Instant Pot Pasta - How to Cook Pasta in Instant Pot

Learn how to cook Pasta in the Instant Pot with this informative how-to guide explaining the cooking time formula, pasta-to-liquid ratio, and pressure release technique. It's the ultimate pressure cooker pasta recipe for dinner, sides, soups, and meal prep.

We are a pasta-loving family. It's a dinnertime staple I make at least once a week and to be honest, I love it for ease and convenience. It's a wonderful staple to have around, especially for easy meal prep throughout the week.

But rather than the traditional stovetop method, I've discovered the tried and true technique of cooking pasta in the Instant Pot. It requires less time, less effort, and less mess, which checks off all marks in my recipe book! 🙂

Why Cook Pasta in The Instant Pot

I love cooking pasta in my Instant Pot for my family because:

• It's a complete one-pot meal since the pasta cooks directly in its own starchy liquid, for luxuriously creamy dishes - no draining required!
• It's a set-it-and-forget-it cooking technique that results in perfect pasta every time.
• One simple formula allows you to customize the pasta firmness to your desired tenderness.
• It's a hands-off method since there is no anticipating the water to boil or babysitting a hot stove so that you can accomplish more kitchen tasks in less time.
• There is no risk of starchy cooking water overflowing and the clean-up is as easy as 1-2-3!
• It's a meal-prep delight: I can cook multiple pasta shapes in separate containers using the pot-in-pot method, and use them in different recipes throughout the week.

Instant Pot Pasta Formula - General Rule of Thumb

Since different pasta shapes require different cook times, here is what works great for me:

Look for the suggested cook time on the box. Now, take the lower number and divide it in half. If an odd number is listed, divide that and round down. For example, if it says 7 minutes, divide that in half, which is 3.5, and round it down to 3.

This produces pasta that is well cooked and just right for my family. For an al dente pasta, or firm to the tooth, subtract one minute from that. For a softer and more tender pasta, simply add another minute to that cook time.

Whole Wheat or Gluten-Free Pasta: The cooking-time formula holds true for whole wheat and gluten-free pasta (brown rice, lentil, quinoa, etc.) varieties, too. Simply refer to the cooking time on the package and follow the calculation above.

Cooking Times for Different Pasta Shapes - How Long Does It Take To Cook Pasta in Instant Pot?

Here's an easy cheat sheet for you. By following the above rule of thumb, I've listed below a few pasta shapes and their respective cooking times in the Instant Pot:

Pin this chart for future reference:

*Cooking Time Tip: For small or thin pasta shapes with a short recommended cook time (i.e. capellini), it is possible to set the timer to 0 minutes for al dente pasta. The pressure cooker will come to full pressure, but will not hold pressure for any length of time.

How to Make Instant Pot Pasta

The steps for cooking pasta in the electric pressure cooker couldn't be easier! Simply:

Add liquid and pasta: Add the recommended amount of water, pasta, salt, and oil. If cooking short pasta (penne, rigatoni, etc.), give it a stir. If cooking spaghetti or other noodle-shaped pasta, break it in half and lay it in two batches in a criss-cross pattern. Do not stir.

Set cooking time: Close the lid in sealing position. Using the rule of thumb, calculate the cooking time for your specific pasta shape. Set Pressure Cook/Manual for the calculated pasta time.

Perform an intermittent quick release: After the cooking time is done, use the intermittent pressure release technique (explained above or in notes) and release all the pressure. Open the lid when the pin drops.

Rest, sauce, and serve: Stir the pasta and separate any clumps using two forks. Let the pasta rest for 3 to 5 minutes as this lets it absorb the leftover liquid.

If the liquid is too much for your liking, you can always drain the pasta.

For a simple and satisfying meal, stir in your favorite sauce, such as spaghetti sauce or pesto.

How Much Water To Use - How Much Liquid to Cook Pasta in Instant Pot?

The ratio of pasta to liquid is approximately 1:2. This can be water, clear chicken broth or vegetable stock, milk, whatever you desire. The breakdown goes as follows:

• 8 oz. pasta + 2 cups liquid
• 12 oz. pasta + 3 cups liquid
• 16 oz. pasta + 4 cups liquid

Note: Feel free to disregard this ratio if cooking pasta in a lot of liquid or sauce, such as in the case of soups and chilis. Simply follow the cooking times as mentioned above.

How To Release Pressure When Cooking Pasta

Because of the starchy cooking water in pasta, it creates a big mess after a quick release when it sprays out of the pressure knob. To avoid this, I follow one of the two methods listed below:

1. Intermittent Pressure Release

I release the pressure in bursts. This means, I press down (Ultra) or turn (Duo) the pressure knob partially to release pressure 1-2 seconds at a time, then stop. I repeat this until most of the pressure has been released and its intensity has gone down.

After that, when I do a full release of pressure, nothing squirts out of the knob.

2. NPR 5

Another way to avoid the starchy mess is to let the pressure release naturally for 5 minutes followed by a quick release. In those 5 minutes, quite a lot of pressure is released, so when you turn the knob, it won't be as intense.

However, if choosing this method, reduce the pasta cooking time by a minute to prevent overcooking it.

Easy Clean-Up After Cooking

It's important to clean the lid after cooking to rid of the excess starch and scum since this blockage can affect the next cooking cycle. To clean the lid, simply:

Wash the lid and thoroughly clean the pressure valve of the Instant Pot after cooking the pasta with a nonabrasive sponge. Wash it out with warm, soapy water and rinse clean.

Pasta Cooking Tips & Notes

• Use water, clear broth, or milk. Add enough liquid such that most of the pasta is submerged in the liquid. If using broth, reduce the salt by half and adjust the seasoning after cooking.
• Break long noodles in half. Break spaghetti, linguine, or any noodle-shaped pasta in half and lay in two batches in a criss-cross pattern. This allows the pasta to fit snugly and prevents clumping. Do not stir to prevent sticking.
• Follow the Instant Pot Pasta formula. For well-cooked pasta, take the lower number of the cooking time on the package and divide it in half. If an odd number is listed, divide that and round down. Subtract a minute from that for al dente pasta. Add one minute for softer pasta.
• Follow an Intermittent Quick Release. This prevents the starchy liquid from spraying through the pressure valve. After cooking, press down (or rotate) the pressure knob partially to release pressure 1-2 seconds at a time, then stop. Repeat this until most of the pressure has been released and its intensity has gone down. Finish with a full release of pressure.
• Alternatively, perform an NPR5. Let the pressure release naturally for 5 minutes followed by a quick release. If choosing this method, reduce the pasta cooking time by a minute to prevent overcooking.
• A few dry spots are okay. When you open the lid after releasing pressure, you may notice a couple of dry bits of pasta. This is normal. Simply stir everything, and break up larger clumps with two forks. This will help the pasta absorb the remaining liquid.
• Let the pasta rest after cooking. Once pressure is released and you've given the pasta a good stir, let it rest for 3-5 minutes. The residual heat will allow the pasta to finish cooking.
• Always add the cheese after pressure cooking: This prevents the cheese from clumping and sticking in the pot.
