Ingredients
• 1 cup / 185g cooked orzo
• 1/2 cup / 120ml tomato sauce
• 1/2 cup / 55g shredded mozzarella cheese
• 1 medium tomato, chopped
• 1 tsp / 1g dried oregano
• Salt and freshly ground black pepper, to taste
• 1 large Portobello mushroom, about 4-5 inches / 10-12 cm in diameter
• 1 tbsp / 15ml olive oil, for brushing
Instructions
1. Prep the Oven and Mushroom: Preheat your oven to 375°F / 190°C. Lightly oil a small baking dish. To prepare the portobello, gently wipe it clean with a damp paper towel. Twist off the stem and, using a spoon, gently scrape out the black gills from the underside of the cap.
2. Mix the Filling: In a medium bowl, combine the cooked orzo, tomato sauce, shredded mozzarella, chopped tomato, and dried oregano. Season generously with salt and freshly ground black pepper and mix until everything is well incorporated.
3. Stuff and Bake: Brush the entire portobello mushroom—cap and underside—with olive oil and place it gill-side-up in your prepared baking dish. Mound the orzo mixture generously into the mushroom cap.
4. Bake to Perfection: Transfer the baking dish to the preheated oven and bake for 25 to 30 minutes. The mushroom is ready when it’s tender and the cheese on top is melted, bubbly, and slightly golden. Serve immediately.

Pro Tips
• Scraping out the dark gills prevents your filling from turning a muddy brown color and removes any slightly bitter taste.

• Feel free to swap the mozzarella with provolone for a sharper taste or add a sprinkle of Parmesan cheese on top for a crispy, salty crust.
FAQ
Q: Can I make this stuffed portobello mushroom vegan
A: Absolutely! To make this recipe vegan, simply use your favorite brand of dairy-free shredded mozzarella cheese. The rest of the ingredients are naturally plant-based, making this an easy and delicious vegan adaptation.
Q: Is this vegetarian recipe a good source of protein
A: Yes, this dish provides plant-based protein from the mushroom and orzo. To increase the protein content further, consider using a protein-fortified or whole-wheat orzo, or mix in 1/4 cup of cooked lentils or white beans with the filling.
Q: How can I make this recipe gluten-free
A: Making this recipe gluten-free is very simple. Just substitute the regular orzo with a certified gluten-free orzo pasta. You could also use cooked quinoa or brown rice as an excellent alternative for the filling.
Q: How should I store and reheat leftover stuffed mushrooms
A: Store any leftovers in an airtight container in the refrigerator for up to 3 days. For the best results, reheat the mushroom in an oven preheated to 350°F / 175°C for 10-15 minutes, or until it’s warmed through and the cheese is bubbly again.
