Freezer Food Challenge: Slow Cooked Lamb Leg with Garlic, Rosemary & Lemon

There are roasts… and then there is lamb — my absolute favourite roast meat. And for this latest instalment of our Freezer Food Challenge on Eat Clean, Health and Dream, I knew exactly what I wanted to cook.

A beautiful leg of lamb, slow cooked in the crock pot with garlic, rosemary and a generous squeeze of lemon. Simple. Wholesome. Packed with flavour. And best of all? It quietly cooked to perfection while Craig and I spent the afternoon dreaming big — exploring kitchen colours, layouts and design ideas for our new house in Exeter.

Because that’s what this series is all about: using what we already have, cooking real food from the freezer and fridge, and still eating like royalty.

The Star of the Show: Slow Cooked Lamb Leg

There is something incredibly comforting about lamb cooked low and slow. The garlic softens into sweetness, the rosemary infuses every bite, and the lemon lifts the richness just enough to keep it fresh and vibrant.

Ingredients

• 1 whole lamb leg

• 4–6 garlic cloves, sliced

• 2–3 sprigs fresh rosemary

• Juice of 1 lemon

• Salt & black pepper

• Optional: splash of stock or water

  
  

Method

1. Prepare the lamb – Make small incisions across the lamb and tuck slices of garlic and sprigs of rosemary inside.

2. Season generously with salt and black pepper.

3. Add lemon juice over the top for that bright, fresh finish.

4. Place into the crock pot. Add a small splash of stock or water if needed.

5. Cook on low for 7–8 hours (or high for 4–5 hours) until beautifully tender and falling apart.

The result? Melt-in-the-mouth lamb that slices like butter.

From the Freezer: Roasted Garlic & Lemon Potatoes

No roast lamb is complete without golden, crispy potatoes.

From our supplies, I used:

• White potatoes

• Sweet potatoes

• Whole garlic cloves

• Lemon zest & juice

• Olive oil

• Salt & rosemary

  
  

Roasted together until crispy on the outside and fluffy inside, with caramelised edges and that subtle citrusy kick. The sweet potatoes add natural sweetness and colour — and they’re perfect for using up freezer or pantry extras.

Fridge & Freezer Veggie Medley

This challenge is about creativity — not perfection.

From the fridge and freezer we gathered:

• Carrots

• Broccoli

• Cauliflower

• Frozen peas

• Frozen sweetcorn

  
  

Lightly steamed and seasoned, they brought freshness, colour and balance to the richness of the lamb.

Nothing fancy. Just real, nourishing food.

Cooking While Dreaming

While the crock pot worked its magic, Craig and I were off gathering inspiration for our new Exeter kitchen — colours, cabinet styles, layout ideas… dreaming of future family meals cooked in a brand-new space.

There’s something beautiful about slow cooking on days like that. You come home to a house filled with warmth and the unmistakable aroma of rosemary and garlic. It feels grounding. Comforting. Exciting — just like starting a new chapter.

The Best Part: Planned Leftovers

Once sliced, the lamb was just as good (if not better) the next day.

And because this is the Freezer Food Challenge, nothing goes to waste.

The remaining lamb has been carefully portioned and stored in the fridge, ready to become the next dinner dish in this series. Think wraps, shepherd’s pie, lamb and veggie bowls… the possibilities are endless.

Stay tuned — the transformation is coming next.
