Sticky & Spicy Slow Cooked Irish Lamb

This Sticky & Spicy Slow Cooked Irish Lamb is packed with bold flavours from warming spices, garlic, and pesto, then cooked low and slow until perfectly tender. Made with simple, quality ingredients, it’s an easy yet impressive dish that’s perfect for Easter, Sunday roasts, or any special gathering.

I made this Sticky & Spicy Slow Cooked Irish Lamb recipe on Ireland AM earlier in the month, my first time o live TV!

There’s something about cooking live on TV that’s both exciting and nerve-wracking. I went all in with flavour, using lamb, pesto, and spices, slow cooking it until it’s falling off the bone.

The lamb is packed with cumin, oregano, paprika, garlic, sea salt, and red pesto or harissa for deep flavour. It’s cooked slowly with onion, rosemary, beef stock, water, and a drizzle of honey. It becomes rich, sticky, and slightly spicy as it cooks. The smell alone is absolutely incredible in the kitchen.

Serve it with buttery mash, roast cherry tomatoes, asparagus, or roast carrots and parsnips. It’s proper comforting, feel-good food.

It was a little nerve-wracking appearing on live TV. But I promised myself this year I would take on new challenges. I’m so glad I did. It was such an incredible experience. Thank you so much for all your support, and to Ireland AM for having me on.
