Servings: 12 Mushrooms
Calories: 61kcal

Ingredients

  • 16 medium white mushrooms about 1lb
  • 3 cups fresh spinach
  • ¼ cup parmesan cheese + 2 tbsp grated
  • 3 cloves garlic
  • 2 tablespoons fresh parsley chopped
  • 4 oz cream cheese
  • 1 tablespoon olive oil
  • ½ teaspoon salt
  • ¼ teaspoon ground pepper

Instructions

  • Wash mushrooms and remove their stems. Chop stems into small pieces.
  • Add the olive oil to a skillet and heat over medium heat. Add thinly sliced fresh garlic and chopped mushroom stems. Stir until golden and fragrant. Be careful not to burn the garlic.
  • Add fresh spinach to the pan.
  • Stir the spinach, garlic, and mushroom stems until the spinach is well sautéed. Season with salt and pepper.
  • Add the cream cheese (soften or chop it into chunks first so it mixes evenly). Combine ingredients and remove from heat.
  • Add chopped parsley and ¼ cup grated parmesan cheese. Stir to combine.
  • Fill each mushroom cup with around ½ tbsp of the creamy spinach mix. The amount will vary based on the size of the mushroom. Sprinkle extra parmesan on the top of each mushroom.
  • Place the mushrooms on a non-stick baking tray and bake them for 12-15 minutes at 375F. The mushrooms will be fork-tender when ready.
  • Remove from the oven and drain any excess liquid from the tray before serving.

Notes

Recipe Variations and Substitutions
  • Add Nuts: Stir chopped almonds or nuts of your choice through the spinach mix for extra crunch. Almonds or pistachios work best with these flavors.
  • Make Them Crispy: Sprinkle breadcrumbs or panko over the top of the mushrooms halfway through the cooking process (so it doesn’t burn) for a crispy finish.
  • Herb Swaps: Replace parsley with fresh herbs like basil, thyme, or dill for a different aromatic twist.
  • Add Spice: Introduce a little heat by adding red pepper flakes or a dash of cayenne pepper to the filling.
  • Mushrooms: If you can’t get white mushrooms, any mushroom that can hold the spinach stuffing well will work, such as cremini brown mushrooms or small portobello.
Expert Tips
  • Choose the Right Mushrooms: Opt for firm, fresh, and roughly the same size for consistent cooking and presentation. 
  • Serving Temperature: You can serve these stuffed mushrooms either hot or cold. 
  • Make Ahead: You can prepare these mushrooms up to a day in advance. Fill the mushrooms and keep them covered in the fridge until baking time.
