The phrase "Costco keg prime rib burger" refers to the popular frozen patties from The Keg Steakhouse that are often sold at Costco stores. While convenient and high-quality, it's crucial to understand that the calorie count for the patty is just one part of the total meal's nutritional information. The final tally depends heavily on how you prepare and serve your burger.
The Base Patty: Keg Prime Rib Burger Calories
When examining the nutrition for The Keg frozen patty itself, it's important to note that figures can vary slightly based on the specific version of the product available. For example, some nutritional tracking websites list The Keg's prime rib burger patty at 420 calories, while others show a slightly higher count. A gluten-free version has also been listed with 460 calories per patty. These variations can be attributed to differences in product formulation or data sources over time. The 420-calorie patty (6 oz / 170g) provides the following macronutrient breakdown:
- Total Fat: 33g
- Saturated Fat: 15g
- Trans Fat: 1.5g
- Cholesterol: 105mg
- Sodium: 830mg
- Protein: 26g

It's worth emphasizing again that this is the calorie count for the uncooked patty only, and it serves as the foundation upon which to build your total burger calorie calculation.
Building Your Burger: How Calorie Count Adds Up
To get a complete picture of your meal's nutritional impact, you must add the calories from all the additional components. The number of calories can quickly accumulate, transforming a moderate-calorie patty into a high-calorie meal. Consider the following common burger additions and their estimated calorie counts:
- Standard white bun: ~150 calories
- Brioche bun: ~240 calories
- Slice of cheddar cheese: ~113 calories
- Slice of American cheese: ~104 calories
- Slice of pan-fried bacon: ~43 calories
- Tablespoon of mayonnaise: ~90-100 calories
- Tablespoon of ketchup: ~15 calories
- Tablespoon of BBQ sauce: ~30 calories
- Lettuce/Tomato/Onion: Minimal calories (typically under 20 total)

Tips for a Healthier Keg Prime Rib Burger
For those looking to manage their calorie intake while still enjoying a delicious burger, several modifications can be made:
- Ditch the Cheese: A single slice of cheese can add over 100 calories. Skipping it or opting for a lighter, reduced-fat option can make a difference.
- Choose Your Bun Wisely: A standard bun is a decent choice, but some low-calorie, high-fiber alternatives are also available. Consider an open-faced burger to cut bread carbs and calories in half.
- Go Light on Sauces: Mayonnaise is a major calorie contributor. Consider using mustard, a calorie-free seasoning blend, or a small amount of low-fat Greek yogurt as a substitute.
- Load up on Veggies: Instead of high-calorie toppings, pile on the fresh produce like lettuce, tomatoes, and onions for flavor and volume without a significant calorie increase.
- Consider the Cooking Method: Grilling the patty instead of pan-frying it can help reduce added fat and calories.
Conclusion: The Importance of a Complete Calculation
In conclusion, asking how many calories are in a "Costco keg prime rib burger" is more complex than it appears, as the number for the frozen patty is only the starting point. While the patty itself provides a calorie baseline of roughly 420-490, the final nutritional impact is determined by the bun, cheese, sauces, and other additions. A basic build might be under 700 calories, while a fully-loaded version could easily exceed 900. By understanding the calorie contribution of each ingredient, you can make informed choices to enjoy a more balanced meal that fits your dietary needs.
