What Is That White String in Chicken Tenders? Plus, Is It Safe to Eat and How to Easily Remove It

Chicken is one of the healthiest protein choices you can make when deciding what to cook for dinner. And chicken breast boasts great flavor with minimal internal fat, making it low in calories and still high in protein. But if you have not worked with chicken a lot, you might notice while prepping that there is a white stringy thing in the chicken breast. And you may wonder if you should remove it or if it is safe to eat.

What Is That White String in the Chicken Breast and Is It OK to Eat?

The white string you see in your chicken is just a tendon. The tendon is connective tissue that helps the muscles attach to the bones, just like the tendons we have! It is entirely edible and not dangerous to consume, but it can get a bit tough or rubbery when cooked, so it is up to you whether you want to remove it or not when prepping your chicken.

What Part of the Chicken Is the Tender?

Some people think that chicken tenders are just strips cut from the breast of the chicken. But in fact, the tender or tenderloin is an independent secondary muscle that lies directly under the breast. Sometimes, the whole breast is removed, which includes the tender; sometimes they are removed separately. The tender contains the visible portion of the tendon that looks like a string.

How to Remove a Tendon from a Raw Chicken Tender or Breast

The tendon in chicken breast meat runs down the center of the tender and can be removed whether you are leaving the tender attached to the breast or not. To remove the tendon:

• Place the breast (or tender) skin-side up on a cutting board, with the pointy end toward you.
• Using a paper towel, pinch the white end of the tendon firmly between your fingers and place your chef's knife at a 30-degree angle, trapping the tendon between the knife and your cutting board.
• Slowly, holding the tendon firmly, wiggle the knife back and forth to reveal more of the tendon, and get a better grip on it. Once you have a solid grip on the first inch or so of the tendon, you should be able to hold it firmly and slide the angled knife against the board to cut the tendon out without damaging the meat.

Alternatively, you may also place the tendon between the tines of a fork, grip the tendon with a paper towel, and slowly pull it out of the chicken while pushing the fork downward, opposite to the direction you're pulling the tendon. The tendon will slide right out, as seen in this viral TikTok video from @raerae738 (we tried it too, and it worked!).

Do I Have to Remove the Tendon from Chicken?

You do not need to remove the tendon from the chicken. The tendon is perfectly edible and not at all dangerous. Removing the tendon is often either an aesthetic decision or done because tendons can be tough and rubbery when cooked.

What Happens to a Tendon When the Chicken Cooks?

Tendons are essentially like straps that attach muscle to the bones of the chicken. This connective tissue is very strong. When you cook it, the tendon firms up and contracts, making it slightly tougher than the surrounding meat, which is why some chefs choose to remove it before cooking. For home cooks, it can often be easier to simply eat around the tendon or remove it after cooking.

The Bottom Line

If you love chicken breasts but hate that rubbery band, it isn't hard to learn how to remove it before cooking. But if it doesn't bother you, you can be assured that it's not dangerous to eat!
