Best Bunless Burger Options for Keto

Best Bunless Burger Options for Keto

Updated February 15, 2021

You’ve been in a spot where you are starving and your only option is fast food. Well, we’ve got your back. Here are some amazing bunless burger options for you keto-maniacs out there.

We are sticking to the value menu burgers. These are usually under $2 per and are on the specially assigned “value menu” section of the menu.

Keep in mind I am only doing fast food restaurants that are near me. These are burgers I have tasted and can judge. If your favorite fast food join is not on here, I apologize!

The criteria we are going to use are: price, size, net carbs and taste. I stole this criteria from our heroes at Food Central TV, which if you haven’t checked out yet, do yourself a favor and check it out. Of course they don’t give a crap about keto so I added the net carbs category myself. Nutritional information will be pulled from My Fitness Pal.

The restaurants we are putting in the running are: Wendy’s, McDonald’s, Burger King and Hardee’s (or Carl’s Jr. depending on where you are geographically). We will be judging their standard double cheeseburger. No bacon, no extras. If toppings are available we will take them on, outside of ketchup due to the carbs in it.

Burger King Double Cheeseburger

The first one we are reviewing is the double cheeseburger from Burger King. We are using stock images because I can make any photograph look awful. As you know, the burgers don’t look this good. Also they don’t have buns when we eat them.

I rate Burger King as one of the top top fast food burgers. Love the charbroiled taste. The serving size is 135g, but that includes the bun. We will not have the exact size of each double cheeseburger due to the buns, but that shouldn’t cause a problem. I ate this one first because I knew I’d like it. I’ll like them all, though. What’s the saying? Fast food burgers and sex are the same. Even when they’re not very good, they’re still good. OK, I just made that up, but it makes sense, right? I’ll stop now.

So here are the hard numbers for the bunless BK double cheeseburger.

Toppings: pickles, onion, American cheese, mustard

Price: $1.69

Calories: 220

Carbs: 1g

Size: A very nice sized burger.

We start off with a championship contender. BK is going to be tough to beat.

Wendy’s Double Stack

The second burger is the Wendy’s Double Stack. Wendy’s is tricky because they have so many variations of burgers they have. Per our judges decision, this is their official value menu double cheeseburger.

This is a very good burger as well. I put Wendy’s and BK near the top of fast food burgers. Just a better quality of meat. Never frozen as they say at Wendy’s. It says no mustard on the nutrition facts, but that’s not necessary. The stats are still accurate as mustard has basically no nutritional value. Here are the stats:

Toppings: American cheese, onion, pickles, mustard

Calories: 260

Price $1.99

Carbs: 1g

Size: Not quite as big as Burger King’s double cheeseburger. So far it’s in 2nd place.

This one is also a championship contender. Or maybe I just love burgers. Either way so far, so good.

McDonald’s Double Cheeseburger

Like Wendy’s, this one was also tricky. They have a McDouble and a double cheeseburger. We went with the double cheeseburger as it falls more in line with the price range of the other burgers.

If you are an American, I probably don’t have to tell you much about how a McDonald’s burger tastes like. Not quite as good as the other burgers, but still a very solid option.

Toppings: American cheese, pickles, mustard, onion

Calories: 280

Price $1.71

Carbs: 5g (ouch!)

Size: We’ll call it a tie with BK for the biggest burger yet.

McDonald’s trails in several categories, so it looks like their best finish could be third place.

Hardee’s Double Cheeseburger

Hardee’s has something called the “double cheeseburger” on their menu. How convenient. Also, they have a nutritional information calculator on their website. It’s like they knew they were going to be in this competition. I like it!

This burger surprised me. Could be a sleeper to win it all. Due to their inconvenient location compared to where I live, I rarely hit up Hardee’s. Also, they aren’t open 24 hours a day and I don’t drink till 4 a.m. Many of my Hardee’s trips happened at a much younger age at 3 a.m. No I didn’t drink and drive. I rode my magic carpet.

Toppings: American cheese, pickles, mustard, onion, pickles

Calories: 120

Price $2.51

Carbs: 4g

Size: 3rd place behind BK and McDonald’s

A very good burger. Not sure how it’s 120 calories. Might need to check with Hardee’s on that. The price is very high and there are some carbs, which are drawbacks.

So here is how we crown a champion. You get points for each category 1 to 4, based on where you finish.

Here are the totals. The number text to the maker of the burger is how many points they receive. For 1st place you get 4 points. In case of a tie, you split the extra point.


Burger King – 4

McDonald’s – 3

Wendy’s – 2

Hardee’s – 1


Burger King – 3.5

McDonald’s – 3.5

Hardee’s – 2

Wendy’s 1


Burger King – 3.5

Wendy’s – 3.5

Hardee’s – 2

McDonald’s – 1


Wendy’s – 4

Burger King – 2.5

Hardee’s – 2.5

McDonald’s – 1


Burger King – 13.5 points

Wendy’s – 10.5 points

McDonald’s – 8.5 points

Hardee’s – 7.5 points

And the winner is….

The Best Fast Food Value Menu Bunless Burgers for Keto

Burger King


Wow, that was fun. Of course it’s very objective. Any of these burgers are a great option when you are in a bind. Obviously, there are a few more carbs in Hardee’s and McDonald’s than you want. But if you go Wendy’s or BK you can house 5 bunless double cheeseburgers and be fine.

The bunless burger is an incredible tool in the keto tool box. No matter where you are you are a couple minutes of driving from getting one of these quick and easy keto bunless burgers.
