How to Use the Cooking Time Reduction Calculator
Enter the original cooking time, then select a size change and/or cooking method change. The calculator applies both changes together using a compound reduction formula to give you a realistic estimate of the new cooking time.
The most impactful change is switching to a pressure cooker, which reduces cooking time by about 60%. This is ideal for tough cuts of meat, dried beans, and stews. Combining it with smaller cuts can bring a 60-minute dish down to under 15 minutes.
Air fryers save about 20% over conventional ovens and preheat in 1–2 minutes versus 10–15 minutes for an oven, making them a practical choice for busy cooks.
