Bacon Cheddar Onion Bombs with Sweet Barbecue Glaze Step-by-step instructions

Before you start

Before beginning, preheat the oven to 400°F (204°C) and line a large rimmed baking sheet with parchment paper or aluminum foil for easy cleanup. Set up a clean workstation with a sharp chef's knife, a cutting board, and a mixing bowl.

Carefully peel the outer paper layers off the onions, cut them in half crosswise, and gently separate the outer layers to form sturdy hollow shells. Measure out the ground beef, beef seasoning, cheddar cheese cubes, bacon slices, and barbecue sauce so everything is ready to assemble.

Instructions

Preparing and Stuffing the Onion Shells

1. 1Prep the Onion Shells
   Peel the yellow onions and slice them in half crosswise. Carefully hollow out the center of each half, leaving the outer two to three layers intact to create four sturdy onion cups. Save the discarded inner onion layers for future cooking use. Set the prepared onion shells aside on your clean work surface.
   Look for The onion shells should be uniform, sturdy, and free of any deep cracks.
   Tip Use a spoon to gently scoop out the center layers without puncturing the outer walls.
2. 2Season the Ground Beef
   In a medium mixing bowl, combine the ground beef and beef seasoning. Use your hands to gently mix the seasoning into the meat until evenly distributed throughout, being careful not to overwork the beef so it remains tender.
   Look for The seasoning should be fully integrated into the meat mixture.
   Tip Overmixing ground beef can make it dense, so mix just until the seasoning is incorporated.
3. 3Stuff the Onion Shells
   Divide the seasoned ground beef into four equal portions. Press a portion of beef into each hollowed onion shell, inserting a solid cube of cheddar cheese into the very center of the beef so it is completely enclosed and sealed within the meat.
   Look for The cheese must be fully sealed inside the beef mixture.
   Tip Ensure no cheese is exposed to prevent it from leaking out during the baking process.

At the end of this phase, the seasoned ground beef should be thoroughly mixed with the seasoning, and the hollowed onion shells should be packed tightly with the meat mixture, centering a solid cube of cheddar cheese inside each bomb. The stuffed onions should look neat, compact, and completely filled to the brim.

Wrapping and Baking the Bombs

4. 4Wrap with Bacon
   Wrap two slices of bacon tightly around each stuffed onion bomb, covering the exposed beef and wrapping snugly around the onion shell. Secure the loose ends of the bacon with wooden toothpicks if necessary to keep them in place.
   Look for The bacon should wrap snugly around the entire onion bomb.
   Tip Stretch the bacon slightly as you wrap to ensure a tight, secure fit that won't unravel.
5. 5Bake the Onion Bombs
   Place the wrapped onion bombs on a parchment-lined baking sheet. Bake in the preheated oven at 400°F (204°C) for 35 to 40 minutes, until the ground beef is cooked through to a safe internal temperature of 160°F (71°C) and the bacon is crispy.
   Look for The bacon should look deeply golden and crispy on the outside.
   Safe temperature 160°F (71°C) internal temperature (ground meat)
   Tip Use an instant-read thermometer to check the temperature at the center of the meat.

At the end of this phase, the bacon wrapped around the onion bombs should be deeply browned, crispy, and clinging tightly to the onions. The onions will have softened and turned translucent, and you should hear a lively sizzling sound as the bacon fat renders onto the baking sheet.

Glazing and Caramelizing

6. 6Glaze with Barbecue Sauce
   Brush the glossy barbecue sauce generously over the crispy bacon exterior of each onion bomb. Return to the oven for an additional 5 minutes until the glaze is bubbling, sticky, and beautifully caramelized. Remove from the oven and let rest for 5 minutes before serving.
   Look for The glaze should be bubbling, sticky, and slightly darkened on the edges.
   Tip Watch closely during the final minutes to prevent the sweet sauce from burning.

At the end of this final phase, the barbecue sauce glaze should be bubbling, glossy, and slightly darkened, clinging to the crispy bacon.

The cheese inside will be completely molten, occasionally bursting through the top in a beautiful, gooey display, and the aroma of smoky bacon and sweet caramelized onions will fill the room.

Common mistakes

One common mistake is wrapping the bacon too loosely around the onion shells. As the bacon cooks, it shrinks, and if it is not secured tightly, it will unravel and slide off the onion, losing the protective barrier and smoky flavor.

Another error is using onion shells that are too thin or cracked, which can cause the seasoned beef and cheese to leak out during baking. Finally, do not rush the baking process at a temperature that is too high, as this will burn the bacon before the ground beef is cooked safely to the center.

How to tell it’s done

To ensure the onion bombs are perfectly cooked and safe to consume, insert an instant-read meat thermometer into the very center of the beef filling. The ground beef must reach a safe internal temperature of 160°F (71°C).

At this point, the bacon on the exterior should be beautifully crisp and golden-brown, the onion shell tender enough to be easily pierced with a fork, and the cheddar cheese in the center completely melted and molten. Let the bombs rest for a few minutes before serving to allow the juices to redistribute.
