Quinoa Stuffed Portobello Mushrooms Cooking Guide

Step 1: Prepare the Quinoa
Begin by rinsing the quinoa under cold water to remove its natural coating, called saponin, which can give it a bitter taste. In a medium saucepan, combine the rinsed quinoa and water. Bring to a gentle boil over medium heat, then reduce the heat to low and cover. Allow the quinoa to simmer for about 15 minutes, or until all the water is absorbed and the quinoa is fluffy. Once done, remove from heat and let it sit covered for another 5 minutes. Fluff with a fork and set aside.
Step 2: Preheat the Oven
While the quinoa cooks, preheat your oven to 375°F (190°C). This will ensure that the mushrooms roast perfectly and develop a beautiful flavor.
Step 3: Prepare the Portobello Mushrooms
Carefully remove the stems from the portobello mushrooms and gently scrape out the gills using a spoon. This will create more space for the filling and prevent the mushrooms from becoming too watery during baking. Brush each mushroom cap with olive oil on both sides and place them on a baking sheet, gill side up.
Step 4: Make the Filling
In a mixing bowl, combine the cooked quinoa, diced tomatoes, whole-grain bread crumbs, chopped basil, feta cheese, balsamic vinegar, black pepper, crushed red pepper flakes, and salt to taste. Mix until all ingredients are well incorporated.
Step 5: Stuff the Mushrooms
Generously spoon the quinoa filling into each portobello mushroom cap, packing it lightly to ensure it holds together during baking.
Step 6: Bake
Place the stuffed mushrooms in the preheated oven and bake for 20-25 minutes, or until the mushrooms are tender and the filling is golden brown on top. The smell will be irresistible!
Step 7: Serve
Once baked, remove the mushrooms from the oven and let them cool for a few minutes. Serve warm, garnished with extra fresh basil if desired. Enjoy your quinoa stuffed portobello mushrooms as a delightful main or side dish!
Health-Conscious Tweaks

- Swap the olive oil for avocado oil for a different flavor profile and higher smoke point.

Cook’s Commentary
Quinoa stuffed portobello mushrooms are incredibly versatile. You can easily customize the filling to suit your tastes or use leftover grains and veggies from your fridge. If you’re not a fan of feta, any cheese that melts well can be substituted, or you can omit cheese entirely for a lighter option. The key is to balance the flavors in the filling with the natural earthiness of the mushrooms. Don’t be afraid to experiment with herbs and spices; fresh thyme or oregano could add a delightful twist!
Keep It Fresh: Storage Guide
If you have leftovers, store them in an airtight container in the refrigerator for up to 3 days. Reheat in the oven or microwave until warmed through. For longer storage, consider freezing the stuffed mushrooms before baking. Place them in a freezer-safe container and freeze for up to 2 months. When you’re ready to enjoy, simply bake from frozen, adding a few extra minutes to the cooking time.
