Baked Stuffed Flat Mushrooms Recipe

Baked Stuffed Flat Mushrooms are so delicious you seriously have to make them!

Stuffed flat mushrooms on a baking tray ready for the ovenStuffed Flat Mushrooms – sounds good doesn’t it…..well let’s talk about Baked Stuffed Flat Mushrooms, sounds even better doesn’t it!! Similar to our Cream Cheese Jalapeno Poppers we are stuffing vegetables again! 

I think by now you guys know me well enough to know that when I try something, I need to try multiple different versions, flavour combinations and varieties so that I have nailed a recipe and an ingredient combo before I move on. I say this because I recently made Baked Stuffed Mushrooms (you can grab that recipe right here should you wish). They were AMAZING and tasted so good, so I had to do them again.

But, I couldn’t do the exact same ones as that would be boring and I wanted to make use the larger flat mushrooms as they are such a beautiful ingredient.

About the recipe:

So for this Stuffed Flat Mushroom recipe, I considered the following things:

  • A desire to use the large flat mushrooms and do them justice
  • Not make the exact same recipe as my earlier Baked Stuffed Mushroom Post
  • Add Gorgonzola (as it is delicious)
  • Use the same ingredients to make the texture for the top of the mushroom as it was not cheese based and had crunch

It didn’t take me long to work out how to do that.

Firstly, I want to show you guys the mushrooms, oiled and ready for stuffing…..they are good enough to eat after a little baking just like this, but remember how I said I wanted to do them justice….keep reading my friends.

Don’t they look beautiful, now let’s get to stuffing them full of good stuff.  So on a surface level, we are starting with the same combination that we know works oh so well with mushrooms and that’s bacon and shallots, but as we are wanting to take the flavours to another level we are adding pine nuts to the mix that we are going to bake in the oven for a little bit.

It is super easy to cook this part at this stage, as you literally do what I did and add the bacon, pine nuts and shallots to a lined baking tray, season with some salt and pepper, pour a wee bit of olive oil in there and then bake.

After this is done, you add these to a mixing bowl, with your parmesan cheese and whisked egg, now for the best part….we are going to add some chopped gorgonzola as it is one of the best flavoured cheeses in the world, then we stir to combine this to our already getting to good bacon mix.

Then we pack as much of this good stuff into our mushrooms as we can.

You should be rocking and rolling in your kitchen by now, so let’s mix some chopped up curly parsley (from your garden if you grow it) and panko breadcrumbs together to sprinkle all over the top of our mushrooms.

Things are going to be looking pretty good on your bench right about now………….like the pic below………..

On some level I think these Stuffed Flat Mushrooms look prettier before the final step of baking, but the taste after baking surpasses the visual appeal of the dish and you take your knife and fork and cut into the mushroom you will be LOVING the little party that is happening in your mouth. Well, it will be more like a refined soiree than a party, but I know you get what I am saying.

So my friends….without further ado, let’s get to reading that recipe so we can head to the shops for our ingredients…….

I’ve just shared it round my office via email as apparently I am in the minority and everyone loves mushrooms ?

Haha! That is awesome. I love mushrooms but I know everyone doesn’t so I won’t hold it against you.

I adore mushrooms but somehow I don’t make baked ones enough. Really like the use of pine nuts in that filling.

Adrianne October 15, 2018 - 9:00 am

Thanks Kavita! Yes, the pine nuts really work well! Cheers

I love mushrooms and these have got my mouth watering – I don’t have them as often as I should have when they are truly such a versatile ingredient. These baked stuffed mushrooms look absolutely delicious.

Adrianne October 15, 2018 - 11:49 am

Thanks Bintu! Yes, I love mushrooms and it is hard to remember to eat them often, but this is a good way to do it! Cheers 🙂
