I love this time of year when it’s totally acceptable to graze on tons of decadent appetizers for weeks on end.  Ahh the holidays.

Although this year there are fewer parties and get-togethers - understandably so – that just makes me appreciate my time with family and friends so much more.

I’m sure you can relate.

I hope you’re able to spend some rich quality time with your loved ones.  I know there are a lot of challenges currently with traveling and getting together - savor every moment my friend.  We are not promised tomorrow.

If you don’t know this about me – I’m ALL about appetizers. 

There’s nothing more yummy than a table full of all my favorite finger food… baked brie with honey, mini salmon cakes, garlic parmesan instant pot chicken wings, and some lemon pepper shrimp – bring it on!!!!

I love that I can eat a little bit of everything I love.  They say “Variety is the spice of life…” and I couldn’t agree more.

Appetizers are so my jam and today I’m sharing another favorite recipe of mine… spinach feta stuffed mushrooms with walnuts!

Can we talk about mushrooms for just a minute?  I gathered some good info from The Mushroom Council that I would love to share…

How to Clean, Shop for, and Store Mushrooms

How to Clean Mushrooms:

• I don’t prefer to use running water, because mushrooms already contain a lot of moisture. 
• Instead, brush off any debris with a very slightly damp paper towel.
• You can also purchase a mushroom brush for this task, which has very soft bristles… not the same thing as a veggie brush!  

Shopping for Mushrooms:

• Choose firm, fresh mushrooms that have a smooth appearance… if they seem at all soggy, move on.
• Mushrooms should be dry, but not dried out, and appear plump.
• Mushrooms with a “closed veil” under the cap have a more delicate flavor, while mushrooms with an open veil (you can see all the gills) will typically have a fuller richer flavor.

How to Store Mushrooms:

• Leave mushrooms in their original packaging, or else put them in a paper bag to give them a little longer storage life.
• Speaking of storage, mushrooms have a max “fridge” life of about one week… use ‘em or lose ‘em!
• Fresh mushrooms should not be frozen.  But you can saute mushrooms and then freeze them for up to a month.

Ok class dismissed.  Moving on to this yummy stuffed mushroom recipe.

I’ve been making these stuffed mushroom caps for so many years and they’ve always gotten rave reviews.  So I thought it was about time I shared them with you.

Stuffed Mushrooms Recipe with Spinach and Cheese

First, preheat your oven to 375°F.

Line 2 baking sheets with parchment paper.  Sprinkle the mushrooms with salt and pepper and place them rounded side down, in a single layer on the baking sheets.  

Bake mushrooms for 15 minutes. Turn the mushrooms over and bake them or another 15 minutes. 

While they’re baking, heat 1 tablespoon olive oil in a medium sized saute pan then add the chopped onions… Saute on medium-high heat for about 5 minutes.  

Then add the minced garlic and cook for one more minute.

Stir in the spinach, feta, cream cheese, walnuts, chicken stock, thyme, parsley, and salt and pepper, and cook until everything is blended together - about 5 minutes.

Turn the mushrooms over on the baking sheet.  Spoon 1 generous tablespoon of the spinach filling into each mushroom cavity. (Filled mushrooms can be prepared 1 day ahead… just cover the baking sheet and refrigerate.)

Sprinkle the mushrooms with Parmesan cheese and bake until heated through, about 10-15 minutes.  

Transfer the mushrooms to a platter, sprinkle with chopped parsley and serve warm.

This stuffed mushroom recipe is so hearty and delicious! 

The cream cheese and feta make them so cheesy and  flavorful, the spinach is a little earthy and adds a nice balance to the cheese, and the diced walnuts add this really nice taste and texture.
