Description

These delicious stuffed mushrooms are a perfect appetizer or side dish, featuring tender cremini mushrooms filled with a savory mixture of roasted red peppers, garlic, spinach, and creamy ricotta cheese, topped with parmesan and baked to perfection with a golden, crispy finish.


Ingredients

Mushrooms

  • 2 pounds cremini or white button mushrooms
  • 2 tablespoons extra-virgin olive oil
  • 1 teaspoon salt
  • 1/2 teaspoon black pepper

Filling

  • 1/2 packed cup roasted red peppers, finely chopped
  • 1/2 cup finely chopped yellow onion
  • 3 large garlic cloves, minced
  • 2 teaspoons Italian seasoning
  • 2 packed cups baby spinach, finely chopped
  • 1/2 cup whole milk ricotta cheese
  • 1/2 cup parmesan cheese
  • Reserved mushroom stems, finely chopped (from the 2 pounds mushrooms)
  • 2 tablespoons finely minced parsley, for garnish


Instructions

  1. Preheat Oven: Preheat your oven to 375°F to ensure it reaches the perfect temperature for baking the stuffed mushrooms.
  2. Prepare Mushrooms: Wash the mushrooms and carefully remove the stems to create a cavity for the filling. If needed, use a small spoon to scrape out the stems. Keep the stems aside to chop and use in the filling.
  3. Season Mushrooms: Place the mushroom caps on a baking sheet. Drizzle with 1 tablespoon of olive oil, then sprinkle with 1/2 teaspoon salt and 1/2 teaspoon black pepper. Toss gently to coat all caps evenly, then arrange them in a single layer, cavity side up.
  4. Cook Filling Base: Heat 1 tablespoon olive oil in a medium skillet over medium heat. Add the finely chopped mushroom stems, roasted red peppers, onion, garlic, Italian seasoning, and remaining 1/2 teaspoon salt. Cook, stirring occasionally, for about 5 minutes until the vegetables soften.
  5. Add Spinach: Stir in the chopped baby spinach and cook for an additional 2 minutes until wilted and well combined with the other vegetables.
  6. Combine Filling: Transfer the vegetable mixture to a medium bowl. Add the ricotta cheese and stir thoroughly to blend all ingredients into a creamy filling.
  7. Stuff Mushrooms: Using a small spoon, fill each mushroom cap generously with the prepared filling. Sprinkle parmesan cheese evenly on top of each stuffed mushroom.
  8. Bake: Place the baking sheet in the preheated oven and bake for 20 minutes, or until mushrooms are tender and the cheese has melted.
  9. Broil for Crispiness: Switch the oven to broil and broil the mushrooms for 2 to 3 minutes to achieve a golden, crispy parmesan cheese crust. Keep a close watch to avoid burning.
  10. Garnish and Serve: Remove from oven and sprinkle with finely minced parsley. Serve the stuffed mushrooms warm as a tasty appetizer or side dish.

Notes

  • Make sure to not overcrowd the baking sheet to allow even cooking.
  • You can substitute baby spinach with kale or Swiss chard if preferred.
  • For a vegan version, replace ricotta and parmesan with plant-based cheeses.
  • Serve immediately for best texture and flavor; leftovers can be refrigerated and reheated gently.
  • If mushrooms release excess water during baking, drain it for better texture.
