Eating at Del Taco with celiac disease, IBS or food allergies

Del Taco publishes allergen and ingredient details on each menu item page, so you can see what goes into a taco before you order. As of October 2026, each item lists milk, eggs, fish, shellfish, tree nuts, peanuts, wheat, sesame, soybeans, gluten and MSG. But on the pages we checked, every taco, burrito and quesadilla was marked for gluten, and Del Taco doesn’t describe any item as gluten-free or allergen-free.

Del Taco’s pages also say that its restaurants "use the same frying oil to prepare menu items that could have meat in them", and that it "cannot confirm whether any of our ingredients did not come into contact with meat products". That note is written for vegetarians, but it tells you the fryer is shared.

This guide summarizes what Del Taco’s own pages say about gluten, the major allergens and common FODMAP sources, and what to ask. It doesn’t point to choices that are free from risk.

Del Taco’s menu pages show why so many items are marked for gluten. As of October 2026:

• Flour tortillas for burritos, quesadillas and soft tacos list enriched wheat flour.
• Beans have two possible ingredient statements "depending upon regional suppliers". One includes dried soy sauce (soybeans, wheat, salt); the other lists onions and garlic. Items with beans, including the CrunchTada Tostada on a corn shell, are marked for wheat, soy and gluten.
• Seasoned beef lists wheat protein, soy and oats. The Del Taco crunchy taco has a corn shell, but it is marked for wheat and gluten because of the beef.
• Grilled marinated chicken lists soy sauce made with wheat.
• Mini churros list wheat starch, plus milk, egg and soy. Del Taco labels them as fried.

The Celiac Disease Foundation lists soy sauce among gluten sources and notes that oats are easily contaminated unless labeled gluten-free. Our guide to whether soy sauce is gluten-free explains why it turns up in beans and marinades.

Some items had no wheat or gluten marked, such as the crinkle-cut fries and hash brown sticks. Those pages also carry Del Taco’s shared frying oil note. Del Taco doesn’t say whether churros, battered fish or breaded chicken share that oil, and the Celiac Disease Foundation notes that fried foods cooked in oil shared with breaded products are a cross-contact risk. Ask at your location before ordering anything fried.

The NIDDK advises telling your server you have celiac disease and asking about ingredients and preparation. Our guides to eating out with celiac disease and gluten-free vs celiac-safe go further.

These examples come from Del Taco’s menu item pages for its tacos, burritos and vegetarian and vegan items. They describe what Del Taco lists, not recommendations, and they can change.

Del Taco’s September 2026 allergen list marks these items the same way, with one exception: it marks the egg and cheese breakfast burrito for milk, egg, wheat and gluten, but not soy. Where Del Taco’s own information doesn’t line up, ask in store:

• Carne Asada Steak Street Taco: it is marked for gluten but not wheat, and its listed ingredients (corn tortilla, carne asada, green sauce, onions, cilantro) don’t name a wheat or gluten ingredient.
• Grilled Chicken Street Taco: the description says it comes in a corn tortilla, but the ingredient statement lists a tortilla made with wheat flour, and the item is marked for wheat.
• Funnel cake fries and mini sweet cream churros: the allergen list marks both for wheat but not for gluten. Wheat contains gluten, so treat them as containing gluten.
• Jalapeños: the allergen list marks them as vegan and also marks them for egg.

Other entries in that allergen list, as of its September 2026 edition:

• Corn tortilla, taco shells, tortilla chips and tortilla strips are marked for no allergens. Items built on them can still be marked for wheat or gluten because of the fillings.
• Pinto beans are marked for wheat, soy and gluten, and seasoned beef for wheat, soy and gluten.
• Carnitas are marked for no allergens, but the Carnitas Street Taco is marked for milk and gluten.
• Chips and fresh house-made guac is marked vegan with no allergens; chips and queso is marked for milk.
• Hamburger buns are marked for wheat, soy, sesame and gluten. Del Taco also notes "a possibility for cross contact with sesame seeds" in its kitchens and hamburger prep areas.

In the September 2026 allergen list, no item was marked for peanuts, tree nuts or shellfish, only the fish taco and battered fish were marked for fish, and sesame was marked only on the burgers and buns. That reflects ingredients only. Our guide to food allergies and the major allergens explains why cross-contact still matters.

Based on Del Taco’s ingredient statements as of October 2026:

• Garlic and onion: red sauce lists onions and garlic powder; green sauce lists garlic powder; salsa casera lists garlic; seasoned beef lists onions and garlic powder; grilled chicken lists garlic and onion powder; carne asada lists onion and garlic powder.
• Guacamole: avocado, tomato, onion, cilantro, lime juice and a seasoning with onion and shallot.
• Cilantro lime rice: a sauce with green onion and garlic purée.
• Beans: pinto beans, plus onions and garlic in one regional version.
• Wheat: flour tortillas, seasoned beef and the chicken marinade.
• Lactose: cheddar and sour cream (cultured cream).

Monash University lists garlic, onion, most legumes and wheat-based breads among higher-FODMAP foods, and lettuce, potato and hard cheeses among lower-FODMAP ones. Most Del Taco sauces carry some garlic or onion, so asking for sauce on the side and choosing simpler fillings are common starting points. Portion matters with beans and avocado: our guides to beans, lentils and IBS, whether avocado is low FODMAP and Mexican restaurants with IBS, celiac disease and allergies explain more.

1. Open each item’s page before you go and read both the allergen list and the ingredient statement, since they can tell you different things.
2. Tell the team at the start about any allergy or celiac disease, including at the drive-thru speaker.
3. Ask which bean recipe your location uses if wheat, soy, garlic or onion matters to you.
4. Ask what shares the fryer before ordering fries or hash brown sticks.
5. Ask for sauces on the side and for a glove change if you have an allergy.
6. If you’re unsure, skip it. It’s fine to choose something simpler or eat elsewhere.
