- 2 cups fresh spinach chopped
- 1 small onion finely diced
- 2 garlic cloves minced
- 1/4 cup sun-dried tomatoes chopped
- 1/4 cup feta cheese optional, or substitute with vegan feta

- 1/2 tsp Italian seasoning
- Salt and pepper to taste
- 2 tbsp olive oil
For topping:
- 1/4 cup shredded mozzarella or dairy-free cheese alternative

Instructions
Step 1: Prepare the Mushrooms
- Preheat your oven to 375°F (190°C).
- Clean the mushrooms by gently wiping them with a damp paper towel. Remove the stems and use a spoon to scrape out the gills.
- Brush the mushrooms with olive oil, then sprinkle with garlic powder, salt, and pepper. Arrange them cap-side down on a baking sheet lined with parchment paper.
Step 2: Cook the Quinoa
- If you haven’t already, cook the quinoa according to package instructions and set aside to cool slightly.
Step 3: Make the Filling
- Heat 2 tablespoons of olive oil in a skillet over medium heat. Add the diced onion and sauté until translucent, about 3-4 minutes.
- Stir in the minced garlic and cook for another minute until fragrant.
- Add the chopped spinach and cook until wilted, about 2 minutes.
- Remove the skillet from heat and stir in the cooked quinoa, sun-dried tomatoes, feta cheese, parsley, smoked paprika, Italian seasoning, salt, and pepper. Mix until well combined.
Step 4: Assemble and Bake
- Spoon the filling evenly into each mushroom cap, pressing it down gently to pack it in.
- Sprinkle shredded mozzarella and Parmesan cheese (if using) on top of the filling.
- Bake in the preheated oven for 20-25 minutes, or until the mushrooms are tender and the cheese is melted and bubbly.
Step 5: Garnish and Serve
- Remove the mushrooms from the oven and let them cool slightly.
- Garnish with additional fresh parsley and serve warm. Pair with a fresh green salad or roasted vegetables for a complete meal!
Notes
Make Ahead and Storage
Make Ahead:- You can prepare the stuffing up to 2 days in advance and store it in an airtight container in the fridge. When ready to assemble, simply stuff the mushrooms and bake.
- The mushrooms can also be cleaned, prepped, and stored in the fridge until you’re ready to use them.
- Store leftover stuffed mushrooms in an airtight container in the refrigerator for up to 3 days.
- Reheat in the oven at 350°F (175°C) for 10-15 minutes or until warmed through.
- Avoid freezing as the mushrooms may become too watery upon thawing.
