Mushrooms are pretty much the perfect appetizer — a hand-held, delicious edible little vessel for all sorts of  delicious things! No need for toothpicks or even a plate…..just a free hand, and maybe a napkin. It seems people either love mushrooms or hate them.  Back in the day, I wouldn’t touch a mushroom.  I’d pick them off a pizza, leave them off a burger and snarl my nose at them in soup.  I’m not sure when the turnaround happened really, probably as a young adult everything mushroom began to change.  Now, I can’t get enough; raw mushrooms in my salad, I can barely eat a steak without sautéed mushrooms, and best of all…….i love them stuffed! oh how times change.

When my friends at Daisy Brand asked me to come up with a recipe using Daisy Sour Cream, Cheesy Mashed Potato Stuffed Mushrooms was the first thing that came to mind. If you love everything about a loaded baked potato, then you must try this appetizer.  You get all that cheesy, sour cream and flavorful potato goodness in a small, tasty package.  It’s a great way to use up leftover mashed potatoes, too! 

Cheesy Stuffed Mushrooms are easy to make

Now here’s the secret…..you can use leftover mashed potatoes or even instant mashed potatoes.  But, to get them extra creamy and velvety you will want to add a few squeezes of sour cream. Daisy Squeeze is the key to luxurious mashed potatoes. It’s quick and easy to add without dirtying measuring spoons so there’s less to clean up and more time to eat!

Add cheddar cheese, green onion, chives and spices and you’re good to go.
