Cook 2 pounds carrots (cut on an angle into 1 1/2-inch pieces) in salted boiling water until crisp-tender, 8 to 10 minutes; drain. Heat 1/4 cup olive oil in a large skillet over medium heat. Add 1/4 cup sliced almonds, 3 sliced garlic cloves and 1/4 teaspoon red pepper flakes; cook, stirring, until toasted, 4 to 5 minutes. Remove with a slotted spoon to a bowl. Add the carrots, 2 tablespoons each maple syrup and white wine vinegar and 1/2 teaspoon kosher salt to the skillet. Cook over medium-high heat, stirring, until glazed, 4 to 5 minutes. Toss the almond mixture with 2 tablespoons each chopped chives and parsley; season with salt. Sprinkle over the carrots.
