Preparing The Mushroom

Begin by gently washing the dirty mushroom with cool water and then wiping it with a soft paper towel or cloth. If you feel the mushroom is still dirty, you can use a soft scrub brush and lightly scrub the outside of it too. Although it isn’t necessary to remove the stem, it can sometimes be a bit woody tasting, so it is good practice to take it out. Using a spoon, gently scrape the gills and base of the stem until the mushroom is cleaned out. Be careful not to remove all of the fleshy parts though. Now your mushroom is ready to be stuffed.

Ingredients

Serves: 4

  • 4 large portobello mushrooms wiped with a damp paper towel
  • 1 lb of ground turkey or chicken.
  • 2 tablespoons extra-virgin olive oil plus more for coating the mushrooms
  • 1 large sweet red onion, diced.
  • 1 red bell pepper, diced.
  • 1 – 2 fresh garlic cloves, minced.
  • 1 pinch of dried oregano. 
  • dash of crushed red pepper flakes.
  • kosher salt & freshly ground black pepper to taste.
  • 1/4 C goat cheese, chunked.
  • 1 egg.
  • 1/4 C mozzarella cheese.

Directions

  1. First thing, preheat your oven or smoker to 375 degrees. Spray or line a baking sheet with parchment paper.
  2. Clean your portobello caps lightly using a soft scrub brush or cool water.
  3. Let dry and then using a small spoon, gently scoop the gills out of the inside of the mushroom. With a small knife, remove the mushroom stem.
  1. Rub each of the portobello mushroom caps with a bit of olive oil and set them on the prepared baking sheet, stalk side up.
  2. In a medium bowl, mix together ground meat, chopped onion, red pepper, garlic, oregano, red pepper flake and salt & pepper thoroughly.
  3. Add the egg to the mixture. 
  1. Gently roll in the goat cheese making sure to not break all the chunks down.
  2. Spread the mixture out evenly in the pan and then using a spoon, slice through like a pie to divide equally. Stuff each mushroom with a quarter of the mixture.
  3. Bake mushrooms in the oven or on the grill for about 35 to 40 minutes.
  4. Top each mushroom with about 1 tablespoon of the mozzarella and continue baking for another 10 to 12 minutes, or until the cheese is just beginning to get golden on top.

Tips and Tricks for Making Stuffed Portobello Mushrooms

  • Be sure to remove the stalks and gills from the portobello. The mushroom stems can taste quite woody when cooked and the dark gills can leave the mixture looking muddy or brown.
  • Feel free to adjust the recipe by adding your favorite types of seasonings or fresh herbs. Substitute thyme or fresh parsley for a slightly different variation of flavor.
  • Try switching up the types of cheese. Feta has a wonderful taste when combined with the ingredients for this recipe or perhaps you top the mushrooms off with some parmesan cheese. I always recommend trying the recipe the first time as written but the next time, let your taste buds decide.

Storing Stuffed Mushrooms

Stuffed Portobello mushrooms are one of my favorite meals to make extras for leftovers because they taste just as good when you reheat them. To store them, simply keep them in an airtight container in the refrigerator for up to 5 days.

 I wouldn’t recommend freezing them once they have been fully cooked but you can freeze them ahead of time in a ziplock bag or airtight container for up to 3 months.

Frequently Asked Questions

Can you eat the inside of a portobello mushroom?

The mushroom gills are completely edible, however, they do tend to get in the way when you are stuffing your mushrooms. The gills can also turn your food brown and discolored so it is best to remove them.

How do you know when portobellos are cooked?

The cooking time for a portobello mushroom is completely dependent on the size of the mushroom and the temperature they are being cooked at. A good test to know if the portobello mushroom is cooked is to press on the center and if the mushroom appears to be soft and juicy, then it is ready
