Bacon Cheddar Onion Bombs

Our family discovered onion bombs during a weeknight dinner rut craving something cozy and old-school but with a certain wow factor. Tender beef stuffed with melty cheddar, hugged in sweet onion and crispy bacon, always disappears fast—especially when brushed with tangy barbecue sauce and baked to smoky perfection.

My kids declared these better than meatloaf or burgers the first time I made them so now they ask for onion bombs for every casual get-together.

Ingredients

• Yellow onions: form the savory shell for the beef and cheese filling choose onions that feel heavy and firm for their size so the layers hold up during stuffing
• Lean ground beef: keeps the filling juicy but not greasy look for eighty five to ninety three percent lean for best results and no excess fat pooling
• Bread crumbs: help bind the beef mixture and make it tender choose plain or seasoned store-bought crumbs
• Large egg: aids in binding the beef while adding richness use a fresh egg with a bright yolk for optimal moisture
• Whole milk: softens the bread crumbs slightly for a moist texture whole milk brings best flavor
• Barbecue sauce: provides tang and caramelization during baking Sweet Baby Ray’s works deliciously but any thick and sweet BBQ sauce will work
• Garlic powder and onion powder: add big flavor to every bite go for fresh spices so flavors shine
• Salt and black pepper: season the meat evenly use kosher salt for balanced seasoning and fresh cracked pepper if available
• Cheddar cheese cubes: give that classic gooey center use firm sharp cheddar cut into even squares for best melting
• Center-cut smoked bacon: wraps the whole bomb in smoky goodness pick bacon with a good meat to fat ratio so it gets crisp without being chewy

Step-by-Step Instructions

Prepare Onions:

Trim the top and bottom off each onion and peel the outer skin. Slice each onion in half from top to bottom. Remove the two outermost thickest layers from each half, keeping these intact as you will use them to form the onion bombs. You should have eight sets of two sturdy onion halves.

Mix the Meat Filling:

In a large mixing bowl, combine the ground beef, bread crumbs, egg, milk, three tablespoons of barbecue sauce, garlic powder, onion powder, salt, and black pepper. Use clean hands or a sturdy spoon to thoroughly mix until all ingredients are evenly distributed and the mixture feels slightly sticky but holds together.

Divide and Shape:

Portion the meat mixture into eight equal balls. Flatten each ball into a round disc about three to four inches across in your palm.

Add Cheese:

Place a cheddar cheese cube in the center of each beef disc. Mold the beef gently but tightly around the cheese, sealing it in to create a stuffed meatball.

Assemble Onion Shells:

Place the prepared meatball between two matching onion halves so that the onion surrounds as much of the meatball as possible. If your pieces don’t fit perfectly, arrange as needed so the meatball is fully encased.

Wrap with Bacon:

Lay two slices of bacon in an X shape on your work surface. Set an onion-wrapped meatball in the center then tuck the bacon ends up and around to totally enclose the whole bomb. Use a toothpick if a piece tries to unravel but often the bacon holds tight on its own.

Bake:

Arrange all assembled bombs seam-side down on a foil-lined baking sheet. Bake at four hundred twenty five degrees for thirty minutes until the bacon is beginning to crisp and the onions soften.

Brush with Sauce and Finish Baking:

Remove the baking sheet and brush the tops and sides of each onion bomb with the remaining barbecue sauce. Return to oven and bake for ten to fifteen minutes more until the sauce is bubbly and caramelized and a meat thermometer reads one hundred sixty to one hundred sixty five degrees inside the beef.

Rest and Serve:

Let the onion bombs sit for at least five minutes so the cheese sets slightly before you serve. Enjoy these gooey savory treats while hot.

Save

My favorite part is cracking into that smoky onion shell then seeing the gooey cheddar ooze out with every cut. The first time I made these for game night everyone grabbed seconds and begged for the recipe—now they are a regular fixture at our table.

Storage Tips

Onion bombs keep covered in the refrigerator for up to three days. To reheat, place them uncovered on a baking sheet in a three hundred fifty degree oven so the bacon crisps back up. You can assemble the bombs the day before and bake fresh when needed or freeze them raw then add five to ten minutes to bake from frozen.

Ingredient Substitutions

Ground chicken or turkey makes a lighter but equally moist filling just make sure it is not too lean or the mixture will dry out. Monterey Jack or pepper jack cheese is a fun swap for cheddar if you want a melty center with extra flavor. If you are out of barbecue sauce use ketchup mixed with a dash of brown sugar and a splash of vinegar as your glaze.

Serving Suggestions

Serve onion bombs over fluffy mashed potatoes rice or alongside a crunchy green salad to keep the meal balanced. For parties cut them into halves or quarters and set them out with toothpicks for easy grazing. These also make a hearty sandwich filling if tucked into buns with more barbecue sauce and pickles.

Recipe FAQs

→ How do I keep onion bombs from falling apart during baking?

Wrap each bomb tightly with bacon and use thick, evenly sized onion layers. Gently press the beef mixture together before assembling. Securing with toothpicks can add extra hold.

→ Can I use different cheese for the stuffing?

Yes, swap cheddar for mozzarella, pepper jack, or gouda for varied flavor and melt. Cut cheese into similar-sized cubes for even results.

→ Is a meat thermometer necessary?

Using a thermometer ensures the beef is fully cooked (internal temperature 160-165°F). If unavailable, check that the bacon is crisp and onions are fork-tender.

→ Why wait to brush barbecue sauce until near the end?

Applying sauce late prevents burning and allows the surface to caramelize without drying out or overcooking the bacon and onions.

→ Can these be prepared ahead of time?

You can assemble bombs up to a day ahead and refrigerate. Bake just before serving for best taste and texture.

→ How do I make the onions easier to separate?

Soak sliced onion halves in hot water for a few minutes before peeling the outer layers to prevent breaking.
