Keto Portabella Pizzas

Is there anything better than cheesy, full flavored pizza that keeps you on your keto diet? We think not. These keto portabella pizzas do the trick and take only 25 minutes from start to finish!

Here's how this idea came around. You see, I love, love, love marinated and grilled portabella mushrooms. My husband - not so much. But, he would eat just a little bit because he knows mushrooms are so good for him.

So, I thought... what if I use portabella mushroom as a pizza CRUST?

Because of the melty cheese, I knew grilling wasn't the best option. I mean, who wants to clean their grill afterwards? Not this girl!

I also knew that I needed to be careful about cooking the portabellas too long. Past experience had taught me that overcooking them caused them to release a lot of juices.

The end result was incredibly satisfying and a big hit with both of us and the family we had to stay here at the time. Keep reading for the full keto recipe as well as some tips on making these portabella pizzas even lower carb.

Easy Keto Pizza

The best part about this keto recipe is how easy it is. All you need is some no-sugar-added pizza sauce, cheese and your favorite low-carb toppings.

Get the recipe for my low-carb pizza sauce here. It's quick and easy to make and freezes very well.

However...

If you're following a strict keto diet and keeping carbs very low, use one of these options instead of pizza sauce:

• Olive oil, salt and pizza seasonings
• Ranch dressing (no sugar added)
• Cream cheese or goat cheese mixed with pizza seasoning
• Spinach artichoke dip

Any of these pizza sauce substitutes work great and are delicious. It's also a great way to mix things up and bring in some variety!

Here's the ingredients you'll need to whip up these keto pizzas...

📖 Recipe

Keto Portabello Pizzas

These keto pizzas are rich and satisfying. Each pizza is approximately 5 total carbs or 4 net carbs excluding the pizza sauce. There are so many keto options for pizza sauce, I opted not to include it in the final count. You can use very low carb options such as alfredo sauce, olive oil & herbs, ranch dressing or even spinach artichoke dip. Enjoy!

Author: Tara Wright

Ingredients

• 4 large Portabello Mushrooms
• .25 cup Olive Oil extra virgin
• 1 tbsp dried basil (or fresh)
• 3 cup whole milk mozzarella cheese
• Pizza Sauce of choice (low carb pizza sauce, alfredo sauce, ranch dressing, olive oil, ect)

Instructions

• Preheat oven to 350 degrees (325 degrees if using convention)
• Wash your portabella mushrooms and gently remove the stem from each mushroom. Discard the stems.
• Brush olive oil onto the bottom of the mushrooms. The mushrooms act as a sponge and really soak in the oil. Then, sprinkle on dried basil or pizza seasonings. Flip mushrooms over and arrange on a baking sheet.
• Now it's time to assemble the low carb pizzas!
• Lightly cover the inside of the portabella with a pizza sauce of your choice. You can use a traditional sauce or lower carb options such as alfredo sauce, ranch dressing, olive oil, ect.
• Top with cheese, herbs and toppings of your choice.
• Bake in a preheated oven for 8-10 minutes. If cheese has not yet melted to your satisfaction, broil the mushrooms on your lowest broil setting for an additional minute or two.

  Note that cooking times vary based on the size of the mushroom. The trick is to avoid over cooking them as they will start releasing a lot of liquid. So, if there's a lot of liquid on your plate or baking dish, cut the cooking time next time.

Notes

Note that the pizza sauce is NOT included in the nutrition facts because there are so many different options! See the blog post for suggestions.

Making Lower Carb Pizza

Now, I have not included a pizza sauce in the final nutrition counts. This is because everyone will use a different sauce option... same with toppings other than cheese.

You can do so much with these pizzas to keep them as low carb as possible. The lowest carb option will be mixing some high quality extra virgin olive oil with a tablespoon of pizza seasoning. Then drizzle this over the portabella's in place of pizza sauce. Yummm....

Tip: When selecting a pizza seasoning, read the ingredients list and make sure there isn't sugar hiding in there. When we went keto, we found all kinds of sugar hiding in our seasoning mixes. We gave a lot of stuff away and trashed the older stuff. It's amazing where you'll find sugar hiding!

Keto Chili

Meaty Keto Chili

This is absolutely the best keto chili on the internet. 

A few of the techniques I am using here I learned from my obsessive “Americas Test Kitchen” watching. We bloom the spices to bring out the flavor and we brown the ground beef in spices to pull a meatier flavor out.

This recipe does also work in a Crock-Pot; But it tastes way better if you take the time to follow the steps 🙂
