These Easy Pizza Portobello Stuffed Mushrooms 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.

What to serve with stuffed mushrooms
Since these pizza stuffed mushrooms are low carb, you have the flexibility to add any type of side dish you'd like and the calorie count will still probably remain pretty low.
Now's your chance to add a fun side like garlic bread, but you could also go the healthy route and serve these mushrooms with a side salad. They are pretty filling on their own. so you really don't need a side dish, but it's nice to know you have options!
Frequently Asked Questions
Yes, in order to make these stuffed mushrooms, you’ll need to scrape out the flesh. Scrape them out gently with a spoon so you don’t crack or split the mushroom shell.
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 it doesn’t get thin and soggy.
Technically you can eat the gills but they have a very distinct flavour. You want to take them out before stuffing your mushrooms but you can definitely repurpose them and eat them on their own if you want.
Storing and reheating
You can store leftover stuffed portobellos in the fridge for 3 to 4 days. You do want to try to eat them as quickly as possible or the cheese will get all slimy. I don't think this will be an issue for you as these mushrooms are BOMB and you'll likely eat them up right away! FYI – one serving is two mushrooms, so there are four servings in this recipe.
To reheat, you can microwave for a minute or two if you’re in a hurry, but I suggested reheating them in the oven for 10-15 minutes at 375° Fahrenheit for the best results.
Can you freeze stuffed mushrooms?
You can! Wrap the stuffed 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 25-30 minutes at 400° Fahrenheit. Easy-peasy!

Do you have a recommendation for scooping the flesh out of the mushrooms? I struggled with it so much and the tops tore into several pieces since the flesh was so rubbery my spoon wouldn’t cut through it. I ended up just laying the pieces of mushroom top into a pan as a single sheet and doing 1 larger pizza.

It honestly just takes practice and a gentle hand. Grabbing the mushroom with your whole hand then gently scraping thin layers off the top once you’ve cut the stems out are your best bet. I’m sorry you had trouble!
