Costco is known for its bulk deals and popular items, but there are numerous hidden gems that even seasoned shoppers might overlook. From gourmet food items to practical everyday essentials, these overlooked products offer quality and value that are hard to beat. Dive into our selection of great Costco buys that deserve a spot in your shopping cart.
Ground beef is incredibly versatile and the grass-fed stuff from Costco is high quality without the premium price tag you'd pay at specialty stores. A 4-ounce cooked portion gives you around 28 grams of protein, and you can use it for burgers, tacos, spaghetti sauce, chili, or whatever else you're making. Grass-fed beef has a slightly different flavor than regular beef - it's a bit leaner and some people say it tastes more "beefy" - but I think it's better. It comes in these big packages at Costco, so I divide it up into portions and freeze what I'm not using right away. Just write the date on the freezer bags so you know how long it's been in there. The main thing with ground beef is making sure you cook it to the right temperature, especially if you're making burgers. Nobody wants to deal with food poisoning. I use a meat thermometer now and cook it to 160 degrees internal temperature. It seems like overkill, but it's worth it for peace of mind.
Peanut butter might not seem like a protein powerhouse, but it's actually got 7-8 grams per 2-tablespoon serving, plus healthy fats that keep you full. The Kirkland organic version is just peanuts and salt - no added sugar or oils like the regular brands. It's a bit thicker and you have to stir it since the oil separates, but once you get used to it, the sugary stuff tastes artificial. I spread it on whole wheat toast in the morning, throw a spoonful in my protein shake, or just eat it straight off the spoon when I need a quick snack. The jars are huge at Costco, so you're set for a while. Just remember that while it's healthy, it's also calorie-dense, so don't go crazy with portion sizes. A serving is 2 tablespoons, and most guys pour out way more than that without realizing it. I actually started measuring it out, and I was using like 4-5 tablespoons at a time before, which is over 500 calories just from peanut butter.
Eggs are pretty much the perfect protein source, and Costco sells them in massive quantities for way less than regular grocery stores. Each egg has about 6 grams of protein, and contrary to what people used to think, eating eggs every day is perfectly fine for most people. I go through two or three dozen a week easy - scrambled eggs for breakfast, hard-boiled eggs as snacks, fried eggs on burgers, you name it. The cage-free ones from Kirkland cost a bit more than the regular eggs, but the yolks are darker and they taste better, so it's worth it in my opinion. Keep a bunch of hard-boiled eggs in your fridge and you've always got a quick protein hit when you need it. They last about a week in the shell after you boil them. Some people only eat the whites to avoid the fat and cholesterol, but the yolk is where most of the nutrients are, so unless your doctor specifically told you otherwise, eat the whole thing.
Salmon is one of those foods that's expensive everywhere except Costco, where you can get frozen filets for a reasonable price. Each 6-ounce serving has around 40 grams of protein, plus it's loaded with omega-3 fatty acids that are supposed to be great for your heart and brain. The frozen wild-caught stuff from Kirkland is solid quality - it doesn't have that weird mushy texture you sometimes get with cheaper frozen fish. I keep a bag in the freezer and pull out a couple filets the night before I want to cook them. You can bake it, grill it, or pan-sear it with just some salt, pepper, and lemon, and it's delicious without needing fancy sauces or complicated recipies. The wild-caught version costs more than farm-raised, but it tastes cleaner and doesn't have the same concerns about antibiotics and stuff. If you're not used to cooking fish, salmon is pretty forgiving - just don't overcook it or it'll get dry.
This isn't your regular yogurt - Greek yogurt is strained differently so it's thicker and has way more protein. The Kirkland version comes in big tubs, and each cup serving gives you around 18-20 grams of protein depending on whether you get the plain or flavored varieties. I go with the plain because the flavored ones have more sugar, and I just add my own berries or a little honey if I want it sweeter. It's great for breakfast, obviously, but I also use it in place of sour cream on tacos or baked potatoes. Some guys mix it with protein powder for an extra boost, but honestly it's got plenty on its own. The texture takes a minute to get used to if you're coming from regular yogurt, but once you do, the regular stuff tastes watery and boring. Just make sure you're actually getting Greek yogurt and not regular yogurt labeled as "Greek style" because that's a different thing with less protein.
Fresh milk at a good price is harder to find than it should be, but Costco delivers. The organic milk comes in multi-packs, and while that seems like a lot, the expiration dates are usually pretty far out, so it keeps well. It tastes clean and fresh, not like it's been sitting around forever, and knowing it's organic matters to people who care about hormones and additives. Whether you're drinking it straight, putting it in coffee, or using it for cereal, having quality milk on hand is essential. The price per gallon beats the regular grocery stores, especially for organic, and you're not sacrificing quality for savings.
Real maple syrup snobs know that once you go genuine, you can't go back to the fake stuff, and Costco's organic version delivers premium quality without the premium price tag. This isn't some watered-down imitation - it's the real deal from Canada, thick and rich with that authentic maple flavor that makes pancakes and waffles actually worth eating. The big jug lasts ages even if you're pretty generous with your pour, and it's perfect for more than just breakfast. People use it in marinades, glazes, coffee, and baking. The depth of flavor compared to conventional syrup is night and day, and once your family tastes the difference, they'll revolt if you try switching back to save a few bucks.
When it comes to paper towels, the Kirkland brand holds its own against the big names but costs way less per sheet. These aren't the flimsy ones that fall apart the second they touch water - they're thick, absorbant, and actually get the job done. A pack lasts forever, even in a busy household with kids and pets. People rave about how they handle spills, clean windows, and don't leave behind lint like cheaper brands do. The sheets are a good size too, not those tiny ones that make you use half a roll for one mess. Stock up on these and you won't have to think about paper towels again for months. They're also great to keep in the garage for car projects or messy outdoor work since they're tough enough to handle grease and grime without shredding.
The protein bar market is crowded and expensive, but Costco's house brand has carved out serious loyalty by delivering taste and nutrition without the premium pricing. These actually taste good unlike so many protein bars that have the texture of cardboard, and they pack enough protein to actually be useful for post-workout recovery or meal replacement. The variety pack keeps things interesting, and the value compared to buying name brands individually is almost comical. They've become gym bag staples, desk drawer essentials, and road trip fuel for people who want convenient nutrition that doesn't taste like punishment. Once people try them, the switch from expensive brands happens pretty much immediately.
This isn't the boxed stuff you remember from college – it's actual macaroni in a rich, creamy cheese sauce that tastes indulgent without being too heavy. The tray is big enough to serve as a side for several meals or as a main dish if you're really hungry. You can eat it as is, or jazz it up with some bacon bits, breadcrumbs on top, or mix in some leftover chicken or vegatables to make it more of a complete meal. It heats up quick in the oven and comes out bubbly and golden. Mac and cheese is one of those comfort foods that just hits different when it's cold outside, and this version delivers that cozy feeling without you having to make a roux or shred a pound of cheese. It's the kind of meal that makes you feel satisfied and content after a tough day.
For the value hunters, this one's a winner straight from Costco's house brand—100% Colombian beans in a medium-dark roast that delivers full-bodied richness with subtle caramel sweetness. It's bold enough to stand up on its own but not overwhelming, with a clean taste that shines in drip or French press. Experts appreciate how fresh it often is in bulk bags, and it's a go-to for stocking up without breaking the bank. If you're buying in bigger quantities for the house or garage coffee station, this hits that sweet spot of quality and quantity every time. Buy it now!
The clothing section is a hidden gem, and the Kirkland Travel Pants are a favorite for their durability and comfort. With four-way stretch fabric and five pockets, employees compare them to high-end athletic brands, making them a practical choice for active lifestyles.
