Large Portobello Mushroom (1)
on a parchment-lined baking sheet. With a spoon take out the core, and keep the stem aside, next remove the gilets.
Olive Oil (as needed)
on top of the mushroom, and set it aside. Then roughly chop the mushroom stem and reserve for later.
In a frying pan over medium-high heat, add
Hillshire Farm® Smoked Sausages (4)
, turn them every minute, and let them cook until they are cooked through and slightly browned. It takes about 1-2 minutes. Once done, remove from the frying pan and set aside.
In the same pan, keep the juice that is left behind from the sausages, and add the chopped-up mushroom stem together with the
White Onion (1/2)
. Cook for 3-4 minutes, or until the onions are translucent.
Meanwhile, chop the sausages, and transfer them to the pan. Turn off the heat and mix everything together.
Next, take the pan off the heat, sprinkle
Mozzarella Cheese (1/2 cup)
on top, and mix to combine.
Carefully spoon the mixture into the mushroom cap.
Lastly, sprinkle more cheese on top.
Place the tray into the preheated oven and bake at 450 degrees F (230 degrees C) for about 25 minutes, until it's baked all the way through.
Remove from oven and serve immediately. Slice to serve. Enjoy!
