Why We Love This Spinach Stuffed Mushroom Recipe
Stuffed mushrooms are always a hit over the holidays, they are so full of flavor and dead easy to make. They are a great option when you are entertaining as they can be prepped ahead of time.
These spinach stuffed mushrooms are full of flavor, some may even say a little decadent! 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!
Variations on Spinach and Artichoke Stuffed Mushrooms
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. Either way, they taste incredible!
To make this dish vegetarian, swap out the Worcestershire sauce for soy sauce, tamari, or coconut aminos.

How to Store and Reheat
Once the mushrooms have been cooked, you can save any extras that are left over. Place the 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.
How to Freeze
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.
Serving Suggestions
You can serve these up as a sit-down appetizer with a side salad, but for me, these stuffed mushrooms make the perfect finger food. I place them on a large serving plate and let everyone help themselves. Serve them alongside some of these recipes for a real feast: Bacon Wrapped Dates with Goat Cheese and Pecans, Apple Pie Baked Brie Appetizer, Cheesy Asparagus Crescent Roll Appetizers, or Edamame Recipe with Everything Bagel Seasoning (Everything Edamame).
How do you wash mushrooms for stuffing?
I like to simply wipe or brush the dirt off of my mushrooms to keep them from getting waterlogged, but a quick rinse and pat dry also works well.
Can you overcook stuffed mushrooms?
Yes! If the mushrooms are overcooked, they will become tough and flavorless.
How do you make stuffed mushrooms not watery?
Ensuring your mushrooms are dry before stuffing them is the key to great stuffed mushrooms. Lightly pat the mushrooms dry before filling them to remove residual moisture.
Do you cook mushrooms covered or uncovered?
You should cook these mushrooms uncovered to help dry them out and crisp up the topping. Covered mushrooms will steam and turn soft.
Why are my stuffed mushrooms rubbery?
Cooking damp mushrooms tends to make them turn rubbery in the oven, as does overcooking them. Make sure to pat your mushrooms dry at every stage, and do not overcook them once stuffed!
How far in advance can you prep mushrooms?
Another great thing about these spinach and artichoke stuffed mushrooms is that you can easily prep them ahead of time. Make the filling and the breadcrumb topping, then store them in separate containers and refrigerate. You can do this 2 or 3 days ahead of time, that way both are ready whenever you cook the mushrooms.
