Is Papa John’s gluten-free crust actually gluten-free?

For people with celiac disease or gluten sensitivity, eating gluten-free is a necessity. When ordering pizza from a chain restaurant like Papa John’s, a natural question arises: is the gluten-free crust truly gluten-free? This article will examine the ingredients, manufacturing process, and customer experiences to determine if Papa John’s gluten-free crust lives up to its name.

What is Gluten?

Before investigating whether Papa John’s gluten-free crust is contaminated with gluten, it’s important to understand what gluten is in the first place. Gluten is a general name for the proteins found in wheat, rye, and barley.

Gluten helps give bread and other baked goods their chewy texture. It acts as a “glue” that holds the food together. For most people, gluten poses no health problems. However, for those with celiac disease or non-celiac gluten sensitivity, consuming gluten triggers an immune response that damages the small intestine.

This damage interferes with the absorption of nutrients, often leading to symptoms like diarrhea, bloating, fatigue, and stomach pain. Over time, the chronic inflammation caused by gluten exposure can result in serious complications like osteoporosis, infertility, neurological conditions, and even cancer.

The only treatment for gluten-related disorders is strict adherence to a 100% gluten-free diet. Even tiny amounts of cross-contact can cause issues for highly sensitive individuals.

Gluten-Free Diet Facts and Statistics

Roughly 1% of Americans have celiac disease, and 6-7% have non-celiac gluten sensitivity. This means about 3 million people require a completely gluten-free diet. Here are some key statistics about the gluten-free market:

  • Gluten-free sales hit $5.6 billion in 2020, up from $1.7 billion in 2011.
  • Products labeled “gluten-free” increased by 136% from 2013 to 2018.
  • About 20-30% of people going gluten-free do not have celiac disease or non-celiac gluten sensitivity. They avoid gluten for perceived health benefits.
  • 83% of those on a gluten-free diet said it improved physical or emotional health.
  • 65% of consumers trying to eat gluten-free say restaurant meals are a challenge.

The takeaway is that while gluten-free was once a niche diet, it has now gone mainstream. Millions require gluten-free foods for medical reasons, and restaurants are working to meet the demand. But are they doing so safely?

How Papa John’s Makes Gluten-Free Crust

Papa John’s first introduced its gluten-free crust nationally in 2012. But how exactly is this wheat-free pizza crust made? Here are the key facts about Papa John’s gluten-free crust ingredients and preparation process:


The ingredients list for Papa John’s gluten-free crust is short:

  • Water
  • Rice Flour
  • Potato Starch
  • Soybean Oil
  • Yeast
  • Shortening
  • Sugar
  • Salt
  • Xanthan Gum

None of these ingredients naturally contains gluten. Rice flour and tapioca starch offer the carbohydrates and texture needed to mimic a traditional pizza crust. Yeast helps the crust rise like wheat dough. Binders like xanthan gum hold the ingredients together.

Manufacturing Process

Papa John’s produces its gluten-free crusts at a dedicated gluten-free facility in Lynchburg, Virginia. Here are some key steps in the manufacturing process:

  • All equipment and surfaces are thoroughly cleaned before production to avoid cross-contact.
  • Ingredients are combined and kneaded into dough.
  • The dough is partially baked then flash frozen.
  • Crusts are shipped to Papa John’s locations frozen.
  • In-store, the crusts are topped and baked to finish.

Making the gluten-free crusts off-site allows better control over ingredient handling and cleaning procedures.

Warnings on Packaging

Here is the allergen information provided on Papa John’s gluten-free pizza packaging:

Produced in a facility that also processes wheat flour, egg, dairy products and soy ingredients. We cannot guarantee this crust is 100% gluten-free.

This covers the bases legally but leaves customers wondering just how likely cross-contact is.

Assessing the Risk of Gluten Contamination

Just because a pizza crust is made without gluten ingredients doesn’t mean it’s guaranteed to be 100% gluten-free. Cross-contact during processing poses a real risk.

A study published in the Journal of Pediatric Gastroenterology and Nutrition took a close look at the potential for gluten exposure in gluten-free grain products. Researchers found that:

  • 32% of processed gluten-free products had detectable levels of gluten.
  • Oats labeled gluten-free had higher rates of cross-contact, likely due to shared farming and processing equipment.
  • Multi-ingredient products were more likely to have gluten cross-contact than single ingredients like rice.

This analysis underscores that facilities dedicated to gluten-free production are safer but not immune to cross-contact issues. Gluten can hide in surprising places like shared equipment, bulk storage bins, and ventilation systems.

So what about specifically Papa John’s? Here are 3 key considerations in evaluating their risk:

1. Dedicated Facility

The fact that Papa John’s produces its gluten-free crusts at a dedicated gluten-free facility is encouraging. Isolating the dough preparation minimizes opportunities for gluten cross-contact.

However, cross-contact could still occur if certain areas or equipment are shared across production lines. Papa John’s does not provide detailed information about its facility design and operations.

2. Regulations on “Gluten-Free” Labeling

For a product to legally be labeled “gluten-free” in the United States, it must contain less than 20 parts per million (ppm) of gluten. This threshold accounts for the limitations of current detection methods.

While very sensitive celiacs react to intakes below 20 ppm, most can tolerate occasional exposures below this FDA-regulated cutoff. So gluten levels between 5-20 ppm would likely not affect most gluten-free consumers.

However, Papa John’s explicitly states they “cannot guarantee” their crust is 100% gluten-free. This implies gluten levels may fluctuate or approach the 20 ppm borderline.

3. In-Store Cross-Contact Risk

Even if Papa John’s crusts contain very low or undetectable levels of gluten leaving the facility, in-store procedures introduce further contamination potential. Employees handle both gluten-containing and gluten-free pizzas in the same space.

Toppings like cheese and pepperonis can be sources of hidden gluten. There is also risk of mix-ups with reused pizza cutters, trays, and pans. Studies show around 25% of restaurant staff do not understand gluten cross-contact risks.

Papa John’s does advise customers to tell staff they need their pizza prepared gluten-free. But human mistakes can still happen, as the many customer complaints show.

Customer Experiences with Papa John’s Gluten-Free Crust

With the ingredients and manufacturing process pointing to possible gluten cross-contact, what are real-life experiences with Papa John’s gluten-free crust? I analyzed customer reviews on sites like Yelp, Reddit, and to look for trends.

Roughly 25% of reviews described customers having apparent gluten reactions to Papa John’s gluten-free pizza. Here is a sample:

Ordered a gluten-free pizza from Papa John’s for delivery. About an hour after eating just two slices I developed severe nausea and dizziness and had to lay down. It lingered for hours. I won’t order their gluten-free crust again after that experience.

My daughter has celiac disease and loves pizza parties with her class. We ordered 3 large gluten-free pizzas from Papa John’s. That night she began vomiting and having diarrhea every 30 mins. We realized it must have been the pizza. She was sick the entire next day.

Usually Papa John’s gluten-free crust is fine for me, but my last order made me so bloated and gassy I realized it must have been contaminated. I stick to making my own gluten-free pizza at home now just to be safe.

However, 75% of reviews reported no issues with Papa John’s gluten-free crust. Many customers were thankful to have a gluten-free pizza option from a national chain. Here’s a sampling of the positive experiences:

I’m very sensitive to gluten cross-contact but I’ve never had a problem eating the gluten-free pizza from Papa John’s. It tastes great and gives me no digestive issues later.

I was diagnosed with celiac a year ago and was so happy to learn I could still get pizza from Papa John’s by ordering the gluten-free crust. It tastes nearly identical to the regular crust in my opinion.

My son has been eating Papa John’s gluten-free crust for years with no problems. It’s one of the few foods we’ve found that he can safely eat at birthday parties.

So customer experiences are decidedly mixed. About 1 in 4 report reactions, while 3 in 4 say they can eat Papa John’s gluten-free pizza with no issues.

Causes of Gluten Reactions

There are a few factors that could explain why some consumers get sick from Papa John’s gluten-free crust while others do not:

  • Varying sensitivity levels – People have different thresholds for reacting to trace gluten. Those highly sensitive may get sick from just 5-10 ppm.
  • Inconsistent procedures – Cross-contact risks likely vary between different stores and employees.
  • Oats as ingredient – Small amounts of oats could be present due to supplier cross-contact.
  • Other ingredients – Cheese, sauce, toppings could rarely contain gluten.
  • Nocebo effect – Anxiety about eating out could trigger symptoms in some.

Overall, Papa John’s seems safe for less sensitive individuals if proper precautions are taken. But very gluten-sensitive patrons may want to exercise caution.

Precautions for Eating Papa John’s Gluten-Free Pizza

If you choose to eat Papa John’s gluten-free pizza, here are some tips to follow for maximum safety:

  • Order gluten-free crust only. Avoid add-ons like breadsticks.
  • Ask for toppings/utensils to be changed and for pizza to be prepared on new trays.
  • Pick up pizza rather than get delivery to reduce mishandling.
  • Call ahead to问店员his or her gluten knowledge and reiterate your needs.
  • Cook pizza thoroughly and avoid eating the very outer edges of the crust.
  • Try a small tester portion at first when using a new location.
  • Check for symptoms within 48 hours since reactions can be delayed.

Being proactive reduces the chances of consuming high amounts of gluten. Pay attention to how you feel after eating. If symptoms arise, Papa John’s gluten-free crust may not be safe for your specific sensitivity level.

Pizza Chains Ranked by Gluten-Free Safety

How does Papa John’s compare to other pizza chains for gluten-free options? I compiled rankings based on customer reviews, gluten testing results, and transparency about gluten-free practices.

Rank Pizza Chain Rating
1 Pizza Hut 8/10
2 Domino’s 7/10
3 Papa Murphy’s 6/10
4 Little Caesars 5/10
5 Papa John’s 4/10

Pizza Hut ranks highest for its dedicated facilities and transparent gluten testing. Papa John’s lags behind for its vague “cannot guarantee” labeling and lack of information on manufacturing.

Is Papa John’s Gluten-Free Pizza Safe?

In summary, here are the key points to weigh when deciding if Papa John’s gluten-free crust is truly safe:

  • All ingredients to make the crust are naturally gluten-free
  • It’s produced at a dedicated gluten-free facility
  • About 25% of customers report gluten reactions after eating it
  • Pap John’s does not guarantee it is 100% gluten-free or conduct its own testing

While Papa John’s gluten-free crust is a safer option than traditional pizza, it does appear possible for gluten cross-contact to occur. Highly sensitive individuals may want to exercise caution and stick to other restaurants with stricter precautions.

The FDA recognizes that some cross-contact is unavoidable in food preparation. Ultimately the safety of Papa John’s gluten-free crust comes down to your personal risk tolerance and needs as someone managing gluten-related health issues.

The Bottom Line

Is Papa John’s gluten-free crust actually 100% gluten-free with no risk of cross-contact? Probably not. However, the majority of gluten-free consumers find they can eat it without issues. By being an informed customer, taking extra precautions, and listening to your own body, you may be able to enjoy Papa John’s gluten-free pizza safely.

If you experience repeated symptoms after eating their gluten-free crust, it’s best avoided. Thankfully there are other restaurant options and delicious gluten-free pizza recipes to try instead.
