This vegetarian version of oysters Rockefeller is out of this world!! I was not sure if you could substitute nut milk in a béchamel sauce, so this dish is not vegetarian. I served it on toasted sourdough – so good! It comes together pretty quickly so it is doable on a weeknight.
- 3 tbsp butter or vegan butter
- 1 tbsp olive oil (more for drizzling)
- 1 lb oyster mushrooms, broken into pieces if they are large12 large
- salt and pepper
- 1/4 c shallot, minced
- 3 cloves garlic, minced
- splash of Pernod
- 1 tbsp vermouth
- 1 tbsp flour
- 1/2 c whole milk
- 8 oz fresh spinach
- 1/2 c parmesan, grated
- 1/4 c bread crumbs
- 1/4 c chopped parley
- lemon slices
- 4 pieces of toasted bread
In a 12-inch frying pan over medium heat, melt 1 tbsp butter and olive oil. Once the oil has come up to temperature, sear the mushroom caps until lightly browned on both sides, season with salt and pepper. Remove from pan.
Add 1/2 tbsp of butter to the pan, stir in shallot and garlic. Cook for a few minutes until softened. 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 butter in the pan. Add the flour and it starts to brown a little. 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, cook until spinach starts to wilt.
Mix the parmesan, parley and breadcrumbs together
Turn your oven on medium broil.
Grab a 8×8 baking dish, spread the spinach mixture on the bottom, top with mushrooms and breadcrumbs.
Broil for 3 – 4 minutes or until browned.
Spread on toast and serve.
Serve with lemon slices.
