Allergen Information


About Our Allergen Information

It is important to note that many allergens are present in our restaurants, including milk, egg, fish, peanut, tree nut, shellfish, soy, and wheat. 

At Portillo's, we empathize with the challenges facing the families of people who have food allergies and who need to manage dietary sensitivities in their lives. When placing your order, please alert our order taker and manager to your food allergies or dietary restrictions.

Because we do not have separate kitchen equipment dedicated for the preparation of allergen-based food requests, foods may come into contact with one another during preparation, which is not reflected on the nutritional chart. Please consult your healthcare provider to determine the types of precautions you should take before enjoying any of our menu items.

Special Notes for Specific Food Allergies:

Fish and Seafood

Our fried fish and fried chicken products share a fryer. Because of this, we cannot guarantee that your fried chicken sandwich has not come into contact with fish. Please take this into consideration when ordering fried chicken if you have a seafood allergy.


  • Our French fries are gluten-free and cooked in their own designated fryer. However, the equipment used to filter the oil in the French fry fryer is shared with the fryers responsible for frying items that do contain gluten (i.e. breaded chicken, breaded fish, and onion rings). Please take this into consideration when ordering French fries if you are sensitive to gluten.
  • Barnelli's only: The grilled chicken product used for select sandwiches and salads at Barnelli's contains gluten. This pertains ONLY to the hot grilled chicken product used on the Hot Grilled Chicken Caesar Salad and Grilled Chicken Nudie (served without a bun either on the side or as a sub to cold chicken on another salad). Note that cold chicken (served on the Chopped Salad, Chicken Pecan Salad, Poppyseed Fruit with Chicken Salad and Southwest BBQ Salad) served at Portillo's and Barnelli's AND the hot grilled chicken from Portillo's does NOT contain gluten.
