Onion and Poppy Seed Quick Bread

"Instead of mashed potatoes or noodles, try serving this buttery poppy-seed-and-caramelized-onion bread with your next beef stew or soup. Or try it in a fancy grilled cheese sandwich using two thin slices of bread and some fontina cheese. Special equipment: You will need a metal 9-by-5-inch loaf pan for this recipe. Loaf pans can be purchased at most cooking supply stores and at many large grocery stores. Game plan: You can also use this recipe to bake savory muffins instead of bread—just use a standard 12-well muffin pan. Coat the wells with butter and bake the muffins at 350°F until a toothpick inserted into the center comes out clean, about 20 to 25 minutes. Let the muffins cool for 10 minutes, then remove them from the pan and finish cooling on a wire rack. This recipe was featured as part of our 5 Savory Quick Breads for Fall Baking...."
