A standard 5-ounce can of chicken breast contains roughly 32 grams of protein. That’s about the same as a palm-sized piece of fresh cooked chicken, packed into a shelf-stable can. The exact number shifts depending on the can size, the brand, and whether the chicken is packed in water or broth.
Protein by Can Size
Canned chicken comes in a few common sizes, and the protein content scales accordingly. A 5-ounce can, the most common single-serving size, delivers about 32 grams of protein from the entire can. Per ounce of drained chicken, you’re getting roughly 6 grams of protein, based on USDA data for cooked canned white meat chicken.
Larger cans, like the 12.5-ounce size sold by brands such as Great Value, typically contain multiple servings. These list around 18 to 21 grams of protein per serving, with a serving size of about 2 ounces drained. If you eat the whole large can, you’re looking at somewhere around 50 to 60 grams of protein total, though this varies by brand and how much liquid is in the can.
The key detail: always check whether the label lists protein for drained chicken or for the entire contents including liquid. The broth or water adds weight but not meaningful protein. Drain the can before estimating your intake.
How Canned Chicken Compares to Fresh
Canned chicken is lower in protein per ounce than a freshly cooked chicken breast. Three ounces of fresh cooked chicken breast provides about 26 grams of protein, while three ounces of canned chicken delivers around 15 to 21 grams, depending on the brand and packing liquid. That’s a noticeable gap.
The difference comes down to water content. Canned chicken absorbs liquid during processing, which dilutes the protein density by weight. You’re not losing protein in a nutritional sense. You’re just getting more moisture per bite. If you drain the chicken thoroughly and press out excess liquid, you’ll close that gap somewhat. But ounce for ounce, fresh chicken breast will always pack more protein.
Canned Chicken vs. Canned Tuna
If you’re choosing between canned proteins for efficiency, the comparison is worth knowing. Three ounces of drained canned chicken provides about 21 grams of protein and 150 calories. Three ounces of canned light tuna comes in at about 16 grams of protein and only 77 calories.
So canned chicken has more total protein per serving, but canned tuna is significantly leaner. Per calorie, tuna gives you more protein for less energy. If you’re trying to hit a protein target while keeping calories low, tuna wins. If you simply want the most grams of protein in a single can, chicken is the better pick.
What Else Is in the Can
Canned chicken isn’t just protein. Most brands add salt during processing, and sodium levels can be substantial. A full 5-ounce can often contains 400 to 600 milligrams of sodium, though this varies widely. Low-sodium versions exist and typically cut that number in half or more. If you’re watching salt intake, check the label rather than assuming all canned chicken is the same.
Fat content depends on whether the chicken is white meat only or a mix of white and dark. Canned chicken breast (white meat) runs about 6 to 7 grams of fat per can in the 5-ounce size. Mixed varieties or chicken packed in oil will be higher. Most canned chicken contains zero carbohydrates.
Getting the Most Protein From a Can
A few practical tips if you’re using canned chicken as a protein source. Drain it well. The packing liquid adds weight but almost no protein, so leaving it in just waters down your meal. Some people press the drained chicken with a paper towel to remove even more moisture, which concentrates the protein per bite.
Brands labeled “chunk chicken breast” or “white meat only” consistently have more protein than those labeled “chicken” generically, which can include dark meat, skin, or other parts. The ingredient list should be short: chicken, water, salt. Anything beyond that is filler that displaces protein.
For meal planning, one 5-ounce can at roughly 32 grams of protein covers about half the daily protein target for a 150-pound adult aiming for the common recommendation of 0.7 to 1 gram per pound of body weight. Two cans a day would get most people close to their full protein needs, though variety in protein sources is generally a better strategy for overall nutrition.
