  • 4 portobello mushroom caps, washed, stems and insides scraped out
  • 2 tbsp olive oil
  • 1 cup baby spinach, chopped
  • 2 tbsp grated parmesan cheese
  • 1 tsp minced garlic, 1-2 cloves
  • 1/4 cup cream cheese, room temperature
  • 1/4 cup plain, greek yogurt
  • 1/4 tsp onion powder
  • 1/4 tsp salt
  • 1/2 cup pizza sauce, your favorite sauce or marinara sauce
  • 1.5 cups reduced-fat shredded mozzarella cheese
  • 30 mini pepperonis

Garnishment (optional):

  • Freshly chopped parsley
  • Grated parmesan cheese


  • Preheat oven to 350 degrees F.
  • Place a medium pan over medium heat and spray with nonstick cooking spray. Once heated, add the chopped spinach and cook until wilted. Remove from heat to cool.
  • Once the insides of the mushrooms caps are removed, brush both sides (as well as the insides) with olive oil and place onto a baking sheet.
  • Place the mushrooms into the oven and allow to bake 8-10 minutes. Remove and drain of any excess moisture. I used a few paper towels to soak up any drainage on the pan, as well as inside the mushrooms. The more moisture you remove - the better.
  • To a small mixing bowl, combine the sautéed spinach, minced garlic, parmesan cheese, cream cheese, greek yogurt, onion powder, and salt. Mix to throughly combine making sure to remove any chunks.
  • Scoop the spinach dip mixture into each cap, spreading evenly using the back of the spoon. Top each with 2 tablespoons of your favorite pizza or marinara sauce, followed by the mozzarella cheese and mini pepperonis. 
  • Place back into the oven to bake for an additional 8-10 minutes, or until the cheese has melted. To brown the cheese a bit, turn the oven to broil on LOW for 3-4 minutes. 
  • Remove, garnish with basil and parmesan cheese, and enjoy!
