These Easy Portobello Mushroom Pizzas are a tasty low carb way to satisfy your pizza cravings. They’re so simple and ready in a flash!
Ingredients and substitutions
- Ground beef or sausage – for a healthier alternative, use ground turkey or ground chicken.
- Portobello mushrooms – you can try making these using another variety of mushroom like button or cremini, but they won’t be as big and will be more of an appetizer size than a meal.
- Pizza sauce – if you don’t have any pizza sauce, feel free to just use regular old tomato sauce.
- Mozzarella cheese – a ball of pizza mozzarella will give you the best level of meltiness. Swap out for another cheese of your choice, like Monterey Jack or cheddar.
- Green pepper – swap out for another veggie or pizza topping of your choice.
- Red onion – swap out for another veggie or pizza topping of your choice.
- Salt & pepper – to taste.
- Chili flakes – to taste. If you don’t like spice, leave these out altogether.
- Italian seasoning – to taste. Oregano, basil or thyme would also be good here.

Frequently Asked Questions
The key to making sure your portobello mushrooms don’t get soggy is leaving the right amount of flesh in the mushrooms. You want there to be about ¼ to ½ of an inch of mushroom left so your pizza portobello mushrooms don’t get thin and soggy.
Technically you can eat portobello mushroom gills, but they have a very distinct flavour. You’ll want to take them out before stuffing your mushrooms for this portobello pizza recipe, but you can definitely repurpose them and eat them on their own if you want.
There's no need to pre-cook the mushrooms. Just load in your toppings then cook the mushrooms in the oven for about 15 minutes. If you pre-cook the mushrooms, you risk them getting soggy and falling apart.
These pizza portobello mushrooms are pretty filling on their own, so you really don't need a side dish, but if you want something to serve on the side, you can't go wrong with Caprese quinoa salad, garlic bread or a nice kale salad.
There's no secret technique to scooping the flesh and gills out of the mushrooms – just use a spoon to gently scrape out the gills and flesh. Make sure you don't scoop out too much flesh, or the pizzas will fall apart.
Storing and reheating
You can store any leftover portobello mushroom pizza in the fridge for 3 to 4 days. Try to eat the leftovers as quickly as possible or the cheese will get all slimy! One serving includes two mushrooms, so there are four servings in this recipe.
To reheat, you can microwave the mushrooms for 1 to 2 minutes if you’re in a hurry, but I suggest reheating them in the oven for 10 to 15 minutes at 375° Fahrenheit for the best results.
Can you freeze portobello mushroom pizzas?
You can! Wrap the stuffed pizza portobello mushrooms in plastic wrap once cooled, then store them in a freezer-safe container for up to 3 months. You can reheat them from frozen in the oven for 25 to 30 minutes at 400° Fahrenheit. Easy-peasy!

Comments & Reviews
Waxza says
Absolutely delicious.
Carol L says
Clearly there was some sort of prize and thus all of the suggestions for the pizza sauce: I would make my “Poor Man’s Pizza”: french bread, pizza sauce mixed with olive oil and a few sliced green olives, topped with cheese. Those are officially the only ingredients, but I’d add a bit of meat, ground meat or chicken as well.
Thanks for the nice recipe. Keto approved as well. (or mostly!)
