If you’ve ever shopped at Costco, chances are you’ve been tempted by the mouthwatering aroma of their famous rotisserie chickens. At just $4.99 (a price they’ve maintained despite inflation!), these golden-brown birds have developed something of a cult following. In 2022 alone, Costco sold a staggering 117 million rotisserie chickens – that’s 11 million more than the previous year!
But lately, there’s been some buzz about these beloved birds Some customers have reported a strange “chemical” taste, while others remain devoted fans. So what’s actually in these chickens, and why might some people be experiencing an off-putting flavor? Let’s dive into the ingredients, cooking process, and recent controversy surrounding Costco’s rotisserie chicken.
The Official Ingredients List
According to the most current information as of February 18, 2025, Costco’s rotisserie chicken contains:
- Fresh whole chicken
- Water
- Seasoning blend consisting of:
- Salt
- Sodium phosphate
- Modified food starch
- Potato dextrin
- Carrageenan
- Sugar
- Dextrose
- Spice extractives
That’s it! No MSG, no artificial preservatives, and it’s gluten-free (though cross-contamination during preparation is always a possibility)
Breaking Down the Ingredients
Let’s take a closer look at what these ingredients actually do:
The Chicken Itself
Costco starts with fresh, high-quality chicken. While not organic (unless specifically labeled as such), the chicken serves as the foundation for their famous rotisserie product.
In 2019, Costco actually established its own massive chicken production facility in Fremont, Nebraska, partnering with Lincoln Premium Poultry (LPP) to manage it. This vertical integration helps them maintain that $4.99 price point that customers love.
The Seasoning Components
Salt: The primary seasoning ingredient that enhances flavor.
Sodium Phosphate: This is where things get interesting. Sodium phosphate serves several purposes:
- Helps the chicken retain moisture during cooking
- Improves tenderness
- Extends shelf life
This ingredient might be partly responsible for the “chemical” taste some customers have reported. According to food science experts interviewed by Bon Appétit, some people may interpret the taste of phosphates as soapy or chemical-like – similar to how cilantro tastes like soap to certain people but delicious to others.
Modified Food Starch & Potato Dextrin: These act as thickeners and stabilizers in the seasoning mixture.
Carrageenan: Derived from seaweed, this helps with moisture retention.
Sugar & Dextrose: Provide a hint of sweetness that enhances the savory flavors.
Spice Extractives: The exact blend remains a trade secret, but these provide the characteristic flavor we associate with Costco’s rotisserie chicken.
The Cooking Process: Key to the Flavor
Beyond ingredients, Costco’s cooking method plays a huge role in creating their signature taste. They use specialized high-efficiency ovens that cook the chickens relatively quickly while ensuring even heat distribution.
The chickens rotate on spits, which allows for:
- Uniform cooking
- Self-basting (the chicken’s own juices continuously coat the meat)
- A crispy, golden-brown exterior
This cooking process takes just over an hour from raw chicken to finished product, resulting in the juicy, tender meat Costco is known for.
The Recent Controversy: Chemical Taste?
In early 2023, discussions erupted online about a potential change in the taste of Costco’s rotisserie chickens. A Reddit thread with over 200 comments featured customers describing their recent purchases as having a “weird chemical taste,” a “distinct chlorine-like taste,” or tasting “like the plastic they’re packaged in.”
So what gives? There are several theories:
-
Regional Supplier Differences: Different Costco locations might source chickens from different suppliers, leading to taste variations.
-
Packaging Changes: Some users speculated that changes in packaging materials or processes might affect the flavor.
-
Individual Sensitivity to Phosphates: As mentioned earlier, some people may be more sensitive to the taste of sodium phosphate than others.
-
Preparation Variations: Different Costco locations might have slight variations in their cooking techniques or seasoning application.
It’s worth noting that not everyone is experiencing this issue. When Today.com investigated in March 2023, their writer described the taste simply as “chicken.”
Nutritional Information
For those counting calories or watching their nutrition, here’s what you can expect from a typical serving (85g) of Costco rotisserie chicken:
- Calories: 140-170 (depending on the cut)
- Fat: 4-7g

Why Costco’s Rotisserie Chicken Remains So Popular
Despite the recent taste controversy, there are several reasons why Costco’s rotisserie chicken continues to fly off shelves:
1. Unbeatable Value
At $4.99, you get a fully-cooked, seasoned, ready-to-eat chicken that can feed a family or provide multiple meals for an individual. In today’s economy, that’s hard to beat!
2. Convenience Factor
No preparation, no waiting, no mess. Just grab and go! For busy families and individuals, this convenience is priceless.
3. Versatility
I personally love how versatile these chickens are. You can:
- Serve it as is with sides
- Shred it for tacos, salads, or sandwiches
- Use it in soups, casseroles, or pasta dishes
- Make chicken stock from the bones
One customer mentioned using the meat for a BBQ chicken dish by combining it with barbecue sauce, crushed pineapple, minced dried onions, and smoked sea salt in a crockpot – sounds delicious!
Should You Be Concerned?
For most people, Costco’s rotisserie chicken is perfectly safe and nutritious. However, there are a few considerations:
- Sodium content: The chickens are relatively high in sodium, which might be a concern for those monitoring salt intake.
- Additives: While all ingredients are FDA-approved, some people prefer to avoid additives like sodium phosphate and carrageenan.
- Taste sensitivity: If you’re among those who detect a chemical taste, you might want to try chickens from different Costco locations or opt for alternatives.
The Bottom Line
Costco’s rotisserie chicken remains one of the best values in grocery shopping today. With simple ingredients, an effective cooking process, and that unbeatable $4.99 price tag, it’s no wonder they sold 117 million chickens in 2022 alone!
While some customers have reported taste issues, many continue to enjoy these birds without complaint. The ingredients are straightforward and the nutrition profile is solid, especially considering the convenience and price.

P.S. If you’re concerned about the taste but still want the convenience, try removing the skin before eating or adding your own seasonings to mask any potential off-flavors. Some customers have reported that reheating the chicken with additional spices helps significantly!
Rotisserie chicken sales have almost doubled in the last decade.
The popularity of Costco’s famous bird only continues to grow. During fiscal year 2010, Costco sold 51 million rotisserie chickens. Since 2020, the big-box retailer has sold more than 100 million rotisserie chickens yearly. In January, Costco reported that it sold 117 million in 2022. This is around 11 million more chickens than in 2021—an increase of about 10%.
The chicken is reported to be a major loss leader for Costco.
Costco’s rotisserie chicken is reportedly a “loss leader”—a product sold below its actual market value to attract customers to the store, where it’s hoped they will purchase other profitable items.
In 2015, Galanti said, “When others were raising their chicken prices from $4.99 to $5.99, we were willing to eat, if you will, $30 to $40 million a year in gross margin by keeping it at $4.99.” However, in 2019, Jeff Lyons, Costco’s senior vice president of fresh foods, declined to tell CNN whether the retailer still loses money on its rotisserie chickens.

Why does Costco put carrageenan in rotisserie chicken?
So, this polysaccharide is added to rotisseries as an additive. As the chicken rotates over heat to slow cook, it can lose moisture, become hard and shrink. To make it bulkier, juicier, and more tender, the hydrogel carrageenan is smeared on the chicken.
