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.

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. Just made these! They were delicious! Thanks for the recipe! 🙂 I ended up not measuring out the zucchini and cauliflower to exactness, which is why I am thinking they fell apart when I tried to pan fry them! I did, however, add more coconut flour and instead baked them on baking paper. No oil was needed. They came out perfect! I enjoyed them greatly this way! Loved the recipe!

  2. Amazing recipes. I am glad that I found your blog as I got new snack ideas from it. My daughter always wants new snacks in her tiffin and now I can make it for her. Keep sharing such tasty recipes with the foodies.

  3. 5 stars
    My daughter has to eat a dairy and gluten free diet. I came across this page looking for inspiration and decided to make these for the whole family – even my meat loving husband.
    They were absolutely delicious! I made the egg free variety and they held together wonderfully with gluten free flour. Thank you so much for the recipe – we will definite be making them again!

  4. Amazing!!!! i’m not a huge cauli fan but these are delish! I used flax eggs and turned them into ‘falafel’ balls. HELLO salad!

  5. What do you think about buying Cauliflower rice and using that instead of having to go through the process of blending and squeezing?

  6. 5 stars
    Hi Just cooked the vegan ones, I used coconut flour (Keto) & added equivalent 2 eggs (vegan egg replacer).
    I found only one held up, in a patty the rest got a bit crumbly but none the less was very delicious.
    Maybe need to add more egg repacer
