Spaghetti Sauce:

  • 2 tablespoon olive oil divided
  • 3 cloves garlic chopped
  • ½ onion (or 1 large shallot) chopped
  • 8 oz mushrooms sliced
  • 1 lb ground beef
  • 1 teaspoon salt divided
  • 28 oz can of crushed tomatoes
  • 14.5 oz can of diced tomatoes
  • ½ teaspoon onion powder
  • 1 teaspoon garlic powder
  • ½ teaspoon black pepper
  • 2 teaspoon Italian seasoning
  • 2 cups unsalted chicken stock (reduce salt if not sodium free)


  • 8 oz. Spaghetti


Sauteeing Onions and Mushrooms in the Instant Pot:

  • Push "Sauté" button and "Normal" speed on the Instant Pot. Add 1 tablespoon olive oil, garlic, onion (or shallot) and mushrooms. Sauté on Normal for 5-7 minutes with no lid on, stirring with a wooden spoon. If, during sautéing process, your instant pot signals "Burn', just add as splash of water.

Sauteeing Beef in the Instant Pot:

  • Add second tablespoon of olive oil and ground beef. Season with ½ teaspoon salt. Sauté on high for 5-8 minutes, breaking down beef with a wooden spoon.
  • Add crushed tomatoes, diced tomatoes, remaining ½ teaspoon salt, chicken stock, onion powder, garlic powder, pepper and Italian seasoning. Combine everything with mushrooms and shallots by mixing with a wooden spoon.

Adding Spaghetti to the Instant Pot

  • Add 8 oz spaghetti, breaking them by half (make sure to break them to prevent pasta from clumping during pressure cooking). Place spaghetti in layers,crosswise, alternating directions - this will prevent clumping as well.

Pressure Cooking Step by Step Instructions:

  • Turn the vent on top of the lid all the way to the back to "Sealing". Click "Pressure Cook"/"Manual" button. Set it on High. Set time to 8 minutes. At this time the pressure will start building (this is called preheat mode). This process will take a while, about 10-15 minutes due to so much liquid in the pot. Once the instant pot is getting close to reaching its optimal temperature, you will see steam coming out of the float valve The screen will show "On" for the duration of the preheat mode. It's not cooking at this point yet.
  • You will know when the preheat mode is over when the float valve pops up and seals itself. The steam will stop coming out. At this time you will hear the beep,  "On" reading on the screen will be replaced by "00:08", which is the number of minutes. This will start the countdown from 8 minutes until 0.
  • Once the countdown is over, the Instant Pot will beep several times and the digital display will show "L0:00". Push "Cancel" button to turn off heat warm mode.

How to do Natural Pressure Release Method:

  • Last step is to make sure the Instant Pot is depressurized before opening the pot. We will be using NPR - Natural Pressure Release method. After the cooking cycle of the Instant Pot Spaghetti is finished, there are a couple of things that need to be done prior to opening the lid.
    First, wait until the Floating Valve (metal pin) completely drops before opening the lid (about 10 minutes).
    Second, turn the Venting Knob from "Sealing" to "Venting" to ensure all the pressure is released before opening the lid (about 5-10 minutes).
    Third, open the lid.



Note: If you see steam coming out during pressure cooking, don't panic. This is perfectly normal.
