Pin Mediterranean Stuffed Portobello Mushrooms is my favorite vegetarian pick when I need a hearty dish that feels both impressive and nourishing. These meaty mushroom caps become a star protein main, loaded with a sunny quinoa and feta cheese filling brightened by fresh herbs and briny sun-dried tomatoes. Whenever I serve them at weeknight meals or small gatherings, no one ever misses the meat and there is never a bite left behind.
The first time I made these, I worried my meat-loving friends would be underwhelmed, but everyone wanted seconds and even asked for the recipe to bring home. This became a go-to for cool evenings or whenever I want to brighten up dinnertime.
Ingredients
- Portobello mushroom caps: Pick big, firm caps with tight edges for best structure
- Olive oil: Helps in roasting and adds classic Mediterranean richness Look for extra-virgin for the deepest flavor
- Garlic: Freshly minced brings bold aroma and warmth
- Salt and pepper: Choose coarse kosher salt and fresh-ground pepper to build a tasty base
- Cooked quinoa: Fluffy and nutty Lightly cool before mixing so the stuffing holds together
- Sun-dried tomatoes: Pack in a tangy punch Oil-packed ones are most tender
- Baby spinach: Fresh leaves wilt down and add a pop of color Go for crisp greens with no sogginess
- Feta cheese: Crumbled feta adds creamy saltiness Buy in a block for best flavor
- Pine nuts: Toast lightly for crunch and a buttery taste
- Fresh basil: Bright and aromatic Fresh is essential here
- Oregano: Either chopped fresh for boldness or good quality dried
- Balsamic vinegar: A little tang lifts all the flavors Make sure it is thick and aromatic
- Parmesan cheese: Grated for a golden crust on top Use Parmigiano-Reggiano if possible
- For garnish: Fresh basil, lemon wedges, and more feta for brightness and presentation
Instructions
- Prep the Mushrooms:
- Wipe mushroom caps clean with a damp towel then carefully break off stems and scrape out the dark gills using a spoon This step gives room for a generous filling and removes any bitterness Brush both sides of each cap with olive oil and season with salt and pepper Place gill side up on a sturdy baking sheet
- Make the Spinach Filling:
- In a large skillet warm olive oil over medium heat Add garlic and stir constantly for thirty seconds until aromatic but not browned Immediately tumble chopped spinach into the pan Stir and cook two minutes until just wilted then remove from heat so the greens stay vibrant
- Combine Mediterranean Stuffing:
- In a large bowl toss cooked quinoa with chopped sun-dried tomatoes add the wilted spinach and garlic crumble in feta add toasted pine nuts chopped basil oregano and drizzle the balsamic vinegar Mix well Taste and season with more salt and pepper if needed The mixture should be moist but not soggy
- Stuff the Mushrooms:
- Spoon the quinoa mixture into each cap pressing lightly to mound stuffing over the top The caps will hold more than you expect so fill generously Sprinkle each with a shower of grated Parmesan for a golden crust
- Bake to Perfection:
- Slide the baking sheet into a hot oven Roast twenty to twenty-five minutes until the mushrooms are yielding and the stuffing is heated through Watch for the cheese to turn just golden on the edges
- Garnish and Serve:
- Transfer carefully to plates Scatter with torn fresh basil leaves Serve with lemon wedges so everyone can squeeze over a hit of brightness Add extra feta at the table for those who want extra creaminess
Pin I am always amazed how the sun-dried tomatoes transform the filling The sweet tang is the flavor my family now asks for most often and reminds us of summer holidays in the Mediterranean We make a double batch just so there are leftovers for lunch
Storage Tips
Stuffed mushrooms keep well for up to two days in the fridge Store them in an airtight container and reheat gently in the oven to crisp up the tops If you want to freeze them prep right up to the stuffing stage then wrap each cap tightly and freeze on a tray Once fully frozen transfer to a bag and bake straight from the freezer adding a few extra minutes to the cook time
Ingredient Substitutions
Swap quinoa for cooked brown rice or millet for a different grain base If you need to skip pine nuts try chopped toasted almonds or seeds Goat cheese can stand in for feta if you want a tangy twist No sun-dried tomatoes on hand Roasted red peppers work in a pinch
Serving Suggestions
Serve stuffed portobellos hot from the oven with a crisp green salad or on a platter as part of a mezze spread These go beautifully with lemony roasted potatoes and a drizzle of herbed yogurt sauce They are also hearty enough to stand alone as a main
