Have you ever tried to make one pot pasta in the Instant Pot? This Instant Pot Spaghetti recipe was born when I went on a big spaghetti binge recently. I made a big batch of tomato sauce and had some gluten free spaghetti on hand. It took a bit of tweaking, but I hope you take advantage of this super simple, easy way to pressure cook spaghetti in tomato sauce.

The Ingredients

As I just mentioned, I used gluten free spaghetti, but you can use regular spaghetti too. I’ve even used this recipe with linguini. I’m not sure how this Instant Pot spaghetti would fare with a really thick meat sauce, but a smooth tomato sauce is what I’ve had success with. Let us know if you try other shapes or add meat!

Spray the Insert

I found out recently that sometimes the ‘burn’ warning can come on when preparing tomato based dishes in the Instant Pot. There is a certain chemical reaction that can happen with the base of the Instant Pot that causes this to occur. According to the manufacturers, spraying the insert with cooking oil can help prevent that from happening.

Pressure Cooking

This Instant Pot spaghetti is one of those set it and forget it type of recipes. Layering everything together is key. Add in your water, pasta, tomato sauce, and broth, then pressure cook it for 9 minutes. Simple! After it’s done, remove the lid and stir everything together. Depending on the thickness of your pasta sauce, you can set the Instant Pot to sauté and evaporate out some of the liquid while stirring. Garnish with your favorite cheese and fresh herbs!
