I always have a jar of Kirkland Signature Italian Basil Pesto in my fridge—it’s one of those Costco staples that I reach for constantly. Whether I’m tossing it with Kirkland’s Five Cheese Tortelloni (which I’ll be interlinking to later!) or using it as a spread, this pesto delivers fresh, bold basil flavor that instantly elevates any dish.
If you’re wondering whether this massive 22 oz jar is worth buying, here’s why I think it’s one of the best Costco condiments you can have in your kitchen.
Product Overview
- Flavor Profile: Classic Italian pesto with basil, Parmesan, and pine nuts
- Texture: Smooth, slightly chunky, rich with olive oil
- Cost at Costco: Typically $8–$10 for a 22 oz jar
- Refrigerated? Yes, found in the chilled section
- Serving Size: 2 tablespoon per serving (plenty of flavor in just a little bit!)
It’s a massive jar, but since I use it so often, I never have trouble finishing it before the expiration date. It lasts for weeks in the fridge after opening, and you can also freeze small portions if needed.
Taste & Texture – Why I Love It
Rich, Bold Basil Flavor
This pesto has a super fresh basil taste, balanced with nutty Parmesan, a hint of garlic, and just enough pine nuts for texture. It’s smooth but not overly pureed, with tiny bits of basil and cheese that make it feel homemade.
How It Compares to Fresh Pesto
I’ve made fresh pesto before, and while homemade is great, this Costco version is just as good but way more convenient. It has a deep, authentic Italian flavor, without being too salty or overpowering.
Perfect for Pasta – Especially Tortelloni!
My absolute favorite way to use this pesto is tossed with Kirkland’s Five Cheese Tortelloni (which I’ll be linking to!). The garlicky basil goodness melts into the warm cheese filling, creating an easy, restaurant-quality meal in just minutes.
My kids love this combo, and honestly, so do I—it’s comfort food with a gourmet twist.
Ways I Use This Pesto (Besides Pasta!)
Even though pasta is my #1 way to enjoy it, this pesto is super versatile. Here are a few of my go-to uses:
✅ As a Spread – On sandwiches, wraps, or even avocado toast
✅ Pizza Base – Instead of tomato sauce, pesto makes a fresh, herby pizza
✅ Dipping Sauce – Mixed with a little olive oil for a quick bread dip
✅ Marinade for Chicken or Fish – Adds instant flavor to proteins
✅ Drizzled Over Roasted Veggies – Makes roasted potatoes or zucchini extra delicious
If I have leftover pesto, I sometimes freeze it in an ice cube tray for quick portions later!
Nutrition & Ingredients – High Quality & Real Ingredients
One of the reasons I prefer this pesto over other store-bought brands is the high-quality ingredients.
- Made with 100% Italian Basil
- Contains REAL Parmesan & Romano Cheese (not the fake powdery kind!)
- No Artificial Flavors or Preservatives
- Uses Extra Virgin Olive Oil (not vegetable oil like cheaper brands)
It’s definitely on the richer side, with about 170 calories per 2 tablespoon serving, but since it’s so flavorful, you don’t need a ton to make a dish shine.

Final Verdict – My Favorite Costco Condiment!
