You don't have to pick up the name brands from the shelves at Costco to get the best deals. In fact, one of the great things about Costco is its Kirkland Signature brand.

The in-store brand has products that are similar in quality to their name-brand versions but are less expensive. That can help you save money on groceries and keep more money in the bank.

But which Kirkland Signature options have the best quality? Here are a few of Costco's products you should try the next time you do a Costco run.

Rotisserie chicken

A rotisserie chicken is a great addition to your Costco shopping cart when you head to the warehouse retailer.

You can pick up a chicken for an easy dinner by simply carving it up to feed the family. You can also just pull the meat off the bone and add it to a chicken salad recipe or mix it with some barbecue sauce for a shredded chicken sandwich.

Applesauce

Applesauce can be messy on the go, but Kirkland Signature's applesauce pouches are sure to keep your kids happy or help give you some extra energy in the afternoon.

The Kirkland Signature versions are similar to name-brand options but are likely to cost you a little less. Get a pack of 24 pouches to stock up your pantry, purse, or bag when you have kids in tow.

Maple syrup

Forget that corn syrup glop on the shelves of your local grocery store and grab the Kirkland Signature maple syrup from the shelves at Costco instead.

The ingredient list is short and sweet, with just pure organic maple syrup listed as the only thing inside the nearly 34-ounce bottle.

Eggs

Egg prices have been known to be high in the past, which has put a bit of a strain on grocery shoppers. But Kirkland Signature's eggs may help ease the burden.

The warehouse retailer sells its eggs in packs of 24, so you're sure to have plenty without going overboard on the price compared to other egg sellers.

Frozen berries

If you like smoothies, Costco could give you a better option than buying them regularly from your local smoothie store.

Check out your Kirkland Signature options for frozen berries, which include strawberries, blueberries, or a special three-berry blend as part of the retailer's signature label.

Chicken stock

Chicken stock is a great ingredient to have in your pantry for a variety of recipes throughout the year. You can add it to soups or stews, as well as grab some for sauces or casseroles.

The Kirkland Signature version comes in a six-pack of resealable cartons, so you'll have plenty around to try different types of new recipes.

Grocery shopping doesn't have to break the bank when you use the right strategies. Here are three quick tips for reducing food expenses:

  • Buy store brands instead of name brands whenever possible.
  • Always make sure to compare unit prices, not just sticker prices.
  • Join your store's loyalty program so you don’t miss out on member discounts.

Even though something like choosing coupons in your grocery store app can feel like an annoying task, the savings can really add up.

Coffee

Perk up your mornings with coffee from Kirkland Signature. Costco's line of coffee includes ground coffee or whole-bean coffee.
