Savory Sweet Potato and Sage Soufflé
Serves: 10
Ingredients
- 4 lbs. sweet potatoes (Garnet yams), washed
- 3 Tbsp. olive oil
- 2 Tbsp. kosher salt
- 2 Tbsp. butter, plus 2 Tbsp. for buttering the baking dish
- ½ cup yellow onion, minced
- 12 sage leaves
- 4 Tbsp. all-purpose flour
- 1 cup cream
- 5 large eggs, separated
- 1/8 tsp. white pepper
- ¼ cup Parmesan cheese, grated
Instructions
- Preheat the oven to 375ºF.
- Place the sweet potatoes on a baking sheet. Rub with olive oil and 1 tablespoon of salt. Roast in the oven for around 1 hour or until fork tender. Remove from oven and allow to cool to the touch.
- Butter a 2-quart oval gratin dish and set aside.
- Meanwhile, in a sauté pan melt the butter. Add sage leaves and brown slightly, approximately 1 minute. Remove sage leaves, chop and set aside. Add onions to the pan and cook over low heat for 5 minutes or until tender. Add flour, stir and cook for 2 minutes. Add cream and whisk to combine. Remove from heat, add chopped sage and let cool.
- Peel the sweet potatoes and discard the skin, then push through a fine ricer or a mesh strainer. Set aside.
- Whisk egg yolks in a bowl and add cooled cream mixture. Stir to combine. Add sweet potato puree, 1 tablespoon kosher salt, white pepper and half of the Parmesan cheese. Stir thoroughly to combine.
- In the bowl of an electric mixer fitted with the whisk attachment, beat egg whites until medium firm peaks form. Using a rubber spatula, gently fold 1/3 of the egg whites into the sweet potato mixture. Repeat this step twice.
- Transfer to the buttered baking dish and sprinkle with remaining Parmesan cheese. Place on a baking sheet and bake for approximately 40 minutes or until evenly puffed and internal temperature reaches 160ºF. Carefully, remove from oven and serve immediately.
