Trying to narrow down the best keto Costco options is honestly kind of difficult, because there are a lot of them.

For anyone attempting the keto diet, meal planning and prepping is key. And, for those who like buying and prepping in bulk, Costco is the spot. Not only does the members-only warehouse have a plethora of keto-friendly choices, they also have some exclusive products that can make the keto experience a lot more tasty.

“We do have a variety of great products to choose from, including organic products,” said Muriel Cooper, a member of the communications team at Costco.

We did our research to figure out the best keto-friendly options that the superstore stocks, besides the basic keto staples. Let’s just say we don’t think you’ll be disappointed in the amount of snack, condiment, and cheese platter options that can be yours with one swipe of your Costco card. (Pro-tip: If you don’t have a membership, you can still shop for many non-perishable Costco items through Google Express or Instacart!)

Ready-To-Eat Meals

Costco pulled pork


While you should be careful of the salt content in ready-to-eat meals, there are so many benefits to keeping a few on hand when you’re knee-deep in keto. For one, they make for easy weeknight options. For another, they can be a savior when you don’t have leftovers (or extra money) for lunch.

Costco stocks several keto-approved ready-to-eat meals in the refrigerated/frozen section, including:

  • Del Real Foods Seasoned Beef And Barbacoa Sauce
  • Del Real Foods Pork in Chile Verde Sauce
  • Del Real Foods Shredded Beef
  • Don Lee Grilled Chicken Patties
  • Kirkland Signature ABF Pulled Pork
  • Kirkland Signature Fully Cooked Angus Beef Patties
  • Kirkland Signature Rotisserie Chicken (said by many to be the best rotisserie chicken on the market, and it has a Facebook fan page)

Pair any of these with cauliflower rice for a quick meal that’s easy to dress up with difference sauces, veggies, and garnishes.
