Ingredients

Instructions

  1. Cut a large onion in half, not cross-section.
  2. Remove the inside sections, leaving a cup two sections thick.
  3. Fill the onion shell with an egg or hamburger.
  4. Place on a bed of coals to cook until done.

Tips & Substitutions

For best results, choose a large onion that is firm and heavy. You can substitute the egg with cooked ground beef for a heartier option. Make sure to remove enough of the onion's inner sections to create a stable shell, but don't go too thin. Cooking over coals adds a smoky flavor, but you can also bake in an oven at 375°F until the egg is set. Consider pairing with a side of mixed greens.

Serving Suggestions

Serve the onion shell as a unique appetizer or main dish. It pairs beautifully with a fresh salad or grilled vegetables. For a complete meal, consider serving it alongside a side of Boiled Eggs or a refreshing cucumber salad. This dish is perfect for outdoor gatherings or barbecues, making it a fun addition to your summer menu.

Storage & Reheating

If you have leftovers, store the filled onion in an airtight container in the refrigerator for up to 2 days. To reheat, place it in the oven at 350°F for about 15-20 minutes or until warmed through, ensuring the egg is cooked properly. You can also microwave it, but be cautious not to overcook the egg.

Frequently Asked Questions

Can I use different types of onions for this recipe?

Yes, you can use sweet onions or even red onions for a different flavor profile. Just ensure they are large enough to hold the filling. Each type of onion will impart its unique taste, so feel free to experiment based on your preference.

What can I do if the onion shell breaks while cooking?

If the onion shell breaks, you can still salvage the dish by transferring the filling to a small baking dish and cooking it that way. Alternatively, wrap the onion in foil to help hold its shape while cooking. Just keep an eye on the cooking time as it may vary.

How can I add more flavor to the filling?

You can enhance the filling by mixing in herbs like parsley or chives, or even cheese for a richer taste. Consider adding spices or a splash of hot sauce to the egg for a kick. For more ideas, browse more Vegetarian recipes that can inspire flavor combinations.
