While we don’t recommend eating fast food often on a keto diet (or any diet for that matter), Jack In The Box does offer easy-to-customize keto options. Our favorite low carb Jack In The Box meals are a bunless Extreme Sausage Sandwich and bunless beef or grilled chicken burgers.

Like every fast food chain, there are plenty of foods on the menu that you’ll need to avoid. We’re here to help you make a smart low-carb choice. Just follow these tips and suggestions.

Tips For Ordering Low Carb at Jack In The Box

Jack In The Box is much better than other fast food chain restaurants at providing decent opportunities to turn your food into a low-carb meal. It’s a much better place to eat than say a pizza restaurant or a fried chicken place.

They have salads, sandwiches, burgers, and even breakfast.

If you accidentally leave a meal at home, then Jack In The Box can be a good stand-in, but we don’t recommend making a habit out of eating fast food. We recommend looking at the menu before you go so that you can make an educated choice.

Lowest Carb Meals

Here are our top choices for lowest carb meals at Jack In The Box according to the nutrition information:

  • Chicken club salad with grilled chicken (7 grams net carbs)
  • Grilled chicken salad (8 grams net carbs)
  • Bacon, egg and cheese biscuit (hold the biscuit)
  • Bacon and egg chicken sandwich (if available; hold the bun and sauce)

You can find all of the nutritional information on the Jack In The Box website, which is a good way to track your macronutrients if you need to stay under 20 grams for the day.

We also like that Jack In The Box lists all the ingredients in their food. You can take a look at their menu on their website. 

Here are some tips to help you keep it low-carb at Jack in the Box.

#1. Get a breakfast sandwich and hold the bun

Jack In The Box offers breakfast anytime of the day. Breakfast sandwiches are a good way to eat low-carb because they often feature meat, cheese, and eggs. You just have to remember to ask them to hold the bread or toss it as soon as it comes. Breakfast sandwiches are also less likely to have sauce on them like a regular sandwich or burger would.

You can check out the breakfast menu at Jack In The Box here. Stay away from the hashbrowns, pancakes, and burritos, which are hard to eat the insides only out of. Stick with a croissant, sandwich, or biscuit instead because it’s easier to toss the bread. It doesn’t look like Jack In The Box offers freshly brewed coffee, but you can get unsweetened iced tea to meet your caffeine needs.

#2. Order a side salad with your bunless burger

Jack In The Box offers a nice selection of burgers and salads. Pair them together and you have a great low-carb meal. Choose from one of their many burgers and ask to hold the bun and any sauce that comes on it.

Then, ask for a side salad made without any dressing instead of fries or onion rings. You can ask if they have oil and vinegar as a dressing option, but most fast food places don’t. So, you’ll likely have to eat your salad plain. Be sure to hold the croutons, too.

If you don’t like eating your salad plain, then be sure to consult the nutrition guide to determine how many carbs are in your dressing of choice. Here is a list of the salad dressings at Jack in the Box and how many carbs are in one serving:

  • Creamy southwest dressing: 3 grams carbs
  • Low fat balsamic vinaigrette dressing: 3 grams carbs
  • Ranch dressing: 5 grams carbs

By the way, the gourmet seasoned croutons contain 9 grams of carbs and the spicy corn sticks contain 8 grams of carbs. So you can subtract these from your salad if you want to know the net carbs of your meal.

#3. Avoid the combo meals

Lots of fast food restaurants offer different types of meals on their menu. It’s a good way to get a lot of food for not a lot of money.

Unfortunately, you can’t eat any of the stuff that comes with a meal, such as fries, onion rings, tacos, and a drink. You could always eat the insides only out of a taco. But Jack In The Box offers lots of other low-carb options so you shouldn’t need to resort to this.

We recommend sticking with a single burger, sandwich or salad, and don’t try to make a combo meal out of it. If you choose to order a meal, make sure you hold the bun and sauce on your burger as well as any sauce that comes on the taco. If given a choice, then pick a hard shell taco over a soft shell as these are easier to eat the insides only out of. Also, hold the fries and choose an unsweetened iced tea as your beverage of choice.
