Ingredients

Instructions

  1. Step 1: Preheat oven to 375°F. Clean 4 large portobello mushroom caps by removing stems and gently wiping caps with a damp cloth. Brush each cap with 2 tbsp olive oil and sprinkle with 1/2 tsp salt and 1/2 tsp black pepper.
  2. Step 2: In a mixing bowl, combine 3/4 cup crumbled feta cheese, 1/3 cup chopped sun-dried tomatoes, 1/4 cup chopped fresh basil, 2 minced garlic cloves, and 1 tsp lemon zest. Toss with remaining 1 tbsp olive oil until mixture is evenly coated.
  3. Step 3: Spoon the cheese and tomato mixture into each mushroom cap, filling each about halfway to leave some of the mushroom visible.
  4. Step 4: Place stuffed mushrooms on a baking sheet and bake for 20 minutes until mushrooms are tender and the filling is slightly golden on top. Let rest for 5 minutes before serving as a flavorful appetizer or side dish.
