Ingredients
Base
- 500g beef mince (5% fat)
- 800g Maris Piper potatoes
- 1 tin chopped tomatoes (400g)
- 2 steam bags frozen mixed veg (approx. 500g total)
- 1 medium onion, chopped (approx. 150g)
- 80g frozen peas (½ cup)
- 4 tbsp olive oil (60ml / 54g)
- Salt and black pepper
Spices – First Stage (onions)
- 1 tsp mustard seeds (2g)
- 1 tsp garam masala (2g)
- 1 tsp cumin seeds (2g)
- 1 tsp garlic powder (3g)
- 1 tsp Worcestershire sauce (5ml)
Spices – Second Stage (mince)
- 1 tsp dried oregano (1g)
- 1 tsp dried basil (1g)
- 1 tsp garlic powder (3g)
- 1 tsp Worcestershire sauce (5ml)
Spice Conversion Table
| Spice | 1 tsp | 1 tbsp |
|---|---|---|
| Mustard seeds | 2g | 6g |
| Garam masala | 2g | 6g |
| Cumin seeds | 2g | 6g |
| Garlic powder | 3g | 9g |
| Dried oregano | 1g | 3g |
| Dried basil | 1g | 3g |
Method
- Preheat oven to 200°C.
- Parboil potatoes 8–10 mins. Drain and leave to cool completely (this converts some starch into resistant starch for better insulin sensitivity and gut health).
- Fry onions on low heat until softened.
- Add mustard seeds, garam masala, cumin seeds, garlic powder, Worcestershire sauce. Season with salt and pepper. Stir through.
- In the same pan, brown mince. Season.
- Add oregano, basil, garlic powder, Worcestershire sauce to mince.
- Add tinned tomatoes, frozen veg, and peas to mince. Stir.
- Simmer 10 mins.
- Transfer mince mixture to an oven-safe tray.
- Layer parboiled potatoes on top, spaced slightly apart (not mixed in—this keeps them crisp).
- Drizzle with olive oil and sprinkle with salt.
- Bake uncovered 30–35 mins until potatoes start to crisp.
- Finish under grill for 5 mins for extra crisp.
Why Cool the Potatoes?
Cook → Cool → Reheat
Cooling cooked potatoes converts some of the starch into resistant starch, which:
- Improves insulin sensitivity
- Supports gut health by feeding beneficial bacteria
- Reduces the glycaemic impact of the meal
This effect holds even after reheating.
Storage & Reheating
Storage:
- Divide into 4 airtight containers once cooled.
- Store in fridge for up to 4 days.
Reheating:
- Microwave on high for 4–7 minutes, stirring halfway through.
- Add an extra 30–60 seconds if needed depending on microwave power.
- Oven: 180c in oven for 25-30 minutes
- Only reheat once
- Cool for 30 mins then refridgerate
