Top 10 Best Keto In-N-Out Options

One great thing about eating at In-N-Out is the eatery’s simple burger menu, made up of just three burgers, which are then adapted to result in various other burger offerings.

The simple In-N-Out burger menu means you can save time when you next stop by since you do not have to sift through a long menu of confusing options trying to find the most keto-friendly meals. 

Here’s a handy list of keto In-N-Out options you can order for your new or ongoing keto campaign. 

In-N-Out Keto Burgers

In-N-Out has a special way of making keto-friendly burgers by replacing the buns with a lettuce wrap. And it feels much like the bun, so you probably won’t miss the bun at all!

The lettuce wrap burgers are what In-N-Out calls the “protein style”. As you’ll notice, various keto-friendly burgers on its menu are protein-style adaptations of the three main burgers. 

Other than the three main In-N-Out burgers – hamburger, cheeseburger, and Double Double – you can order any of the following burger varieties to meet your keto diet needs. 

Plus, you can make each burger more keto-friendly by ditching the In-N-Out burger sauce or spread.

1. Double Double Burger

The Double Double burger comes with toasted buns, two American cheese slices, two American beef patties, freshly sliced or grilled onions, lettuce, In-N-Out Spread, and sliced tomato. 

To make the burger more keto-friendly, you can skip the bun, onion, spread, or tomato.

2. Double Double with Onion – Protein Style

Top 10 Best Keto In-N-Out Options

The protein style of the Double Double with Onion burger is the bunless burger wrapped in lettuce instead. It comes with cheese, beef patties, onions, tomato, and spread. 

You can make the Protein Style Double Double with Onion burger even more keto-friendly by asking them to make it without the sauce or spread. 

That said, the spread isn’t too damaging as it only contains 2g net carbs per pack. To be on the safe side, you can have the burger made without the spread and instead have the spread served separately. 

The Double Double with Onion packs 41g fat, 39g total carbs, 3g dietary fiber, 37g protein, and 670 calories, 370 of which are from fat. 

The protein style of the Double Double with Onion weighs 362g and delivers 11g total carbs, 3g dietary fiber, 33g protein, 39g fat, and 520 calories, 350 of which are from fat. 

3. Hamburger with Onion 

The Hamburger with Onion delivers 390 calories (170 from fat), 39g total carbs, 3g dietary fiber, and 16g protein. 

The carb count of 39g for this hamburger is on the high side, so you might want to make it keto-friendly by ditching the high-carb bun. You can replace it with the lettuce-wrapped hamburger instead. 

The keto-friendly protein style adaptation of the Hamburger with Onion weighs 275g and packs 240 calories (150 from fat), 17g fat, 11g total carbs, 3g dietary fiber, and 13g protein. 

4. Cheeseburger with Onion

Top 10 Best Keto In-N-Out Options

The Cheeseburger with Onion contains 480 calories (half of which are from fat), 27g fat, 39g total carbs, 3g dietary fiber, and 22g protein. 

Again, 39g total carbs may be on the high side, so forego the bun or just order the lettuce-wrapped version of the cheeseburger. 

The cheeseburger contains a toasted bun, one slice of American cheese, one American beef patty, grilled or freshly sliced onions, lettuce, In-N-Out Spread, and a tomato slice. 

The lettuce-wrapped Cheeseburger with Onion packs 330 calories (220 from fat), 11g total carbs, 3g dietary fiber, and 18g protein. 

5. Flying Dutchman

The Flying Dutchman is simply two freshly grilled ground beef patties acting as the bun on the outside and two American cheese slices in between. It’s just cheese and meat without the bun. 

You can complete the burger by topping it with onions, lettuce, tomatoes, and mustard pickles as per your preference. If you would like, you can also order it protein style. 

6. 3×3 Burger

The Not So Secret Menu’s 3×3 or Triple Triple burger is made up of hand-leafed lettuce, spread, three slices of American cheese, a freshly baked bun, tomato, and three American beef patties. 

The 3×3 burger is available with or without onions, depending on your preference. You can also order the lettuce-wrapped version of the burger to keep the carbs content even lower. 

The protein style 3×3 burger packs about 710 calories, 11g total carbs, 53g fat, 3g fiber, 8g net carbs, and 48g protein when it comes with onions. 

7. 4×4 Burger

The Quad Quad or 4×4 is another of In-N-Out’s Not So Secret Menu offerings. It consists of four American beef patties, lettuce, spread, tomato, four slices of American cheese, and a freshly baked bun. 

Like the 3×3, the 4×4 comes with or without the onions. Its bun can also be replaced with a lettuce wrap, making it more keto-friendly. 

The protein style 4×4 with onion packs 900 calories, 3g dietary fiber, 67g fat, 11g carbs, 8g net carbs, and 63g protein. 

8. Mustard Grilled Patty Burger

When you next stop at an In-N-Out joint, you might want to try a Mustard Grilled Patty burger. The burger patty is smeared with mustard before grilling, resulting in a unique flavor.

Ask the In-N-Out team to mustard-grill the burger to get an irresistible flavor. Also, feel free to order the protein style adaptation of the Mustard Grilled Patty burger. 

9. Whole Grilled Onion Burger

As the name suggests, the Whole Grilled Onion burger features a whole slice of grilled onion rather than the usual raw onion slice. 

You can ask the In-N-Out team to prepare your burger with whole grilled onions to add a little bit of flavor to your burger. If you like a twisty appeal to a meal, you can even mix raw and grilled onions!

10. Animal Style Burger

The Animal Style burger is any burger of your choice containing tomato, lettuce, grilled onions, pickles, spread, and mustard-grilled beef patty.
