Costco’s Kirkland Signature brand has long been a favorite among savvy shoppers, offering high-quality products at prices that often undercut their name-brand counterparts. While staples like Kirkland toilet paper, batteries, and rotisserie chicken tend to steal the spotlight, there’s a treasure trove of lesser-known items that deserve a spot in your cart. These underrated gems deliver exceptional value, taste, and utility without the fanfare of their more famous siblings. Whether you’re a seasoned Costco member or a newcomer, here are 10 Kirkland Signature products that you should be buying on your next warehouse run. Prices mentioned are approximate as of February 28, 2025, and may vary by location.
1. Kirkland Signature Organic Extra Virgin Olive Oil
Olive oil is a kitchen essential, but quality can vary widely, and premium options often come with a hefty price tag.
Enter Kirkland Signature Organic Extra Virgin Olive Oil, a standout that punches above its weight. Priced at around $23.79 for a generous 2-liter bottle, this Mediterranean-sourced oil is certified organic and offers a robust, authentic flavor perfect for cooking, dipping, or dressing salads. What makes it underrated? It’s not just the price—though that’s a steal compared to boutique brands charging double for half the volume—but the fact that it’s consistently praised for its purity and taste. Many shoppers overlook it, assuming a store brand can’t compete with artisanal labels, but this olive oil proves them wrong. Next time you’re browsing the aisles, grab a bottle and elevate your culinary game without breaking the bank.
2. Kirkland Signature Fully-Cooked Bacon
Bacon lovers, rejoice: Kirkland Signature Fully-Cooked Bacon is a game-changer that doesn’t get the attention it deserves. At approximately $18.19 for a 1-pound pack, this pre-cooked delight requires only a quick zap in the microwave to deliver crispy, smoky perfection. Unlike traditional bacon, which can leave you scrubbing grease off your stovetop, this version offers convenience without sacrificing flavor. Shoppers often bypass it for raw bacon or name-brand alternatives, but those who’ve tried it rave about its versatility—think BLTs, breakfast scrambles, or crumbled toppings for salads and soups. With around 50 strips per package, it’s a time-saver that lasts, making it ideal for busy mornings or impromptu meals. Don’t let its understated packaging fool you; this bacon deserves a starring role in your kitchen.
3. Kirkland Signature Chicken Street Tacos Kit
Taco night just got easier—and tastier—with the Kirkland Signature Chicken Street Tacos Kit. Priced at around $18 for a 12-taco kit, this pre-made meal comes complete with seasoned chicken, tortillas, salsa, cheese, and more, all ready to assemble and enjoy. While Costco’s rotisserie chicken and frozen foods often dominate the conversation, this kit flies under the radar despite its restaurant-quality flavor and convenience. It’s perfect for a quick weeknight dinner or a casual gathering, offering authentic street taco vibes without the hassle of sourcing ingredients. The chicken is tender and well-spiced, and the included fixings strike a balance of freshness and zest. If you’ve been sleeping on this gem, it’s time to wake up and add it to your Costco haul.
4. Kirkland Signature Organic Almond Non-Dairy Beverage
For those seeking a dairy alternative, Kirkland Signature Organic Almond Non-Dairy Beverage is an unsung hero. At roughly $9.99 for a pack of six 32-ounce cartons, this unsweetened almond milk is a budget-friendly option that rivals pricier brands like Almond Breeze or Silk. It’s creamy, versatile, and free of added sugars, making it a go-to for smoothies, baking, or simply pouring over cereal. What sets it apart is its clean ingredient list and subtle nutty flavor, which doesn’t overpower recipes the way some overly sweetened alternatives can. Many shoppers stick to name brands out of habit, but this Kirkland offering delivers comparable quality at a fraction of the cost. Whether you’re lactose-intolerant or just cutting back on dairy, this is a must-try.
5. Kirkland Signature Tuxedo Chocolate Mousse Cake
Dessert lovers often flock to Costco’s sheet cakes or tiramisu, but the Kirkland Signature Tuxedo Chocolate Mousse Cake deserves more love. Priced at around $23, this multi-layered masterpiece features rich chocolate cake, creamy mousse, and a glossy ganache topping that rivals bakery offerings. It’s decadent yet balanced, making it a crowd-pleaser for gatherings or a luxurious treat to stash in your freezer. Despite its impressive presentation and flavor, it’s often overshadowed by more hyped desserts in Costco’s bakery section. If you’re looking for a sophisticated sweet that doesn’t require hours of prep, this cake is a hidden gem worth seeking out. Slice it up, and watch it disappear faster than you can say “Kirkland.”
6. Kirkland Signature Sliced Roast Beef
Cold cuts might not sound exciting, but Kirkland Signature Sliced Roast Beef is a lunchtime MVP that’s criminally underrated. At roughly $10.49 per pound (with packages averaging $13.90 for 1.3 pounds), this tender, flavorful roast beef is a steal compared to deli counter prices or pre-packaged brands like Boar’s Head. It’s perfect for sandwiches, wraps, or even a quick protein-packed snack with crackers. Shoppers often gravitate toward Costco’s rotisserie chicken or frozen meats, leaving this gem in the refrigerated section unnoticed. The beef is lean, well-seasoned, and free of the artificial aftertaste you sometimes get with lesser brands. Stock up, and you’ll wonder why you ever paid more for lunch meat elsewhere.
7. Kirkland Signature Imported Basil Pesto
Pesto can transform a dish, and Kirkland Signature Imported Basil Pesto is a standout that doesn’t get enough buzz.
Retailing for around $10 for a 22-ounce jar, this vibrant sauce is made with Italian basil, Parmesan, pine nuts, garlic, and olive oil—delivering authentic flavor at a fraction of the cost of specialty brands. It’s incredibly versatile: toss it with pasta, spread it on sandwiches, or use it as a pizza base. While Costco’s marinara and alfredo sauces often steal the spotlight, this pesto quietly outshines them with its fresh taste and generous portion size. Pro tip: freeze leftovers in ice cube trays for easy portioning later. If you’ve been overlooking this jar in favor of pricier alternatives, it’s time to give it a whirl.
8. Kirkland Signature Flex-Tech 13-Gallon Trash Bags
Trash bags might not inspire excitement, but Kirkland Signature Flex-Tech 13-Gallon Trash Bags are a household essential that deserve more recognition. Priced at around $20 for a 200-count box (just 10 cents per bag), these sturdy bags offer durability that rivals top brands like Glad or Hefty—at half the price. They’re designed with stretchable material to prevent rips, even when stuffed with heavy or sharp waste. Shoppers often stick to name-brand trash bags out of loyalty, but these Kirkland bags prove you don’t need to splurge for reliability. Whether you’re tackling kitchen cleanup or a big garage purge, these bags have you covered. Don’t let their mundane purpose fool you—they’re a quiet superstar.
9. Kirkland Signature Five-Cheese Tortelloni with Parmigiano Reggiano
Pasta night gets an upgrade with Kirkland Signature Five-Cheese Tortelloni with Parmigiano Reggiano, a refrigerated gem priced at around $11 for a 24-ounce package. These plump tortelloni are stuffed with a blend of five cheeses, including the coveted Parmigiano Reggiano, and cook up in minutes for a quick, satisfying meal. Pair them with a simple sauce or broth, and you’ve got comfort food that feels gourmet. While Costco’s frozen lasagna and ravioli often dominate the pasta conversation, this tortelloni is a sleeper hit that delivers on flavor and convenience. It’s perfect for busy weeknights or when you want to impress without the effort. Grab a pack, and you’ll see why it’s a hidden favorite among Kirkland fans.
10. Kirkland Signature Supreme Cauliflower Crust Pizza
For those seeking a healthier pizza option, Kirkland Signature Supreme Cauliflower Crust Pizza is an underrated winner. Priced at around $12 for a 19.4-ounce pie, this frozen pizza features a sturdy cauliflower crust topped with veggies, sausage, pepperoni, and cheese. It’s a flavorful alternative to traditional pizza that doesn’t skimp on satisfaction, yet it’s often overlooked in favor of Costco’s take-and-bake options or name-brand frozen pies. The crust holds up well, avoiding the sogginess that plagues some cauliflower-based pizzas, and the toppings are generous. At 900 milligrams of sodium per quarter pie, it’s not the lightest meal, but as an occasional treat, it’s a guilt-free indulgence. Add it to your freezer stash—you won’t regret it.
