Ultimate Steak Sub: Allergens at a Glance
The honest verdict
Ultimate Steak Sub
An Ultimate Steak Sub is a warm sandwich featuring sliced steak, melted cheese, and often grilled onions and peppers on a sub roll. The allergen profile is anchored by wheat from the roll, milk from the cheese, and soy from the steak's seasoning and cooking oil. Egg and sesame may appear in the roll. The steak itself is typically beef, but the seasoning blend may contain soy or wheat-derived ingredients. Cross-contact from shared grills and prep surfaces is a real concern. This is a hot sub — different from a cold-cut sub (see cold-cut-combo) or a chicken sandwich (see crispy-chicken-sandwich-6048f). Always confirm the specific ingredients and preparation methods with your restaurant before ordering.

Key facts
The sub roll is the primary source of wheat in the Ultimate Steak Sub. Gluten-free alternatives are not standard.
FDA — Food Allergen Labeling and Consumer Protection Act (FALCPA)
Melted cheese is a standard component, making milk a primary allergen. Ordering without cheese removes this source.
Soybean oil and soy-based seasonings are common in steak preparation, making soy a multi-source allergen in this sandwich.
Every major allergen, one clear grid
Each of the nine major allergens marked for Ultimate Steak Sub — Contains, May contain (cross-contact or varies), or Free. Anything we couldn't confirm defaults to "may contain," because a shared kitchen can't be ruled out without the restaurant's official menu.
- MilkContains
Melted cheese (typically provolone, mozzarella, or American) is a standard component of the Ultimate Steak Sub. The steak itself may also be seasoned with butter or dairy-based flavorings. Ask about cheese type and whether the steak is cooked with butter.
- EggMay contain
Egg is not a primary ingredient in the steak or cheese, but the sub roll may contain egg (enriched doughs often do). Some steak seasoning blends or sauces (like aioli) may also contain egg. Confirm the roll ingredients and any sauces with the restaurant.
- Wheat / GlutenContains
The sub roll is wheat-based. This is the primary source of wheat in the sandwich. Some steak seasonings or marinades may also contain wheat-derived ingredients (soy sauce, malt vinegar). There is no standard gluten-free sub roll at most chains.
- SoyContains
Soybean oil is commonly used to cook the steak and vegetables. The steak seasoning may also contain soy sauce or hydrolyzed soy protein. The sub roll may contain soy lecithin or soy flour. Soy is a multi-source allergen in this sandwich.
- PeanutFree
Peanut is not a standard ingredient in steak subs. Peanut oil is not typical for cooking steak at fast-food chains. Cross-contact is very unlikely.
- Tree NutFree
Tree nuts are not a standard ingredient in steak, cheese, or sub rolls. Not a concern for this menu item by ingredient.
- FishFree
Fish is not an ingredient in the steak, cheese, or roll. Cross-contact from shared grills is possible if fish items are cooked on the same surface.
- ShellfishFree
Shellfish is not an ingredient in this sandwich. Cross-contact is very unlikely in a typical fast-food kitchen.
- SesameMay contain
Sesame seeds are sometimes sprinkled on sub rolls for texture and flavor. Some steak sauces (teriyaki-style) may also contain sesame oil. Confirm the roll type and any sauces with the restaurant.
“May contain” means cross-contact is possible or the answer varies by location — not that the allergen is a listed ingredient. For a severe allergy, treat “may contain” the same as “contains” until the restaurant confirms otherwise.
Small changes that remove an allergen
Simple modifications that can take an allergen off your ultimate steak sub. Always name your allergy when you order and ask staff to confirm — a modification only helps if the kitchen prepares it separately.
Order without cheese
Request a lettuce wrap or bowl instead of the sub roll
Ask for the steak to be cooked without seasoning or sauce
Request a gluten-free bun or wrap if available
A modification lowers exposure but doesn't erase cross-contact from shared fryers, grills, or prep surfaces. For a severe allergy, confirm the prep with a manager before you eat.

Cross-contact & severe allergies
A “free of” mark on the grid above means the allergen isn't an ingredient — it doesn't mean the item was made in an allergen-free kitchen. Two things matter most:
Shared fryers & equipment
Shared grills, prep surfaces, and utensils in fast-food kitchens mean the steak, vegetables, and roll can pick up trace allergens from other menu items. The same grill may cook chicken, fish, or other sandwiches. The sub roll may be stored near or handled after other bread products. Cross-contact risk is present for wheat, milk, soy, and fish. Ask the restaurant about their kitchen practices.
If your allergy is severe
For anaphylactic allergy to wheat, milk, soy, or sesame, confirm the specific ingredients and preparation methods with the restaurant before ordering. The Ultimate Steak Sub is not guaranteed safe for any of these allergens without direct restaurant confirmation. Carry your epinephrine auto-injector. If you cannot verify preparation details, consider a simpler item like a grilled chicken salad with no cheese and a known-safe dressing.
This guidance is general and can't account for how any single location prepares your food. The restaurant's staff and official allergen menu are the final word — when in doubt, ask, or choose something else.
❓Frequently Asked Questions
The Ultimate Steak Sub is a hot sandwich typically made with sliced steak, melted cheese (provolone or mozzarella), and grilled onions and peppers on a toasted sub roll. Some versions include sauces like mayo, mustard, or a signature steak sauce. It is a steak-and-cheese sub — different from a cold-cut sub (see cold-cut-combo) or a chicken sandwich (see crispy-chicken-sandwich-6048f).
Yes, milk is a primary allergen in this sandwich due to the melted cheese. The steak itself may also be cooked with butter or a dairy-based seasoning. To remove dairy, order without cheese and ask if the steak is cooked with butter. If it is, request a plain grilled steak option.
No, not in its standard form. The sub roll is wheat-based. The steak seasoning may also contain wheat-derived ingredients like soy sauce or malt vinegar. To make it gluten-free, request a lettuce wrap or a gluten-free bun (if available) and ask for the steak to be cooked without seasoning. Confirm that the grill is not shared with breaded items.
Yes, soy is a common ingredient in steak seasoning blends and in the cooking oil used to prepare the steak. Soybean oil is the standard cooking oil at most fast-food chains. The sub roll may also contain soy lecithin. Soy is a multi-source allergen in this sandwich. Ask the restaurant if they can prepare the steak without seasoning or with a soy-free oil.
Yes, sesame may be present on the sub roll (sesame seeds) or in sauces (teriyaki-style). Egg may be in the roll or in sauces like mayo or aioli. Cross-contact from shared grills can introduce fish or other allergens. Always check the specific roll type, sauce ingredients, and cooking practices at your location.
