Ingredients

Garlic butter

  • 2 tablespoons butter
  • 2 cloves garlic , crushed
  • 1 tablespoon freshly chopped parsley

Mushrooms:

  • 5-6 large Portobello Mushrooms , stem removed, washed and dried thoroughly with a paper towel
  • 5-6 fresh mozzarella cheese balls , sliced thinly
  • 1 cup grape (or cherry) tomatoes, sliced thinly
  • fresh basil , shredded to garnish

Balsamic Glaze: (or you can use store bought, or this recipe)

  • 1/4 cup balsamic vinegar
  • 2 teaspoons brown sugar (OPTIONAL)

Instructions

  • Preheat oven to grill/broil settings on high heat. Arrange oven shelf to the middle of your oven.
  • Combine all of the Garlic Butter ingredients together in a small saucepan (or microwave safe bowl), and melt until garlic is fragrant. Brush the bottoms of each mushroom and place them, buttered side down, on a baking tray.
  • Flip and brush any remaining garlic over the insides of each cap. Fill each mushroom with the mozzarella slices and tomatoes, and grill/broil until cheese has melted and golden in colour (about 8 minutes).
  • To serve, top with the basil, drizzle with the balsamic glaze and sprinkle with salt to taste.

For the Balsamic Glaze:

  • (If making from scratch, prepare while mushrooms are in the oven.) Combine sugar (if using) and vinegar in a small saucepan over high heat and bring to the boil. Reduce heat to low; allow to simmer for 5-8 minutes or until mixture has thickened and reduced to a glaze. (If not using sugar, allow to reduce for 12-15 minutes on low heat).

Notes

*To dry portobellos, make sure you use a dry sheet pot paper towel per mushroom, and lightly press sheet into each mushroom to gently squeeze out the excess liquid. If this step is not done thoroughly, the portobellos will release a lot of liquid during cook time.
