The rotini pasta can be swapped out for any pasta you have on hand. Spiral pasta is great for thin sauces but penne works well with this dish as well. The pressure cooking time is a very simple formula.

To determine pressure cooking time for pasta, divide the time in half that it says on the package and then subtract 1 minute.

Once the pasta is pressure cooked, there usually isn’t any need drain the liquid and in fact a little bit of liquid from the pasta is great to help sauces and other add in’s stick to the pasta.

Ingredients in Instant Pot Pesto Pasta

The ingredients used for this Instant Pot pesto pasta are easy to find and easy to put together to create this flavorful dish. For a full list of the ingredients with their measurements, check out the recipe card at the bottom of the post.

• Rotini Pasta (Penne pasta works great for this dish as well) – I prefer rotini pasta or other spiral pasta because the pesto gets into all the nooks and crannies and covers the pasta well.
• Butter
• Salt & pepper
• Spinach – rinsed, patted dry, and chopped
• Cherry tomatoes (grape tomatoes are a good substitution)
• Basil pesto – homemade or jarred, whichever you prefer!
• Cream cheese – softened cream cheese will melt into the pasta easier than using cream cheese right out of the fridge. Either way if fine but softened cream cheese saves a little bit of time.
• Parmesean – Shredded or grated works well.
• Chicken broth (you can substitute chicken broth for vegetable broth or for water if you wish)

How to Make Instant Pot Pesto Pasta

There are simple steps to make pasta in the Instant Pot and it starts by making sure that the dry pasta is completely submerged so that the pasta cooks evenly.

Rotini pasta is added to the inner liner and the chicken broth (or liquid of choice) is added on top. If needed, gently press the pasta down into the broth to submerge the pasta completely.

Once the pasta is submerged, the butter, salt and pepper are added to the pot. The ingredients are not stirred and the lid is closed as well as the vent.

The pressure cooker is then set to 4 minutes and once the pressure cook time is up, the pressure is slowly and intermittently released from the pot. Please refer to your pressure cooker manual for how to safely proceed with this step.

The lid is then removed and the cream cheese is stirred into the pasta. If there is a small amount of liquid left in the pot with the pasta, that is okay!

This will actually help the cream cheese and the basil pesto cling to the pasta noodles. The chopped spinach, cherry tomatoes, pesto, and Parmesan are then stirred into the pasta mixture.

When serving, serve with sprinkled Parmesan if desired. This Instant Pot Pesto Pasta can be served hot or cold.
