Smashburger is a popular restaurant that offers burgers, sides, and milkshakes among other menu items. If you enjoy grabbing a burger for dinner with your family or friends, you may have found yourself at a Smashburger – or at least considering visiting one.

If you’re following a gluten-free diet, you know that it’s not always easy to find restaurants that offer safe options for folks like us. That’s why I’ve decided to dig into the details on how Smashburger says they handle gluten and other allergens, as well as what their menu options are that don’t contain gluten ingredients.

By the time you finish reading this post, you’ll have a good understanding of how Smashburger handles gluten in their kitchens, what you need to know about cross contamination, and what menu items from Smashburger may (or may not) be options you can consider ordering on a gluten-free diet.

Let’s talk Smashburger!

What is gluten?

Gluten is a protein found in most wheat products, and acts as the “glue” that helps to hold wheat, barley, kamut, spelt, farro, durum, bulgur, rye, and semolina together to maintain their shape. 

Gluten is naturally occurring, and therefore is impossible to strip away from the grain. If a grain naturally has gluten in it, there’s no way to make that food gluten-free.

Where can you find gluten in food?

Gluten can be found in the form of wheat and grain products, like bread or flour in the more obvious places.

You can also find gluten as a binding ingredient, an ingredient added for texture like to make a food more crispy, or as a thickening agent.

Where can you find gluten in restaurants?

Depending on the restaurant you’re visiting, you may find gluten in a variety of places. 

At fast food restaurants, there will be gluten in hamburger buns, the breading of crispy chicken sandwiches or chicken nuggets, some French fries, salad dressings, croutons on salad, and chili or soup options.

At other restaurants, you’ll find gluten in flour in sauces, in pizza or other pastry dough, pasta, and as a thickener in some soups. 

Where gluten is found in the menu items will vary from restaurant to restaurant. That’s why it’s always a good idea to review menus from home, and see if you can find any allergen information before you get to the restaurant itself.

Being able to review nutritional information and allergen statements before visiting a fast food restaurant can be the difference between ordering something that you think is safe for your gluten-free diet and getting sick.

Being knowledgeable about what specific menu items you’ll be able to eat without any worries of later reactions is crucial to sticking with your gluten-free diet.

Smashburger allergen statement

Smashburger has an interactive allergen and nutritional menus area on their website. This is the information they provide regarding how they handle gluten and other allergens in their kitchens and what to expect when you visit this restaurant:

“We strive to ensure that every guest has a great dining experience, and that includes those with special dietary needs and medical requirements. For this reason, we have prepared the following menu options based on information obtained from our food suppliers. 

Every effort is made to keep this information current and accurate. However, ingredient changes may occur due to substitutions, preparation variation, and regional availability of products.

We encourage you to use these menu options as a tool to help you make your dining choices. These options are not intended to supersede professional medical advice that you have received. 

We will update these online menus as our menu selections, ingredients, and/or preparation techniques change. Please visit our website upon each visit for the most current allergen/sensitivity and nutritional information available.

Please be advised that food prepared in our kitchens may contain these ingredients: milk, eggs, wheat, soybean, peanuts, tree nuts, fish and shellfish. 

While every effort is made to minimize the risk of cross contamination, we cannot guarantee that our food products are free of any of these allergens or are gluten-free, vegetarian or vegan.”

What you need to know about the gluten-free options at Smashburger

With the Interactive Allergen & Nutritional Menus on the Smashburger website, you can choose which food allergies and restrictions you have to narrow the menu down to items that work for your diet. You can choose from milk, eggs, gluten, wheat, soy, peanuts, tree nuts, fish, and shellfish.

The menu comes up with “OK to eat with modifications” for menu items that you may consider ordering. With each of the menu items, you can click in for more details and it will show you with a red font and a line through it telling you what modifications or omissions you need to make to your order to make it free of gluten ingredients.

Keep in mind that everything listed in this post are not truly gluten-free options. They simply do not contain gluten ingredients. There is still a chance for cross contamination in the kitchens and prep areas due to shared equipment, utensils, and prep surfaces.

If you decide this restaurant is worth visiting, even with the knowledge that gluten cross contact is probable, keep in mind that all burgers will need to be ordered with a gluten-free bun or lettuce wrap.

All chicken and turkey menu items should be ordered without any haystack onions or smoked brisket. Four of their wings options don’t have gluten ingredients, as well as all their shakes and many of their side dishes.

What to know about cross contamination at restaurants

Most fast food and carryout restaurants are not considered gluten-free establishments so it’s useful to keep this in mind when making decisions about where to go and what to order.

It’s important to know that even if a fast food restaurant claims that their menu items do not contain gluten, that the possibility and probability of gluten in their products is going to be high if there is even one menu item with gluten available. 

Depending on your level of sensitivity to gluten, this can be make or break information for you.

If you are Celiac and are allergic to trace amounts of gluten, you’ll likely want to avoid most fast food restaurants that offer any bread products or French fries that are cooked in a shared fryer with other gluten-containing ingredients.

If you are not sensitive to gluten at the trace level and have adverse reactions to gluten due to a food intolerance, you may decide that these trace amounts of gluten from cross contamination are worth risking for a quick, easy, and convenient food option.

Being aware of how you have reacted to gluten in your diet in the past and how much gluten it takes for your body to react is useful knowledge when it comes to situations like these.

Use your best judgment about what you know about your body, how you react to gluten, and what the risks are for you specifically.
