Low Carb 3-Ingredient Bacon Onion Bakes
Servings: 6
Ingredients
2 large sweet onions, sliced into thick rounds
12 slices bacon
1/2 teaspoon black pepper
Directions
1. Preheat the oven to 400 degrees Fahrenheit and line a baking sheet or shallow baking pan with foil for easier cleanup.
2. Separate the onion slices into thick rings or keep smaller rounds intact, then wrap each piece snugly with one slice of bacon and place seam-side down on the prepared pan. Sprinkle the tops lightly with black pepper.
3. Bake for 25 to 35 minutes, turning once if needed, until the bacon is browned and crisp and the onions are soft and tender in the center.
4. Let them rest for 5 minutes, then transfer to a plate and serve warm.
Variations & Tips
Add a little heat: If your family likes a spicy bite, sprinkle the wrapped onions with a pinch of cayenne or smoked paprika before baking. It keeps the ingredient list simple but gives the bacon a deeper flavor.
For picky eaters: Use sweet onions rather than sharp yellow onions, since they mellow beautifully in the oven and turn softer and sweeter. That little change makes these much more kid-friendly for folks who usually say they do not like onions.
Keep the bacon in place: If your bacon slices are short or thick, secure the ends with toothpicks before baking. This helps everything stay neatly wrapped until the bacon tightens up and crisps.
Make them crispier: Set the baked onion bakes on a wire rack over the pan so the hot air can move around them more evenly. You can also broil them for 1 to 2 minutes at the end, watching closely so the bacon does not burn.
Choose the right size: Cut the onions thick enough that they stay sturdy during baking, about 3/4 inch is a good target. If the slices are too thin, the onions soften too quickly before the bacon has time to crisp.
