When I was looking for recipes for appetizers for our holiday party I immediately went for spinach dip, a charcuterie platter, and jalapeno poppers.  I wanted something a little heartier but I wasn’t sure what that was so I kept looking.

I finally decided on stuffed mushrooms.  Initially I was going to make sausage stuffed mushrooms but I’ve made those so many times before I wanted something a little lighter.  I remembered seeing vegetarian mushrooms crumbles and thought a vegetarian filling might be tasty but filling.

Ingredients:

  • Mushrooms
  • olive oil
  • Lion’s Main Mushroom Crumbles
  • spinach
  • scallions
  • garlic cloves
  • panko breadcrumbs
  • baby Swiss cheese
  • balsamic vinegar
  • salt
  • pepper
  1.  Preheat the oven to 375 degrees.
  2. Remove the stems from the mushrooms.  Wash the mushroom caps.
  3. Place the mushroom caps in a small bowl and toss with 1 tablespoon of olive oil.  Set aside.
  4. Heat the remaining olive oil in a large skillet over medium heat. Add the mushrooms crumbles and break apart. Cook for 8-10 minutes or until it is browned.
  5. Add the spinach, scallions, and garlic and cook for 2 more minutes.
  6. Add the breadcrumbs and half the baby Swiss and stir until the cheese just melts.  Drizzle with balsamic vinegar then sprinkle with salt and pepper. Remove from heat.

What makes the filling in these vegetarian stuffed mushrooms so amazing?  They are stuffed with Big Mountain Lion’s Main Mushroom CrumblesThe Lion’s Mane Mushroom Crumble is a combination of three types of mushrooms and it tastes delicious, is good for you, and is the perfect addition to any meal.

In addition to the mushroom crumbles there are breadcrumbs and baby Swiss cheese in the mixture.   Then the mushroom mixture is drizzled with balsamic vinegar to give it a sweet and tart flavor.   It really pairs well with the creamy Swiss cheese.

Is there any way to make this a vegan recipe?

Of course!  The only item that isn’t vegan is the baby Swiss.   You can either just eliminate the cheese all together or you can use a vegan cheese in place of it.   It tastes just as good without the cheese!

I’m not a fan of Swiss cheese.  Can I use something else?

Sure!  Mozzarella cheese is what is traditionally used so that’s a great choice but you can use any of your favorites.  I’d recommend cheddar, gouda, or Parmesan.

I’m making other things in the oven.  Can I make these in the Air Fryer?

Can you make them in the Air Fryer?  Yes.  Would I recommend it?   No.  I actually made them in the Air Fryer and while it worked, they were pretty dry and not nearly as good as they were when I made them in the oven.   So while you can air fry them, I wouldn’t recommend it. 

Can I make these ahead of time?

You can make the filling ahead of time and prep the mushrooms ahead of time.  Both of these can be done up to 24 hours in advance.  Just rinse and dry the mushroom caps after pulling off the stems.  Store the filling in the refrigerator after making. Then just put them together before baking.

For being a vegetarian stuffed mushroom these are surprisingly meaty.  My husband ate one and was trying to guess what I stuffed it with.  When I told him it was a mushroom crumble he was shocked!

These has a ton of flavor with a little bit of saltiness from the cheese and a sweet and tartness from the balsamic.  The mushrooms are earthy and all together it’s just a great bite.

I like to make stuffed mushrooms as a Game Day snack or as an appetizer because they are fairly easy to make, it’s something other than a dip, and they are pretty filling.  Make sure to give them a try today!
