Ingredients

• 4 large portobello mushroom caps, stems and gills removed
• 2 tablespoons olive oil
• 1 small onion, finely chopped
• 2 cloves garlic, minced
• 1 cup fresh spinach, chopped
• 1/2 cup cherry tomatoes, diced
• 1/2 cup cooked quinoa or couscous
• 1/4 cup crumbled feta cheese (or vegan cheese alternative)
• 1/4 cup grated Parmesan cheese (optional)
• 1/4 cup pine nuts, toasted
• 1 teaspoon dried oregano
• Salt and pepper to taste
• Fresh basil leaves for garnish

Equipment

• Baking sheet or oven-safe dish
• Mixing bowl
• Skillet or frying pan
• Knife and cutting board
• Measuring cups and spoons
• Spoon for stuffing
• Aluminum foil (optional)

Instructions

1. Preheat your oven to 375°F (190°C). Line a baking sheet with parchment paper or lightly grease an oven-safe dish.
2. Prepare the mushrooms: Gently clean the portobello caps with a damp cloth. Remove the stems and carefully scrape out the gills with a spoon to create space for stuffing.
3. Brush the mushrooms on both sides with 1 tablespoon of olive oil, and sprinkle lightly with salt and pepper. Place them gill-side up on the prepared baking sheet.
4. Make the filling: Heat the remaining 1 tablespoon of olive oil in a skillet over medium heat. Add the onion and sauté for 3-4 minutes until translucent.
5. Add garlic and cook for another minute until fragrant. Stir in the chopped spinach and cherry tomatoes, cooking until the spinach wilts, about 2 minutes.
6. Remove from heat and transfer the mixture to a bowl. Stir in the cooked quinoa, pine nuts, crumbled feta, dried oregano, and season with salt and pepper. Mix well to combine.
7. Spoon the filling generously into each mushroom cap, pressing lightly to pack it in.
8. Sprinkle grated Parmesan over the stuffed mushrooms for a golden crust, if using.
9. Bake in the preheated oven for 20-25 minutes until the mushrooms are tender and the filling is heated through and slightly browned on top.
10. Garnish with fresh basil leaves and serve warm.

Tips & Variations

“Feel free to swap out the quinoa for cooked rice, bulgur, or even lentils for a different texture and protein boost.”

For a vegan version, replace feta and Parmesan with your favorite dairy-free cheese or nutritional yeast for a cheesy flavor without dairy. Adding chopped walnuts or cashews can add more crunch and nutrition.

You can also experiment with different veggies in the filling — roasted red peppers, zucchini, or mushrooms make excellent additions. For a Mediterranean twist, add olives and sun-dried tomatoes.

If you want a southwestern flair, try black beans, corn, and a sprinkle of smoked paprika.

To save time, prepare the filling ahead of time and refrigerate until ready to stuff the mushrooms. You can also grill the stuffed mushrooms for a smoky flavor, perfect for summer cookouts.
