Pressure Cooking Times are determined by the size, and not the quantity of food!When you double or halve a recipe, such as the Garlic Cauliflower Mashed Potatoes, you don’t need to increase or decrease the cooking time – it remains the same!

One potato will take 10 minutes to pressure cook, and so will four potatoes, and so will 8 potatoes. That’s because the pressure cooking time is determined by the size and not the quantity of food.

In other words, the pressure cooking time is the amount of time the food requires to be cooked all the way to the center. So, a large potato will need 10 minutes of pressure cooking time, small potato 5 minutes, and a large potato sliced into small pieces also 5 minutes – no matter how many of them you pressure cook!

  • Cooking time doesn’t change.  That’s because the time is based on the size, and not the quantity of food.
  • Include minimum amount of liquid. Especially when cutting a recipe in half, don’t go below the minimum liquid (either state in your manual of 1 1/2 cups).
  • Don’t bring food over the Max.-full lines. Especially when doubling a recipe make sure not to fill the cooker more than..
    • 1/2 Full for rice, grains and beans
    • 2/3 Full for everything else

  1. So if I made the Pasta with Broccoli & Sausage One Pot recipe but only want to make half of it, the cooking time is still 5 minutes? But the recipe would be halved, of everything? 1/2 lb sausage, 1/2 lb pasta, etc? Even the tomato paste, garlic, etc.? Sorry, I’m new to using the Instant Pot. Any guidance would be appreciated. Thank you for the informative video. :)

    1. Yes, the cooking time remains the same – no matter the quantity. For example, the video shows potatoes, but in this case, it applies to pasta pieces – so a pound or half a pound will still need the same cooking time because all of the pasta pieces are the same size. The same goes for rice, for example, because all of the grains are the same size too! : )

      However, you’ll need to measure the water you’re putting in there because your Instant Pot will not easily reach pressure with anything less than 1 1/2 cups.

  2. I’m confused. Based on size and not quantity did you meant that the pressure cook does not depend on the mass but only the volume?

    How do I triple/double a recipe for sauce, you have any tips for that?

    1. I said that the cooking time depends on how long it takes for the heat to reach the center of the food – no matter how many of those foods you pressure cook.

      For a sauce, the same rule applies but the “pieces” in the sauce are significantly smaller – the cooking time remains the same you’ll need to just make sure not to go over the “max” line.

      Specifically for sauces, tho, that is not the only thing you should watch out for. My Bolognese, for example, has a certain amount of water added to help the cooker reach pressure and when you double or triple that recipe the additional liquid should not be multiplied. When in doubt, ask the recipe author how to multiply specific recipes, as they are aware of how all the components interact – or, at least, they should be! That’s a bit of knowledge will distinguish the original recipe author from someone who copied it, changed one ingredient, added their photo and posted it online, or an e-book. ; )
