How many calories are in an 8 oz sirloin steak grilled?

An 8 ounce sirloin steak that has been grilled contains approximately 300-375 calories depending on the cut and fat marbling. Sirloin steak is a leaner cut of beef that contains less fat than other cuts like ribeye or T-bone steak. Because it is a leaner cut, an 8 ounce sirloin steak will have fewer calories than fattier cuts of steak.

Calorie range for 8 oz grilled sirloin steak

The exact calorie count for an 8 oz sirloin steak that has been grilled can vary due to a few factors:

  • Cut of sirloin – Top sirloin has the lowest fat content and calorie count while bottom sirloin has slightly more fat and calories.
  • Degree of marbling – The more white fat marbled throughout the meat, the higher the calorie count will be.
  • Cooking method – Grilling tends to allow some fat to drip away, lowering the calories versus pan frying.
  • Portion size – An 8 oz steak may vary slightly in its exact weight and thickness, altering the calories.

Taking into account these factors, a typical 8 ounce top sirloin steak that has been grilled will contain approximately 300-350 calories. A more marbled cut like bottom sirloin may contain 325-375 calories for an 8 ounce portion.

Calories by cooking method

The method used to cook a sirloin steak impacts its final calorie content. Here is how the calories compare for an 8 oz sirloin steak depending on how it is cooked:

  • Grilled: 300-375 calories
  • Pan-fried: 350-400 calories
  • Broiled: 325-400 calories
  • Baked: 300-375 calories

Grilling and broiling allow excess fat to drip away from the meat, resulting in a lower calorie count. Methods like pan frying or baking keep more of the fat in the final product, increasing the calories. Grilling an 8 oz sirloin steak is one of the leanest preparation methods.

Calories by doneness

How well-done a sirloin steak is cooked also impacts its calorie content. A steak cooked to a lower doneness retains more moisture and fat versus one cooked to a well-done temperature. Here are the approximate calories for an 8 oz grilled sirloin steak based on internal temperature when cooked:

  • Rare – 120°F: 300 calories
  • Medium rare – 130-135°F: 325 calories
  • Medium – 140-145°F: 350 calories
  • Medium well – 150-155°F: 375 calories
  • Well done – 160°F+: 400 calories

As the internal temperature increases, more fat renders out of the steak, increasing the calorie count slightly. A rare steak will have slightly less fat than a well-done steak.

Leanest cuts of steak

For those watching their calorie intake, sirloin, round, and loin cuts of steak tend to be the leanest options. Here are some of the most lean cuts of steak and their calorie content in a typical 8 ounce cooked portion:

  • Top sirloin – 300-350 calories
  • Bottom round – 250-300 calories
  • Eye of round – 275-325 calories
  • Top loin – 300-375 calories

High calorie additions

While a plain grilled sirloin steak is relatively lean, the way it is served and additions made can significantly increase the calorie count. Some high calorie additions to be mindful of include:

  • Butter – 100 calories per tablespoon
  • Steak sauce – 60-150 calories per 2-4 oz
  • Roasted garlic butter – 150 calories per 2 tbsp
  • Sauteed mushrooms – 50 calories per 1/2 cup
  • Loaded baked potato – 220-320 calories

A steak served with multiple sides like a potato, butter, sauce, and sauteed vegetables can end up being a very high calorie meal. Limiting high calorie extras or using lower calorie substitutions like chimichurri sauce vs steak sauce can help keep calories in check.

Portion size

In addition to calorie-dense additions, portion size has a significant impact on the overall calorie count. Here’s how the calorie count scales up or down for different portion sizes of sirloin steak:

  • 4 ounces – 200 calories
  • 6 ounces – 250-300 calories
  • 8 ounces – 300-375 calories
  • 10 ounces – 375-450 calories
  • 12 ounces – 450-525 calories
  • 14 ounces – 525-600 calories

Those watching their calorie intake may opt for a smaller 6 ounce steak versus a larger cut. Or, if cooking a larger steak, plan to share portions or save half for leftovers.

Healthiest preparation methods

To keep the calorie count of sirloin steak down, opt for the healthiest preparation methods:

  • Grilling – Allows fat to drip away, keeping calories in the 300-375 range for an 8 oz steak.
  • Broiling – Cooks the steak from above, resulting in less fat absorption.
  • Marinating – Enhances flavor without added calories.
  • Herb rubs – Boosts flavor with little to no calories.
  • Sear then bake – Searing gives flavor then baking avoids pan frying.

Additionally, stick to leaner sirloin cuts like top sirloin and choose reasonable portion sizes for the lowest calorie option.
