Stuffed portobello mushrooms make a hearty vegetarian main. Meaty mushroom caps are filled with quinoa cooked in broth, sautéed onion, zucchini and red pepper, fresh parsley, dill and oregano, pine nuts and lemon juice, then baked until tender.
Preparing the Caps
Remove the stems and scrape out the dark gills with a spoon; they can make the filling look muddy and taste slightly bitter. Brush the caps with olive oil and season them. Pre-bake them for 10 minutes if you want them extra tender, then fill and bake again.
Kosher Notes
These stuffed mushrooms are pareve, so they work for vegetarians at a meat meal like Shabbat dinner. Check herbs for insects, and use vegetable broth with a reliable hechsher.
Make-Ahead
The quinoa filling can be made 2 days ahead. Leftovers keep for 3 days; reheat in a 350°F oven for 10 to 15 minutes. Almonds or sunflower seeds work in place of pine nuts.

Method
- Preheat oven to 400°F (200°C). Line a baking sheet with parchment paper.
- Remove stems from portobello mushrooms and scrape out the dark gills with a spoon. Brush both sides of mushroom caps with 2 tablespoons olive oil and season with salt and pepper. Place gill-side up on prepared baking sheet and let sit 15 minutes.
- Meanwhile, rinse quinoa in a fine mesh strainer until water runs clear. In a medium saucepan, bring vegetable broth to a boil. Add quinoa, reduce heat to low, cover and simmer 15 minutes until liquid is absorbed. Remove from heat and let stand 5 minutes, then fluff with a fork. Set aside to cool.
- Heat remaining 2 tablespoons olive oil in a large skillet over medium heat. Add onion and cook 5 minutes until softened. Add garlic and cook 1 minute until fragrant. Add zucchini and bell pepper, cook 6-8 minutes until vegetables are tender and moisture has evaporated.
- Remove skillet from heat. Stir in cooked quinoa, parsley, dill, oregano, pine nuts, lemon juice, salt, and pepper. Mix well and taste for seasoning.
- Pat mushroom caps dry with paper towels. Divide quinoa mixture evenly among mushroom caps, mounding it slightly.
- Bake 20-25 minutes until mushrooms are tender and filling is heated through. Serve immediately.
