You'll need a frypan, oven tray and the oven preheated to 180 C/ 350 F
First peel the outer skin from the mushrooms and remove the stalk. Finely chop these and set them aside.
Put the mushrooms onto the lined oven tray and drizzle with 2 Tablespoons of the oil or melted butter and a grinding of pepper. Bake for 15 minutes or until starting to soften and release some juices. Set aside
Cut the onion and slice the ham. Then heat a fry pan to medium heat, add the oil or butter and the onion and mushroom trimmings and gently sauté till they are soft.
Take off the heat and cool down. when cool to touch add the Black Garlic Mayonnaise, Dijon and ham and stir well to combine.
Pile the filling mixture into the mushroom cups ( these will probably go flat- that's OK). Then top with a slice of both cheeses then sprinkle with a little smoked paprika. You can store these at these for later now if you like)
Pop into the oven and bake till bubbling, approximately 10-15 minutes depending on your oven ( they could also go under a grill or broiler)
Eat as an appetiser or entrée or use smaller mushrooms for a canapé / small party bite.
These are great both at room temperature or refrigerated and reheated for up to two days later
