Preparing these stuffed white button mushrooms can be fun and entertaining. They may be helpful in enticing extra hands into the kitchen for family time or a good teaching moment with your kids. The adults can chop and saute, and the younger can spoon and stuff.

Here are a few helpful facts about cooking with white button mushrooms . . .

  • Transfer the mushrooms to a paper bag and keep them in the refrigerator so they can breathe and not turn mushy, theyll last longer than in their original plastic containers.
  • Or, place them on a tray and cover with a damp paper towel before refrigerating.
  • Always wash the mushrooms right before using them.
  • If you arent concerned about these little buttons absorbing water, you can give them a bath in cold water, turning them about, so the dirt falls to the bottom of the water-filled bowl.
  • Or, clean the mushrooms with a damp paper towel or brush, like a toothbrush or mushroom brush.

In this recipe, well clean them with a damp paper towel, trying to avoid any added water absorption because we want them to crisp up some in the oven. A good tip is to purchase the smaller, but not too small, mushrooms for a single crispy bite.

Next, remove the stems and chop, chop, chop!

You can twist the stem off or take a small, sharp knife and carve them out. Dice finely the mushroom stems, onion, and celery, so they are easier to stuff into the caps.

Now, its time to melt some butter and coat the mushroom caps tossing and salting them generously on both sides.

Remove the caps and saut the chopped onions, celery, and garlic in the melted butter until they are soft. Add the mushrooms and cook some more before stirring in the spinach, salt, and red pepper flakes. Cook until the spinach is wilted.

Fill the caps and place them in a bacon dish. You can sprinkle with your favorite cheese if you like. I used parmesan here, but if you like the cheese to melt and ooze down the mushroom, use a good melting cheese like Mexican Four Cheese.

Bite-sized mushrooms help bake them into a crispier bite.
