Cook The Best Instant Pot Spaghetti Like This

Step 1: Sauté the Aromatics
Start by turning your Instant Pot to the sauté function. Add the olive oil and let it heat up. Once hot, toss in the finely chopped garlic and sauté for about 30 seconds until fragrant. Be cautious not to burn it!
Step 2: Brown the Beef
Add the ground beef to the pot, breaking it up with your wooden spoon. Sprinkle in the onion powder, Italian seasoning, salt, and black pepper. Cook until the beef is browned all over, stirring occasionally, which should take about 5-7 minutes.
Step 3: Add the Pasta and Liquid
Layer the uncooked spaghetti noodles on top of the browned beef. Do not stir! This is key to prevent the noodles from sticking together. Pour the 3 cups of water over the spaghetti, followed by the diced tomatoes and crushed tomatoes or pasta sauce, ensuring everything is evenly distributed.
Step 4: Cook Under Pressure
Close the lid of your Instant Pot and ensure the valve is set to sealing. Select the manual or pressure cook setting and set the timer for 8 minutes. The Instant Pot will take some time to come to pressure before it starts cooking.
Step 5: Quick Release and Serve
Once the cooking time is up, carefully do a quick release by turning the valve to venting. Once the steam has fully released, open the lid. Stir the spaghetti to combine everything well. Serve hot, and enjoy your delicious, homemade spaghetti!
Flavor-Forward Alternatives

- Swap ground beef for ground turkey or chicken for a lighter option.
- Add a splash of red wine to the sauce for a deeper flavor.
- Incorporate vegetables like bell peppers or mushrooms for added nutrition.
- Top your spaghetti with fresh basil or parsley for a fresh finish.
Easy-to-Miss Gotchas
- Ensure you don’t stir the spaghetti with the meat before adding the liquid. This helps prevent the noodles from clumping together.
- Always check the sealing ring in your Instant Pot to ensure it’s properly placed before cooking.
- Let the pressure release naturally for a few minutes if you have time; it can help enhance the flavor.
- Remember to adjust seasoning after cooking, as flavors can intensify or mellow out during the pressure cooking process.
Storage Pro Tips

For longer storage, you can freeze individual portions in airtight containers for up to 3 months. Just thaw overnight in the fridge before reheating, and you’ll have a quick meal ready to go!
