This Mushroom Swiss May Look Like A Regular Grilled Cheese But We’ve Added Something That Any Adult Would Beg For

You're going to need room temperature butter because it's much easier to work with for sandwiches. To add in some healthy greens you can use kale or spinach or even sliced asparagus.

Ingredients To Gather:

3 teaspoons vegetable oil, divided
½ large onion, sliced into half circles
5 ounces baby portabella mushrooms, sliced
1 teaspoon kosher salt, divided
½ cup freshly shredded Swiss cheese, divided
4 thick slices of bread (Italian, French, sourdough, or your favorite)
1 tablespoon unsalted butter, room temperature

Step By Step Directions To Follow:

In a skillet over medium-high heat, add 2 tsp. of vegetable oil. When oil is hot, add the onions and ½ tsp. of salt and cook until dark brown in color and softened. Halfway through, you’ll want to turn down the heat to medium heat. Caramelizing onions will take about 20-30 minutes. Add water to the caramelizing process if the pan is too dry.
When the onions are caramelized, transfer to a bowl. Add the remaining 1 tsp. of vegetable oil to the skillet and add the mushrooms and remaining ½ tsp. of salt. Cook the mushrooms until softened, about 5 minutes. Remove from skillet.
Preheat broiler in oven.
Butter both sides of bread. Place bread on to a baking sheet and place under broiler for about 1 minute each side. Carefully remove bread from baking sheet and on an even surface, begin to assemble your sandwich.
Place caramelized onions on one slice of bread, then the mushrooms on top, then ¼ cup of shredded Swiss cheese. Gently place on baking sheet. Repeat with another slice of bread. Place baking sheet into the oven for 1-2 minutes until cheese is melted.
Remove from oven and gently press down the remaining two slices of bread on top.
