Is Culver’s Mushroom & Swiss ButterBurger Gluten-Free?
Not as served, because the standard burger uses a wheat Kaiser bun. But Culver’s offers two ways to adjust it: a gluten free bun or no bun at all.
Can You Order It Without a Bun?
Yes. Choose “No Bun” and you save $0.30 and 220 calories. Your culvers mushroom swiss burger no bun order keeps the beef, mushrooms and Swiss cheese.
You can also pick the Gluten Free Hamburger Bun for $1.20 extra. It comes packaged separately.
Allergen and Cross-Contact Information
Culver’s allergen guide checks for gluten, milk, eggs, fish, shellfish, tree nuts, peanuts, wheat, soy and sesame. By ingredients, the bun contains wheat and the Swiss cheese and butter contain milk.
If you have celiac disease or a serious allergy, check Culver’s official Nutrition & Allergen Guide and tell the restaurant team before ordering. Cross-contact can happen in any busy kitchen, even when you choose a gluten free bun.
Is Culver’s Mushroom & Swiss ButterBurger Healthy?
It is a rich, indulgent fast food burger, not a light meal. The Double has 780 calories, 20 g of saturated fat (100% DV) and 47 g of protein. It fits better as an occasional treat than an everyday meal, and the Single is the lighter pick.
Is It Suitable for a Low-Carb Diet?
Not in its standard form, because the bun adds 220 of the Double’s 780 calories. Ordering it with no bun cuts those calories and makes it more low-carb friendly.
If you follow keto, the no bun order is the closest fit, since the patty, mushrooms and Swiss cheese are the main parts left. Culver’s does not list carbs for the no bun version on the menu page, so call it lower-carb, not strictly keto, and check the Nutrition & Allergen Guide.
