Baked Portobello Mushroom Recipe Italian Style

Everyone loves a good stuffed mushroom dish, but we’ve all had the usual breadcrumb, garlic, and parsley recipe.

I’ve got nothing against that one, but sometimes a change is in order.  This baked portobello mushroom recipe delivers the change you need.

Balsamic bruschetta with mozzarella – love it.  Stuffed into some portobellos – even better!

Balsamic vinegar with tomatoes is so fresh and tangy – the flavor goes amazingly well with the portobellos.

The fresh mozzarella broiled on top just makes it one level better.  Honestly, even without the cheese it’s good, so this could easily be adapted to a vegan dish.

They look so nice too.

One per person is plenty.  No more need to stuff 50 mushrooms – what a bonus!

These are a great appetizer to pair with a big pot of Sunday Sauce with Pasta and Meatballs.

Fresh mozzarella, cherry tomatoes and 1 red onion.

Baked Portobello Mushrooms With Bruschetta And Mozzarella Process:

Portobello mushrooms on cutting board.

The first step is to clean the mushrooms.  How do you clean a mushroom?  Use a paper towel to gently wipe off any dirt.  Mushrooms are grown in dirt – clean dirt – but dirt nonetheless.  Use a dry towel.

Wetting them will only hurt the roasting process, since the mushrooms act like a sponge.  Whenever any vegetable is roasted it’s best done dry, so the oven doesn’t have to work at evaporating the water.

The longer the water takes to evaporate, the longer it will be before the roasting process gets on its way, so try to keep them nice and dry.

Next remove all the gills and stems of the portobello mushrooms with a small metal spoon.  Try to keep the mushroom intact.  As you can see I managed to screw one up.  It’s all good – it’s cooking and nothing is ever perfect.

Next, place the cleaned mushrooms on a sheet pan.  Season them with a couple tablespoons of olive oil and a 1/4 tsp of kosher salt and a 1/8 tsp of black pepper.

Bake the portobellos for 10 minutes at 375° on the middle oven rack.

Remove them from oven and pat dry to remove any water that was released.

Chopped tomatoes and red onions.

Chop up 1 pint of cherry tomatoes and a 1/2 cup of red onion.  Mince 3 cloves of garlic.

Parsley for the baked portobello mushrooms.

Chop roughly a 1/4 cup of parsley.

Chopped tomatoes and red onions in a bowl.

Combine the tomato, red onion, and garlic into a bowl.  Add 1/4 tsp of salt and 1/8 tsp of pepper.  Add 2 Tbsp of balsamic vinegar and 2 Tbsp of olive oil and mix the bruschetta together.

Stuff the bruschetta into the portobellos.

Portobellos topped with fresh mozzarella.

Add the fresh mozzarella slices onto the stuffed portobellos and add a drizzle of olive oil to each one.  Bake for 5 minutes more.

After 5 minutes remove pan and move oven rack to highest level.  Turn broiler on high.

Return mushrooms to oven and watch carefully as they broil.

This is after 3 minutes of broiling on the top rack of my oven.  Your oven will be different.  The objective is to get a nice bubbly cheese mixture.

Top the portobellos with fresh parsley.  A healthy drizzle of extra virgin olive oil and a little more balsamic wouldn’t hurt either.

  • Clean portobello mushrooms with a dry paper towel to remove dirt.  Remove gills and stem of each mushroom with a metal spoon.  Place mushrooms on baking sheet.
  • Season each mushroom with half the olive oil, salt, and pepper and place mushroom tray in oven to bake.  Set timer for 10 minutes.
  • Slice fresh mozzarella into 1/4" pieces.  Set aside.
  • Cut cherry tomatoes into quarters.  Chop a 1/2 cup of red onion.  Mince 3 cloves of garlic.  
  • Combine the tomatoes, onion, and garlic in a mixing bowl.  Add 2 Tbsp of olive oil and 2 Tbsp of balsamic vinegar.  Add remaining salt and pepper to bowl and stir it all together. 
  • Remove mushrooms at ten minute mark and dry off the excess moisture with a paper towel.  Evenly distribute the bruschetta to each mushroom and top with one slice of the fresh mozzarella.

    I had these at a friends house, so had to search for the recipe. I found Jame’s, and it looked terrific. I made this on the BBQ, so simply mixed the mozzarella into the bruschetta. Wonderfully delicious. Thanks James.
