Aromatic fennel, sweet shallots, and bitter chard (or kale) simmer in a creamy sauce enhanced with garlic and thyme topped with sharp aged cheddar cheese.
Prepare the greens by separating the stems from the leaves. Discard the tough, brown end of the stalk. Crush the stems with the side of a chef’s knife, and thinly slice the stems. Chop the greens, and set aside.
Step 3
In a large, deep, heavy skillet, melt the butter and olive oil over medium heat. Add the chopped stems, shallots, and thyme, and sauté for 3-4 minutes or until softened. Add the fennel, and continue to sauté for 5-7 minutes, adding the garlic during the last minute of cooking.
Step 4
Add the greens, stir well, turn heat to medium-low, and cover. Let cook for 4-5 minutes, or until greens are wilted. Uncover, and sauté until greens are cooked, and any water they have released has evaporated.
Step 5
Add the heavy cream, nutmeg, and salt, and stir to combine. Simmer gently for 2-3 minutes. Sprinkle the cheddar cheese evenly over the top of the gratin.
Step 6
Bake, uncovered, for 30-35 minutes, or until the cheese is lightly golden brown. You may broil for 2-3 minutes at the end if desired to crisp the topping.Cover to keep warm until serving.
