As someone who LOVES a good veggie burger, transitioning to a ketogenic diet made it incredibly difficult to maintain this burger love.

Now, don’t get me wrong. I COULD still get my burger love. I mean, fast food chains are jumping on the vegan burger bandwagon, like Burger King (Hungry Jacks) and even McDonalds.

Alas, while vegan friendly, they are still a no-go for one who follows a vegetarian keto diet.

It was time to roll my sleeves up and come up with a meat-free keto burger, that happens to be low carb too!

Are veggie burgers keto?

Supermarkets and grocery stores are LOADED with a variety of veggie burgers. Unfortunately, barely any of them are suitable for a paleo or grain free diet, let alone a keto diet!

Brands like Morningstar and dr.praeger’s veggie burgers are not keto-friendly.

Like many other brands, they are primarily made up of legumes or beans, which, while healthy and full of fiber, are not suitable for any of those diets.

Even though they are relatively high in protein, they also contain lots of carbs, and cannot be considered a low carb food.

Can you eat veggie burgers on keto?

YES. You CAN eat veggie burgers on a keto diet and we are here to prove it!

My homemade zucchini cauliflower fritters are thick and juicy, just like a burger, and 100% keto-friendly and low carb.

Granted, they won’t be as meaty or tender as a ‘real’ burger, but it’s 100% better than frying a mushroom and calling THAT a veggie burger.

Why make these keto zucchini fritters (keto veggie burgers!)

These Keto Zucchini Cauliflower Fritters are very different than those nuggets. For one thing, they are fritters, not nuggets because the fritter shape is much more mature.

Also, I simplified the ingredient list from 10 down to just 4 ingredients (+ salt and pepper) because 10 was way too much measuring and fuss. Plus carrots are so sweetly snack-perfect a veggie on their own, no need to hide them in fritter form.

I switched from baking to pan-frying because hello crispy delicious exterior.

I don’t know about you but I would much rather leave the oil out of the mixture itself and save it for creating extra flavor in the pan.

Plus it ended up being less oil in the end anyways.

But most importantly, they don’t fall apart if you so much as look at them funny because I remembered the egg and worked out an egg-free version too… because we don’t want our vegan friends to miss out!

How to make the BEST keto zucchini cauliflower fritters

Step 1- Prepare the vegetables

For either version, there are a few important steps when it comes prepping the veggies. These fritters get their green from zucchini. You can either grate the zucchini by hand or let your food processor do the work for you.

The other, more discreet veggie is cauliflower. You want to use already cooked cauliflower because the few minutes of pan-frying will not be enough to cook the cauliflower completely. If you are using frozen cauliflower, that step is already done for you. If you are using fresh, simply steam it for 5 minutes or so until just soft.

After both the veggies are grated, it is crucial that you squeeze out as much extra liquid as possible so you don’t end up with soggy fritters. A towel works, but personally, I love using a nut milk bag if you have one. I find it is even more effective and keeps your dishtowel from turning green.

Step 2- Add the other ingredients and mix! 

For the version with egg, you will then add a couple of eggs, a quarter cup of coconut flour, and salt and pepper (plus any other seasonings you like).

For the egg-free version, instead of using flax egg I just switched up the flour to a more naturally bind variety: all-purpose or a gluten-free blend. 

Step 3- Fry the burgers/fritters! 

Both versions are equally easy to shape into burgers and cook on the stove-top, but I personally prefer the texture of the version with egg so if you are not vegan I recommend that one.

Cook the burgers for 2-3 minutes each side, before flipping and cooking the other side too, until golden.

For fritters (i.e. thinner patties), cook for less time (around 2 minutes each side).

How many net carbs are in a veggie burger?

Store-bought veggie burgers can contain up to 34 grams net carbs- and those are the ones with added fiber!

My homemade version contains just 1.7 grams net carbs!

Can you freeze keto veggie burgers? 

Leftover cauliflower zucchini burgers should always be stored in the fridge in a sealed container, to avoid spoiling. They will keep fresh for up to 1 week.

Freeze burgers for quick dinners or as part of a meal prep. Wrap cooled burger patties/fritters in parchment paper, and place in a ziplock bag. 

Frozen fritters/burgers will keep fresh for up to 6 months.

Servings: 8 burgers
Prep: 5 mins
Cook: 5 mins
Total: 10 mins


Original version

  • 1/2 head cauliflower approximately 3 cups, chopped
  • 2 medium zucchini
  • 1/4 cup coconut flour
  • 2 large eggs
  • 1/2 teaspoon sea salt
  • 1/4 teaspoon black pepper

Egg-Free version

  • 1/2 head cauliflower approximately 3 cups, chopped
  • 2 medium zucchini
  • 1/4 cup all-purpose flour can be gluten-free, if needed
  • 1/2 teaspoon sea salt
  • 1/4 teaspoon black pepper


  • Grate the zucchini in a food processor or high-speed blender.
  • Steam the cauliflower for about 5 minutes until just fork tender. Add the cauliflower to the food processor/blender and process until broken down into small chunks. Do not over process or it will become a mash.
  • Use a dishtowel or nut milk bag to squeeze as much moisture as possible out of the grated veggies. 
  • Transfer to a bowl and add the flour of choice, egg (if using), salt, pepper, and any other seasonings you like. Mix to thoroughly combine. Shape into small patties or burgers (I got about 8).
  • Heat up 1 tablespoon of coconut oil in a large pan. Add 4 fritters/burgers to the pan and cook over medium heat for 2-3 minutes per side. Repeat with the second half of the fritters/burgers. 
  • Serve with dipping sauce of choice or low carb burger bun.


Fritters can be refrigerated and are freezer friendly.

  1. These look delicious! And would be a fun change from my traditional crispy roasted veggies. But unfortunately I can’t stand ketchup, I’m weird I know! lol

  2. These sound really good! Im not a fan of chicken or meat type nuggets or fritters but these look right up my ally. I wonder if I can get my sister to try them? mmmm probably only if I smother them in nutella!

  3. I am going to try this recipe!!! Always looking for good healthy snacks! And I have zucchini in my freezer…..can I use that?

  4. I need to try this, the vegan version, to see how it all works together. I’ve been trying to figure out the proper ratio of egg substitiutes, but sadly sometimes they work, sometimes they don’t. I do have a lot of zuchinni in my fridge, so it’s a definite must! Thanks for the idea!

  5. I am allergic to coconut (and almond) but am trying to stay low carb. Can I substitute flax meal for the coconut flour? Is there another product you would recommend instead? These look delicious and I can’t wait to make if I can find a proper substitute! Thanks!

  6. I made these tonight for dinner. They were delicious! I did add a few ingredients though (sweet onions, mushrooms, roasted garlic, and red bell peppers – all sauteed). I also used brown rice flour and cooked them in olive oil. They were crispy and moist all a te the same time. I’m vegan, so no egg or egg substitute. The flour did the trick. Just make sure to use a gnon-stick skillet. My family loved them too! Next time I will make them for a party and create a dipping sauce.

  7. This recipe states it is Vegan. It looks delicious but, is not Vegan because it has eggs. Vegans do not eat eggs.

    1. Well aware that vegans don’t eat eggs. With all due respect, you’ve clearly not read the post or recipe card. There is a very evident vegan option included.

      This recipe is vegan. Enjoy.

  8. These look delicious, but they aren’t vegan, as vegans don’t eat eggs. What do you suggest as a replacement in this particular recipe?

    1. With all due respect, you need to read the post before making incorrect statements. The recipe post clearly states an egg free version. I am well aware vegans don’t eat eggs.

  9. Do you think this would work with broccoli instead of zucchini? My kids already love zucchini, I’m looking for creative way so to get them to eat broccoli lol

  10. 5 stars
    These look amazing and I am very excited to try them, Arman. What is the delish sauce you had shown in the photograph above? I was thinking of creating a lemon, basil mayo version. I would love to hear what you use and try that recipe too. All your keto and paleo recipes look divine. Thank you for sharing! Aloha

  11. I made the keto version of these and just used coconut flour, it held together well. I also added some cumin to add a bit of a ‘meaty’ flavour. Topped with some smokey baba ganoush and wrapped in a lettuce leaf, they were so filling!! These are definitely in my rotation.
