Slow roast pork Cooking Time Calculator — Time, Temperature & Method

Slow roast pork Cooking Time Chart

Weight	Cooking time	Internal temp
1.5 kg	3 hr 30 min	88°C
2 kg	4 hr 30 min	88°C
2.5 kg	5 hr 30 min	88°C
3 kg	6 hr 30 min	88°C

🌡️ Stop guessing — check the real temperature

A fast digital meat thermometer is the only way to know your roast is safely and perfectly cooked. Pull it at the exact internal temperature, every time.

How This Calculator Works — Formula & Method

Source: standard UK roasting guidance · applied deterministically · verify with a thermometer

Constant	Value	Source
Min per 500 g	60 min (range 55–70)	UK roasting guides
Internal target	88°C / 190°F	FSA / thermometer
Base offset	30 min	Standard
Oven	220°C sear for 25 min, then 150°C	Method
Resting	20 min	Best practice

— Slow roast pork cooking time —
total_min = min_per_500g × (weight_g / 500) + base_offset
range = [lo_per_500g … hi_per_500g] × (weight_g / 500) + base_offset
conventional_oven = fan_temp + 10–20°C (same time)
fahrenheit = derived table from °C
— algorithm —
lookup(meat, cut, doneness) → point_estimate → guidance_range
→ internal_target_temp → verify_with_thermometer()

Public roasting guidance applied deterministically — this is not a food-safety authority. Always cook to the stated internal temperature, measured with a meat thermometer.
