Demystifying Canned Tuna – How Many Cups in a Can?

Canned tuna is a pantry staple for many. It’s budget-friendly shelf-stable and versatile enough to use in salads, sandwiches, casseroles and more. But one question that often arises is – just how much tuna is actually in that little can? Read on as we break down the common canned tuna sizes and reveal exactly how many cups you get per can.

Typical Canned Tuna Sizes

Canned tuna is most commonly available in 5 ounce and 6 ounce cans. You can also find small 3 ounce cans or larger 12 ounce cans. Albacore “white” tuna is generally only sold in 6 ounce and 12 ounce sizes.

The amount of tuna in each can does vary slightly between brands. But here is an approximate breakdown of canned tuna cup measurements:

• 3 ounce can = 1/3 cup tuna
• 5 ounce can = 1/2 cup tuna
• 6 ounce can = 2/3 cup tuna
• 12 ounce can = 1 1/4 cup tuna

So if a recipe calls for 1 cup of tuna you would need approximately two 6 ounce or two and a half 5 ounce cans. For tuna casseroles salads for a crowd, tuna melts and more, opt for the 12 ounce cans to get over a cup of tuna in one can.

Know Your Tuna Types

There are a few main varieties of canned tuna:

Chunk Light Tuna – This is made from smaller, younger tuna like skipjack. The chunks tend to be smaller and more uneven. It has a milder flavor than white tuna. Chunk light is typically canned in water or oil.

Flaked/Shredded Light Tuna – This consists of tiny shreds of light tuna meat. Flaked tuna contains more water than chunk style. It has a soft texture so works well in tuna salad or casseroles.

Chunk White Albacore Tuna – Albacore is larger tuna that produces thick, meaty chunks. The chunks are uniform in size and shape. White tuna has a richer, brinier flavor. It’s pricier than light tuna.

Solid White Albacore Tuna – This is premium quality tuna where the chunks are cut from loins of tuna and carefully placed in the can. There are no irregular pieces or flakes. It has the best flavor and texture but costs more.

Does Brand Make a Difference?

When it comes to canned tuna, brand can make a difference in quality, flavor, sustainability practices and more. Some factors to consider:

Chunk vs Flake – Less expensive brands often use flaked or shredded tuna which contains more water weight. Premium brands use solid chunks which equates to more edible tuna per can.

Fillers – Some brands mix in other fish like herring to cut costs. Check the ingredients list for 100% tuna.

Catch Method – Brands using pole & line caught tuna help reduce bycatch impact on other marine life.

Mercury Levels – Smaller tunas like skipjack have lower mercury levels than large tunas. Check if the brand tests mercury levels.

Flavor – Higher quality tuna has a pleasant briny flavor. Lower quality tuna can have a fishy taste.

While it often costs a dollar or two more per can, purchasing a reputable brand ensures you get quality, sustainable tuna with better flavor.

Get the Right Tuna-To-Recipe Ratio

One key to avoiding tuna mishaps is understanding how much tuna you need for your desired recipes. Here are some tuna can guidelines for popular recipes:

• Tuna salad – 5 to 6 oz can per 3/4 to 1 cup salad
• Tuna melts – 6 oz can per 2 sandwiches
• Tuna casserole – 12 oz can for a 9×13 pan; 2 cans for larger dish
• Tuna patties – 1 can makes 3 to 4 patties
• Tuna noodle bake – 12 oz can for 8″ baking dish
• Tuna cakes – 1 can makes 3 medium or 2 large cakes

Buy and open accordingly to get the right tuna-to-recipe ratio. While you can work with less tuna in some cases, resist trying to stretch cans too far or the tuna flavor and protein content will get diluted.

Know When To Use Water vs Oil Packed

Canned tuna packed in water has slightly fewer calories and fat than oil-packed. But both versions are healthy, with protein as the main nutrient. Here are some guidelines on when each works best:

• Water packed – Use for tuna salads, sandwiches, melts, casseroles, pasta dishes and anywhere you want to control calories and fat content.

• Oil packed – The oil helps tuna hold moisture during canning. Use oil-packed for tuna patties, cakes or anywhere you want added moisture and flavor.

• Recipes with acidic ingredients – Oil-packed works best for recipes with acidic ingredients like lemon juice, vinegar or tomatoes as the oil helps prevent the tuna turning mushy.

Either type of canned tuna can be rinsed to reduce sodium levels. Water packed can be drained before use to remove excess water if desired.
