Vegetarian Stuffed Mushrooms Spinach

Last winter my friend kept talking about these stuffed mushrooms she'd had at a dinner party, describing them like they were some kind of revelation. I finally just made them myself on a rainy Sunday, and she was absolutely right.

I brought these to a potluck last month and watched three different people ask for the recipe within ten minutes. Something about that golden cheesy top makes people gravitate toward the platter immediately.

Ingredients

• 16 large white button mushrooms: Look for caps that feel firm and have plenty of room for filling
• 1 tablespoon olive oil: This helps sauté the stems and garlic into something fragrant
• 2 cloves garlic, minced: Fresh garlic makes all the difference here
• 150 g fresh spinach, chopped: Frozen spinach works too but fresh keeps the texture lighter
• 120 g cream cheese, softened: Let it sit out for 20 minutes for easier mixing
• 60 g grated Parmesan cheese: Adds that salty umami depth
• 60 g shredded mozzarella cheese: Creates the beautiful golden top
• 1 tablespoon fresh parsley, chopped: Brightens up all that rich cheese
• ½ teaspoon salt and ¼ teaspoon black pepper: Adjust to taste after mixing
• ¼ teaspoon crushed red pepper flakes: Totally optional but adds a nice warmth
• 2 tablespoons breadcrumbs: Use gluten free if needed
• 1 tablespoon olive oil: For drizzling over the tops before baking

Instructions

Preheat your oven:

Set it to 190°C (375°F) and line a baking tray with parchment paper for easy cleanup

Prep the mushrooms:

Clean the caps gently with a damp cloth, remove the stems, and finely chop those stems

Sauté the aromatics:

Heat 1 tablespoon olive oil in a skillet over medium heat, add the chopped stems and garlic, cook for 2 minutes until fragrant

Wilt the spinach:

Toss in the chopped spinach and cook for 2 to 3 minutes until it collapses, then remove from heat and let it cool slightly

Make the filling:

Combine the cooled spinach mixture, cream cheese, Parmesan, mozzarella, parsley, salt, pepper, and red pepper flakes in a bowl and mix until smooth

Stuff the mushrooms:

Spoon the filling generously into each cap, really packing it in there, and arrange them on your prepared tray

Add the topping:

Sprinkle breadcrumbs over each stuffed mushroom and drizzle with olive oil

Bake until golden:

Slide them into the oven for 20 to 25 minutes until the mushrooms are tender and those tops are beautifully browned

Garnish and serve:

Sprinkle with extra parsley and bring them to the table while theyre still warm

These became my go to appetizer after I realized I could prep everything ahead of time and just pop them in the oven when guests arrive. The house smells incredible while they bake.

Making Them Your Own

Sometimes I swap in kale for the spinach or add chopped sun dried tomatoes to the filling for extra tang. The basic formula works with whatever cheese you have in the fridge too.

Serving Ideas

These work as a first course, a side with roasted chicken, or as part of a vegetarian tapas spread. I've even served them for brunch alongside a frittata.

Storage and Make Ahead

You can stuff the mushrooms up to a day ahead and keep them covered in the refrigerator. Bake them just before serving, and they reheat surprisingly well in a 180°C oven for about 10 minutes.

• Freeze unbaked stuffed mushrooms on a tray, then transfer to a bag
• Add a couple extra minutes baking time if baking from frozen
• The texture is best eaten the same day theyre baked

Every time I make these now, I think about that rainy Sunday afternoon when a simple craving turned into one of my most requested recipes.
