Tikka Masala Marinated American Butterflied Leg of Lamb

Ingredients

• 1.81 kg (4 lb)butterflied American leg of lamb
• to tastekosher salt and pepper
• 170 g (6 oz)favourite jarred tikka masala sauce
• to tastered onions, to serve
• to tastequartered tomatoes, to serve
• to tastecucumber raita, to serve
• to tastenaan bread, to serve

Instructions

1. 1

   Marinate the lamb

   Put the lamb on a large baking tray and rub the tikka masala sauce over the whole surface. Season with kosher salt and pepper, wrap in cling film and refrigerate for at least 1 hour, or overnight for best results.

2. 2

   Smoke the lamb

   Preheat the smoker to 121°C (250°F). Unwrap the lamb and leave it on the counter for at least 30 minutes to come towards room temperature. When the smoker is ready, place the lamb inside and cook for about 1 hour 30 minutes, turning it halfway through, until a thermometer inserted into the meat reads 63°C (145°F). Rest for at least 3 minutes before slicing.

3. 3

   Slice and serve

   After resting, slice the lamb and arrange it on a serving platter. Serve with grilled onions, blistered tomatoes, cucumber raita and naan bread, if you like.

4. 4

   Use the grill

   If you do not have a smoker, heat a grill to medium-high. Grill the butterflied lamb for about 10 minutes on each side, then remove it from the grill and rest for 3 minutes before slicing and serving.

5. 5

   Check guidance

   The recipe note gives a USDA recommendation of 71°C (160°F) for all other cuts, and 63°C (145°F) followed by a 3-minute rest. Use the temperature guidance appropriate to your cut and cooking preference.

What is tikka masala lamb?

This is a butterflied leg of lamb dressed with tikka masala sauce and cooked over smoke or on a grill. The recipe pairs an American barbecue method with the familiar tomato-and-spice character of a jarred Indian-style sauce.

Butterflying opens the leg into a flatter piece, helping it cook more evenly than a whole bone-in joint. The short ingredient list also makes this version straightforward to prep for a gathering.

Nutrition and macros by portion

The nutrition label shows one serving as written: 550 calories, 60g protein, 3g carbs, 32g fat.

Most of the protein and fat come from the lamb, while the tikka masala sauce contributes some carbohydrate and additional fat; naan will add more carbohydrates to the plate. Serve with generous tomatoes, onions and cucumber raita, and choose a naan portion that suits your appetite.

Choose and season the lamb

Butterflied lamb: Ask a butcher to butterfly the leg if it has not already been prepared; the flatter shape is important for the cooking times given here.

Tikka masala: A ready-made sauce gives the lamb its spice and coating in one step. Since jarred sauces vary in saltiness, season the meat with salt and pepper to taste rather than adding a fixed amount.

Give the marinade time

One hour is the minimum fridge time, while an overnight rest gives the sauce longer to flavour the surface. Keep the wrapped lamb chilled during this stage.

Before smoking, unwrap the lamb and leave it on the counter for at least 30 minutes as the smoker heats. This lets the meat lose some of its chill before cooking.

Watch the temperature

Use a meat thermometer to check the thickest part of the lamb rather than relying only on the clock. The recipe calls for about 1 hour 30 minutes at 121°C (250°F), with the lamb turned halfway through.

The method specifies 63°C (145°F) and a rest of at least 3 minutes; its note also lists a separate 71°C (160°F) recommendation for other cuts. Allow for differences in thickness and smoker performance.

Rest before slicing

Resting: Leave the lamb undisturbed for at least 3 minutes after cooking, as the method directs. This also gives you time to warm or arrange the accompaniments.

Slicing: Cut across the grain where it is visible for more tender bites. Arrange the slices on a platter so guests can serve themselves.

Make it on a grill

The alternative method uses a medium-high grill for about 10 minutes per side, followed by a 3-minute rest. Grills vary in heat, so check the lamb's internal temperature rather than treating the time as a guarantee.

The smoky method suits a longer cook, while the grill offers a simpler option when you do not have a smoker. Both finish with sliced lamb served from a platter.

Build the serving platter

The suggested sides are red onions, quartered tomatoes, cucumber raita and naan bread. The method also suggests grilling the onions and blistering the tomatoes.

Cool, creamy raita and soft naan offer a contrast to the spiced lamb. Add the accompaniments alongside the meat so everyone can make a plate to suit their appetite.

Recipe notes & tips

• Use a large tray so you can coat the lamb without spilling the sauce.
• Wrap the lamb securely before refrigerating it for the marinade.
• Start heating the smoker while the unwrapped lamb rests on the counter.
• Turn the lamb once, halfway through the smoking time.
• Check the thickest part with a thermometer before taking the lamb off the heat.
• Slice the lamb after its rest and serve it while warm.

Variations

• Add fresh herbs: Scatter chopped coriander over the sliced lamb just before serving.
• Char the onions: Grill the red onions alongside the lamb for the suggested smoky accompaniment.
• Blister the tomatoes: Cook the quartered tomatoes briefly on the grill until their edges are lightly charred.
• Serve with flatbread: Use naan to make the platter easy to share.
• Use the smoker: Choose the smoker method for a longer cook with a smoky finish.

Common mistakes to avoid

• Skipping the marinade: Give the lamb at least 1 hour in the fridge so the sauce has time to coat it.
• Cooking by time alone: Check the internal temperature because lamb thickness and equipment can vary.
• Forgetting to turn it: Flip the lamb halfway through the smoking time for more even cooking.
• Slicing immediately: Rest the cooked lamb for at least 3 minutes before cutting.
• Leaving out the thermometer: Use one to verify the temperature in the thickest part of the meat.

How to store

Refrigerate leftover lamb in a covered container within 2 hours and use within 3–4 days. Reheat gently until hot throughout, or serve the slices cold in naan; store raita separately and follow its pack or recipe guidance.
