Oyster Mushrooms Rockefeller

This is a vegan take on classic oysters Rockefeller, created at the New Orleans restaurant Antoine's in 1899 and named after John D. Rockefeller, America's first billionaire, because of its very rich sauce. We've given instructions on how to make it in a single pan, but you can also divide the ingredients among small ramekins for individual servings.



Ingredient Line: 
2 12-oz. pkg. fresh oyster mushrooms, tough parts of stems removed
Ingredient Line: 
4 Tbs. olive oil, divided
Ingredient Line: 
2 lb. baby spinach
Ingredient Line: 
½ cup vegan mayonnaise
Ingredient Line: 
½ cup chopped fresh fennel
Ingredient Line: 
2 tsp. Dijon mustard
Ingredient Line: 
2 Tbs. chopped shallots
Ingredient Line: 
2 cloves garlic, minced (2 tsp.)


1. Preheat oven to 400°F. Spread mushrooms in bottom of baking dish or baking sheet.

2. Heat 1 Tbs. oil in large skillet over medium-high heat. Sauté half of spinach 1 to 2 minutes, or until wilted, tossing occasionally. Remove from pan with tongs. Add 1 Tbs. olive oil to pan, and repeat with remaining spinach. Spread wilted spinach atop mushrooms in baking dish.

3. Whisk together remaining 2 Tbs. oil, mayonnaise, fennel, mustard, shallots, and garlic in small bowl. Spread sauce over spinach until well covered.

4. Bake 15 minutes, or until sauce begins to brown. Set oven to broil. Place baking dish under broiler, and broil 2 to 3 minutes, or until brown and bubbly. Serve as casserole, or spoon servings onto plates.

Comments on this Recipe

I was shocked at really how good this was!

I was pleasantly surprised by this recipe and will definitely make it again. Its an easy weeknight dish to make. I do recommend sauteeing the veggies first though and next time I will eliminate the olive oil in the mustard/mayo mixture (i thought it created too much excess liquid). It would be easy to substitute the spinach w/ kale, swiss chard or other greens. This would be great w/ grated cheese on top!


this is so good, i cooked the shallots and fennel slightly and added pernod. Cooled and then mixed in the mayo topping.

I've made this recipe several times because it's so good. Be sure not to skimp on the spinach.

It appears the spinach is the bottom layer - not spread on top of the mushrooms. Or was the casserole up-ended for serving as pictured?

This recipe is a keeper , one change i did , was I had enoki mushrooms on hand to try out , chopped up with onion's fried in some gee and I used more fennel and less maio. Fantastic dish

Amazing! I agree, don't skimp on the spinach.

what can i use instead of the vegan mayo?
