Portobello pizza is so tasty. It is the perfect healthy, low carb and keto substitute for real pizza.
Portobello pizza is the ultimate answer for pizza lovers who wish to eat healthy, keto and low carb. The portobello mushroom base is meaty and delicious, and the melty, cheesy topping is delightful, as one would expect.
How to make portobello pizza
Scroll down to the recipe card for the detailed instructions. You start by pre-broiling the mushrooms. The next step is to fill them with pizza sauce and cheese, top with your choice of toppings, and broil briefly to melt the cheese. That’s it! It’s an easy and quick recipe.
Since the mushrooms shrink quite a bit when we pre-broil them, it’s best to buy large portobello mushrooms – as large as you can find. It’s also best for this recipe to use flat portobello mushrooms, to help mimic a regular pizza crust.
How to prevent sogginess
The only challenge with portobello pizza is preventing sogginess. Portobello mushrooms, like all mushrooms, contain quite a bit of liquid, and the last thing you want is for them to release their liquid into your lovely pizza!
Here are my tips for preventing portobello pizza sogginess:
- Wipe clean, don’t wash the portobello mushrooms. If you wash them, they can absorb too much water.
- Remove the gills. They tend to release quite a bit of water (though I admit to not always doing this!).
- Pre-broil the mushrooms to release some of the water, then drain them, gill side down, on paper towels.
- In the final stage of broiling, broil briefly, just until the cheese is melted.
Is this a healthy recipe?
I believe it is. Mushrooms and tomatoes (including no-sugar tomato sauce) are very healthy. Cheese, for most healthy people, is pretty much harmless. As for the pepperoni, although not ideal, I use it here in a small quantity, so personally, I don’t worry about it. But if you wish, you could replace it with a healthier option such as sliced black olives.
How to serve portobello pizza
Portobello pizza is a wonderful snack, but it’s substantial enough to be an entree. When I serve it as an entree, I make two of them per person, and I serve them with the simplest and easiest of sides – microwave broccoli.

- Olive oil spray
- 1/4 cup marinara sauce, no added sugar (I use Rao's)
- 1/2 cup shredded Italian cheese blend (2 oz)
- 8 pepperoni slices (1/2 oz)
- Preheat your broiler on high. Set an oven rack in the middle of the oven. Line a baking sheet with foil for easy cleanup.
- Wipe the mushrooms clean with a damp paper towel. Gently twist off or the stem of each mushroom. Holding each mushroom in one hand, use a spoon to gently scrape out the gills.
- Spray the mushroom caps with olive oil spray on both sides, and sprinkle with kosher salt, black pepper and garlic powder. Broil until just tender, 4-5 minutes on each side.
- Remove the mushrooms from the oven, keeping the broiler on. Drain them, gill side down, on paper towels. Wipe the baking sheet dry, then return the mushrooms, gill side up, to the baking sheet.
- Fill each mushroom cap with half of the marinara sauce. Top with cheese and pepperoni (or your favorite toppings). Place back under the broiler, in the middle of the oven, just until cheese is melted, 2-3 minutes. Serve immediately.
