In a bowl, mix together the ground beef, garlic powder, onion powder, salt, and black pepper.
Form the mixture into 4 patties.
Heat the olive oil in a large skillet over medium-high heat. Add the patties to the skillet and cook for 3-4 minutes per side, or until they are cooked to your desired level of doneness.
During the last few minutes of cooking, add the mushrooms and onions to the skillet. Cook until they are tender.
If using cheese, top each patty with a slice during the last minute of cooking, so that it can melt.
To assemble the bunless burgers, place each patty on a lettuce leaf and top with tomato slices and other desired toppings. Enjoy!
Here are a few more tips and ideas for this bunless burger recipe:
If you're not a fan of mushrooms or onions, you can omit them or use any other vegetables you prefer. Some good options might include bell peppers, zucchini, or sliced avocado.
If you don't have ground beef, you can use any other ground meat you like, such as turkey, chicken, or lamb. You can also use a plant-based protein, such as crumbled tofu or tempeh.
Instead of cheddar cheese, you can use any other type of cheese you like. Some good options might include mozzarella, gouda, or blue cheese. You can also omit the cheese entirely for a dairy-free option.
You can use any type of lettuce you like for the bunless burger "buns," such as romaine, iceberg, or butter lettuce. You can also use other types of low-carb wrap or bun, such as a coconut flour tortilla or a portobello mushroom cap.
To add some extra flavor to the burgers, you can mix in some diced jalapeno peppers, diced sun-dried tomatoes, or a spoonful of your favorite burger seasoning blend.
If you're not a fan of lettuce, you can serve the burgers on top of a bed of mixed greens or a spinach salad, or you can use them to make lettuce wraps with other vegetables, such as sliced bell peppers or carrot sticks.
You can serve the bunless burgers with a side of low-carb vegetables, such as roasted broccoli or grilled asparagus, or with a salad. They also go well with a variety of low-carb dips, such as guacamole or ranch dressing.
