If you’re in need of a hefty dose of protein, this stuffed onion bomb recipe will certainly do the trick! Each portion is literally packed with flavorful ground beef, encased in a juicy sweet onion shell, and then wrapped in smoky bacon for good measure. You could also cook these onion bombs on a grill, so you don’t have to be left eating a bunless cheeseburger at any future barbecues!

How to Make It

Step 1

Preheat an oven to 400 degrees. In a bowl, combine the ground beef with the shredded cheddar cheese, garlic powder, salt, pepper, italian seasoning, cayenne, and mustard powder. Set this aside.

Step 2

To prepare the onion shells, grab 3-6 large onions that are as round as possible. You will be using only the largest outer layers of each onion. Remove the tops and bottoms of all the onions, and peel away the brown skins.

Step 3

Cut each onion in half, long ways. Use your fingers to gently remove one to two layers from each onion. You should end up with 12 onion halves total, which will make 6 onion bombs. If some of the layers are still a little green, this is okay.

Step 4

Fill each onion half with ground beef. Don’t let the ground beef filling dome over, but don’t pack it in too tightly either.

Step 5

Separate your bacon slices so they are easily accessible. To assemble the onion bombs, press together two filled halves to make a whole. Wrap two pieces of bacon over the top of the onion, so they close under the entire thing. Wrap a third piece around the center. Use two skewers per onion bomb to secure everything in place.

Step 6

Place the onion bombs evenly across a metal oven rack, and place that over a sheet tray for catching any drippings (there will be a lot). Bake for 40-50 minutes, or until the center of each onion bomb has an internal temperature of 160 degrees. Serve hot!
