Mediterranean Stuffed Mushrooms

There’s something about this time of year that has us appetizer-obsessed.

Whenever there’s a free minute, we’re poring over magazines and websites looking for the perfect appetizer – something easy, but impressive. Something quick, but looks like you spent all afternoon in the kitchen, channeling your inner Barefoot Contessa. Something that’s not the same old spinach dip in a bread bowl.

Well, we’ve found it. This year, we’re shaking things up a little with our Mediterranean Stuffed Mushrooms. They’re the perfect balance between fancy and friendly, and they are going to be the hit of the party.

We’ve had a few stuffed mushrooms in our time, but these are our new favorites. The crispy parmesan on top is just a hint at the goodness inside. These mushrooms are stuffed with spinach, sun-dried tomatoes, pine nuts, onion, garlic, balsamic, oregano, and you can bet your little black dress there’s oats in there.

You know how some stuffed mushrooms look great, but sometimes can get a bit soggy? It’s no wonder – mushrooms are 90% water! Just a half-cup of quick oats stirred into the stuffing keeps the mushroom juices from watering down the filling, preserving all of those bold Mediterranean flavors and preventing the mushrooms from getting too soggy. (Pro tip: keep this in mind whenever a recipe calls for bread crumbs to bind a wet mixture.)

Surprisingly, these stuffed mushrooms are not difficult to make, considering how elegant they look. It won’t take you much longer to make a batch of them than to stuff a bread bowl with spinach dip.

The filling comes together in a snap, so you can afford to take an extra couple minutes to remove the gills from your mushroom caps. Gills? Yeah, you know, the gills; those frilly brown bits on the inside of the mushroom cap. Get rid of those gills and make more room for the delicious stuffing!

When you are ready to stuff your beautiful mushroom caps, pile them high and don’t skimp on the parmesan cheese. And get ready for your calendar to fill up – these are definitely going to get you invited to more parties once the word starts getting around.
