Ingredients

4 large yellow onions
1 ½ pounds ground beef (80/20 preferred)
1 cup sharp cheddar cheese, shredded
½ cup breadcrumbs
1 large egg
2 tablespoons barbecue sauce
1 tablespoon hot sauce (preferably sriracha or similar)
½ teaspoon smoked paprika
½ teaspoon garlic powder
½ teaspoon onion powder
1 teaspoon salt
½ teaspoon black pepper
16 slices thick-cut bacon
Extra barbecue sauce for glazing
Fresh chopped parsley or green onions (optional, for garnish)

Directions

Prep the Onions

Preheat oven to 400°F (200°C), or preheat grill to medium heat (around 400°F).
Peel onions and slice off both ends. Carefully remove the outer 2–3 layers to create large, hollow onion shells. Set aside. Reserve inner onion pieces for another use.

Make the Burger Filling

In a bowl, combine ground beef, cheddar cheese, breadcrumbs, egg, barbecue sauce, hot sauce, smoked paprika, garlic powder, onion powder, salt, and black pepper. Mix gently until just combined—don’t overwork the meat.

Assemble the Onion Bombs

Divide the beef mixture into 4–6 equal portions, depending on onion size. Shape each portion into a ball and gently stuff each meatball into an onion shell, pressing to fill completely.
Wrap each stuffed onion completely with 2–3 slices of bacon, securing with toothpicks if needed to keep the bacon in place.

Cook the Onion Bombs

Place the bacon-wrapped bombs onto a parchment-lined baking sheet or a grill-safe pan. Brush with a little extra barbecue sauce.
Bake or grill for 40–45 minutes, brushing again with barbecue sauce during the last 10 minutes, until bacon is crisp and beef is fully cooked (internal temp should reach 160°F/71°C).

Rest & Serve

Let the bombs rest 5 minutes before serving. Garnish with parsley or green onions if desired. Slice in half for that delicious cheesy middle!

Notes

Use thick-cut bacon for best results, as thinner bacon may overcook before the beef is done.
Don’t over-pack the meat mixture or your bombs may be tough. Gentle hands make juicier burgers!
If you love extra heat, add a pinch of crushed red pepper to the burger mix.

Variations

Jalapeño Popper: Add diced jalapeños and a tablespoon of cream cheese to the filling for a spicy, creamy twist.
BBQ Ranch: Swap the hot sauce for ranch seasoning and use Monterey Jack cheese.
Mushroom Swiss: Substitute Swiss cheese and fold in sautéed mushrooms for a classic burger vibe.

Required Equipment

Baking sheet (for oven) or grill-safe pan (for grill)
Parchment paper or foil
Sharp knife
Mixing bowl
Toothpicks
Basting brush
Meat thermometer

Storage Instructions

Store leftovers in an airtight container in the refrigerator for up to 3 days.
Reheat in a 350°F oven for about 10 minutes until heated through—the bacon will crisp back up!
Not recommended for freezing, as onions become mushy when thawed.

Serving Recommendations

Try pairing with grilled corn on the cob, loaded potato salad, or crispy fries for a full backyard feast.
Serve with pickles, extra BBQ sauce, or a cool ranch dip on the side.
A crisp, cold lager or lemonade makes a fantastic drink pairing!

Pro Tips

Use kitchen gloves when handling raw onions and spicy sauce to avoid skin irritation.
Let the onion bombs rest after cooking so juices redistribute for even more flavor.
If using the grill, set up indirect heat to prevent bacon flare-ups and burning.
