Pre-heat oven to 425°, lightly oil an 8 x 6 inch baking dish.
In a large pot of boiling salted water add the Gnocchi, remove as soon as the Gnocchi float (no more than 30 seconds) and drain well.
In a medium pot over medium heat melt butter, then add flour and salt, combine with a whisk, add milk slowly and continue to stir until thickened (but not too thick, if it becomes too thick add a little extra milk), stir in oregano,basil and pepper. Remove from heat. Stir in half the Fontal (or Gruyere cheese) and 1/2 the Parmesan cheese, then gently add the Gnocchi.
Place in baking dish, sprinkle with remaining Fontal cheese and Parmesan cheese, top with fresh thyme if desired. Bake for 3-5 minutes then broil for another 3-5 minutes. Let sit a couple of minutes before serving. Enjoy!
