Ingredients for Stuffed Portobello Mushrooms with Spinach and Feta
Essential Ingredients:
Portobello Mushrooms: These large, meaty mushrooms are the star of the dish.
Tips for Picking the Best Ones: Choose mushrooms with firm, smooth caps and avoid any that feel slimy or have cracked edges.
Fresh Spinach: Forms the base of the filling, offering a fresh, slightly sweet flavor.
Why Fresh is Better Than Frozen: Fresh spinach delivers a more vibrant taste and texture.
Feta Cheese: The creamy tang of feta complements the spinach and mushrooms.
Crumbled or Block?: Block feta offers a creamier texture and fresher taste.
Additional Ingredients:
Garlic: Adds a punch of flavor when sautéed with spinach.

5 Steps to Perfect Stuffed Portobello Mushrooms with Spinach and Feta
Step 1: Cleaning and Preparing the Mushrooms
Gently wipe the mushroom caps with a damp paper towel to remove dirt.
Remove the stems and use a spoon to scrape out the gills for more space and a milder flavor.
Brush the caps lightly with olive oil to prevent them from drying out during baking.
Step 2: Sautéing Spinach to Perfection
Heat a tablespoon of olive oil in a skillet over medium heat.
Add minced garlic and cook until fragrant (about 1 minute).
Toss in fresh spinach and cook until wilted. Drain excess liquid to prevent soggy mushrooms.
Step 3: Combining Feta and Spinach for the Filling
In a bowl, mix sautéed spinach with crumbled feta cheese. Add a pinch of salt, pepper, and your favorite herbs like oregano or thyme.
Step 4: Baking the Stuffed Mushrooms
Preheat your oven to 375°F (190°C).
Place the mushroom caps on a baking tray lined with parchment paper, cap side down.
Fill each mushroom generously with the spinach-feta mixture.
Optional: Sprinkle breadcrumbs on top for added crunch.
Bake for 20–25 minutes or until the mushrooms are tender and the filling is slightly golden on top.
Step 5: Finishing Touches
Sprinkle with fresh parsley or drizzle with balsamic glaze for an extra layer of flavor.

FAQs About Spinach and Feta Stuffed Portobello Mushrooms
How Do I Keep the Mushrooms from Getting Soggy?
To prevent your stuffed Portobello mushrooms from becoming soggy, start by removing the stems and gently scraping out the gills before stuffing. This helps to reduce excess moisture.

When you’re ready to serve, just pop them into the oven for a few minutes longer if necessary to ensure they’re heated through.

While feta adds a wonderful tangy flavor, you can experiment with other cheeses depending on your preferences. Some great alternatives include goat cheese, mozzarella, ricotta, or even Parmesan for a sharp, nutty taste. You can also try a blend of these cheeses for extra flavor complexity.
