Preheat oven to 425 degrees F.
Lay bacon out on a roasting pan in a single layer and bake for 10 minutes until just crispy - remember they will be going back into the oven with the oysters so you don't want to finish the bacon just yet. While the bacon is cooking, place the butter, garlic, shallots
, bell pepper, celery
, lemon zest and juice, oregano
, thyme, and chili flakes in a food processor
until well combined, but still has texture. Season with salt and pepper, to taste.
Remove bacon from oven and cut up into pieces. Lay oysters in their half shells out on a large roasting pan in a single layer (you can use rock salt
or a sheet of crumpled foil to steady them). Place 1 tablespoon of the casino butter mixture on top of each oyster and place a piece of bacon on each. Bake oysters
in the hot oven until bubbly, approximately 10 to 12 minutes. Finish with finely chopped, fresh flat-leaf parsley and serve.
