The caramelized onions
1 ½ lb sliced onions
1 T butter
1 T olive oil
¼ tsp salt
The mushrooms
1 ½ -2 lb mixed mushrooms: shiitake, oyster,
lion’s mane, portabella, any combination
1 T butter
1 T olive oil
¼ tsp salt
The béchamel
3 cloves garlic, chopped
½ c. port, dry sherry, or broth
pinch of dried thyme and red pepper flakes
1 ½ T flour
1 T butter
1 ½ c warmed milk
Drop biscuit topping
2 c flour
1 tsp baking soda
2 tsp baking powder
1 tsp salt
4 T cold butter
½ c asiago or hard cheese, grated
1 1/3 c buttermilk
Start with the onions. By the time you’ve completed the other steps, the onions will be ready to incorporate.
Caramelize the onions: Heat the butter and oil in a large sauté pan and add the onions, sprinkling with salt. Lower the heat and sauté frequently while the onions soften and turn color. Within 45 minutes to an hour, the onions should be totally soft, dark gold and sweet. Adjust the salt and add a grind of pepper.
Saute the mushrooms: Meanwhile, heat the oil and butter for the mushrooms. Add the mushrooms and salt, reducing the heat after the mushrooms start to release liquid. Add the thyme and a dash of red pepper flakes or black pepper. Stir occasionally until mushrooms are soft and just a little liquid is left. Add the wine or broth, and sauté until a rich syrup remains. Adjust seasoning to taste.
Make the béchamel; Heat 1 T butter and add the 1 ½ T flour, cooking until bubbly. Add the 1 1/3 c. of warmed milk a little at a time, stirring after each addition to make smooth. Cook a few more minutes after the last addition until the mixture is the consistency of medium thick gravy.
Combine the mushrooms, the onions and béchamel and pour into a buttered casserole or gratin dish.
Make the biscuits: Cut the butter into the flour, salt, baking powder and soda. Stir in the grated cheese. Add the cold buttermilk and lightly combine. Drop evenly over the top of the filling; I use 1/3 c scoop which makes 9 biscuits over the top of a 9 inch square, 3 ½ inch deep gratin pan.
Bake at 400° for 25-30 min.
