What does Costco brine their rotisserie chicken with?

The Popularity of Costco’s Rotisserie Chicken

Costco’s rotisserie chicken is one of their most popular prepared food items. Many customers love the juicy, tender chicken that comes hot out of the oven at just $4.99 for a nearly 3 pound bird. It’s easy to see why when you compare to grocery stores where rotisserie chickens can cost $8-10 for a smaller portion. Costco sells over 60 million rotisserie chickens every year! With numbers like that, it’s clear people love Costco’s rotisserie chicken. But why exactly is it so delicious? The answer lies in how Costco brines their birds before cooking.

The Secret is in the Brine

Brining is the process of soaking meat in a saltwater solution before cooking. This helps keep the meat incredibly moist and infuses it with extra flavor. While many grocers simply use a basic salt and water mixture, Costco takes their brine a step further for maximum juiciness. They soak their chickens in a proprietary blend of water, salt, sugar, and sodium phosphate for at least 8 hours before rotisserie cooking. The blend of ingredients helps the chicken retain moisture and gives it a delicious, savory flavor.

The Purpose of Each Brining Ingredient

Water – The base of any brine is water. Water helps the salt and sugars permeate through the meat.

Salt – Salt is a natural flavor enhancer and helps the chicken retain moisture.

Sugar – Sugar balances out some of the harsh saltiness and gives the chicken a touch of sweetness.

Sodium Phosphate – This is likely the secret ingredient that sets Costco’s brine apart. Sodium phosphate is a natural ingredient that helps meat retain moisture and prevents it from drying out.

How the Brining Process Works

Brining chicken is effective for two reasons: osmosis and denaturation.

Osmosis – When the chicken is soaked in the salty brine, the salt draws moisture out of the cells through osmosis while simultaneously drawing the seasoned water into the meat. This allows the chicken to absorb more moisture than usual.

Denaturation – The salt also denatures the proteins in the meat, which makes the proteins hold onto more water as they cook.

Together, these two effects create an incredibly moist and flavorful chicken. The sodium phosphate enhances the effect further.

How Costco Rotisserie Chickens Are Made

Here is an overview of Costco’s rotisserie chicken process:

  1. Whole chickens are delivered fresh, never frozen, from trusted suppliers.
  2. The chickens are seasoned and then placed into a large vat of proprietary brine solution.
  3. They soak in the brine for at least 8 hours to fully absorb the flavors.
  4. Workers drain the chickens, truss them, and skewer them onto rotisserie spikes.
  5. The chickens slowly rotate on the rotisserie oven for about an hour until fully cooked.
  6. They are removed from the oven, allowed to rest for a few minutes, then packaged and sold hot and ready to eat.

As you can see, the brining process is vital for giving Costco’s rotisserie chicken its signature flavor and juiciness.
