The Story & Intro
Hi, I’m Marilyn born and raised on the beautiful island of Crete, where food is more than just nourishment; it’s a language of love. 🍄
Every Halloween, I like to take traditional recipes and add a playful twist that brings both smiles and shivers. These Stuffed Mushrooms with Halloween Garnish were inspired by the time my grandmother taught me to make herb-stuffed mushrooms for Sunday lunches. I still remember the smell of olive oil sizzling with garlic filling our kitchen.
Years later, I decided to give her comforting recipe a spooky makeover. By topping each mushroom with an adorable “olive spider,” they became the perfect Halloween appetizer equal parts delicious and delightfully eerie.
If you’re looking for something elegant yet easy for your Halloween party, these Parmesan and herb-stuffed mushrooms are your go-to. They’re bite-sized, savory, and irresistibly creamy, with just the right crunch on top. And those olive spiders? They’ll be the talk of your spooky spread!
So grab your apron (and maybe a little witch hat) let’s make some Halloween magic happen in your kitchen.

Ingredients
Here’s everything you’ll need for about 24 stuffed mushrooms:
- 24 large white button mushrooms, stems removed and cleaned
- 2 tablespoons olive oil (plus extra for drizzling)
- 2 cloves garlic, minced
- 1/4 cup finely chopped mushroom stems
- 1/4 cup breadcrumbs
- 1/3 cup grated Parmesan cheese
- 2 tablespoons cream cheese, softened
- 2 tablespoons fresh parsley, finely chopped
- 1/2 teaspoon dried thyme
- Salt and black pepper to taste
- 12 black olives (for the spider garnish)
- Optional: a pinch of red pepper flakes for a little heat
Step-by-Step Instructions
Step 1: Prepare the Mushrooms
Gently remove the stems from your mushrooms and set them aside. Wipe the caps clean with a damp paper towel don’t soak them in water or they’ll get soggy. Finely chop a few of the stems; they’ll add flavor to your filling.
Step 2: Make the Filling
In a skillet, heat olive oil over medium heat. Add the chopped mushroom stems and garlic, and sauté until fragrant. Stir in breadcrumbs, Parmesan, cream cheese, parsley, thyme, salt, and pepper. Mix until the filling is soft and well combined.

Step 3: Fill and Bake the Mushrooms
Preheat your oven to 375°F (190°C). Arrange the mushroom caps on a parchment-lined baking sheet. Spoon a generous amount of filling into each cap, pressing lightly so it stays in place. Drizzle a little olive oil on top.
Bake for 18–20 minutes, or until golden and slightly crispy on top.

Step 4: Create the Olive Spiders
While the mushrooms bake, make your spooky garnish! Slice each black olive in half lengthwise one half is the spider’s body. Cut the other half into thin slices for legs. Once the mushrooms are baked and slightly cooled, place an olive “body” on top and arrange the legs around it to look like a tiny spider.
Serving the Stuffed Mushrooms
Serve your Halloween stuffed mushrooms warm on a dark platter or rustic tray to enhance their spooky charm. I love adding a few sprigs of rosemary or thyme around the edges they look like a forest floor where the little olive spiders might live!
Pair them with a crisp white wine or sparkling apple cider for adults, and for the kids, a fun pumpkin-orange punch.
These little bites disappear fast at parties, so I always make a double batch. The rich flavor of Parmesan, herbs, and mushrooms creates a perfect savory balance, while the olive spiders add just the right playful touch.
