costco Every Week Even Though We’re a Family of 3—Here’s What I Buy

1. Organic Non-Dairy Oat Beverage

Dupe for:Oatly Barista Blend

While I’m not lactose-intolerant, I prefer to use oat milk in my morning coffee. I was an Oatly Barista Blend devotee for the longest time, but when the pandemic hit, it became impossible to get at the grocery store, so I gave Costco’s Kirkland Signature brand oat milk a try. I haven’t missed the Oatly one bit: I love that Costco’s version is shelf-stable, and at $11.99 for six boxes, it’s about half the price. It’s also smooth and creamy, and it never breaks in my coffee like some oat milks can.

2. House Blend Whole Bean Coffee, Medium Roast

Dupe for:Starbucks Pike Place Medium Roast Whole Bean Coffee

3. Extra Virgin Italian Olive Oil

Dupe for:Filippo Berio Extra Virgin Olive Oil

Olive oilis my go-to cooking oil, as well as the backbone of homemade salad dressings and sauces, so I often look for the best value I can find. To me, that’s Costco’s Extra Virgin Italian Olive Oil—it’s a bargain, at $25 for 2 liters, but also a quality product. It’s a certified Italian product with a traceable chain of Italian origin, meaning that the olives are grown, pressed and bottled in Italy in accordance with the country’s authenticity standards. For olive oils that are even more authentic, keep an eye out for Kirkland Signature Toscano olive oil bottles labeled with PGI, or protected geological indication, as these will be sourced in Tuscany and indicate the harvest on the label.

4. Italian Parmigiano Reggiano

Dupe for:BelGioioso Parmesan Cheese

5. Egg Bites

Dupe for:Starbucks Egg Bites

These protein-packed sous-vide egg bites are perfect for breakfast on-the-go and are a dead ringer for the ones you’ll find at your local Starbucks. (They’re even available in the same two flavors: egg white with roasted red pepper and bacon with Gruyère.) While these egg bites come refrigerated, I like to keep a box in the freezer, so after microwaving the bites for just a minute or two, I’ve got a healthy (and filling) breakfast ready. Plus, this isn’t the only Starbucks breakfast dupe you’ll find at Costco: mine also just began carrying spinach, feta and egg white wraps, which seem super similar to the wraps available at Starbucks.

6. Lightly Breaded Chicken Breast Chunks

Dupe for:Just Bare Lightly Breaded Chicken Breast Bites

I may be a grown adult with no children, but my freezer is never without chicken nuggets. They can easily betossed on top of a salador into a wrap, or they can be eaten with a dipping sauce and some raw veggies. But being a grown-up, I tend to opt for the “healthiest” version I can find—meaning zero additives, ingredients I can understand, and a light breading. Costco’s house-brand version hits on all those points and comes in cheaper than the Just Bare nuggets that are also stocked at the warehouse.

7. Cauliflower Crust Supreme Pizza

Dupe for:Milton’s Cauliflower Crust Roasted Vegetable Pizza

When I need a weeknight dinner in a hurry and don’t want to splurge on takeout, I reach for these gluten-free pizzas. The cauliflower crust cuts back on carbs and gives me an extra serving of veggies, and it holds a slew of additional roasted vegetables and three different cheeses. Plus, Costco fans rave that these are comparable to other name-brand gluten-free pizzas but are about $2 cheaper than other available options at the warehouse.

What’s Healthier: Cauliflower Pizza Crust or Whole-Wheat Pizza Crust?

8. Kettle Brand Krinkle Cut Pink Salt Potato Chips

Dupe for:Kettle Brand Potato Chips

9. Salted Grass-Fed Butter

Dupe for:Kerrygold Salted Butter
