20 large white button mushrooms or cremini mushrooms
2 tablespoons olive oil, divided
2 cloves garlic, minced
5 ounces fresh baby spinach, finely chopped
4 ounces cream cheese, softened to room temperature
1/4 cup grated Parmesan cheese
1/4 cup Panko breadcrumbs
1/4 teaspoon salt
1/4 teaspoon black pepper
1/8 teaspoon red pepper flakes (optional for heat)
Fresh parsley for garnish
Instructions
Preheat your oven to 375°F (190°C). Clean the mushrooms using a damp paper towel to remove any dirt. Gently pop the stems out of the mushroom caps. Finely chop about half of the mushroom stems and set them aside; you can discard or compost the remaining stems.
Heat one tablespoon of olive oil in a large skillet over medium heat. Add the chopped mushroom stems and cook for about 3-4 minutes until they soften. Stir in the minced garlic and cook for another 30 seconds until fragrant.
Add the chopped spinach to the skillet. Cook, stirring constantly, for 2 minutes or until the spinach has completely wilted. Remove the pan from the heat and drain any excess liquid to ensure your filling isn’t watery.
In a medium mixing bowl, combine the cooked spinach mixture, softened cream cheese, Parmesan cheese, salt, pepper, and red pepper flakes. Stir until the mixture is smooth and well combined.
Brush the outside of the mushroom caps with the remaining olive oil and place them open-side up on a baking sheet. Use a small spoon or a piping bag to fill each cap generously with the spinach mixture. Sprinkle the tops with Panko breadcrumbs.
Place the baking sheet in the oven and bake for 18-20 minutes. The mushrooms should be tender, and the breadcrumbs should be golden brown. Garnish with fresh parsley before serving warm.
