Ingredients
(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)
4 large portobello mushroom caps, stems and gills removed
1 tbsp olive oil
salt and pepper to taste
½ tsp garlic powder
1 cup fresh spinach
½ cup cherry tomatoes, halved
4 oz part-skim mozzarella, shredded or 4 fresh mozzarella slices
2 tbsp marinara sauce optional
1 tbsp grated parmesan
1 tsp Italian seasoning
fresh basil or parsley, for garnish
Directions
Start by preheating your oven to 200°C (400°F). Line a baking sheet with parchment paper or lightly grease it to prevent sticking.
Clean the portobello mushroom caps gently with a damp paper towel. Remove the stems and scrape out the gills using a spoon to create space for the filling.
Brush each mushroom cap with olive oil on both sides. Season them with salt, pepper, and garlic powder. Place them on the prepared baking sheet, gill-side up, and bake for about 8–10 minutes to release excess moisture.
While the mushrooms are baking, prepare the filling. In a pan over medium heat, lightly sauté the spinach until wilted, which should take about 2–3 minutes. Remove from heat and set aside.
Take the mushrooms out of the oven and carefully drain any liquid that has collected inside them. This step helps prevent sogginess.
If using marinara sauce, spread a small amount inside each mushroom cap. Then layer the spinach evenly, followed by the halved cherry tomatoes.
Top each mushroom with shredded mozzarella or a slice of fresh mozzarella. Sprinkle grated parmesan and Italian seasoning over the top.
Return the stuffed mushrooms to the oven and bake for another 10–12 minutes, or until the cheese is melted and slightly golden.
Once done, remove from the oven and let them cool slightly. Garnish with freshly chopped basil or parsley before serving.
Servings and timing
This recipe serves 4 people, with one stuffed mushroom per serving as a main dish or two halves as a side.
Preparation time: 10 minutes
Cooking time: 20–25 minutes
Total time: approximately 30–35 minutes
Variations
You can easily adapt this recipe to suit different tastes. Add cooked chicken strips or grilled turkey pieces for extra protein if you want a more filling meal.
For a richer flavor, swap part-skim mozzarella with full-fat mozzarella or add a small amount of cream cheese to the filling.
If you enjoy a bit of heat, sprinkle red pepper flakes over the mushrooms before baking. You can also add sautéed onions or bell peppers for extra texture and sweetness.
To make it dairy-free, use plant-based cheese alternatives that melt well. The dish will still be flavorful thanks to the herbs and vegetables.
Storage/Reheating
Store any leftovers in an airtight container in the refrigerator for up to 3 days. Make sure the mushrooms have cooled completely before storing.
To reheat, place the mushrooms in an oven at 180°C (350°F) for about 10 minutes until warmed through. This helps maintain their texture better than using a microwave.
If using a microwave, heat in short intervals to avoid making the mushrooms too soft.
Freezing is not recommended, as mushrooms tend to release water and become mushy when thawed.
