  • 6 large portobello mushrooms cleaned, stems removed
  • 12 oz frozen spinach, thawed one bag, 10 - 12 oz.
  • 2 oz sun-dried tomatoes chopped
  • 8 oz. cream cheese softened
  • 3/4 cup finely shredded parmesan cheese divided
  • 1/2 cup shredded mozzarella cheese
  • 1 large garlic clove minced
  • Salt and freshly ground black pepper
  • 1/3 cup panko bread crumbs
  • 1 tsp dried oregano
  • 1 1/2 tsp olive oil


  • Preheat the oven to 400F and line a baking sheet with parchment paper.
  • Remove and discard the mushroom stems. Dry clean the mushrooms with the help of a brush or a clean paper towel to remove any dirt.
  • Chop the tomatoes and mince the garlic. Next, boil a small pot full of water. Add thawed spinach in a colander and set it over the sink.
  • As soon as the water boils, hold the colander firmly with a towel and carefully pour the boiling water over the spinach so it immediately wilts the leaves.
  • Once the leaves are wilted, immediately run under cold running water to refresh the leaves. Squeeze the spinach in your hands to remove the excess water.
  • Transfer the squeezed spinach to the chopping board and chop finely.
  • In a bowl mix together spinach, sun-dried tomatoes, cream cheese, half the parmesan cheese, mozzarella cheese, garlic, salt, and pepper.
  • In another bowl prepare the topping; combine, remaining half of the parmesan cheese, panko breadcrumbs, oregano, and olive oil. Stir until well combined.
  • For assembling, spray the mushrooms with cooking oil spray and place the caps onto the prepared baking sheet. Spoon the cream cheese filling into the mushroom caps.
  • Add a layer of topping on top and bake for 20-25 minutes until mushrooms are cooked through and the top is golden and crispy.
  • Serve warm and enjoy!


  • Use a preheated oven.
  • Panko breadcrumbs are better than fresh. No need to go all out and make your own breadcrumbs because panko actually works better than freshly made, they crisp up perfectly!
  • Don't forget to season the mushrooms. The stuffing will have seasoning but you want a pinch on the mushrooms too!
  • Be sure to squeeze the excess moisture out of the spinach, to avoid a watery stuffing!
  • If you want a spicy kick, try adding some red chili flakes to the breadcrumb topping.
  • For an extra pop of freshness, add some fresh parsley on top of each mushroom.
