Ingredients
For the Onion Bombs
2 large sweet onions
1 pound ground beef (80/20 preferred)
8 slices bacon
1 cup shredded sharp cheddar cheese
1 tablespoon Worcestershire sauce
1 teaspoon garlic powder
1 teaspoon onion powder
1 teaspoon smoked paprika
½ teaspoon black pepper
1 teaspoon salt
1 tablespoon ketchup
1 teaspoon yellow mustard
Firecracker Glaze
¼ cup barbecue sauce
1 tablespoon hot sauce
1 tablespoon honey
1 teaspoon chili flakes
½ teaspoon smoked paprika
Optional Toppings
Pickles
Green onions
Extra shredded cheese
Crispy fried onions
Jalapeño slices
Preparation Time
Prep Time: 25 minutes
Cook Time: 45–55 minutes
Total Time: About 1 hour 20 minutes
Servings: 4 large onion bombs
Step 1: Prepare the Onions
Peel the onions and cut off the ends. Slice each onion in half through the equator rather than from top to bottom.
Carefully separate the layers. You’ll need the larger outer layers because these will form the shell of the onion bombs.
Set aside several onion cups of different sizes.
Step 2: Make the Cheeseburger Filling
In a large bowl combine:
Ground beef
Worcestershire sauce
Garlic powder
Onion powder
Smoked paprika
Salt
Black pepper
Ketchup
Mustard
Mix gently until everything is combined. Avoid overmixing because that can make the meat dense instead of juicy.
Fold in the shredded cheddar cheese, leaving a handful for topping later.
Step 3: Stuff the Onion Layers
Take two onion halves and place one inside the other to create a thicker shell.
Fill the center generously with the cheeseburger mixture.
Top with additional cheddar cheese.
Place another onion layer over the top to completely enclose the filling.
Repeat until all four onion bombs are assembled.
Step 4: Wrap with Bacon
Wrap two slices of bacon around each onion bomb, crossing them to secure the onion layers together.
Use toothpicks if necessary to keep the bacon in place.
The bacon not only adds incredible flavor but also helps hold the entire bomb together while cooking.
Step 5: Prepare the Firecracker Sauce
In a small bowl whisk together:
Barbecue sauce
Hot sauce
Honey
Chili flakes
Smoked paprika
This sweet and spicy glaze gives these onion bombs their signature “firecracker” kick.
Reserve half the sauce for serving later.
Step 6: Bake or Smoke
Oven Method
Preheat your oven to 375°F (190°C).
Place the onion bombs on a wire rack over a baking sheet. This allows the heat to circulate evenly and lets excess fat drip away.
Bake for 40 minutes.
Brush generously with the firecracker glaze.
Return to the oven and bake another 10–15 minutes until the bacon becomes crispy and the internal temperature reaches 160°F (71°C).
Smoker Method
Preheat your smoker to 250°F (120°C).
Smoke the onion bombs for about 90 minutes.
Brush with the glaze during the final 20 minutes.
Increase the heat to 350°F for the last 15 minutes to crisp the bacon.
The smoky flavor makes these absolutely irresistible.
Step 7: Rest Before Serving
Allow the onion bombs to rest for 10 minutes after cooking.
This gives the cheese time to settle and helps retain the juices.
Slice carefully with a sharp knife to reveal the beautiful layers of onion, bacon, beef, and melted cheddar inside.
Tips for Success
Choose Sweet Onions
Vidalia or sweet onions work best because they become tender and mildly sweet when cooked.
Use 80/20 Ground Beef
The extra fat keeps the filling juicy and flavorful.
Shred Your Own Cheese
Freshly grated cheddar melts much better than pre-packaged shredded cheese.
Don’t Skip the Resting Time
Cutting too early can cause the cheese and juices to spill out.
Secure with Toothpicks
This helps keep the bacon wrapped tightly around each bomb.
