These spinach stuffed mushrooms are one of the easiest appetizers I make, and they’re always a crowd-pleaser during the holiday season. The recipe couldn’t be simpler—I take fresh mushrooms, pack them with a creamy mix of spinach, artichoke, and Parmesan, and finish them with a sprinkle of golden, crispy breadcrumbs. They disappear fast every single time!

Why We Love This Spinach Stuffed Mushroom Recipe
Stuffed mushrooms are always a hit over the holidays—they are so full of flavor and so easy to make. I love making them when I’m entertaining, because they can be prepped ahead of time helping me get one thing off my to-do list.
These spinach stuffed mushrooms are full of flavor. The filling is rich and creamy, and I promise you that one isn’t enough! I always serve stuffed mushrooms at some point during the holiday season, and I think these ones are my favorite!
I like getting larger mushroom caps so that they’re easy to stuff, but you can use smaller ones if you want something more bite-sized or, for a heartier appetizer, use portobello mushrooms. Whichever you choose, don’t worry, they taste incredible!

How to Make Spinach Stuffed Mushrooms Step by Step
Get the oven going and prepare a baking pan: Preheat your oven to 350°F and adjust the oven rack to the middle position. Line a rimmed baking sheet with parchment or aluminum foil and set a wire rack inside. Spray the rack with nonstick cooking spray.
Make the topping: Place 1 slice bread, 1 tbsp panko breadcrumbs, and 1 tbsp freshly grated Parmesan cheese in a food processor fitted with the metal attachment. Pulse the mixture for 3-4 seconds and then pour in 1 tbsp olive oil and pulse 1-2 times. Set aside while you prepare the remaining ingredients.
Prep the mushrooms: Use a paper towel to pat 24 white button mushrooms dry. Brush them lightly with 2 tbsp melted unsalted butter and place them on the prepared baking sheet around 1-2 inches apart.
Cook the onions: Heat 1 tbsp butter in a large skillet over medium heat and then add 1 tbsp oil. When the oil/butter is heated, add ½ a diced yellow onion and cook, stirring often, until softened.
Add the artichokes: Add 9 oz. of thawed, squeezed dry, and chopped frozen artichoke hearts and cook, stirring often, for 4-5 minutes, or until they are lightly browned.
Season the filling: Stir in 1 minced garlic clove and cook another 30 seconds, then add the remaining 1 tbsp unsalted butter and stir until melted.
Thicken the filling: Sprinkle 2 tbsp all-purpose flour over the vegetable mixture and cook for 1 minute, stirring continuously.
Add the cream: Slowly stir in 1 cup half and half, ¾ cup freshly grated Parmesan cheese, 1½ tsp fresh lemon juice, 1 tsp hot sauce, 1 tsp Worcestershire sauce, and ½ tsp kosher salt. Reduce the heat to low and simmer, stirring occasionally, for 3 minutes or until the mixture has thickened.
Add the spinach: Remove the filling from the heat, add 5 oz. thawed and squeezed dry frozen chopped spinach, and stir well.
Stuff the mushrooms: Spoon the artichoke/spinach filling into the mushroom caps, packing down and rounding the filling over the tops.
Top the mushrooms: Top the filled mushrooms with the bread mixture, pressing down lightly so the topping sticks to the filling.
Bake the mushrooms: Bake for 20-25 minutes at 350°F or until the tops are golden brown and mushrooms are cooked through. Remove from the oven, let rest 4 minutes, and serve.
How to Store
Store any leftover stuffed mushrooms in resealable bags or airtight containers and store them in the refrigerator. They will keep for up to 4 days. Reheat in a 350°F oven uncovered for 5-10 minutes, or until warmed through.
If you’d like to freeze these mushrooms, I recommend doing so before baking them. Let the filling cool to room temperature, then stuff the mushrooms and place them in a single layer on a lined baking sheet. Freeze until solid, about 1-2 hours, then transfer to an airtight container or Ziplock bag to store for up to 3 months. Bake directly from frozen, adding an extra 5-10 minutes to the final bake time.
To prep in advance, I make the filling and the breadcrumb topping, then store them in separate containers and refrigerate. I like to do this 2 or 3 days ahead of time; that way, they are ready whenever I want to cook the mushrooms.
Serving Suggestions
Though you can serve these as a sit-down appetizer with a side salad, I like to serve stuffed mushrooms as finger food. I place them on a large serving plate and let everyone help themselves. To add variety to the plate, I’ll also prepare sweet and savory bacon wrapped dates with goat cheese, or a creamy apple pie baked brie, and to round things out, I like to add asparagus Crescent Rolls.
