Ingredients Needed
For the Fajitas
- 12 corn or wheat tortillas
- 4 lamb leg steaks (roughly 100g/3.5oz each)
- 3 peppers, sliced finely
- 2 large onions, sliced finely
- Salsa, guacamole, sour cream (plus any other toppings you love)
- Fresh coriander / cilantro (optional)
For the Fajita Seasoning
- 3 teaspoons ground cumin
- 2 teaspoons cayenne pepper
- 3 teaspoons dried oregano
- 3 cloves garlic, grated or crushed
- 3 teaspoons smoked paprika
- Pinch of salt
- Juice of 2 limes
- 2 tablespoons olive oil
How To Make Jamie Oliver Lamb Fajitas
Prep the Oven and Tortillas:
Start by preheating your oven to 180°C (160°C fan) / gas mark 4 / 350°F. Wrap the tortillas in foil and pop them into the oven once it’s hot. Let them warm through for 10 minutes, then take them out and set aside.
Make the Seasoning:
In a small bowl, combine the cumin, cayenne pepper, oregano, garlic, smoked paprika, salt, lime juice, and olive oil. This mix smells incredible already!
Marinate the Lamb:
Coat the lamb leg steaks thoroughly with your seasoning mix. If time allows, let them marinate for up to 2 hours to soak up all that goodness.
Sear the Lamb:
Heat a griddle or frying pan over high heat. Once hot, cook each lamb steak for 1 minute per side to get a good sear, then continue for another 2 minutes per side—about 6 minutes total. Rest the lamb on a plate.
Sauté the Veggies:
In another pan, heat a splash of oil over high heat. Toss in the sliced peppers and onions and stir-fry for about 3–4 minutes until they’re browned but still a bit crisp. Lower the heat and mix in any remaining fajita seasoning. Cook for 2 more minutes.
Bring it Together:
Slice the rested lamb into strips and return it to the pan with the veggies. Give everything a gentle mix. Sprinkle with fresh coriander if using, then bring it all to the table with those warm tortillas and your favourite toppings.

Why I Love This Recipe
I made this on a whim midweek and it completely elevated my dinner game. The lamb was juicy and deeply spiced, while the veg added that perfect crunch. My partner raved about it, and we ended up building our own fajitas right at the table—fun and delicious.
Recipe Tips
- Slice the lamb against the grain for maximum tenderness.
- Don’t overcrowd your pan when searing—the lamb needs room to caramelise.
- Control the heat: Adjust cayenne to taste or add sliced fresh chilli for extra fire.
- Marinate for flavour: Even 30 minutes makes a noticeable difference.
- Swap tortillas for pita, lettuce wraps, or even naan for fun variations.
