Keto Essentials to Buy at Costco


One of the first things that my husband and I did when we moved into our apartment was get a Costco membership. About once every six weeks or so, we take a trip and buy all of our meat for the next month or so, as well as some produce and other essentials. Even not factoring in cost, Costco has the best fish by far of any supermarket in the city, making that worth the trip alone.

Once we decided to adhere to more of a keto-style diet, I started looking more closely at what we were buying there. To my pleasant surprise, Costco has a ton of Keto essentials at the right price!

my costco shopping list – essentials

  1. Teton Waters Grass-Fed Beef Sausage

Grass feed beef Keto Essential

I only just noticed this product appear at Costco a few months ago, and we’re now hooked! We eat sausage in our omelettes several times a week, and this particular brand is delicious and low in preservatives.

2. Aidell’s chicken sausage

Chicken and apple sausage

Even with Teton Hills beef sausage, it’s still nice to eat chicken every once in a while. I use this one in my commuter-friendly breakfast egg muffins (recipe to come soon!).

3. Almond butter

Kirkland almond butter

This almond butter is made with only almonds, unlike the Whole Foods brand. It tastes exactly like how almond butter should taste — a hint of sweetness, not an excessive amount of oil, and a whole lot of nuttiness.

4. GT’S kombucha


You can get a six-pack of GT’s gingerade kombucha at Costco for only $14.99, a discount from other retailers. However, they only sell gingerade, which is kind of a bummer.

5. in-season fruit

Pack of respberries

Costco has delicious fruit, when the fruit is in-season. I love buying berries there in June and July and apples in the fall. However, be aware that although certain fruit is sold year-round, it’s not always good. Only buy when it’s in-season, even if that means you only have a few months to get your berry fix.

6. Avocados

Pack of avocados

Costco sells avocados by the bag, and they’re always perfectly underripe when we get them. Unlike other supermarkets, Costco also sells them at a reasonable price – $7.99 for a bag rather than the $2+ each that we usually pay.

7. wild fish

Wild Salmon

Costco sells a decent variety of wide fish, including salmon, tuna, perch, and flounder. We typically buy a few packages of each. The fish is always high-quality, and the variety is great to change up our weeknight and weekday meals.

8. pickled herring

Pickled Herring

I know it might seem a little gross, but pickled herring makes a great low-carb snack. Husband likes to eat this one while he’s waiting for me to cook dinner.

9. smoked salmon

Smoked Salmon

Another healthy snack, but this one also goes quite well in scrambled eggs topped with some scallions or in a spiced omelette.

10. kerrygold grass-fed butter

Grass fed irish butter

Whether you eat butter or would turn this into ghee, this is a great addition to your kitchen.

11. avocado oil

A neutral-tasting oil that cooks well at very high temperatures, this is a kitchen essential.

 12. coconut oil

Another oil that does well at high temperatures, but with coconut flavor. I like to use it in Asian-style cooking with a dash of sesame oil.

13. Frozen Fruit

Frozen berries

If you’re making a smoothie, there’s absolutely no reason to use fresh fruit — frozen tastes just as good and gives you a nice creamy texture. Also, it allows you to get the best quality of fruit even when it’s not the height of the season.
