A 100 Calorie Pizza That Will Rock Your Sox

July 18, 2011   38 Comments

You know what? It isn't that hard to make healthy pizza. Pizza would always be pretty healthy if we chose not to put 1/2 pound of cheese on every slice.

Portobello Mushroom Snack

Here on Snack Girl, I have featured English muffin pizzas, Triscuit pizzas, and even made over a frozen pizza to get readers to try a healthier version of pizza.

Well, do I have a solution for you. Make the pizza in a portobello mushroom cap!

Why would you do this?

  • only 22 calories of crust
  • tastes meaty and goes great with sauce and cheese
  • you don't have to make crust!

Yes, this is SO easy it is ridiculous and the taste is phenomenal. Now, the down side is that in my neighborhood a portobello mushroom is running about $1 each. But keep in mind the health benefits.

You are eating a 22 calorie mushroom instead of a load of crust (and it is gluten free)!

In the recipe below, I used diced fire roasted tomatoes to fill the caps. I like them because they already have some seasoning and they have texture - as compared with pizza sauce.

Also, I used fresh mozzarella because I love the creaminess. Feel free to use any cheese or tomato combo that you have in the house.

Kids will love making these and you can make them ahead to reheat later.

I have done these many times they taste amazing!!

This looks really good, I never thought of trying that before but I definitely will!

This looks amazing, also great for low carb diets.

Great idea! Looks great and so much healthier than traditional pizza.

That, and an Amstel Light. Now you're talkin!

This would be great if I liked mushrooms. :(

i realized a long time ago that i love pizza toppings more than pizza itself so i do the mushroom-as-crust thing all the time! (except i leave out the cheese)

for those that hate mushrooms, mix up spinach & egg whites & bake. top with sauce and return to oven until hot and bubbly. awesome!

OOHHH!!! My favorite pizza is spinach and mushroom, and since I'm allergic to gluten, dairy, corn and tomatoes, the only pizza I can eat is about $5 for 2 pizza crust and I never put tomato sauce on my pizza. I will definitely have to try this one! Sounds yummy!

these look awesome! can't wait to try them!

Oh, Tea-bag! Thanks for the idea about spinach and egg whites (or Egg Beaters, for that matter) as an alternative to the mushrooms! I am a hater of the 'shroom, and was really disappointed that I couldn't have a pizza make-over too! Thanks!

I had this last night. Didn't put tomatoes on it but melted WW pepperjack cheese. Very tastee.

This is a super recipe. I'll bet you could also do this with the smaller mushrooms as bite-sized party food and they would be delicious!

Snack Girl,

I enjoy your site and the ideas. Saying that, I am looking for snacks that do not contain tomatoes or tomato products or wheat or corn; can you help?? Thank you

I love making pizzas like this especially to pack for my lunch at work. I either use mushrooms or lavash bread that is 1 PPV. I bet you can use sliced eggplant or polenta too if you aren't a mushroom eater.

I've got a mess of them! You can use mushroom caps and put spinach and cheese as a topping, you can use black beans, chicken and green chilies as toppings, you can do just about anything with this recipe. I've been gluten, dairy, corn and tomato free for years now and have tons of secrets! You can contact me through my website for some tips.

Tea bag....can you go into more detail for the non-mushroom lovers!?

This is an awesome idea! Love it and yes, so many things can be put into the mushroom! I loved stuffed mushrooms but never thought to make it "pizza like". Thanks so much!

Oh, YUM, I love portabellas...

Snack Girl: Do you leave the gills in?

PS I think that the Trader Joe's sundried tomatoes (the dry kind not in oil) would make a great addition and not add to the moisture.

I love this idea! I need to worry about sodium, and the portabello takes care of that part for me. I make my own sauce with low-sodium tomatoes and tomato paste. Real (as opposed to artificial, I guess) mozzarella has a little less sodium...just have to measure out a limited amount...and it's guilt free pizza for lunch. Thank you!

This is genius!

These look great, I love pizza and cant wait to try this! Btw, I love your blog, I’ve been reading it for over a year now. I just started my own food review blog and put you on my blog list. You can check it out here, thanks!

Hey a half a pound of melted cheese is good!! :) how about if it just didnt have calories.. This recipe looks excellent.


I just made this it was amazing!!!!i added some spinach and artichoke hearts YUMMMYY!!!

What a wonderful idea for healthy low calorie gluten free pizza. I often make healthy low calorie pizza at home by using tortillas for the crust - but look forward to trying this very soon.

Got excited until I saw it was made with mushrooms. I just can't handle that. Shoot!

HI, first time to your site. I like what i see! I LOVE Portobello mushrooms!!!!!!!! what a great recipe! I will be trying this one. Thanks, I have tried several different pizza crust recipes. one made w/ rice,another w/ cheese & eggs,another w/ almond&coconut flour, and w/ cauliflower. but this one w/ the portobellos sounds like a winner and less work. now if it just passes the family test!?

Thanks so much!

This is such a great idea!. So great for those trying to be low carb and gluten free. thanks for all your super recipes!

Wow! This is a super idea! I am definitely going to try these pizzas asap! So glad to have found your site! Thanks for the ideas!!

made these for dinner tonight, SO delicious and much more satisfying than pizza with crust! I added a little bit of oregano on the top and that made them super yummy!

I used regular sliced mushrooms in place of portobello mushroom caps. I didn't have any portobellos and the sliced mushrooms are much cheaper. I sprayed a cookie sheet, spread the mushrooms on the bottom of the pan for my make-shift crust, drained the fire roasted tomatoes, and sprinkled them with mozzarella cheese. I added a little bit of diced leftover chicken fajita meat. It was divine. It is a good fix for a pizza craving! Love it!

Thanks for the photo teaser of these mushrooms at the bottom of today's post (Aug. 14, 2012)! Being relatively new to the website, I've missed a lot of what came before, even though I do a fair bit of exploring. These look like just the ticket for dinner tonight - just happen to have some mushrooms that need using, fresh tomatoes and fresh mozzarella as well. Thanks!

Looks really tasty and am definatly going to try this, but not sure if it would help that "pizza craving" I find when I'm craving its the bread that forfills it.

You will want to lightly scrape out the fan.

Also, I baked at 425 degrees, 10 minutes cap side down, then turned mushroom over, sprinkle with sea salt, return to oven for 10 minutes more. After, 20 minutes of baking I filled the cap with sun dried toatoes, and parm/mozzarela mixed cheese. Delicious, and fully cooked not soggy!

Yummy! I'm going to try this.

My favorite Friday-night dinner is veggie pizza on a tortilla shell, whatever kind you prefer works. Bake the tortilla for about 5 minutes (called par-baking) before you put the toppings on if you like the crust to be crispy.

I made portabella mushroom pizza often. I take out the caps and microwave the mushrooms for approximately 1 minute. I then add either sugar free tomato sauce or tomato puree and some low fat mozzarella cheese and back in the microwave for a few seconds until cheese melts.
