  • Elbow Macaroni

What is evaporated milk?

Evaporated milk is the unsweetened version of condensed canned milk and has majority of the water removed from it. It also has no sugar added.

To make evaporated milk at home, add 3 cups of whole milk to a sauce pan. Bring it to a simmer for 25-30 minutes until it is reduced by half.

This allows the water content to be reduced and makes it more creamy.

Another alternative to evaporated milk is half and half which will make the cheese nice and creamy.

Instant Pot Pasta Rules

Water Ratio

Wondering how much water for macaroni in Instant Pot?

The general rule of thumb for the water ratio is 8 ounces dry pasta to 2 cups water.

Always be sure to press the pasta below the water level for even cooking.

Cook Time

Cook times are determined by taking the lowest time on the pasta package directions, dividing it in half, and subtracting 2.

If the lowest time on the package is an odd number, decrease by 1 to get an even number before dividing in half.

Example: It says to cook the pasta 11-12 minutes.

Since it is not an even number, decrease by 1 digit to get 10. Then divide in half to get 5, and subtract 2 minutes to equal 3 minutes total cook time.

How to Make Instant Pot Macaroni and Cheese

Add the elbow macaroni, water, and salt to the Instant Pot. Stir and then press the pasta underneath the water level in an even layer for even cooking.
