Choosing the right frozen burger can be a grilling game-changer, especially when stocking up at Costco. Kirkland Signature offers two main contenders in the frozen burger aisle: their Sirloin Burgers and Grass Fed Burgers. Both promise convenience and a satisfying burger experience, but with key differences. If you’re standing in the freezer section, scratching your head, wondering which bag to toss in your cart, you’re in the right place.
Having cooked and tasted both Kirkland Signature frozen burger varieties, I lean towards recommending the Sirloin Burgers for most people. But the best choice for you depends on your priorities. Let’s dive into a detailed comparison to help you decide whether to go with the value and taste of the Sirloin or the potential environmental edge of the Grass Fed.

Kirkland Signature Frozen Burgers: Sirloin vs. Grass Fed – What’s the Difference?
Costco keeps it straightforward with two primary types of their Kirkland Signature frozen burger patties: Sirloin and Grass Fed. Understanding the nuances between these two is key to making the best decision for your next barbecue or quick weeknight meal.
Kirkland Signature Sirloin Frozen Burgers
The Kirkland Signature Sirloin Burgers are made with an 85% lean and 15% fat blend. This balance aims for a juicy burger without excessive grease. Each bag contains 18 individual patties, each weighing in at a substantial 1/3 pound. This bulk packaging makes them ideal for families, parties, or anyone who enjoys having burgers on hand. Sirloin, known for its robust beef flavor, typically translates to a satisfyingly classic burger taste.
Kirkland Signature Grass Fed Frozen Burgers
For those leaning towards potentially more sustainable or health-conscious options, Costco offers Kirkland Signature Grass Fed Frozen Burgers. These patties have a slightly different lean-to-fat ratio of 80% lean and 20% fat. Interestingly, despite the “grass fed” label often associated with leaner beef, these burgers are actually fattier than their sirloin counterparts. A bag of Grass Fed burgers contains 15 patties, also 1/3 pound each.
The term “grass fed” indicates that the cattle were raised primarily on pasture and forage diets. While all cattle may start on grass, conventionally raised beef often spends their final months in feedlots, fattened up on grains like corn. Grass-fed beef is often touted for potential environmental benefits, although the complete picture of environmental impact is complex and debated. Some also believe grass-fed beef offers health advantages, like a different fatty acid profile. However, as we’ll explore in the nutrition section, the Kirkland Grass Fed frozen burgers might not deliver the expected nutritional edge.
How to Cook Costco Frozen Burgers: Grilling and Pan-Frying
Cooking frozen burgers doesn’t have to be complicated. Both the Kirkland Signature Sirloin and Grass Fed burgers are designed to be cooked directly from frozen – no thawing required! This is a major convenience factor for quick meals.
Cooking in a Cast Iron Skillet (or Pan): This is a great method for achieving a flavorful crust.
- Heat a skillet: Place a cast iron skillet (or heavy-bottomed pan) over medium heat. Add a pat of butter or a tablespoon of oil.
- Sear the burgers: Once the pan is hot, place the frozen burger patties in the skillet. Don’t overcrowd the pan; cook in batches if necessary.
- Cook and flip: Cook for approximately 4-5 minutes per side, or until juices begin to surface on the top of the burger. Season the cooked side with salt and pepper before flipping.
- Check internal temperature: Continue cooking for another 4-5 minutes, or until the internal temperature reaches 165°F (74°C) as measured with a meat thermometer.
Grilling Frozen Burgers: Grilling adds smoky flavor, perfect for burgers.
- Preheat grill: Preheat your grill to medium heat.
- Grill burgers: Place frozen patties directly on the grill grates.
- Cook and flip: Grill for about 5-7 minutes per side, flipping once, until cooked through and grill marks appear. Ensure the internal temperature reaches 165°F (74°C).
Flavor Boost Tip: While the burgers cook, consider adding sliced mushrooms or onions to the pan (or grill in a foil packet). Sautéing them with a dash of Worcestershire sauce elevates the burger experience. Adding cheese during the last minute of cooking and toasting your burger buns in the pan drippings (or on the grill) takes it to another level.

Calorie and Nutrition Comparison: Kirkland Signature Grass Fed vs. Sirloin Frozen Burgers
It’s a common assumption that grass-fed beef is automatically healthier. However, when comparing Kirkland Signature’s frozen burger options, the nutritional labels tell a slightly different story.
The key factor here is the lean-to-fat ratio. Despite the “grass fed” label, the Kirkland Grass Fed burgers have a higher fat content (80/20 grind) compared to the Sirloin burgers (85/15 grind). This difference directly impacts the calorie and fat content per patty.
Here’s a side-by-side nutritional breakdown per patty:
- Kirkland Signature Grass Fed Frozen Burger: 380 calories, 30 grams of fat, 26 grams of protein
- Kirkland Signature Sirloin Frozen Burger: 320 calories, 23 grams of fat, 28 grams of protein
As you can see, the Sirloin burgers actually contain fewer calories and less fat, while providing slightly more protein per serving. Therefore, if you are watching your calorie or fat intake, the Sirloin option is nutritionally leaner. The perceived health benefits often associated with grass-fed beef might be less pronounced in these particular frozen burger patties due to the higher fat percentage in the Grass Fed version.
Price and Value: Which Costco Frozen Burger is the Better Buy?
Price is always a factor, especially when buying in bulk at Costco. Let’s compare the cost-effectiveness of these frozen burger options.
As of the latest pricing (prices may vary by location and time), the approximate costs are:
- Kirkland Signature Grass Fed Frozen Burgers: Around $24 for a 5-pound bag containing 15 patties. This breaks down to approximately $1.60 per patty.
- Kirkland Signature Sirloin Frozen Burgers: Around $26 for a 6-pound bag containing 18 patties. This comes to roughly $1.50 per patty.
Surprisingly, the Sirloin burgers are not only nutritionally comparable (and in some ways, leaner) but also slightly less expensive per patty. This makes the Kirkland Signature Sirloin Frozen Burgers a compelling value choice.
Final Verdict: Sirloin or Grass Fed Costco Frozen Burgers?
For most Costco shoppers looking for delicious, convenient, and budget-friendly frozen burgers, the Kirkland Signature Sirloin Frozen Burgers emerge as the top recommendation. They offer great flavor, a slightly leaner nutritional profile, and are more economical per patty.
However, if grass-fed beef and its potential (though debated) environmental benefits are a significant priority for you, the Kirkland Signature Grass Fed Frozen Burgers are still a decent option. Just be aware that in this specific comparison, they are not leaner or lower in calories than the Sirloin burgers.
Ultimately, both Kirkland Signature frozen burger options at Costco are solid choices for stocking your freezer. Consider your priorities – value, taste, nutrition, or environmental considerations – to decide which burger best fits your needs. Either way, you’re just minutes away from a satisfying burger meal!
