Recipe Overview:

🛒 Main ingredients: Ground beef, yellow onions, cheddar cheese, bacon, barbecue sauce

🔪 Quick steps: Shape cheese-filled meatballs, wrap with onion halves and bacon, bake, coat with barbecue sauce, then bake again

⏲️ Total time & yield: 1 hour 5 minutes; makes 8 onion bombs

WHAT YOU'LL NEED FOR ONION BOMBS:

• 4 medium-sized yellow onions
• 2 pounds lean ground beef (93%-7% blend)
• ½ cup bread crumbs
• 1 large egg
• ¼ cup whole milk
• ⅓ cup + 3 tablespoons barbecue sauce
• 1 teaspoon garlic powder
• 1 teaspoon onion powder
• 1 teaspoon salt
• ¼ teaspoon black pepper
• 8 (1-inch sized) cheddar cheese cubes
• 16 pieces center-cut smoked bacon

🧀 Cheese: Try mozzarella, pepper jack, or gouda cubes instead.

🥩 Meat: Swap beef for ground pork, turkey, or chicken. We especially love pork bombs, made from a 50/50 blend of ground pork and beef.

🌶 Spice it up: Add jalapeños or red pepper flakes to the ground beef mixture.

🥓 Bacon alternatives: We haven't tried it, but you could experiment with prosciutto, pancetta, or turkey bacon.

🌿 Herbs: Add fresh parsley, chives, or cilantro to the beef mixture for brightness.

🍯 Sauce swap: We love smoky BBQ sauce, like Sweet Baby Ray's Original, but you can try honey mustard, teriyaki, or spicy chili glaze for different flavors.

LOVE ONIONS?
You’ll have extra onions since you only need the outer shells. Use the rest to make Oklahoma fried onion burgers, fried potatoes with onions, or crispy homemade onion rings.

Follow these pictures, instructions, and tips to make perfect onion balls. You’ll see exactly how to wrap, bake, and glaze each one for the best results. Let’s get started!

First preheat your oven and line a rimmed baking sheet with aluminum foil. Set the baking pan aside for now.

FIRST STEP: Slice the top and bottom off of each onion, and peel off the outer skin layer. Slice the onions in half (top to bottom) and remove the two outer layers of the onion.

The large pieces of onions will wrap around your meatballs like an onion seal, holding them together. You should end up with eight sets of onion halves. Set them aside for now.

SECOND STEP: Add the ground beef, bread crumbs, egg, milk, garlic powder, onion powder, salt, black pepper, and 3 tablespoons of the barbecue sauce to a large bowl.

Mix the ingredients together until they are combined and all the ingredients are evenly incorporated.

THIRD STEP: Divide the mixture into eight equal portions.

FOURTH STEP: STEP #4 Pick up one portion of the ground beef mixture and flatten it in the palm of your hand so it’s roughly a three to four inch sized disc.

FIFTH STEP: Add one cube of cheddar cheese to the center of the ground beef disc, then wrap the sides up around the cheese cube to form a large, cheese stuffed onion bomb.

SIXTH STEP: Choose two equal-sized onion halves to place on either side of your meatball. Most of the surface of the meatball should be covered by the pieces of onion. Choose the size of the onions based on the size of your meatball.

SEVENTH STEP: Lay two strips of bacon in an X-pattern and set the stuffed onion bomb in the center. Pull each slice of bacon up and around the onion bomb. 

EIGHTH STEP: Place the bacon wrapped stuffed onion onto the baking sheet. Repeat the process until all the onion bombs have been assembled. 

NINTH STEP: Bake for 30 minutes. Remove the onion-wrapped meatballs from the oven and brush the top and sides of each one with the remaining third cup of barbecue sauce.

Place the baking sheet back in the oven and continue to cook them for another 10-15 minutes. When the barbecue sauce has caramelized and the internal temperature of the onion bombs reaches 160-165°F, they’re done cooking.

TENTH STEP: Remove the onion bombs from the oven and allow them to rest for five minutes. Serve hot.

This bacon wrapped onions and meatballs recipe makes a crowd-pleasing choice for a celebration dinner or a cozy Saturday family night.

Here are a few tasty ways to serve them:

🥇 Classic BBQ Feast: Pair these juicy onion BBQ bombs with corn on the cob, baked beans, and coleslaw. The smoky barbecue sauce pairs perfectly with the crispy bacon and tender beef.

🥈 Comfort Food Dinner: Serve these cheesy stuffed meatballs with Caesar salad, mashed potatoes, and creamed corn. This combination creates a warm and satisfying meal.

🥉 Beverage Pairing: For a refreshing drink, enjoy them with homemade strawberry lemonade or a strawberry lemonade cocktail for the adults.

• Bold Flavor – Juicy beef, smoky bacon, and melty cheddar in every bite. Yum!
• Fun & Unique – Wrapped onions turn into a crispy, caramelized shell.
• Perfect for Sharing – Meat bombs are a hit at game day, barbecues, or family dinners.
• Easy Comfort Food – Simple ingredients, big payoff, no fuss. Onion bombs are surprisingly easy to make!

• If separating onion layers is tricky, soak the peeled onion halves in hot water for three to four minutes to soften them.
• Use thick, evenly sized onion layers for each bomb so they cook evenly without leaving some of your bombs too firm or too soft.
• For extra smoky flavor without a smoker, add a small pinch of smoked paprika to the meat mixture before shaping.
• Pack the cheddar cheese cube tightly inside the meat to keep it from melting out before the meat finishes cooking. Make sure there aren't any holes or gaps.
• Wrap the bacon snugly around each onion bomb and use your hands to firmly press the meat mixture together so it holds its shape.
• Check doneness with a meat thermometer for accuracy. Look for an internal temperature of 160°F for ground beef. If you don’t have a thermometer, make sure the bacon is golden, onions are tender, and meat is fully cooked before serving. (You might have to make a small slice in one to check the ground beef for doneness.)
• Wait until the onion bombs are nearly done before adding barbecue sauce to avoid burning or over-caramelizing it.
• Let the onion bombs rest for a few minutes after baking so the juices redistribute and the cheese sets slightly before serving.

What’s the best way to serve onion bombs for a crowd?
Slice each onion bomb in half or quarters for easy sharing. Arrange them on a large platter for a fun presentation.

Serve them hot so the cheese stays melted and the bacon stays crispy. They’re best straight from the oven.

Can onion bombs work for holiday dinners?
Absolutely! While not traditional holiday food, their rich flavor and festive look make them a fun addition to any dinner table. They're an especially delicious addition to your summer holiday grill-outs, or birthday celebrations.

Do onion bombs work well for outdoor gatherings?
Yes, they’re perfect on the grill, and go really well with potato salads and other BBQ sides.

You can prep these ahead and store them, so they're easy to make on a busy night or if you're having company!

MAKE-AHEAD - Here’s how to make ahead and store them to keep them fresh:

1. Assemble them completely and cover the baking sheet tightly with plastic wrap to prevent any air exposure. Store in the fridge for up to a day before baking.

Leftovers:

❄️ Refrigerate 3–4 days in an airtight container

How To Freeze: Freeze your onion bombs after they are cooked and thoroughly cooled. Place them in a single layer on a baking sheet and pop them in the freezer.

Once frozen, transfer them to a freezer-safe bag or container. Store them for up to three months. Thaw them overnight in the refrigerator before reheating.

To reheat: Reheat in the oven at 350 degrees until warmed through for the best texture. This keeps the bacon crisp and the cheese melted.

Ingredients

  

1x2x3x

• 4 medium-sized yellow onions (you will use the outer 2 layers of each onion)
• 2 pounds lean ground beef (93%-7% blend)
• ½ cup bread crumbs
• 1 large egg
• ¼ cup whole milk
• ⅓ cup bottled barbecue sauce (to brush onto the onion bombs when baked (We used Sweet Baby Ray’s original))
• 3 tablespoons bottled barbecue sauce (for the meat mixture (We used Sweet Baby Ray’s original))
• 1 teaspoon garlic powder
• 1 teaspoon onion powder
• 1 teaspoon salt
• ¼ teaspoon black pepper
• 8 cheddar cheese cubes (1-inch sized)
• 16 pieces center-cut smoked bacon

DIRECTIONS

 

• Preheat oven to 425°F. Line a large-rimmed baking sheet with aluminum foil. Set aside.
• Prepare the onions by slicing the top and bottom off of each onion. Peel off the outer skin layer. Slice the onions in half (top to bottom) and remove the two outer layers of onion. These will be your two largest pieces from each onion, giving you a total of 8 sets of onion halves. Set aside.
• Add the lean ground beef, bread crumbs, egg, milk, 3 tablespoons bottled barbecue sauce, garlic powder, onion powder, salt, and black pepper to a large mixing bowl. Using a wooden spoon or your hands, mix the ingredients together until they are combined and all the ingredients are evenly incorporated.
• Divide the mixture into 8 equal portions.
• Flatten one of the portions of meat in the palm of your hand to a roughly 3-4 inch-sized disc.
• Add one cheddar cheese cube to the center of the ground beef disc, then wrap the sides up around the cheese cube to form a large cheese-filled meatball.
• Place two equal-sized onion halves on either side of the meatball. You should be covering most of the surface of the meatball. If the meatball is too large or too small, choose onion halves that fit the meatball the best.
• Lay out two pieces of bacon in an x-pattern, set the onion bomb in the center, then pull the bacon up and wrap the onion bomb with the bacon. You can secure the bacon with a toothpick if needed.
• Place the bacon-wrapped Onion Bomb onto the prepared baking sheet and repeat steps 5-8 until all the onion bombs have been assembled and placed onto the baking sheet.
• Bake for 30 minutes. Remove the onion bombs from the oven, and brush the top and sides of each onion bomb with the remaining ⅓ cup of bottled barbecue sauce. Return the onion bombs to the oven and continue baking for an additional 10-15 minutes or until the barbecue sauce has caramelized and the internal temperature of the onion bombs reaches 160-165°F.
• Allow the onion bombs to cool for 5 minutes before serving. Enjoy!

Notes

• The onion bombs won’t stay together well without bacon, or if the meat mixture is too loose. Make sure to wrap the bacon tightly around each onion bomb and gently press the meat mixture together to help keep the meatball together.
• One way to make sure your onion bombs cook evenly is to use fairly thick, evenly sized-pieces of onion for each bomb. That way, you avoid having some onion pieces undercooked and some overcooked.
• If it’s difficult to separate the onions without breaking them, you can soak them in hot water for three to four minutes. This will soften the onions and make it much easier to separate them.
• Using a meat thermometer is the most accurate way to determine the doneness of the meatball. If you don’t have one, your onion bombs should be done when the bacon is golden and crispy, and the onions can be easily pierced with a fork. You may have to cut open one of your onion bombs to make sure your ground meat is cooked through.
• You want to create a tight seal around your cheddar cheese cube. The cheese will melt before the meat is done cooking, and it might leak out if it isn’t fully encased in the meatball.
• If you like lots of BBQ sauce, you can brush extra onto the meatballs at the 30-minute mark and serve with sauce on the side.
• The barbecue sauce may burn or become too caramelized if it’s applied too early in the baking process. To prevent this, make sure to wait until the onion bombs are almost fully cooked before brushing them with barbecue sauce.
