How to Make Spinach and Cheese Stuffed Portobello Mushrooms Recipe
Step 1: Prepare Your Oven and Mushrooms
Start by preheating your oven to 375°F (190°C) so it’s ready to go when you need it. Next, gently clean your mushrooms by wiping the caps with a damp cloth or paper towel to remove any grit. Removing the stems and scraping out the gills creates the perfect hollow space to nestle in your delicious filling.
Step 2: Season and Bake the Mushroom Caps
Place your mushroom caps stem side up on a parchment-lined baking sheet. Drizzle them evenly with olive oil and sprinkle garlic powder, salt, and black pepper on top. This step ensures each mushroom is nicely flavored and helps them soften during the initial baking phase for about 10 to 12 minutes.
Step 3: Sauté the Spinach
While the mushrooms are baking, melt butter in a skillet over medium heat. Toss in the fresh spinach and sauté until it wilts down, about 3 to 4 minutes. Removing excess moisture by letting the spinach cool and then pressing it in a towel keeps the filling from getting soggy and makes every bite just right.
Step 4: Mix the Cheese and Spinach Filling
In a mixing bowl, combine ricotta, mozzarella, Parmesan cheese, and crushed red pepper flakes. Once your spinach is dry and chopped finely, fold it into the cheese mixture. The creamy blend clings to the tender spinach, creating a rich, flavorful filling that’s irresistible.
Step 5: Stuff the Mushrooms and Finish Baking
Remove the partially baked mushroom caps from the oven and spoon the spinach and cheese mixture into each one, packing it gently so it stays put while baking. Slide the stuffed mushrooms back into the oven for another 10 to 12 minutes until the cheese melts into a bubbly, golden masterpiece. Let them cool for a moment before serving to enjoy every luscious bite.
How to Serve Spinach and Cheese Stuffed Portobello Mushrooms Recipe

Garnishes
Adding a sprinkle of fresh chopped parsley or basil brightens the dish visually and adds a fresh herbal contrast. A light drizzle of balsamic glaze can also bring a touch of sweetness and acidity that balances the creaminess superbly.
Side Dishes
This dish pairs beautifully with a crisp green salad dressed in lemon vinaigrette to cut through the richness, or a simple side of roasted vegetables bringing warmth and earthiness to the meal. Garlic mashed potatoes or quinoa salad would also complement the stuffed mushrooms wonderfully.
Creative Ways to Present
Serve these stuffed Portobellos on a rustic wooden board for a cozy, inviting vibe or plate them individually on colorful ceramic dishes to highlight the vibrant filling. Garnishing each mushroom with a thin slice of sun-dried tomato or toasted pine nuts adds a delightful textural and flavor twist.
Make Ahead and Storage
Storing Leftovers
Leftover stuffed mushrooms can be stored in an airtight container in the refrigerator for up to 3 days. Make sure they are cooled completely before sealing to preserve fresh flavors and texture.
Freezing
While fresh is best, you can freeze the stuffed mushrooms. Place them in a single layer on a baking sheet to freeze individually, then transfer to a freezer-safe container or bag. They will keep well for up to 2 months. Thaw overnight in the refrigerator when ready to use.
Reheating
Reheat leftovers in the oven at 350°F (175°C) for about 10 to 15 minutes until warmed through and cheese is bubbly again. Avoid microwaving for best texture, as it can make the mushrooms soggy.
