Ingredients

  • 8 medium onions
  • 1 cup bread crumbs
  • 1/2 teaspoon salt
  • 1/2 teaspoon paprika
  • 2 tablespoons butter
  • 1 cup chopped pecans
  • 1 tablespoon flour
  • 1 cup milk

Instructions

  1. Peel the onions and boil them whole in salted water until tender.
  2. Cool the onions, then remove the centers, chop the removed onion flesh, and combine with bread crumbs, chopped pecans, salt, and paprika.
  3. Stuff the onion shells with the prepared mixture.
  4. Make a white sauce by melting butter, then stirring in flour, milk, and salt until smooth and thickened.
  5. Pour the white sauce over the stuffed onions placed in a buttered baking dish.
  6. Bake in a preheated oven at 350°F (175°C) for 30 minutes.

Tips & Substitutions

For a variation, consider adding grated cheese to the stuffing mixture for extra flavor. If you want a gluten-free option, use gluten-free breadcrumbs or crushed nuts instead of regular bread crumbs. Make sure to thoroughly boil the onions to ensure they are tender enough to scoop easily. This dish pairs beautifully with American recipes like Oglethorpe Corn Bread.

Serving Suggestions

Serve the casserole onions as a flavorful side dish at your next gathering. They pair well with roasted meats or a fresh salad to balance the richness. Consider offering a tangy dipping sauce on the side for added flavor. This dish complements hearty meals like Double Chocolate Shortcakes if you're planning a full dinner spread.

Storage & Reheating

Store any leftovers in an airtight container in the refrigerator for up to 3 days. To reheat, place the casserole in a preheated oven at 350°F (175°C) for about 15-20 minutes, or until heated through. You can also microwave individual portions for a quicker option, but the oven will retain the texture better.
