Who needs a bun? Try this delicious bunless burger instead. Simply sandwich your fillings between two beef patties! You can add mustard, mayo, cheese, and veggies, or just a slice of cheese for the simplest version.

I used to love bread, but now I consider it an unnecessary filler (though I still have several good recipes for keto bread). I'd much rather have an extra beef patty! This bunless burger is the perfect solution for those on a low-carb diet. Just like this cheeseburger casserole, it focuses on beef, cheese, and vegetables while foregoing the bread.
Ingredients
See the recipe card for exact measurements. Here are my comments on some of the ingredients.
- Ground beef patties: I typically use an 85/15 mixture.
- Mustard: I prefer Dijon mustard. You can also use mayo or sriracha mayo.
- Red onion: If you dislike the sharpness of raw onion, you can simply omit it. You can also use sauteed onions or caramelized onions if you happen to have some (or if you have the patience to make them!)
- Cheese: I usually use sharp cheddar. Swiss cheese and smoked Gouda are also good.
Instructions
The detailed instructions and step-by-step photos are included in the recipe card. Here's a quick overview.
Season the beef patties with salt and pepper. Cook them to your desired doneness. I cook them to medium, about 3 minutes per side. Transfer the patties to a plate and allow them to rest, loosely covered in foil, for 5 minutes. While the meat is resting, gather the remaining ingredients.
To assemble the "sandwiches," grab two plates. Place a cooked patty on each plate and spread it with mustard. On top of the mustard, layer the lettuce, onion, tomato, and cheese, and then top with another cooked patty. Serve immediately.
Recipe Tips
- I prefer to use pre-formed beef patties because they are more uniform and keep their shape better when cooked than the ones I shape by hand.
- It's important to let the burgers rest for 5 minutes before serving them. This rest period will allow the juices to redistribute and settle, ensuring juicy burgers.
- This bunless burger is quite messy and will require extra napkins. But it's admittedly more fun than using a knife and a fork, and it is always a hit with kids, who find the "meat bun" funny - and fun. The kids enjoy not just eating these burgers but also assembling them. But for a more dainty experience, use iceberg lettuce or cloud bread as your burger bun.
- Make-ahead: You can pre-cook the patties and keep them in an airtight container in the fridge for up to 4 days. Reheat them in the microwave before assembling the "sandwich." You can also freeze the patties for up to three months. Thaw them overnight in the fridge before reheating them.
Serving Suggestions
- Vegetables: I usually serve this burger with vegetables, such as steamed broccoli or green beans.
- Pickles: It's also good with quick pickles or pickled red onions.
- Fries: Try it with a side of jicama fries or zucchini fries.
- Salad: An easy side dish is a salad like arugula salad, homemade coleslaw, or tomato salad.
- Toppings: Top your burger with toppings such as sliced avocado, a fried egg, and/or oven bacon, and eat it with a knife and a fork.
