I share a Costco membership with my dad and split groceries with my boyfriend. Here are 10 products I always buy at the warehouse.

I love warm, creamy artichoke dip, and these marinated hearts are perfect for the job. They're also amazing on their own, in a salad, or served with a sprinkle of salt for a low-calorie snack.

The Kirkland Signature artichoke hearts come in a set of two large jars, so they're perfect for splitting between households. 

The Kirkland Signature rotisserie chicken is one of the store's most famous items, and for good reason. It's well-seasoned and can feed one person for a week or serve as a meal for a family of four.

I like to pinch off a chunk of leg meat with skin and dip it into the juice at the bottom of the bag for a quick snack. I also make a delicious chicken salad with the meat and use the bones for broth.

If I can't finish a whole bird, I cut it up and freeze it for later.

When I want a flavorful pancake without added calories from butter and syrup, I reach for the Kodiak Power Cakes flapjack-and-waffle mix.

This mix has a whopping 14 grams of protein per serving and is made with 100% whole grains, so it's nutritious and tastes good. I also love adding vanilla extract and oat milk for an extra punch of flavor.

The mix is packaged into three easy-to-store bags, so I distribute them among the family.

The Kirkland Signature salted grass-fed butter is made with just two ingredients: cream and salt.

I find it has a creamier consistency and tastes saltier than other versions I've had, so I use less butter than I normally would when I cook. I enjoy it on fresh, crusty bread or in brown-butter chocolate-chip cookies.  

The Kirkland Signature Parmigiano-Reggiano is both delicious and versatile. I like to grate some on top of pasta or add it to a charcuterie board with fig or apricot jam and green or kalamata olives.

One of my greatest challenges is finding milk that lasts beyond a week once it's opened and tastes good — to me, some brands are a little too watery.

The best part about the Kirkland Signature organic milk is that its expiration date exceeds that of other dairy products I've tried. For example, the milk I bought at the beginning of November didn't expire until the start of January.

There's nothing like good-quality vanilla ice cream, and the Kirkland Signature brand is my favorite store-bought version.

This dessert is creamy, full of vanilla flavor, and doesn't have those weird crunchy ice crystals that some brands tend to have. I usually enjoy it with chocolate syrup, though I occasionally go rogue and drizzle balsamic vinegar on top. 

The Kirkland Signature ice cream comes in a two-pack, making it necessary but difficult to hand a carton off to a family member or friend.

I don't typically seek out organic products, so I wasn't sure what to expect when I first picked up the Annie's mac and cheese variety pack. However, this is hands down the creamiest, cheesiest boxed brand I've tried.

Each 12-pack comes with three flavors, including classic-, white-, and aged-cheddar variations. I make this mac and cheese with Kerrygold butter and Kirkland Signature milk to ensure maximum sauce creaminess. 

I used to get a bagel and schmear with salmon every Sunday morning, but with this Kirkland Signature smoked fish, I can throw a sandwich together whenever I want.

It takes just a few minutes to prepare — I squeeze lemon on the salmon and then stack capers, red onion, a boiled egg, and tomato on a bagel with cream cheese.

This salmon comes in a two-pack, so I can keep one portion in the fridge and freeze the other for later. 

These huge jars of Skippy peanut butter — weighing 3 pounds each — seem to last forever.

I pair it with a healthy scoop of grape jelly and spread it on plain white bread. I've also mastered a peanut-butter-and-jelly smoothie, and I love to swirl a spoonful of the spread with yogurt and fruit for breakfast.

One jar goes a long way, so I like to send the other container home with my boyfriend.
