🔥🧅 Firecracker Bacon Cheddar Cheeseburger Stuffed Onion Bombs

These are big, bold, and messy in the best way: whole onions hollowed out and stuffed with bacon-cheddar cheeseburger filling, then baked (or grilled) until caramelized and juicy with a spicy “firecracker” kick.

🧾 Ingredients (4 large onion bombs)

Onion base

4 large yellow onions (firm, similar size)
1–2 tbsp oil or melted butter
Salt

Cheeseburger filling

500g ground beef (80/20 preferred)
6–8 strips bacon, cooked and crumbled
1 cup cheddar cheese, shredded (plus extra for topping)
1 small onion (from trimmings), finely chopped
2–3 cloves garlic, minced
1 egg (helps bind, optional)
½ cup breadcrumbs (optional, for structure)
1 tsp salt
½ tsp black pepper
1 tsp paprika or smoked paprika
1 tsp chili flakes or cayenne (this is your “firecracker” heat)

Firecracker sauce (optional but recommended)

2 tbsp hot sauce
1 tbsp ketchup
1 tbsp BBQ sauce
1 tsp honey

👨‍🍳 Instructions

1. Prep the onions

Peel onions and trim top/bottom slightly so they stand flat.
Cut a deep hollow in the center (leave 2–3 outer layers intact).
Save the scooped onion for the filling.
Brush outside with oil and sprinkle with salt.

2. Cook bacon

Fry bacon until crisp.
Crumble and set aside.

3. Make the filling

In a pan, sauté chopped onion + garlic until soft.
Add ground beef and cook until browned.
Stir in salt, pepper, paprika, chili flakes.
Mix in bacon and let cool slightly.
Add cheddar cheese + egg + breadcrumbs (if using).
Optional: stir in firecracker sauce for extra punch.

4. Stuff onions

Fill each onion tightly with the meat mixture.
Press gently so they hold shape.
Top with extra cheddar.

5. Bake

Preheat oven to 190°C (375°F).
Place onions in a baking dish (they should stand upright).
Cover loosely with foil.
Bake for 45–60 minutes, until onions are soft.
Remove foil for last 10 minutes to brown cheese.

6. Finish

Let rest 5–10 minutes before serving.
Spoon any juices over the top.

💡 Tips for best results

Choose large, similar-sized onions so they cook evenly.
Don’t hollow too much or they’ll collapse.
Pre-cooking bacon adds deeper smoky flavor.
Resting after baking keeps the filling firm.
