Feta, Tomato & Basil Stuffed Portobello Mushrooms

Lately I've been obsessed with stuffed portobello mushrooms. They're a great vegetarian option that's hearty enough to serve as a main dish. Plus SP loves mushrooms so it's almost a foregone conclusion that he'll enjoy dinner. These Goat Cheese, Tomato & Basil Stuffed Portobello Mushrooms are another delicious recipe from Brianna over at Oiishi Food.

Just like the last time I made one of her stuffed portobello recipes, I modified the directions for the oven. We use a charcoal grill and it can be hard to control the heat of the fire.

I decided to change the cheese to feta because I needed some for another recipe later in the week. I would love to try these with goat cheese because I love the creaminess, but the feta worked very well. I also realized these were a lot like the Greek Pita Pizzas I made awhile back, which call for shredded mozzarella on top, so I added some to the mushrooms. I also wilted the spinach before adding it to the mushrooms because it tends to give off a lot of liquid and I didn't want to water them down.

These were hearty and delicious, served with crusty bread to sop up all the sauce from the balsamic, oil and tomatoes. Thanks for another winner, Brianna!

Feta, Tomato & Basil Stuffed Portobello Mushrooms
Modified from Oishii Food

4 portobello mushrooms
Balsamic vinegar
Extra virgin olive oil
Dried oregano
Kosher salt & freshly ground pepper
1 large tomato, chopped
2 garlic cloves, minced
4 tablespoons chopped fresh basil
1 teaspoon dried oregano
4oz feta cheese, crumbled
Cooking spray
1/2 bag baby spinach
4oz mozzarella, shredded

Preheat the oven to 425. Line a baking sheet with parchment paper.

Using a knife, scrape the brown gills out of the mushroom caps. Discard gills. Remove and discard stems. Place mushroom caps on a large plate and drizzle both sides with balsamic vinegar, olive oil, and season with dried oregano, salt and pepper.

In a small bowl, toss the chopped tomato with the garlic, fresh basil and oregano, crumbled feta and a little splash each of balsamic vinegar and olive oil. Season to taste with salt. Set aside.

Place the mushrooms, gill side facing down, on the baking sheet and roast for 10 minutes. Flip so the mushrooms are gill side up and roast for another 5 minutes.

While the mushrooms are cooking, spray a non-stick skillet with cooking spray. Heat over medium heat, then add the baby spinach. Toss until wilted. Allow to cool slightly.

Remove the mushrooms from the oven. Place a few pieces of wilted spinach in the caps, then top with a few spoonfuls of the tomato and feta mixture. Sprinkle with some shredded mozzarella cheese.

Return to the oven and cook until the mushrooms are tender and the filling is warmed, about 5-7 minutes.
