Costco is one of the most successful membership stores in the country. Members pay the annuity to get great prices in larger packs, and to stock up on products that, in many cases, are not found in any other supermarket.
While each store has different things, depending on logistics and availability, there is more or less an average of products nationwide, at least in the United States. Even so, each person has their own shopping list, and we have talked to some loyal Costco shoppers, and they told us what are their favorite products are that they always have in their cupboards, to prepare a delicious dinner.
The most purchased items from Costco
One of the clients we talked to was Abigail, who told us that, every time she visits a Costco, she buys the skinless, boneless salmon fillets.
Fresh farmed Atlantic salmon is $9.99 per pound at Costco and comes ready to lay straight in the pan or oven. Be careful of the fillets not going dry or overcooked because, since it does not have skin, it is easier to ruin it.

A housewife and mother, who identified herself as Lisa in the questionnaire, said that she really likes to buy the Kirkland Signature chicken thighs, exclusive to Costco. They are usually cheaper than the breast and are juicier and flavorful. The packages have more than 6 pounds (2.72 kg) of chicken and cost $11.99 at virtually any Costco in the United States.
Kirkland Signature taco kits can be an easy and quick option to solve dinner at times when you don’t have as much time to cook, as Jonathan, who lives with his daughter Sam, told us. The chicken already comes seasoned and cooked, and brings all the basics for a good taco: Meat, cabbage with carrots, cheese and more. Of course, bring a mountain of ready-to-assemble tortillas and sauces to throw on top.
At just $10.69, you will get two packs of 680gr.

Mamma Mia!, Maria says every time she buys the Kirkland Signature’s Five Cheese Tortellini. They come stuffed with delicious Parmigiano reggiano cheese. You have to boil them for a few minutes in water with a pinch of salt, and then you can dip them into your favorite sauce. Maria said that she usually uses tomato sauce and a handful of grated Parmesan cheese to crown this wonderful italian dish.
Bailey could get together with Maria and prepare her tortellini, because her favorite product, which she always has at home for versatility, quality and taste, is the Victoria White Linen Marinara Sauce. She often gets two 40-ounce jars for just about $9. Such a deal, Bailey, thanks for the tip!

Kelly said she likes to always have a bag of Kirkland Signature’s sirloin beef patties in her freezer, which can be cooked straight from frozen. For 18 of these 1/3 pound burgers, this nurse and mother of two pays $26.99.
Several people recommended Kirkland Signature olive oil, one of the best value for money. A 2-liter bottle of extra virgin olive oil, certified organic by the USDA, sells at Costco for $11.99. This is like, the holly trinity of the Italian food, but you can use it even in cakes or pastries. Google it, I’m not lying.

Naomi learned to eat noodles in all its forms from her grandparents and her parents, Japanese Americans, who have a restaurant in San Francisco. But she told us that she is vegan, so she has to adapt the recipes to be free from animal products. Luckily for her, she found the Miracle Noodle Plant Based Noodles made from konjac flour, without wheat flour: For that, beside being vegan this noodles are gluten-free. You won’t believe it, but it only has 5 calories per serving, and they are suitable for Keto and Paleo diets.
To complete the Mediterranean diet, you can not forget to throw in the shopping cart a few cans of Cento San Marzano tomato, 100% harvested in that Italian town, famous for its unique tomatoes consumed all around the world. A pack of 3 cans is worth, $8.99, practically a steal!
Pre-washed and pre-cut vegetables are perfect for preparing meals easily and quickly. Brussels sprouts are Andrea’s favorite because they last so long in the fridge. Her kids love them and they are so nutritious. It takes few oven or air fryer minutes to be ready and, if you don’t get to eat them all, you can freeze them and use them gradually.
Of course, one of Costco’s greatest hits is their $4.99 rotisserie chicken, which is impossible to compete with. You can break it into four to accompany it with a mashed potatoes, or use it as a base to prepare other more creative dishes.
But how does Costco manage to keep that price on its chicken, when in other supermarkets it is worth almost twice as much? We’ve done the research and told you all the secrets here.
