Preheat your oven to 400℉

Heat the frying pan to high; add oil, and let it warm for a minute. If using a burger press, add a little oil to it now.

Add the mushroom to the pan. Press with either the back of a second cast iron, or the burger press, and press the mushroom while searing, 1-2 minutes. Flip the mushroom, and top again with the pan or press, searing for an additional minute or two.

With the mushroom seared on both sides, if you're using cast iron you can season the mushroom in the pan and put directly in to the oven. If not, transfer to a lined baking sheet before adding the spice and sauce.

Bake the mushroom for 15-20 minutes, until the sauce caramelizes on top and the edges begin to burn a bit.

Serve with roasted vegetables or on a slice of garlic bread like a steak sandwich. Enjoy!
