Oyster Mushroom Rockefeller

This genius little dish was dreamed up by my good friend Michael Hughes. He did a version of it when he was the chef of a supper club dinner that I was lucky enough to attend. 


I love the play on words: oyster mushrooms stand in for oysters in this Rockefeller. Come on, it's awesome! Besides that, it tastes really great, and they are fun to eat. This dish would make the perfect appetizer for your holiday party. The rich spinach bumps up against the meaty mushroom. The whole thing is topped with crunchy parmesan and breadcrumb topping.


Oyster mushrooms can be found at Whole Foods and Fresh Market. However, to get the biggest and best (not to mention least expensive) mushrooms, it's best to seek out your local Asian foods market.


Oyster Mushroom Rockefeller
(makes a dozen)

2 tablespoons butter
1 tablespoon olive oil (more for drizzling)
12 large oyster mushroom caps (woody stems trimmed off)
salt and pepper
1/4 cup shallot
1 tablespoon garlic
splash of Pernod
1 tablespoon vermouth
1 tablespoon flour
1/2 cup whole milk (or cream)
5 ounces fresh spinach (blanched, squeezed dry, chopped)
1/2 cup parmesan
1 tablespoon bread crumbs
lemon slices
chopped parsley


In a 12-inch frying pan over medium heat, melt a tablespoon of the butter and add the olive oil. Once the oil has come up to temperature, sear the mushroom caps until lightly browned on both sides. This should take about 2 minutes per side. Remove mushrooms from the pan and set aside on a separate plate. Season them with salt and pepper to taste.


Into the same pan with the remaining oil and butter, add the shallot and garlic. Cook for a few minutes until the shallot has softened. Be sure to keep the mixture moving so the garlic does not burn. Add the Pernod and vermouth to the pan. Once the alcohol has evaporated, remove the shallot and garlic mixture, and set aside in a separate bowl.


Melt the remaining tablespoon of butter in the pan. Add the flour and whisk until fragrant. This should take about two minutes. Whisk in the milk making sure there are no lumps. Once the mixture starts to thicken, add the spinach and the garlic and shallot mixture. Check for seasoning. Add salt and pepper to taste.


Now mix the parmesan and breadcrumbs together in a separate bowl. Turn your oven on medium broil. You are now ready to assemble the dish. Gather 12 ceramic soup spoons. Into each place 1 tablespoon of the spinach mixture, one large oyster mushroom cap, a tablespoon of the parmesan mixture, and a drizzle of olive oil. Broil for four minutes or until browned. Keep warm in a low oven until ready to serve. Serve with lemon slices and chopped parsley.
