About this Recipe

This is an Italian recipe which is from my mother, which is always a winner.

The beauty of this recipe is that it doesn’t have a strong mushroom flavor due to the other ingredients, so even non-mushroom fans will be impressed.

Making stuffed mushrooms is very easy. I use baby mushrooms, although you can also use other varieties such as portabella which would also make a wonderful choice.

Once the ingredients are all mixed and you’ve stuffed the mushrooms, the best way to cook stuffed mushrooms is to bake them in an oven. You can choose a toaster oven or a standard oven.

I give more detailed instructions below and tips for when you’re in a hurry!

Ingredients Needed

The first thing you’ll need to know before you start making your delicious stuffed mushrooms is what ingredients you need to use.

In this recipe you will need:

  • A pack of baby mushrooms
  • Onion
  • Grated Italian cheese like Parmesan (or my favorite Romano)
  • Breadcrumbs
  • Parsley
  • Salt/Pepper
  • Olive oil & Butter

And to make it even easier, if you have seasoned breadcrumbs you can skip the additional Italian herbs.  You can learn how to make your own breadcrumbs here. 

PRO TIP: You can use brown baby mushrooms or white. Either one taste great and there is no difference in how you cook them in the oven.

The butter and olive oil mixture acts as the binder to help the mixture stick together. If you prefer to not use the butter, you can most certainly use just olive oil.

Instructions

Italian stuffed mushrooms

Step 1. Clean the Mushrooms

The first step to making the stuffed mushrooms is to clean them!

Use a damp cloth or paper towel and rub any loose dirt off the mushrooms. You can run them under some water but you want to make sure to pat-dry each one since mushrooms contain so much moisture to begin with.

Step 2. Remove and Chop the Mushroom Stems

Yes, you want to use the stems! Use the stems of the mushrooms as explained in my cooking video (see below or on YouTube).  

clean and prep the mushrooms

Simply remove the stem by gently moving it back and forth. Once removed, cut off the hard end of the stem (the part that was not connected to the mushroom cap).

Once the stems removed, dice them finely and place in a medium bowl. Don’t worry if you’re concerned they will be tough, they won’t be. We’ll be sautéing them in the butter/olive oil mixture.

saute the stems onions and garlic
Cook down until the onions are translucent and most of the water content is removed.

Step 3. Saute and cook down.

Next, saute the mushroom stems along with the diced onion in a pan of olive oil and butter over medium heat.

Once the onions are translucent and tender set aside or add to the bowl that has the stuffing.

Step 4. Add Remaining Ingredients to the Stuffed Mushroom Mixture

Now, you’ll mix the breadcrumbs, cheese, black pepper and parsley in a bowl. Mix well.

Step 5. Stuff the mushrooms!

Once the mixture is ready, stuff the mushrooms using a small spoon (or your fingers) making sure to try your best at not tearing the sides of the mushroom.

This is the best way to stuff a mushroom. Repeat this process for each mushroom.

Any extra mixture left over after stuffing your mushrooms I always just pile on top of the mushrooms and let the filling spill over into the baking pan.

Drizzle a small amount of olive oil on the top of each mushroom so the breadcrumbs will get crispy as they cook in the oven.

These cooked “fixings” that have spilled over on the baking pan are delicious. I wouldn’t serve them to the guests, I eat them myself. 😁

About Baking Times

You will want to cook the stuffed mushrooms in an oven safe dish, uncovered. Place on the medium rack. The oven should be preheated.

bake the stuffed mushrooms

The length of time will vary based on the type of oven, such as convection or standard, as well as the temperature you bake them at. What I love about making this recipe is that the temperature is very flexible. It is very hard to burn stuffed mushrooms.

I’ve accidentally left them in too long but they still tasted amazing as the stuffing was simply more crispy.

Remember, baby bella mushrooms have a high moisture content. However, the typical temperature is either 350F or 400F.

The higher the temperature the shorter the cooking time. I cook mine at 375F, however I’ve also baked them at 350 and 400F. If I’m in a hurry or running a little short on time, I will cook the stuffed mushrooms in a convection oven at 375 (which equates to 400F).

PRO TIP: You do not need to cover the mushrooms while baking in the oven. You will know they are done when you can easily pierce a mushroom using a fork. It will not be mushy so don’t wait till it’s like that – you want them firm but easy to cut with a fork.

Baking at 350F

If you want to bake stuffed mushrooms at 350F, it will take 40-50 minutes to cook. However, keep in mind that is assuming you have already sauteed your onions as described in my recipe.

If the onions are uncooked it may take longer and the worst thing you can do is serve under cooked onions in the mixture!

Baking at 400F

If you’re looking to speed up the time a bit, it is good to cook your Italian stuffed mushrooms at 400F in the oven. If you choose to use a convection oven, set the temperature to 375 to accommodate for the 25 degree difference achieved from the convention fan.

Bake for approximately 30-40 minutes. Check to make sure they are easy to pierce and you’re ready! 

Why am I not Including Sausage

Sausage is definitely a popular ingredient in stuffed mushroom recipes, however I do not use sausage. If you want to use sausage please precook the sausage, drain the excess fat, and add it to the bread mixture/filling. 

This recipe is perfect for vegetarians, however vegans will need to use an alternative for the cheese and omit the butter.

If you’re looking for gluten-free breadcrumbs, try taking some gluten-free cereal and grind it to mimic the texture of breadcrumbs.   

Reheating Stuffed Mushrooms

Stuffed mushrooms always taste better warm than cold, so it is always a good idea to reheat your mushrooms in the oven or toaster oven for about 10 minutes until warmed through.

If you plan on making these ahead of time and will need to reheat the mushrooms, I’d recommend cutting back the time by 15 minutes and then reheat at 400F for 15 minutes or until they are done.

Situations where this would occur would be for parties or preparing the mushrooms ahead of time. Make sure that if you are taking the mushrooms to a party that you will have access to the oven when you get there.

I do not recommend reheating mushrooms in the microwave.

  • 1/3 cup breadcrumbs

  • Remove stems and chop them up into small pieces.
  • Heat the olive oil and butter over the stove on medium heat in a frying pan.
  • Dice the onion into small pieces.
  • Add the mushroom stems and onion into the melted butter/olive oil.
  • Saute until tender and translucent about 5-10 minutes.  Don't let them burn. 
  • Meanwhile mix together the breadcrumbs, cheese, herbs and pepper in a bowl.
  • When the onions and stems are done, add them into the breadcrumbs.
  • Drizzle some olive oil into the mixture and mix well.
  • Stuff the mushrooms well, allowing the excess breadcrumb mixture to spill over, that's totally fine.

Notes

If you’re preparing for more people, make sure to either buy enough mushrooms or you can also look for packages that have smaller mushrooms to allow for a greater quantity of individual mushrooms.  This makes a big difference when preparing for appetizers/finger food.
