How To Make This Stuffed Mushrooms Recipe

PRO TIP:

You can assemble these easy stuffed mushrooms several hours in advance and then pop them into the oven to bake at the last minute before you’re ready to eat.

STEP ONE: Preheat oven to 400°F. Line a rimmed baking sheet with foil and set it aside.

STEP TWO: Prepare your mushroom caps by removing the stems (save those stems) and brushing off any dirt that may be on your mushrooms.

PRO TIP:

DO NOT run the mushrooms under water, you only want to use a dry paper towel to clean your mushrooms, this will make your mushrooms soggy when cooked.

STEP SEVEN: Transfer your cream cheese and mushroom mixture to a large zip-top or pastry bag.

Snip the end off of the corner of your bag and gently squeeze (or pipe) the filling into each mushroom cap.

The amount of filling you will use per mushroom cap will vary depending on the size of each mushroom.

PRO TIP:

If you do not have a pastry bag or large zip-top bag, you can very easily just scoop the filling into each mushroom cap with a small spoon.
