Agreed. Good stuff and can be made ahead. Like you, I sometimes use the stick blender
to puree the onions. Sometimes I also add some fresh thyme leaves at the end of cooking the onions.
Homemade Gravy (Makes 3 cups)
1/4 pound (1 stick) unsalted butter
1 1/2 cups chopped yellow onion (2 onions)
1/4 cup all-purpose flour
1 teaspoon kosher salt
1/2 teaspoon freshly ground black pepper
2 cups chicken stock, preferably homemade, heated
1 tablespoon Cognac or brandy
1 tablespoon heavy cream (optional)
In a large (10- to 12-inch) sauté pan, cook the butter and onions on medium-low heat for 12 to 15 minutes, until the onions are lightly browned. Don’t rush this step; it makes all the difference when the onions are well cooked.
Sprinkle the flour into the pan, whisk in, then add the salt and pepper. Cook for 2 to 3 minutes. Add the hot chicken stock and Cognac, and cook uncovered for 4 to 5 minutes, until thickened. Add the cream, if desired, and serve.
