🥑 Keto Burger
✅ Naturally: 🥑 Keto 🌾 Gluten-Free
Adaptable for: 🥛 Dairy-Free 🍃 Paleo
Drop the bun, keep everything that actually makes a burger taste like a burger. Beef, bacon, and cheese are exactly what keto is built for.
Keto is one of the easiest diets to build a burger around, because the parts keto wants — fat and protein — are the parts of a burger that were never the problem. The carbs were always hiding in the bun and in sugar-sweetened sauces like ketchup and BBQ sauce. Pull those two things out, wrap everything in crisp lettuce instead, and you have a burger that is not a compromise — it is just a really good burger that happens to fit the diet.

Ingredients
- 1.5 lb (680g) ground beef, 80/20 chuck
- 8 slices bacon
- 4 slices sharp cheddar
- 8 large iceberg or butter lettuce leaves (for wrapping)
- Keto burger sauce: 1/2 cup mayo + 1 tbsp yellow mustard + 1 tsp vinegar + pinch of salt (no ketchup)
- 1 avocado, sliced (optional, extra richness)
- Sliced tomato, red onion, dill pickles
- Kosher salt and black pepper
Instructions
- Cook the bacon in a skillet until crisp. Set aside on paper towels and keep a little of the fat in the pan.
- Form the beef into 4 dimpled patties. Season both sides with salt and pepper just before cooking.
- Sear the patties in the bacon fat over high heat, undisturbed, 3 minutes.
- Flip, top with cheddar, and cook 2–3 minutes more to 160°F (71°C) internal, covering briefly to melt the cheese.
- Whisk together the mayo, mustard, vinegar and a pinch of salt for the keto sauce.
- Lay out 2 lettuce leaves per burger, overlapping like a bun.
- Build: sauce, patty with cheddar, bacon, tomato, onion, pickles, and avocado if using.
- Fold the lettuce around the burger like a wrap, or eat it open-faced with a fork.
👨🍳 Tips for the best Keto Burger
- Sugar sneaks into cured bacon and into ketchup/BBQ sauce — check labels or use the mustard-based keto sauce above instead.
- Use full-fat mayo and cheese. Keto wants the fat; low-fat versions work against you here.
- Large butter lettuce or iceberg leaves hold up best for wrapping without tearing.
- Avocado adds extra creamy fat and helps it eat like a "real" burger instead of a diet substitute.
🥗 Make it fit your diet
Already Keto / Low-Carb + Gluten-Free-friendly — here's how to take it further:
🥛 Dairy-Free
Skip the cheese or use a dairy-free alternative, cook in oil instead of butter, and stick to dairy-free sauces (most mayo, ketchup, and mustard are fine).
🍃 Paleo / Whole30
Wrap it in lettuce (no bun), skip the cheese, and use compliant sauces with no added sugar, soy, or dairy. For Whole30, make sure any bacon is sugar-free.

Frequently asked questions
Is a burger keto without the bun?
Yes — the beef, bacon, and cheese are all naturally keto. The bun and sugary sauces are the only parts that aren't, so removing them is all it takes.
What can I use instead of a bun for a keto burger?
A lettuce wrap (sometimes called "protein style") is the easiest option. Portobello mushroom caps or a low-carb cloud-bread bun also work well.
How many carbs are in this keto burger?
Very few — mostly from the onion, tomato, and pickles, typically only a few grams net carbs per burger depending on portions.
