Tips

• Skip the food court almost entirely. The pizza, hot dog/Polish bun, churro, twist soft-serve, and fountain soda are all high-carb. If you must order, the closest thing to keto is a hot dog or Polish sausage eaten without the bun, but you'll usually do far better grabbing food off the grocery floor.
• Make the rotisserie chicken your anchor buy. It's one of the cheapest cooked proteins anywhere, it's keto as-is, and one bird feeds you for days. Pull the skin on (extra fat is fine on keto) and just be aware the sugar in the seasoning brine is negligible per serving.
• Load up the cold case: blocks and shredded cheese, string cheese, deli meats (salami, prosciutto, roast beef, turkey), eggs, and pre-cooked bacon or sausage. These are your grab-and-go keto staples and they store well in bulk.
• Watch the nut aisle for hidden sugar. Plain almonds, pecans, macadamias, and walnuts are great keto snacks, but skip honey-roasted, yogurt-covered, and trail mixes with dried fruit or chocolate candies, which spike the carb count fast.
• Read the rotisserie-adjacent and deli traps. Chicken bakes, the chicken Caesar 'salad' kits with croutons and dressing, mac and cheese, street tacos, and the giant muffins/croissants from the bakery are all carb bombs hiding in plain sight near the proteins.
• For drinks and 'healthy' snacks, check labels hard. Kirkland sparkling water and plain coffee are fine, but the food court smoothie, juice, kombucha, protein bars, and many 'keto' branded snacks at Costco carry added sugars or maltitol that can stall you, so verify net carbs before bulk-buying.

Frequently asked questions

Is anything at the Costco food court keto-friendly?

Barely. The food court is built around carbs: pizza, the bun on the hot dog and Polish dog, churros, soda, and the smoothie are all out. Your only realistic move is ordering a hot dog or Polish sausage and not eating the bun, but even that comes with sugar in the dog itself. Most keto shoppers skip the food court completely and eat from the grocery floor instead.

Is the Costco rotisserie chicken keto?

Yes. A whole rotisserie chicken is essentially protein and fat with only a trace of carbs from the seasoning brine, so it fits keto easily and is one of the best-value keto proteins you can buy. Eat the skin for extra fat. Just avoid the prepared chicken bakes, Caesar salad kits with croutons, and breaded chicken products sold nearby, which are not keto.

What should I buy at Costco for a week of keto meals?

Build around whole proteins and fats: a rotisserie chicken, eggs, deli meats and salami, cheese (blocks, shredded, and string), pre-cooked bacon or sausage, ground beef or salmon, avocados, olives, and plain nuts like almonds, pecans, and macadamias. Add leafy greens and low-carb veggies. Skip the bakery, bread, rice, pasta, granola, dried fruit, and most snack multi-packs.

Are Costco's nuts and trail mixes okay on keto?

Plain nuts are great keto snacks. Almonds, pecans, walnuts, and especially macadamias are low in net carbs and high in fat. The problem is the flavored and mixed versions: honey-roasted nuts, yogurt-covered nuts, and trail mixes with dried cranberries, raisins, or chocolate candies add a lot of sugar. Check the net carbs on the label and stick to plain, raw, or dry-roasted bags.
