Brian Alberg's Mushroom Conserva

Mushroom Conserva


Created by Brian Alberg, Executive Chef and Director of Food & Beverage

at The Red Lion Inn, Stockbridge, MA


¼ cup olive oil

3 cloves garlic, sliced

2 shallots, sliced

2 lbs mushrooms, sliced – recommended mushrooms include Shiitake, Oyster and Maitake (also known as Hen-of-the-Woods.) If using Portobello, remove the gills by de-stemming and scooping out

1 sprig of rosemary

3 sprigs of thyme

4 T sherry vinegar

3 ears sweet corn on the cob, blanched and de-kerneled

Kosher salt, to taste

1 1/2 cups olive oil for topping off the jars


Place a large skillet on medium heat. Add ¼ cup of olive oil to the pan and heat until simmering. Add garlic and shallots and cook for about 3 minutes until translucent. Add mushrooms, rosemary and thyme and simmer for 20 minutes. Deglaze the pan with sherry vinegar and simmer another 10 minutes. Add in blanched sweet corn, season with salt to taste and remove from heat. Lay out cooked mushroom mixture on a sheet pan to cool. After about a half hour (once the mixture has reached room temperature,) place in sealed quart containers. Top each container with the remaining olive oil so the mixture is completely covered and refrigerate. (For catered events at the inn, we use pint-sized mason jars to store the Conserva. When serving, we bring the Conserva up to room temperature and serve directly out of the jar at the table.)

The Conserva will last about two weeks in the refrigerator because the mixture is slightly pickled and preserved in olive oil. Recipe makes about 6 ½ cup portions.
