In-n-Out Burger Keeps it Simple for Special Diet Diners


On road trips, that big yellow arrow is a welcome site around lunch time. Out west, In-n-Out Burger has become the spot for grabbing a bite while running errands or for pit stops on long highway stretches. And it isn’t because they have a wildly creative menu. In fact, they pretty much make one thing, hamburgers with fries. But they do it quite well.

Dairy-Free Menu Guide for In-n-Out Burger with Allergen Notes

Dairy-Free Menu Guide for In-n-Out Burger with Allergen Notes

This is the easiest dairy-free menu guide I’ve ever made, since the In-n-Out food menu has less than five items on it. Yes, their buns are dairy-free, and their sauces are dairy-free. Just avoid the cheese and milkshakes (sorry!) and you’re good to go. But to make it look like I worked a little, I’ve added some additional menu and food notes.

Additional Allergen Notes: In-n-Out Burger does not use peanuts, treenuts, sesame, shellfish, or fish in their restaurants. Egg-free guests should skip the spread (order Ketchup & Mustard instead), and Soy-Free guests should skip the spread and order Protein-Style. The buns contain soy.


  • Hamburger
  • Double Double Burger (no cheese)

Not-So-Secret Menu Options:

  • Protein Style (Gluten-Free): Place this order if you want your burger in a lettuce wrap instead of a bun. Their bun is dairy-free (but does contain wheat) and is not buttered.
  • Animal Style: Order this if you want your patty cooked with mustard, and your burger topped with extra spread, pickles, and grilled onions (instead of raw).
  • Ketchup & Mustard Swap: If you aren’t a fan of their spread (it’s basically Thousand Island and is dairy-free), you can order ketchup and mustard instead.


  • French Fries (vegan)

Fryer Note: The French Fries are made with fresh sliced potatoes, cooked in 100% sunflower oil, and they are the only fried food at In-n-Out Burger.

Love the simple menu

I’m a fan of real potato fries, so I love their French fries. And the fact that they’re made in a dedicated fryer. I’ve never had an issue with their burgers, either, and love how easy it is to order – no cheese. Several locations will clean the grill, too, to help prevent cross-contamination.

I have an anaphylactic allergy to dairy. I always order this combo and never have a problem. Today I had a severe reaction. Bun, hamburger, sauce, tomato, lettuce, onion, fries with packet ketchup. The only thing I can think of is cross contamination. Love In n Out but not so sure there will be a next time. Too scary.
