Low Carb In-N-Out Burger Options for Keto Diets

Family-owned for 70 years, California-based In-N-Out has slowly been expanding to other states. Much to the joy of burger aficionados who don’t live in the Golden State, some of In-N-Out’s 300 restaurants are now located in Texas, Utah, Arizona and Oregon.

The beloved burger joint got its start back in 1948 Harry Snyder opened California’s first drive-thru restaurant in Baldwin Park. The space was barely 10 feet square! He would get up early every morning to scour the markets for fresh ingredients that he would later prepare by hand. While Harry did the cooking, his wife handled the accounting in their nearby home. Harry worked on another pet project at home in the evenings: a two-way speaker box that allowed customers to stay in their car while ordering, making his restaurant a true drive-thru experience.

Fun fact: There are 5 In-N-Outs that do not have a drive-thru lane.

Lots of people love In-N-Out — sometimes too much, like Paris Hilton who blamed her DUI on an In-N-Out craving. Chefs Gordon Ramsay and Thomas Keller are among the self-professed fans of the burger. Julia Childs was another serious devotee. Hard to believe, but she actually carried a list of locations in her purse, and even had her assistant bring her burgers while she was in the hospital recovering from knee surgery.

More In-N-Out trivia: If you’re an In-N-Out fan, you probably already know about the famous crossed palm trees that are outside almost every location. Harry Snyder got the idea of planting them as a way of marking his “treasure.”

Keto-Friendly Burgers at In-N-Out

In-N-Out’s burgers are 100% American beef with no fillers, additives or preservatives. In-N-Out is keeping up with the times and their burgers are available “protein-style” meaning with a lettuce bun.

The burger as listed on the menu with lettuce, tomato, an onion slice and the secret spread will run you 8 net carbs. This count is the same whether you go for the original, the cheeseburger or the Double-Double®. You can easily drop a couple of those carbs by passing on the onion and tomato. Their signature spread is a blend of mayo, ketchup and sweet relish and you will definitely save on carbs by giving it a miss, but then you may have to ask yourself, why go to In-N-Out at all?

  • Hamburger with Onion, lettuce bun (8 net carbs, 17g fat, 16g protein)
  • Cheeseburger with Onion, lettuce bun (8 net carbs, 25g fat, 18g protein)
  • Double-Double®with Onion, lettuce bun (8 net carbs, 39g fat, 33g protein)

The Not-So-Secret Menu at In-N-Out for Low Carb Eaters

You can get up to 4 hamburgers as one ‘sandwich’ (even when you’re foregoing the bun). So, you can order a 2x2, a 3x3 or a 4x4, meaning 2 burgers and 2 slices of cheese, etc. (Side note: they used to accommodate larger requests, but it got shut down after someone ordered a 100x100). Given how friendly and accommodating In-N-Out’s staff is, you could probably even order a 2x4 (meaning 2 burgers and 4 slices of cheese) or a 4x2, or any other combination. Four burgers probably isn’t the best idea for health reasons, but it’s available.

You can also order your bun-less burger with extra lettuce and the spread on the side, giving you the control of how much spread winds up on your burger.

A Flying Dutchman is 2 patties with 2 slices of cheese melted in between. The ultimate low-carb treat.

Another popular option is to order your burger “animal style,” which includes extra spread, pickles, and grilled onions. This one will add a few carbs to your count, although how many is a secret.
