VEGETARIAN STUFFED MUSHROOMS

I was, and still am, not a fan of mushrooms. But everyone I love and care about eats them so I put on my big girl pants and make them. Every so often…

These stuffed mushrooms are a great appetizer for a gathering, the first course for an elegant dinner party, or a delicious and earthy side dish for any meal.

If you are looking for a main dish, you can certainly take this recipe and just make it for 1 or 2 full size portobello caps.

Because the recipe is vegetarian, it’s a great meatless meal!

HOW DO YOU MAKE STUFFED MUSHROOMS NOT WATERY?

When using fresh ingredients, like the spinach, be sure to drain everything first. You can also roast the mushrooms caps for a few minutes upside down before stuffing them.

ARE STUFFED MUSHROOMS VEGAN?

You can make these vegan by substituting the cheese for vegan cheese.

HOW LONG DO UNCOOKED STUFFED MUSHROOMS LAST?

If you want to stuff them early, they will last a 2-3 days in the fridge before cooking them.

CAN YOU FREEZE STUFFED MUSHROOMS?

Yes, you can but you will want to freeze them before you cook them. Fill the mushrooms and then freeze for up to 3 months.

ARE THEY GLUTEN FREE?

If you use a gluten free version of the panko bread crumbs, then they are.

CAN YOU USE REGULAR SIZED MUSHROOMS?

Yes! Just make the filling and stuff them in large mushrooms caps. You might need to add in a few small chopped mushrooms to make more filling.

HOW TO CLEAN MUSHROOMS

Do not soak the mushrooms as they will absorb all the extra water. Instead, take a damp paper towel or cloth and gently wipe off the caps. If that takes too long, you can spray them with water over a strainer and then dry quickly.

CAN YOU MAKE THEM IN ADVANCE?

You can clean the mushroom caps, store them in a brown paper bag in the refrigerator. Make the filling and store as well. Strain the oil and store. Then I would stuff right before baking.

HOW TO STORE LEFTOVERS

Store any leftover stuffed mushrooms, if there are any, in the refrigerator for up to 3 days. Reheat in the oven for best results.

TAPAS TIPS & TRICKS

  • clean the mushrooms with a damp paper towel
  • skip the cheese to make it vegan
  • pick uniform size mushrooms so they coo evenly.
  • larger mushrooms may need to cook for up to 20 minutes.

I'm with you on the mushroom aversion. I used to detest those babies, but we're friends now. My pallet grew up, I think. In fact, I LOVE them! This is going on my list to make for a happy hour I'm hosting. I can taste them now :)
