Ingredients
- 1 pound ground beef (preferably 80/20 blend)
- 4 large onions, sliced into thick rings (about 1 inch thick)
- Salt and pepper, to taste
- 4 slices of cheddar cheese
- 2 tablespoons butter or olive oil for frying
- Optional toppings: lettuce, tomato, pickles, or your favorite sauce
Step-by-Step Directions
- Prepare the Onion “Buns”:
- Slice the onions into thick rings, about 1 inch thick. You’ll need 8 large onion rings for 4 burgers.
- Use two large outer rings per burger to serve as the “bun.”
- Caramelize the Remaining Onions:
- If you have extra onion slices, you can caramelize them for added topping.
- Heat butter or olive oil in a skillet over medium heat.
- Add the extra onions and cook, stirring occasionally, until they become soft and golden brown, about 15-20 minutes. Season with a pinch of salt and pepper.
- Form and Cook the Patties:
- Divide the ground beef into 4 equal portions and form into patties. Season both sides with salt and pepper.
- In the same skillet, cook the patties over medium-high heat for about 4 minutes on each side, or until they reach your desired doneness.
- During the last minute of cooking, add a slice of cheese to each patty to melt.
- Assemble the Burgers:
- Place a cooked patty between two onion rings to create the burger “sandwich.”
- Add any additional toppings like lettuce, tomato, or pickles if desired.
- Serve:
- Serve the onion burgers hot, with a side of fries, salad, or your favorite low-carb side.
Variations
- Spicy Onion Burger: Add jalapeños or a spicy sauce for a kick.
Serving Suggestions
- Serve with a low-carb side like roasted vegetables, zucchini fries, or a fresh salad.
- Pair with a dipping sauce like garlic aioli or spicy mayo for added flavor.
Storage
- Leftovers: Store any leftover patties and onion “buns” separately in airtight containers in the refrigerator for up to 3 days.
- Reheating: Reheat the patties in a skillet over medium heat until warmed through. The onion buns can be reheated in a skillet or microwave.
