Ingredients

2 large sweet onions (Vidalia or Walla Walla work well)
1 pound lean ground beef
6 slices thick-cut bacon, cooked and crumbled
1 cup shredded sharp cheddar cheese
1 packet (about 1 ounce) firecracker or spicy ranch seasoning mix (or 2 tablespoons your favorite burger seasoning)
Optional: ¼ cup breadcrumbs or crushed pork rinds (for low-carb) to bind
Optional: Ranch or spicy mayo for dipping

Directions

1. Preheat and prepare. Preheat your oven to 400°F (200°C). Line a baking sheet with parchment paper or lightly grease it.

2. Prepare the onions. Peel the onions and cut them into 1-inch thick slices. Separate the slices into individual rings. You’ll need about 16 large rings (8 for the bottom, 8 for the top) to create the “bombs.”

3. Make the filling. In a large bowl, combine the ground beef, crumbled bacon, shredded cheddar cheese, and firecracker seasoning mix. Mix until well combined. If the mixture seems too loose, add breadcrumbs or crushed pork rinds to help bind it.

4. Assemble the onion bombs. Place one onion ring on the prepared baking sheet. Scoop about ¼ cup of the beef mixture into the center of the ring, pressing it down firmly and mounding it slightly. Top with another onion ring to create a “sandwich” effect. Gently press the top ring down so the filling stays inside. Repeat with the remaining rings and filling.

5. Bake. Bake for 25 to 30 minutes, until the beef is cooked through (internal temperature reaches 160°F) and the onion rings are tender and slightly caramelized.

6. Rest and serve. Let the onion bombs rest for 5 minutes before serving. This allows the filling to set and makes them easier to handle. Serve warm with ranch or spicy mayo for dipping.

Variations

Different cheese: Try pepper jack, smoked Gouda, or blue cheese.
Spicy kick: Add diced jalapeños or a dash of hot sauce to the filling.
Turkey version: Use ground turkey instead of beef.
Add veggies: Fold in finely diced bell peppers or mushrooms.
BBQ twist: Add 2 tablespoons BBQ sauce to the filling.
Low-carb: Skip the breadcrumbs and use crushed pork rinds.
Air fryer: Cook at 375°F for 15-18 minutes.

Expert Tips

Choose large onions. They make the best rings for stuffing.
Don’t overmix the filling.Overmixing can make the beef tough.
Press firmly. Make sure the filling stays inside the onion rings.
Check temperature. Ensure the beef reaches 160°F for safety.
Let them rest. Resting helps the bombs hold together.

Storage and Reheating

Storage: Store leftovers in an airtight container in the refrigerator for up to 4 days.

Reheating: Reheat in a 350°F oven for 10-12 minutes or in the air fryer at 375°F for 5-7 minutes. Avoid microwaving—it makes the onions soggy.

Freezing: Freeze cooked onion bombs for up to 3 months. Reheat from frozen in the oven.
