In this post I provide you step by step recipe instructions so you’ll know exactly how to prepare and cook these wonderful mushroom appetizers and side dishes.

How to Make Stuffed Mushrooms

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

The best way to cook stuffed mushrooms is to bake them in an oven. You can choose a toaster oven or a standard oven.

Bake them at 350F-400F for at least 35-45 minutes. I give more detailed instructions below.

How to Make a Stuffed Mushroom

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

In this recipe you will need:

  • A pack of baby bella 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. 

Once the ingredients are all mixed and you’ve stuffed the mushrooms, you’ll bake them uncovered in the oven for about 35 minutes depending on the temperature.

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 pre-cook 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.   

How do I Make Stuffed Mushrooms?

Italian-style of course!

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

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

You can use brown baby mushrooms or white. Either ones 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.

I’ve made them both ways.

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.

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).  

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

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 remove mixture to a bowl.

Add Remaining Ingredients to the Stuffed Mushroom Mixture

Now, you’ll add the breadcrumbs, cheese, black pepper and parsley. Mix well.

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 for how 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” are delicious. I wouldn’t serve that to the guests, I eat them myself. 😁

How do you Cook Stuffed Mushrooms in the Oven

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

The length of time will vary based on the type of oven, such as convection or standard; as well as the temperature you bake it 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 accidently 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 done 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).

How Long to Bake Stuffed Mushrooms

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 are 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.

How Long to Bake Stuffed Mushrooms at 350

If you want to bake stuffed mushrooms at 350F, it will take 40-50 minutes to cook. However, keep in mind that that is assuming you have sauted 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 undercooked onions in the mixture!

You do not need to cover the onions while baking in the oven.

You will know when 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.

In case you are wondering, these are not finger foods. They will be too oily due to the drizzled oil and any mixture that leaked out during the stuffing.

How Long to Cook Stuffed Mushrooms at 400

If you’re looking to speed up the time a bit, it is good to cook your 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 at 400 (or 375Convection) for approximately 30-40 minutes. Check it to make sure they are easy to pierce and you’re ready! 

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.

Recipe Notes

If you’re preparing for more people, make sure to either buy enough mushrooms and 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.
