To make the béchamel sauce, melt the butter in a small sauce pan. Once melted, add the flour, and cook the flour on medium heat, stirring for a few minutes. Once the flour is cooked through, add in the milk, and continue to stir until you have a nice thick sauce. Season with salt and pepper, and set it aside.
To a small skillet, add the half tablespoon of butter, and let that melt. Once melted, add in the mushrooms, and cook for about ten minutes. Add in the soy sauce, toss, and season with a pinch of salt and pepper.
Preheat your oven to 425 degrees.
Take the slice of French bread pizza, and slather on the béchamel sauce, coating from edge to edge. Coat the sauce with the cooked mushrooms, then top with the grated parmesan cheese.
Place into the oven, and cook for about 25 minutes, or until the sauce is lightly browned.
Remove from the oven, let cool for about 5 minutes, then dig in.
As I love a pepperoni or Italian sausage French bread pizza, this mushroom French bread pizza was amazing. The cremini mushrooms added a light meaty flavor that was perfectly balanced with the creamy béchamel sauce. So if you are looking for an easy French bread pizza to make, give this one a try.
