Stuffed Portobello Mushrooms

Ingredients

4 large Portobello mushroom caps, cleaned and stems removed
2 tablespoons olive oil
1/2 cup breadcrumbs (preferably panko for extra crunch)
1/2 cup shredded mozzarella cheese (or your favorite cheese)
1/4 cup grated Parmesan cheese
2 tablespoons fresh parsley, chopped (or basil)
2 cloves garlic, minced
1/4 cup cream cheese (optional, for extra creaminess)
1 teaspoon dried oregano
Salt and pepper, to taste
1 tablespoon balsamic vinegar (optional, for drizzling)

(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)

Directions

Prepare the mushrooms: Preheat your oven to 375°F (190°C). Clean the Portobello mushrooms by gently wiping them with a damp cloth. Remove the stems and carefully scoop out the gills with a spoon to create space for the filling.
Prepare the filling: In a medium bowl, combine the breadcrumbs, mozzarella cheese, Parmesan cheese, parsley, garlic, and oregano. Stir in the cream cheese if using, then season with salt and pepper to taste. Mix until everything is well combined. If the mixture feels too dry, add a splash of olive oil or a little water to moisten.
Stuff the mushrooms: Place the mushroom caps on a baking sheet, gill-side up. Spoon the breadcrumb mixture into each mushroom cap, pressing it down gently to fill the cavity. Drizzle a little olive oil over the top of each stuffed mushroom for added richness.
Bake: Bake the stuffed mushrooms in the preheated oven for 20-25 minutes, or until the mushrooms are tender and the stuffing is golden and crispy on top.
Serve: Once baked, drizzle with balsamic vinegar for a tangy finish, if desired. Garnish with extra parsley or basil and serve hot.

FAQs

1. Can I use baby portobello mushrooms instead of large ones?

Yes, you can prepare the stuffing mixture ahead of time and store it in the fridge for up to a day before stuffing the mushrooms and baking.
