Ingredients for the stuffed mushrooms

How to make Philly cheesesteak stuffed mushrooms

First place four Portobello mushroom caps on a lined baking sheet.

Drizzle a little olive oil over top along with a sprinkle of kosher salt and pepper.

Then place them in a 400 degree oven for about 10 minutes.

Seasoned Portobello mushrooms before cooking

As the mushrooms are cooking by themselves in the oven, set a skillet over medium heat and once hot add some olive oil, diced onion, diced green pepper, kosher salt, and pepper.

Cook this for about four to five minutes stirring a few times.

Next, add some garlic, the shaved beef, and some Worcestershire sauce.

Cook this about 3 to 4 minutes stirring occasionally and breaking apart the shaved beef with the spatula.

Then remove from heat and stir in 1/2 cup of either queso or Nacho cheese sauce to make it extra creamy.

Taste for seasoning and add more kosher salt and pepper if needed.

Adding steak and seasoning to the Peppers and onions

By the time the filling is done the mushrooms should be cooked.

Now it’s time to stuff them!

Before stuffing the mushrooms get a paper towel and soak up any moisture that is in the mushrooms.

Ready to stuff the mushrooms.

Then stuff the mushrooms with the delicious filling.

We had just a little bit of filling leftover so it was nice to snack on while the mushrooms finished cooking.

Stuffed mushrooms before adding cheese

Top each with a slice of provolone cheese and then back into the oven for about another 8 to 10 minutes.
