I know a lot of people are not a fan of mushrooms, but mushrooms are great for you and they are full of vitamins. I, personally, love them and I cook with mushrooms a lot. They’re very versatile and are perfect for stuffing.
Stuffed Mushrooms
I love stuffing mushrooms, and I have a couple other recipes on the blog, like these veggie stuffed mushrooms or these pizza stuffed mushrooms.
Mushrooms are very versatile and there are lots of ways to use them. I use them in pasta, stir fries, pies, or roast them. My favorite way to have them though, is to stuff them, because you can literally stuff them with anything and everything.
Ingredient Notes
- Portobello mushrooms – Portobello mushrooms come in different sizes. Not only can you use large portobello mushrooms, you can also use baby portobellos. Having said that, regular white mushrooms or cremini mushrooms can also be stuffed, so use your favorite. The only thing to keep in mind is that the smaller the mushrooms are the more you can stuff.
- Cheese – In this recipe, I used a combination of goat cheese and mozzarella cheese, but feel free to use your favorites.
- Veggies – I used a combination of spinach, bell peppers and tomatoes. You can use other veggies as well.
- Onion and Garlic – I love using these ingredients to enhance the flavor of the stuffing.
- Breadcrumbs – Necessary to bind the veggies a bit. You can use your favorite breadcrumbs, Italian or Panko.
- Hot Sauce – This is an optional ingredients, and only add it if you want your stuffed mushrooms to have a bit of a kick.
How To Make Portobello Stuffed Mushrooms
- Prep the oven: Preheat oven to 400°F.
- Prep the mushrooms: Carefully remove stems from mushrooms, reserve and chop the stems for the stuffing. Place the mushrooms stem side down onto a baking pan. Bake for 10 to 15 minutes until the water leaks out of them. Remove from the oven and using paper towels soak up excess water. Set aside.
- Make the filling: In a skillet, heat the olive oil over medium heat. Add the chopped onion and garlic and saute for a couple minutes until the onion is translucent. Add the green pepper and spinach to the skillet and cook for a couple more minutes, until the spinach wilts. Stir in the tomatoes, goat cheese, salt, pepper, mushrooms stems, hot sauce and breadcrumbs. Cook for an additional 2 minutes.
- Stuff the mushrooms: Stuff the mushrooms with the mixture equally. Top with mozzarella cheese. If using smaller mushrooms you should have enough mixture for about 8 mushrooms.
- Bake: Bake for 10 minutes or until the cheese melts.

Great recipe! Delicious, healthy, and totally flexible with whatever veggies you have on hand too! I made it as written but have also varied it by adding in sliced asparagus, red bell pepper, feta cheese, and topping with cheddar cheese. The addition of hot sauce does not make it “hot” (at least not to me) but adds a TON of flavor. Don’t leave it out– I had tried the mixture before the hot sauce and then after and BIG difference!
So. Good.
Jo.
thanks for sharing, these were easy to make and delicious.
After freezing, do you defrost before cooking or cook from freezing?
No, you don’t have to thaw them out, you can put them straight in the oven, they may require a couple extra minutes.
recipe sounds delicious and easy to make. looking forward to making tonight
I haven’t made these yet but I’m planning to tonight.. I just wanted to check out of curiosity (for future reference), when you say it’s best to freeze before baking, do you only mean the final bake? Is it still best to do the pre-bake in the prep step before freezing? Sorry if this is a silly question ^_^;
Not a silly question, but yeah pre-bake them and then freeze them stuffed.
After putting them stem-side down in the oven for 10ish minutes, my mushrooms flattened into disks. There was no room for stuffing so I carefully layered it on top like a pizza… is there a way to prevent this mushroom flattening?
That shouldn’t have really happened. You can try putting them stem-side up and then if there’s any liquid inside the mushroom just use a paper towel to soak it up.
Same happened to me! Still good but shrunk my mushrooms quite a bit.
I ran into the same issue. My solution was to form the caps back to shape with an inverted tiny bowl or custard dish by laying them on top of it as they cooled.
One of our favorite meatless meals, we love this!!
Can shredded chicken be added to this?
Sure!
I made these last night for dinner using large mushrooms for a main dish meatless dinner. They were absolutely delicious and my husband said that I can make them again anytime!!
We love to see everyone happy with our recipes. So glad you two enjoyed them!
This is a tasty and easy recipe which is quick to prepare ((40 minutes start to finish as stated). I always remove portobello gills before baking. They are dark and can make the filling unappealing! Have made this several times and it’s my go-to stuffed mushroom recipe. Thanks Jo!!
We are so glad you liked them!
I really liked how easy it was to make. I added some chopped artificial crab meat and a small amount of chopped shrimp. I also added old bay seasoning to give the seafood some kick.
We all loved these!!! Easy and delicious!
Loved this!
Loved the mushrooms, I didn’t use peppers I run from them. I added soaked walnuts, nutritional yeast for that cheesy flavour ( now it’s vegetarian ). So good thanks for the inspiration! So yummy.
