Ingredients

Scale

Mushrooms

  • 16 oz portobello mushrooms

Filling

  • 8 oz cream cheese, softened
  • 1/4 cup powdered parmesan cheese
  • 1/3 cup sour cream
  • 1/4 teaspoon oregano
  • 1/2 teaspoon garlic powder
  • 1/4 teaspoon onion powder
  • 1/4 teaspoon salt
  • 1/4 teaspoon pepper
  • 1/4 teaspoon basil

Garnish

  • Fresh parsley, chopped, for garnish

Instructions

  1. Preheat Oven: Set your oven to 375°F (190°C) to preheat, ensuring it’s ready for baking the mushrooms.
  2. Prepare Mushrooms: Rinse the portobello mushrooms gently under cold water and pat dry. Remove the stems carefully to create space for the filling.
  3. Arrange Mushrooms: Place the mushroom caps upside down (gill side up) in a baking dish, ready to be stuffed.
  4. Make Filling: In a mixing bowl, combine the softened cream cheese, powdered parmesan, sour cream, oregano, garlic powder, onion powder, salt, pepper, and basil. Beat the mixture thoroughly until smooth and well blended.
  5. Stuff Mushrooms: Using a spoon, fill each mushroom cap generously with the prepared cheese and herb mixture.
  6. Bake: Place the stuffed mushrooms in the preheated oven and bake for 20 to 25 minutes, or until the tops are nicely browned and the filling is heated through.
  7. Garnish and Serve: Remove from oven and sprinkle fresh chopped parsley over the mushrooms before serving to add a pop of color and freshness.

Notes

  • Be sure not to overfill the mushrooms to avoid spillage during baking.
  • You can swap sour cream for Greek yogurt for a tangier twist.
  • To make this recipe gluten-free, verify that all seasoning powders are gluten-free.
  • For a vegan version, substitute cream cheese and sour cream with plant-based alternatives.
