What Are Bacon Cheddar Onion Bombs?

These are large, savory stuffed onions. The outer layers of onion act like a shell, cradling seasoned ground beef and melted cheddar in the center. Once stuffed, each “bomb” is wrapped in bacon and secured with toothpicks or skewers. You can cook them in the oven or, for a smoky flavor, on a grill or smoker.

Ingredients

Here’s what you’ll need to make 4–6 bacon cheddar onion bombs:

• 4 large yellow or sweet onions
• 1 lb ground beef
• 1 cup shredded cheddar or cheese cubes
• ½ cup breadcrumbs
• 1 egg
• ¼ cup whole milk
• 1 tsp garlic powder
• 1 tsp onion powder
• 1 tbsp Worcestershire sauce
• Salt and pepper to taste
• 12–16 slices of bacon
• Optional: BBQ sauce or glaze

Kitchen Tools

Sharp knife, cutting board, skewers or toothpicks, mixing bowl, baking tray or grill pan, foil, meat thermometer

How to Make the Bacon Cheddar Onion Bombs

Cut the top and bottom of each onion, remove the skin, and separate the outer two layers into cups. Mix the ground beef with breadcrumbs, egg, milk, seasonings, and cheese. Form into meatballs and sandwich each one between two onion halves. Wrap tightly in 3–4 slices of bacon, securing with toothpicks.

Oven Method: Preheat to 375°F. Place bombs on a rack in a foil-lined tray. Bake 40–50 minutes until internal temp is 160°F. Broil for 2–3 minutes for crispiness.
Grill Method: Cook over indirect heat at 275°F for 1.5–2 hours. Add BBQ glaze in final 15 minutes if desired.

Flavor Variations

Try adding diced jalapeños and cream cheese to the filling for a spicy popper version. Swap in pepper jack for extra heat, or use Swiss cheese and mushrooms for a gourmet twist. You can even make it keto by using almond flour and a low-carb BBQ sauce.

Expert Tips

• Use large onions so they’re easier to stuff

• Always secure bacon with toothpicks
• Rest the bombs 5 minutes before serving to hold shape
• For extra flavor, brush with BBQ glaze before the last 10 minutes of cooking

Common FAQs

Can I bake these instead of grilling? Yes. The oven works well at 375°F for about 45 minutes. Broil at the end for crispy bacon.

What kind of cheese works best? Cheddar melts beautifully, but mozzarella, pepper jack, or even gouda will give great results too.

Can I use a different meat? Absolutely. Ground turkey or pork both work well and take on flavor nicely.

Are they keto-friendly? Yes—just skip the breadcrumbs and use low-carb BBQ sauce.

Can I prep these ahead for a party? Definitely. Assemble the day before and refrigerate.
