Low‑carb lettuce‑wrap beef burgers
Juicy low‑carb beef burgers wrapped in crisp iceberg lettuce with tangy mayo, melted cheddar and gherkins — quick, keto‑friendly.
A proper low‑carb dinner that doesn’t feel like punishment. These juicy beef burgers are wrapped in crisp iceberg leaves instead of buns, trimmed down for carbs but not for flavour.
They’re quick enough for a midweek supper, easy to scale for guests and ideal if you’re following keto or just avoiding starchy bread. The simple tangy mayo and melted cheddar give that familiar burger hit without the carbs.
Ingredients
- 600 g beef mince
- 5 ml salt
- 5 ml black pepper
- 5 ml smoked paprika
- 5 ml garlic powder
- 15 ml Dijon mustard
- 120 g mayonnaise
- 15 ml lemon juice
- 8 iceberg lettuce — large outer leaves, washed and dried
- 1 small red onion
- 1 medium ripe tomato
- 100 g gherkins — sliced
- 80 g mature cheddar — sliced into 4 pieces
- 15 ml olive oil
- 1 egg — lightly beaten (binder)
Instructions
Make the burger sauce: in a small bowl whisk together the mayonnaise, Dijon mustard and lemon juice. Season with a pinch of salt and black pepper. Set to one side.
Prepare the salad and veg: separate and pat dry 8 large iceberg lettuce leaves; thinly slice the red onion and ripe tomato; slice the gherkins. Put to one side for assembly.
Make the patties: in a large bowl combine the beef mince, egg, smoked paprika, garlic powder, Dijon mustard, ¾ tsp of the salt and the black pepper. Mix gently with your hands until just combined—overworking makes tough burgers. Divide into four even portions and shape into patties slightly larger than your lettuce leaves; press a shallow dimple in the centre of each patty so they cook evenly.
Chill the patties: transfer the shaped patties to a plate, cover with cling film and chill in the fridge for 30 minutes to firm up. This helps them hold together during cooking.
Cook the burgers: heat a frying pan over medium–high heat. Add the olive oil and when it’s shimmering place the patties in the pan (do not overcrowd; cook in batches if necessary). Cook for 6 minutes on the first side, then flip and cook a further 6 minutes. During the final minute place a slice of mature cheddar on each patty and cover the pan to melt.
Rest the cooked patties on a warm plate for 5 minutes. Resting lets the juices redistribute so the burgers stay juicy when you bite in.
Assemble the lettuce‑wrap burgers: spread a generous spoonful of the mayo sauce onto a lettuce leaf, top with a rested burger, add a slice of ripe tomato, some gherkin slices and a little red onion. Spoon more sauce on top and fold the lettuce around the filling. Repeat to make 4 burgers and serve immediately.
Tips
- Pat the lettuce leaves dry on kitchen paper so the sauce doesn’t make them soggy.
- Make patties ahead and keep chilled for up to 24 hours; cook from cold for best shape retention.
- If you prefer a cheesier finish, add the cheddar in the final 30–60 seconds and cover the pan to steam‑melt.
- Use a digital probe or press test for doneness: a medium burger should feel slightly springy; aim for an internal temperature of 70°C if you prefer well done.
- Leftover cooked patties freeze well—cool completely, wrap individually and freeze for up to 3 months.

FAQ
Can I make these burgers ahead of time?
Yes — shape the patties and keep them covered in the fridge for up to 24 hours. Cook straight from chilled for best results.
Can I freeze the cooked burgers?
Yes. Cool completely, wrap each patty in cling film and freeze up to 3 months. Defrost overnight in the fridge and reheat gently in a pan or oven.
How do I know when the burgers are cooked through?
Use a probe thermometer — 70°C is well done. Alternatively press the centre: it should feel springy but not rock hard for medium–well.
Can I use a low‑carb bun instead of lettuce?
Yes — a low‑carb almond‑flour bun works, but it changes texture and some recipes require psyllium husk for structure (noticeably different).
