Costco Kirkland Signature Lean Sirloin Beef Patties Review

Costco has two different kinds of Kirkland Signature beef patties: the uncooked lean sirloin patties, and the uncooked lean ground beef patties. Which one is healthier? More flavorful? Cheaper? Today I’m covering everything you need to know about the Costco sirloin burgers!

My favorite burgers in the world are my mom’s homemade burgers. Unfortunately, neither my husband nor I make burgers from scratch, so these Costco Kirkland Signature Uncooked Lean Sirloin Beef Patties are our go-to hamburger patties when we barbecue burgers at home.

Other burgers from Costco are the Costco Kirkland Signature Lean Ground Beef Patties, Costco Beyond Meat Burgers, Costco Trident Wild Pacific Pink Salmon Burgers, Costco The Keg Prime Rib Beef Burgers and the Costco Kirkland Signature Chicken Burger Meal Kit.

Location in Store

You can find the frozen burgers at Costco in the freezer aisle, near the frozen chicken wings. The item number is 296549.

Taste

The sirloin beef burgers from Costco have one ingredient, sirloin beef. Yep, that’s it. No salt, no fillers, no seasoning. The lack of fillers and seasonings isn’t a problem in my opinion because the patties use high-quality sirloin beef. Another advantage of the simplicity of these burgers is that you can season them to your taste. I add a bit of seasoning and sometimes some barbecue sauce as well.

You probably do need to season these burgers, because they’ll taste a bit bland if you don’t. I don’t taste a ton of fat in the Kirkland Signature Lean Sirloin Beef Patties, but there’s enough in my opinion. I’ve never found them dry (unless it was from us overcooking them!). Finally, I don’t think they contain as much gristle or random hard chunks as some other frozen burgers seem to. The meat is consistently good quality.

How amazing does this burger look?!

I’ve tried the Costco Kirkland Signature Lean Ground Beef Patties and I much prefer these lean sirloin patties. They’re a little less flavorful out of the bag, but there’s less gristle and fat for sure.

Cost

For $26.99, you get 18 Costco Kirkland Signature Lean Sirloin Beef Patties.

Convenience

The patties come in a bag and the patties are stacked one on top of the other with paper in between. If you want to just cook one burger for yourself, you totally can. Unfortunately, I have found the burgers can freeze together pretty badly sometimes. It can be hard to get the right number out, but careful yet forceful use of a butter knife usually gets the job done.

Each burger is one-third of a pound!

You have to season and cook these burgers as they don’t come pre-seasoned or pre-cooked. With that being said, hamburgers aren’t exactly the hardest food to cook! The burger patties need to be kept frozen and the best before date is about eight months from the date we purchased them. Another small negative is that the bag isn’t resealable, so you’ll need to tie off your bag or transfer your burgers to an airtight container before you put them back in your freezer.

Nutrition

Calories

Eating burgers every day is probably not the best thing for you nutritionally. One patty contains 320 calories, 22 grams of fat, three grams of carbohydrates, zero grams of fibre, zero grams of sugar and 26 grams of protein.

Ingredients

There’s only one ingredient in these burgers: sirloin beef. For that reason, these burgers are a healthier choice than some store bought frozen burgers. One benefit of them being unseasoned is that you can easily control how much sodium is in your burger. You can also limit the calories a bit by choosing what you put on your burger. You can even use lettuce as a bun if you’re super health-conscious! Personally, my favorite buns to use are the Costco Kirkland Signature Italian Ciabatta Buns. The fat may seem a little high, but any beef product usually has higher amounts of fat. Some of it cooks off when you barbecue the burgers (or so I tell myself).

Overall

Must buy!

I think the Costco sirloin burgers are perfect to serve at a summer barbecue or to bring camping! Whenever I see them, I always think of summer and barbecue season. These burgers are in our freezer every summer and both my husband and I really enjoy them.

  1. Well we use a butter knife some times to help separate them. If they won’t come apart like that then they may have thawed out and re-frozen somewhere along the line? I would return them and try again with a fresh package that looks better. We thaw ours out usually before barbequing and season with Montreal steak spice, They taste like meat without all the fillers in most other premade burgers.
    Never had a bad experience, however if we did they would go right back to Costco, who are always happy to take returns, if there is an issue.
    They are the only frozen burgers we buy, otherwise we also make some of our own.

  2. I have tried these, but find they fall apart on the grill to easy. They do taste a bit better than the lean burgers, but when they go through the grate, they’re gone.

  3. It is odd that a product made supposedly one ingredient (beef) could have 3 grams of carbohydrate. There are zero carbohydrates in beef. None.

    ThisThis is really worth checking into, and I’m going to do just that.

  4. We have purchased these burgers many times and still do. Taste is great, no problem in separation and grills up great. They go camping with us all the time.

  5. I saw these in the store and passed on them when I saw the ingredients. If they are 100% beef, I don’t understand how they can have 3 grams of carbohydrates.

    • It’s probably on over estimate? Some websites do show 2 carbs for 6 oz of sirloin beef. I am more skeptical about the websites that say there are no carbs in beef no mater how large a portion you enter in the calculator? Meat has very little carbs but it does hove some. We eat these during keto with no problems.

  6. Didn’t even get to cook them. They were completely frozen together, tried everything to separate them,
    they should have double parchment between each one. Am going to return them Ridiculous.

    • So we’ve had this before, usually it’s a sign they’ve thawed and been refrozen. The bags we bring home quick or in cooler weather or not as bad. I’d return and try another bag.

      • Yes that’s what I told Costco Costco told me that they have not heard any bad things on this meat I find that hard to believe So we’re getting meat that was old because this is November and you eat them in August

      • I can’t believe the negative comments on the sirloin burgers. I have purchased dozens of bags of them and have NEVER had a bad one. They are so convenient if you don’t have dinner plans. Just take out of the freezer and throw them on the grill. A little montreal season and you are good to go.
