Detailed Directions and Instructions
Step 1: Sauté the Onion
Set the Instant Pot to the sauté setting. Add a drizzle of olive oil, and once the oil is hot, add the chopped yellow onion. Cook the onion until it becomes translucent, which typically takes about 3-5 minutes.
Step 2: Brown the Ground Beef
Add 1 pound of lean ground beef to the pot along with 1 teaspoon of Italian seasoning. Stir the mixture and break up the meat as it cooks until it is browned and cooked through. If there’s any excess grease, carefully drain it from the pot.
Step 3: Deglaze the Pot
Turn off the Instant Pot. Pour in ¾ cup of water and use a spatula to scrape the bottom of the pot. This helps deglaze the pot and removes any stuck-on bits from browning the meat.
Step 4: Add Tomatoes and Sauce
Into the pot, add the undrained can of diced tomatoes and the jar of marinara sauce. Along with these, add 1 cup of water. Stir the mixture well to combine all the ingredients.
Step 5: Prepare the Spaghetti
Take the 8 ounces of spaghetti noodles and break them in half. Add the broken noodles to the pot, spreading them apart and crisscrossing them to help prevent sticking together.
Step 6: Submerge the Noodles
Gently press the spaghetti noodles into the sauce mixture until they are fully submerged. If you notice that some of the noodles are still sticking out, add a little more water to ensure they are covered.
Step 7: Cook Under Pressure
Close and lock the lid of the Instant Pot, making sure to set the valve to the sealing position. Cook the mixture on high pressure for 8 minutes.
Step 8: Release the Pressure and Stir
Once the cooking time is done, perform a quick release of the pressure. Carefully remove the lid, and then stir the spaghetti to mix it well with the sauce. Allow it to sit for a few minutes to thicken before serving.
Step 9: Serve
Serve the spaghetti hot, topping each portion with freshly grated Parmesan cheese as desired.

Cook techniques
Sautéing
Sautéing is a cooking technique that involves cooking food quickly in a small amount of oil or fat over relatively high heat. In this recipe, olive oil is heated in the Instant Pot, and chopped onion is added until it becomes translucent. This method enhances the flavor of the food by caramelizing the natural sugars.
Deglazing
Deglazing is the process of adding liquid to a pan to help loosen and dissolve food particles that are stuck to the bottom. After browning the ground beef, water is added to the pot to scrape any browned bits, which adds depth of flavor to the sauce.
Pressure Cooking
Pressure cooking uses high pressure to cook food quickly. In this recipe, the cooked ingredients are combined with water and spaghetti, and then the Instant Pot is sealed and set to high pressure. This method allows the spaghetti to cook evenly while absorbing the flavors of the sauce.
Quick Release
Quick release is a method used to release steam from the pressure cooker rapidly. Once the cooking cycle is complete, the valve is flipped to release the pressure, allowing for immediate access to the cooked meal without waiting for natural release.
Resting
Letting the dish sit for a few minutes after cooking allows the flavors to meld together and the sauce to thicken slightly. This technique ensures a more balanced taste and better texture for the spaghetti before serving.
