Ingredients
Serves 4.
- 4 large portobello mushroom caps
- 1 pound boneless, skinless chicken breast, cooked and finely chopped
- 1 cup cooked quinoa
- 1 cup fresh spinach, chopped
- 1 cup cherry tomatoes, diced
- 1/4 cup crumbled feta cheese
- 1/4 cup finely chopped red onion
- 2 garlic cloves, minced
- 1 tablespoon extra-virgin olive oil
- 1 teaspoon dried oregano
- 1/2 teaspoon smoked paprika
- Black pepper, to taste
- Salt, to taste
- Juice of 1/2 lemon
- 2 tablespoons chopped fresh parsley
Instructions
Step 1: Prepare the mushrooms
Preheat the oven to 400°F (200°C).
Gently clean the portobello mushrooms with a damp paper towel. Remove the stems and carefully scrape out the dark gills if desired.
Arrange the mushroom caps on a baking sheet, gill side up.
Brush lightly with olive oil and season with black pepper.
Step 2: Prepare the filling
Heat a skillet over medium heat. Add the remaining olive oil and chopped red onion.
Cook for 3–4 minutes until softened. Add the garlic and cook for another 30 seconds.
Stir in the chopped spinach and tomatoes. Cook until the spinach wilts and some of the tomato moisture evaporates.
Step 3: Add chicken and quinoa
Add the cooked chicken and quinoa to the skillet.
Season with oregano, smoked paprika, black pepper, and a small amount of salt.
Stir well, then add the lemon juice and parsley.
Remove the skillet from the heat and fold in most of the feta cheese.
Step 4: Stuff the mushrooms
Spoon the chicken and quinoa mixture evenly into the mushroom caps.
Sprinkle the remaining feta over the filling.
Step 5: Bake
Bake for approximately 18–25 minutes, depending on the size of the mushrooms.
The mushrooms should become tender and the filling should be thoroughly heated. If using freshly cooked chicken, ensure it reaches an internal temperature of 165°F (74°C).
Allow the mushrooms to rest for a few minutes before serving.

Nutritional Benefits of the Ingredients
Chicken
Chicken breast provides complete protein, which supplies the essential amino acids needed for normal body functions and muscle maintenance.
Quinoa
Quinoa contributes carbohydrates, fiber, and plant protein. It also provides minerals such as magnesium.
Portobello Mushrooms
Mushrooms add texture and flavor while contributing nutrients and relatively few calories.
Spinach and Tomatoes
These vegetables contribute vitamins, minerals, and beneficial plant compounds while adding color and freshness.
Olive Oil
Extra-virgin olive oil supplies predominantly monounsaturated fat and fits well into a Mediterranean-style eating pattern.
Easy Variations
Spinach and Ricotta: Replace the feta with a small amount of ricotta for a milder filling.
Chicken and Chickpeas: Replace half the quinoa with chickpeas for a different texture and additional fiber.
Spicy Mediterranean: Add red pepper flakes and a pinch of chili powder.
Dairy-Free: Leave out the feta and add extra parsley, lemon zest, and chopped olives.
Vegetarian: Replace the chicken with chickpeas or lentils and add extra quinoa. Adjust the quantities to make four generous portions.
How to Make This Meal Even Higher in Protein
- Add extra cooked chicken to the filling.
- Serve with a side of plain Greek yogurt seasoned with lemon and herbs.
- Add a side of edamame or a bean salad.

What to Serve With Stuffed Portobello Mushrooms
These mushrooms can be a complete meal on their own. For a larger dinner, try serving them with:
- A cucumber and tomato salad
- Roasted broccoli
- Steamed green beans
- Lemon-dressed arugula
- A small serving of brown rice
- Roasted zucchini
Meal Prep and Storage
Make ahead: Prepare the chicken and quinoa filling up to two days in advance and refrigerate it in an airtight container.
Refrigeration: Store cooked stuffed mushrooms in the refrigerator and eat within 3–4 days.
Reheating: Reheat in an oven at 350°F (175°C) until heated through. A microwave can also be used.
Freezing: The filling can be frozen separately. Cooked mushrooms may become softer after thawing, so freezing the assembled dish is not ideal for the best texture.
