Ingredients
- 2 large portobello mushrooms
- 1 cup cooked quinoa
- 1 cup cherry tomatoes, halved
- 1/2 cup crumbled feta cheese
- 1/4 cup finely chopped red onion
- 2 cloves garlic, minced
- 2 tablespoons olive oil
- 1 teaspoon dried oregano
- Salt and pepper to taste
- Fresh parsley, chopped for garnish
Instructions
- Preheat your oven to 375°F (190°C).
- Clean the portobello mushrooms with a damp cloth and place them on a baking sheet, gill side up.
- In a mixing bowl, combine the cooked quinoa, cherry tomatoes, feta cheese, red onion, garlic, olive oil, oregano, salt, and pepper. Mix until well combined.
- Spoon the quinoa mixture evenly into each portobello mushroom cap, pressing gently to pack the filling.
- Bake in the preheated oven for 25-30 minutes, or until the mushrooms are tender and the filling is golden on top.
- Garnish with fresh parsley before serving.
Cook’s tips
- Use a damp cloth to wipe the mushrooms clean instead of rinsing them, as they absorb water and become soggy.
- Make sure the quinoa is fully cooked and slightly cooled before mixing to prevent it from becoming mushy.
- For extra flavor, toast the quinoa in a dry pan for a few minutes before cooking.
- Let the stuffed mushrooms rest for 5 minutes after baking to allow the filling to set and make them easier to serve.
- If you prefer a golden top, broil the mushrooms for the last 2-3 minutes of baking.
Substitutions
- Use goat cheese or ricotta instead of feta for a creamier texture.
- Substitute cherry tomatoes with diced bell peppers or sun-dried tomatoes.
- Replace quinoa with couscous or orzo for a different grain.
- Use fresh oregano instead of dried (1 tablespoon fresh = 1 teaspoon dried).
- Add toasted pine nuts or walnuts for extra crunch.
Storage & reheating
Store leftovers in an airtight container in the refrigerator for up to 3 days. Reheat in the oven at 350°F for 10-15 minutes or until warmed through.
