Last year I started noticing cauliflower-crust pizza showing up on healthy cooking blogs, but I didn’t pay much attention to the idea until a few readers wrote and said they were sure I would love it.  One person sent me a link to this recipe from Eat. Drink. Smile. and that’s the one my nephew Jake and I used as our starting point when we decided to experiment with this Cauliflower-Crust Vegetarian Pizza with Mushrooms and Olives.

It took us three different tries and the addition of both almond meal and grated Parmesan cheese to get a low-carb crust that we thought was about as crispy and bread-like as you could get when the main ingredient was cauliflower, but we both loved this final version of Cauliflower-Crust Vegetarian Pizza. I’m not sure this will ever replace regular pizza for some people, but if you’d like to try a pizza crust that’s low-carb, gluten-free, and more nutritious than regular crust made with flour, I think you’ll be pleased with this version.

What Equipment Do You Need to Cook Cauliflower Crust Pizza?

I have a pizza stone for the grill (affiliate link) and that seemed like the perfect way to cook pizza when it was hot outside, but the inspiring version was cooked in the oven so that will work too. Cooking times will be slightly longer if you don’t use a pizza stone. You’ll want to use a very hot oven, especially if you’re not using a pizza stone.  If you have an oven with a convection setting, that would be great for this recipe.

How to Make Cauliflower-Crust Vegetarian Pizza:

(Scroll down for complete printable recipe, including nutritional information.)

  1. Before you start to make the crust, start heating your pizza stone on the grill or in the oven. (If you don’t have a pizza stone, just heat the grill or oven.)
  2. You only need one cup of cauliflower for a crust, but we were going to make several versions, so we buzzed 1/2 large cauliflower in the food processor until it was finely chopped.
  3. Put 1 cup finely chopped cauliflower in the microwave and cook until the cauliflower is soft, 7-8 minutes for my microwave.
  4. I had a coarsely-grated mozzarella blend, so I used the food processor to chop it up so it would mix into the other crust ingredients better.  (This is way more cheese than the amount used for one pizza!)
  5. Combine the cooked cauliflower, cheese, almond meal, grated Parmesan, oregano, garlic powder, salt and a beaten egg to make the crust.
  6. Spray a sturdy cookie sheet with nonstick spray and then use your fingers to form the crust, spreading it as thin as you can get it.
  7. When your grill or oven temperature reaches 450F/230C, start cooking the crust (on the pizza stone if you have one.  (If you’re cooking on the grill without a pizza stone, heat the entire grill and then turn the heat off on one side too cook the crust.)
  8. While the crust cooks, cook the mushrooms and slice the olives.
  9. Take the crust out when it’s firm and lightly browned. Cover the crust with desired toppings.  We used low-sugar Rao’s Pizza Sauce (affiliate link), a small amount of finely grated Mozzarella, sauteed mushrooms, and black olives.
  10. I put the pizza back on the grill for about 5 minutes more to melt the cheese and heat the toppings, but if you’re cooking in the oven you can do this under the broiler.

Cauliflower-Crust Vegetarian Pizza with Mushrooms and Olives

Yield 2 servings
Prep Time 25 minutes
Cook Time 20 minutes
Total Time 45 minutes

This Low-Carb Cauliflower-Crust Vegetarian Pizza with Mushrooms and Olives can be cooked on the grill or in the oven.

Ingredients

Crust Ingredients

  • 1 cup finely chopped cauliflower (chop in food processor or grate with a cheese grater)
  • 1/2 cup finely grated mozzarella cheese
  • 5 T almond flour
  • 3 T finely grated Parmesan cheese
  • 1 tsp. dried oregano
  • 1/2 tsp. garlic powder
  • pinch of salt
  • 1 egg, beaten

Pizza Toppings

  • 1/4 cup Rao's Pizza Sauce (see notes)
  • 3 T finely grated mozzarella cheese
  • 4 oz mushrooms, sliced and cooked
  • 2 tsp. olive oil
  • 1/4 cup olives, sliced in half (or more)

Instructions

  1. Turn on the oven or grill, place the pizza stone inside (if using), and preheat grill or oven to 450F/230C.   (If you don’t have a pizza stone I might let the temperature get slightly higher.)
  2. Use a food processor or the large side of a cheese grater to finely chop the cauliflower, until it resembles small kernels of rice.
  3. Put the cauliflower into a bowl and microwave until it’s cooked through and soft, about 7-8 minutes.  (Don’t add water; the cauliflower will release moisture.)
  4. While the cauliflower cooks, slice the mushrooms, heat the oil in a large frying pan, and cook mushrooms until they’re soft and cooked through. Slice olives in half lengthwise.
  5. If you don’t have finely grated Mozzarella, I would buzz it a few times in the food processor so it’s more finely grated.
  6. In a small bowl, combine the cooked cauliflower, 1/2 cup finely grated mozzarella, almond meal,  Parmesan cheese, dried oregano, garlic powder, and salt.
  7. Beat the egg with a fork and then mix it into the other ingredients, combining them well.
  8. Spray a heavy cookie sheet with non-stick spray. Form the crust ingredients into a ball and place on the cookie sheet, then use your fingers to form the crust, spreading it out as thin as you can get it.
  9.  Put the cookie sheet on the pizza stone in the oven or on the grill and cook with the door or lid shut until the crust is firm and lightly browned, about 13-15 minutes.  (If you’re cooking this crust on the grill without a pizza stone, you will need to preheat the entire grill, then turn off one side and cook the pizza on that side, using indirect heat from the side that’s still turned on. This will probably add a little to the cooking time.)
  10.  When the crust is done, spread with pizza sauce, sprinkle with cheese, and arrange cooked mushrooms and sliced olives on top.
  11.  Put pizza back on the grill to melt the cheese and warm the toppings, or turn the oven to broil and cook it under the broiler for about 3-4 minutes.
  12.  Serve hot. This reheats well, and is even good cold for breakfast!

Low-Carb Diet / Low-Glycemic Diet / South Beach Diet Suggestions:
Low-Carb Cauliflower-Crust Vegetarian Pizza would be an approved recipe for most low-carb and low-glycemic diet plans as long as you use low-sugar pizza sauce. For the South Beach Diet there’s quite a bit of fat in this pizza from mozzarella cheese, Parmesan cheese, almond meal, and olives.  I would consider this a “once-in-a-while-treat” and limit myself to half the pizza shown here for phase one or two of the South Beach Diet.

    55 Comments on “Cauliflower-Crust Vegetarian Pizza with Mushrooms and Olives”

  1. I made this last night substituting whole wheat flour for the almond meal. It worked very well.

    A friend had tried another recipe for cauliflower crust and was not impressed. This was wonderful. My husband loved it as well.

    I'm going to share the link on my blog this weekend, I got a lot of interest on it from the photo I posted on facebook!

    Thanks for an awesome, healthy and easy recipe…I have another cup of cauliflower processed and ready to go, so it looks like this will be dinner again sometime this weekend.

  2. Claire, I don't know but I'm doubtful you can get it to hold together without cheese and egg, because you need something to hold the cauliflower together. You might try googling "vegan cauliflower pizza" to see if anyone has tried it.

  3. wondering if Heidi every tried this with Daiya cheese. My son doesn't eat wheat/ dairy/ egg but loves pizza…

  4. I'll give it a try this weekend and report back!

  5. I haven't tried it with anything else, but if you don't need it to be gluten-free it might work with flour, or maybe quinoa flour or some other type of flour would work. I can't say for sure though.

  6. Is there anything I can substitute for the almond meal? I have everything else but that in the house.

  7. I haven't made it in the oven, but since my grill has a temperature gauge the same as the oven, I think the cooking time would be about the same. I would check it a few times to make sure the edges aren't getting too done.

  8. I may have missed the information earlier but roughly how long does the crust take to cook in just the oven?

  9. Wow! I just made Chinese "faux" fried rice using cauliflower and now I am hooked on substitutions. I cannot wait to try out this 'faux' pizza crust.

  10. That's great; thanks for the feature.

  11. On Fridays, I share my favorite food finds in a series called Food Fetish Friday – and I love the crust on this cauliflower crust you created for this pizza so I'm featuring it as part of today's roundup (with a link-back and attribution). I hope you have no objections and I'm happy to be following along with your creations…

  12. Glad you liked it. I do think Flaxseed meal is gluten free, but I'm not positive.

  13. There is none left over for breakfast around here! Yum!! My store didn't have the Almond Meal, so I subbed Flaxseed Meal. I don't know if that's gluten-free but it worked well 🙂

  14. McGirl, so glad you liked it. I had to take pictures of mine before I ate it, so that must have been why I didn't notice the crust being soft at first!

  15. We made this tonight, though with wild variation on the toppings and a bit of added flax in the crust – so good!!!! My only addition to the recipe would be to let the pizza rest for five minutes after the final bake; when we first served it up the crust had become a bit soggy, but a few minutes later (after we'd devoured our first servings) it had hardened up again. I've tried a couple of other cauliflower crusts but this is the best by far! Thank you!

  16. Thanks I'll try it! I probably skimmed the recipe too fast and missed it.

  17. I thought I had made it clear in the recipe that you can make it in the oven or without a pizza stone. You may have to cook the crust longer or at a slightly higher temperature but it will definitely work.

  18. Would love to try this, BUT . . . don't have a grill or a pizza stone– can I still make it? I have a Pampered Chef clay stone pan and a regular oven. Will it work?

  19. I'm happy that so many people are interested in trying this! I think there can be endless variations of this recipe.

  20. That cauliflower crust pizza is looking really good! I have been wanting to try the cauliflower crust for a while now!
