Ingredients

Instructions

  1. Step 1: Preheat oven to 400°F. Slice zucchini lengthwise in half and scoop out seeds with a spoon, creating hollow boats (reserve seeds for other use). Brush cut sides with 1/2 tbsp olive oil and place cut-side down on a parchment-lined baking sheet. Bake for 10 minutes until slightly softened.
  2. Step 2: Heat remaining 1/2 tbsp olive oil in a skillet over medium heat. Add mushrooms and cook for 8 minutes until golden and liquid has evaporated. Stir in minced garlic and cook for 1 minute until fragrant.
  3. Step 3: Remove zucchini from oven, flip to cut-side up, and fill with mushroom mixture. Sprinkle with 2 tbsp Parmesan, parsley, salt, and pepper. Return to oven and bake for 12 minutes until cheese is melted and bubbly.
  4. Step 4: Let rest for 5 minutes before serving to allow flavors to meld. Garnish with extra parsley if desired.
