Ingredients
  

Crispy Baby Bella Mushrooms

  • 8 ounces cleaned and sliced, baby Bella mushrooms you can use cremini or button mushrooms as well.
  • 1 1/2 tablespoons butter
  • 1/2 tablespoon olive oil
  • 1 teaspoon Tamari or soy sauce
  • 1 clove garlic minced
  • salt and pepper to taste
  • 1/2 tablespoon minced parsley

For the Crispy Mushroom and Onion Jam Grilled Cheese

  • 2 tablespoons butter
  • 8 slices rustic bread
  • 2 tablespoons mayonnaise
  • 1/2 cup onion jam click here for our recipe!
  • 1 batch prepared Crispy Baby Bella Mushrooms
  • 4 ounces Fontina cheese grated
  • 4 ounces Havarti cheese grated

Instructions
 

For the Crispy Baby Bella Mushrooms

  • Heat a large skillet over medium-high heat. Add the mushrooms to the dry, hot pan in a single layer. Stirring occasionally, allow the mushrooms to cook until they release all of their liquid and the liquid has evaporated from the pan. About 5 minutes.
  • Once there is no liquid left in the pan add the butter, olive oil, Tamari or soy sauce, and garlic to the cooked mushrooms. Continue to saute for about 2 minutes until the mushrooms are golden brown and there is no liquid left in the pan.
  • Turn off the heat, season with salt and pepper if desired then toss with parsley.

To assemble the Crispy Mushroom and Onion Jam Grilled Cheese

  • Heat a large skillet or griddle over med-low heat. For a griddle between 250-275°F will do the trick.
  • To prepare for assembly, combine the two types of grated cheese together.
    Spread a very thin layer of mayonnaise on one side of the slices of bread, this will be the side of the bread that comes in contact with the hot pan/griddle. Then spread 2 tablespoons of onion jam onto the opposite side of each piece of bread.
  • When the pan/griddle is preheated add 1/2 tablespoon of butter to the pan. Allow to melt then top the melted butter with a slice of bread, mayo side down.
    Repeat this process with the remaining butter and 3 slices of bread to the pan.
  • Once all 4 slices of bread are in the pan, onion jam side up, add about 1 tablespoon of shredded cheese on top of each one.
  • Layer on 1/4 of the Crispy Baby Bella Mushrooms then top with another 1-2 tablespoons of grated cheese.
  • Place the top piece of bread onto the sandwich, mayo side up.
    Cook for 3-5 minutes. low and slow, until a peek at the underneath reveals a golden brown exterior. Flip and continue to cook on the other side for another 2-3 minutes until golden. Serve immediately.
