In the Instant Pot world, it's easy to confuse gallons and half-gallon measures- especially if you aren't measurement savvy. This article discusses how many ounces are in a gallon and which recipes to keep watch over.
How many ounces are in a gallon
In short, there are 133 fluid ounces in 1 gallon. This equates to approximately 16 cups or 4 quarts. Recipes such as our Instant Pot Pinto Beans with Ham Hocks requires a pint of liquid, however, it can be easily stretched to a half-gallon or more.
Similarly, you can easily use a gallon of milk in an Instant Pot such as our Homemade Hot Chocolate recipe, which uses 1 gallon of milk. The trick here is to use an Instant Pot that can hold all the ingredients without bubbling over.
We recommend using a 6 or 8 quart and depending on how many additional ingredients are required it may be best to use an 8-quart Instant Pot.
How to measure ounces in a gallon
Because a gallon requires 16 cups of liquid, you will either need to find a container large enough to hold that amount or a container a few steps below to prevent a tiring relay race.
For a gallon transfer, we recommend using a 1-gallon pitcher or wide mouth jug. For a step under, you can use an 8-cup coffee pot, or measuring cup.
You can also use an extra-large Tupperware bowl or container.
We also have a conversion measurements guide that helps you convert Instant Pot measurements with ease that will greatly help.
Here are a few Instant Pot recipes that can be used to stretch to a gallon or more:
- Ham Potato Soup
- Instant Pot Split Pea Soup
- Homemade Instant Pot Greek Yogurt
- Instant Pot Homemade Hamburger Helper
- Instant Pot Paprika Beef Tips
Our Instant Pot Paprika Beef Tips uses 2 cups beef broth with a 1/2 cup of milk, which can serve 6 people, so if you are looking to extend this to a party of 12 or more, you will need 6 cups of broth and a 1 1/2 cup of milk or more, including doubling the additional ingredients.
Another savory dish that can stretch to a gallon is Instant Pot Cheesy Potatoes, which uses 8 cups of shredded potatoes- which would be measured using dry measuring cups.
Again, dry ingredients must be measured in metal or stainless-steel cups because it will be hard to do in liquid containers unless you cut down the ingredients and pack them into the glass measuring dish.
And speaking of dry ingredients, when converting a smaller meal into a gallon or more, you must account for the expansion of dry ingredients as well. Take for example our Instant Pot Pork and Beans.
This recipe calls for 1 pound of Great Northern Beans, rinsed and dried. Dried beans expand to stretch this recipe to 12 or more servings. You will need both a gallon of liquid as well as a bit of wiggle room to allow the beans to stretch.
