Ingredients

Before we can get into the kitchen to make these Walnut and Blue Cheese-Stuffed Mushrooms, we’ll want to gather up some fresh ingredients. Here’s what you’ll need for this recipe:

fresh mushrooms: I recommend mini portobellos here. The meaty base that holds all the delightful fillings together, offering a savory bite.
seasoned breadcrumbs: Adds a touch of crunch and helps bind the stuffing, enhancing the texture.
parmesan cheese: Introduces a salty, nutty depth, melding flavors together.
sour cream: Ensures a rich creaminess, making every bite a velvety pleasure.
flat leaf parsley: Brings a burst of freshness, brightening the dish.
garlic: A subtle kick, adding aromatic depth to the mix.
black pepper: Just a hint of spice to balance and elevate the overall taste.
blue cheese: The star of the show, lending its robust and tangy profile.
walnuts: Introducing a delightful crunch and earthiness, a match made in heaven with blue cheese.
olive oil: For that smooth finish, ensuring the mushrooms roast to perfection.

Frequently Asked Questions

Can I use another type of mushroom?

Absolutely! While mini portobellos are recommended for their meaty texture and flavor, you can also use white button mushrooms or cremini mushrooms. Just ensure they’re large enough to hold the stuffing.

I’m not a fan of blue cheese. Can I substitute it?

Sure thing! Feta or goat cheese could be a good alternative. Keep in mind that each cheese will lend a different flavor profile to the dish.

Can these be made in advance?

Yes! You can prepare the stuffing and fill the mushrooms a day in advance. Store them in the refrigerator covered with plastic wrap. When you’re ready to serve, simply bake as directed.

How do I store leftovers?

Store any leftover stuffed mushrooms in an airtight container in the refrigerator for up to 2 days. Reheat them in the oven for best results.

What’s the best way to toast the walnuts?

Spread the walnuts in a single layer on a baking sheet and toast in a preheated oven at 350 degrees F for 5-7 minutes or until they become fragrant. Keep an eye on them to avoid burning.
