<p>Seven Onion Soup </p>
<p>Ingredients
4 tablespoons unsalted butter
4 slices bacon, chopped
1 1/2 cups sliced yellow onions
1 1/2 cups sliced red onions
1 1/2 cups sliced white onions
1 cup sliced shallots
1/2 teaspoon salt
1/2 teaspoon freshly ground black pepper
1 bay leaf
1/2 teaspoon dried thyme
1 cup sliced leeks, bottoms only, well rinsed in several changes of water
1 cup sliced scallions (white parts only)
1/3 cup all-purpose flour
2 quarts chicken stock
1 cup cream
Salt and pepper
3 teaspoons snipped chives, for garnish
Shaved Parmesan, for garnish </p>
<p>Directions
In a large skillet, melt the butter over medium-high heat. Add the bacon and cook until the fat is rendered and the bacon is crisp, about 7 minutes. Remove the bacon with a slotted spoon, drain on paper towels, and set aside for garnish. </p>
<p>To the fat remaining in the pan, add the yellow, red, and white onions, shallots, salt, pepper, bay leaf, and thyme and cook, stirring, until very soft and starting to caramelize, 8 to 10 minutes. Add the leeks and scallions and cook until soft, 3 to 4 minutes. Dust flour over, and stir and cook until flour turns light golden. Add the stock and bring to a boil. Reduce the heat and simmer uncovered for 45 minutes, stirring occasionally. Add the cream, stir well to incorporate, and cook for 15 minutes. </p>
<p>Remove the bay leaf and pulse soup with an immersion blender. Return to the pot, stir to combine, and heat gently. </p>
<p>Divide the soup into bowls and garnish each serving with bacon, chives, and a little shaved Parmesan.</p>
