Greek yogurt has become a popular go-to for those seeking a protein-packed, calcium-rich alternative to traditional yogurt. Consumers love its health benefits and tangy taste, but there’s one drawback: it can be expensive.

Enter Kirkland Signature Greek Yogurt.

Costco Greek Yogurt offers an affordable solution. Priced significantly lower than other brands, it’s a regular find in the warehouse. But is it any good? We bought a tub to determine whether it deserves a spot in your cart.

Kirkland Signature Greek Yogurt offers a budget-friendly alternative to pricier brands without sacrificing quality. Priced at just $5.99 for a 48-ounce container, it provides a 30% savings compared to similar options. With organic ingredients and a fat-free profile, it meets most nutritional standards for Greek yogurt. While its texture is slightly thinner and its flavor milder than other brands, it’s a versatile choice perfect for recipes or as a healthy breakfast base.

Located in the refrigerated section near bacon and other yogurts, Kirkland’s Greek Yogurt is sold in 48-ounce containers for just $5.99—only 12 cents per ounce! In comparison, similar brands at grocery stores are around 18 cents per ounce, meaning you’re saving 30% by choosing Costco.

Organic and Fat-Free: What Does It Mean for You?

A glance at the packaging reveals that Kirkland’s Greek Yogurt is organic and fat-free. According to the USDA, organic dairy products have nutritional profiles similar to those of conventional versions. A big difference is that organic ensures cows are raised without growth hormones or antibiotics.

The fat-free label is great if you’re watching calories. However, fat contributes to satiety, so you might not feel as full after eating this version as you would a full-fat option.

Nutritional Breakdown: Does It Stack Up?

Costco’s Greek Yogurt holds up well against typical Greek yogurt nutritional standards. Ideally, a plain Greek yogurt should contain just milk and active cultures, no added sugars, 16-20 grams of protein per serving, 160-240 milligrams of calcium, 120-130 calories, 2-6 grams of naturally occurring sugars (from lactose), and 2-2.5 grams of saturated fat.

The Kirkland version checks nearly all these boxes—with the added bonus of being fat-free.

The Big Question: How Does It Taste?

So, we know it’s a great price and meets the health requirements, but how does it taste? At first, you’ll notice that it’s slightly thinner than full-fat Greek yogurt, though it’s not runny. This lighter consistency works well in recipes like dressings or sauces, but if you’re used to eating yogurt alone, you may miss the creaminess.

As for flavor, Costco Greek Yogurt has a milder tang compared to brands like Fage. You’ll notice the difference if you’re accustomed to that sharp, tangy taste. But for those new to plain Greek yogurt, this version’s more subtle flavor makes it a great introduction—and perfect for letting your toppings take center stage!

How We Enjoy Kirkland Greek Yogurt

We love using this yogurt in a variety of ways! It pairs perfectly with honey and berries for a quick, healthy breakfast. It’s also a fantastic base for salad dressings or a 1:1 swap for mayo or sour cream in your favorite recipes.

In short, Kirkland Signature Greek Yogurt delivers on price, nutrition, and versatility. Give it a try the next time you’re in Costco—it might become a new staple in your fridge!
